Babies are prone to this malformation because of the process during fetal development by which the abdominal organs form outside the abdominal cavity, later returning into it through an opening which will become the umbilicus. Hernias may be asymptomatic and present only as a bulge of the umbilicus. Symptoms may develop when the contracting abdominal wall causes pressure on the hernia contents. This results in abdominal pain or discomfort.

Between the ribs are fine parallel lines of growth and sometimes a few fine revolving lines. Below the periphery, in line with the posterior edge of the lip, there is a smaller, plain, angular rib, and around the umbilicus there is a strong nodulose rib. Between these ribs, the base is covered with fine revolving lines. Within the umbilicus are radiating raised lines which cross two or three small revolving ribs.

1998; 128(5):410. Free full text How exactly the metastases reach the umbilicus remains largely unknown.

The shell has a diameter of 2.5 mm. The solid, yellowish white, subtranslucent shell has a depressed convex shape. It is more flattened below. The umbilicus is almost covered.

With the patient supine you percuss along a transverse line from the umbilicus into the flank to establish the level of dullness that signifies the lower extent of bowel.

In contrast, Endothyrella affinis lacks the horizontal parietal plica and has four hair rows. Moreover, Endothyrella plectostoma has a narrower umbilicus and more elevated spire than Endothyrella affinis. Endothyrella sowerbyi has a wider umbilicus and a thinner peristome than Endothyrella plectostoma. Moreover, the spire is lower and the dorsal side is rather domed in Endothyrella sowerbyi (conical in Endothyrella plectostoma), and the main parietal plica is weaker or missing in Endothyrella sowerbyi.

It is sharply angled at the periphery, slightly arched across the base, apparently nicked at the point of the columella. The inner lip is arched, strengthened by a thin pad, reverted on the umbilicus so as to leave a groove behind it, with a slight tooth in front. From the body it bends very much over to the left, so as largely to cover the umbilicus. It then advances straight and is toothed in front.

Blanfordiceras is a strongly ribbed, evolute ammonite included in the perisphinctacean family, Neocomitidae that lived during the latest Jurassic. The shell of Blanfordiceras is discoidal, coiled evolutely with all whorls visible so as to have a broad umbilicus. Exposed whorls are ornamented with strong ribbing that arises from the umbilicus, bifurcating on the outer flanks and extending onto the venter. In general form Blanfordiceras is similar to Berriasella, although with a more rounded whorl section.

Cheiloceras is a subglobular to thickly lenticular goniatite with a closed umbilicus from the Upper Devonian and type genus for the Cheiloceratidae.GONIAT-Cheiloceras entry Cheiloceras is sometimes split into at least three subgenera. Cheiloceras (Cheiloceras) has evolute juvenile stages, the umbilicus closing later, while C. (Compactoceras) is subglobular with involute whorls in the early stage, later becoming compressed in form, and C. (Puncticeras) is involute in all stages. Eucheiloceras is another name for C. (Cheiloceras).

The ribs and spiral threads thus form a series of meshes or reticulations. The periphery and base of the body whorl are well rounded, sculptured, like the spaces between the sutures, by the axial ribs which continue prominently to the narrow umbilicus, and six subequal and subequally spaced spiral threads, with an indication of a very weak seventh within the narrow umbilicus. The ovoid aperture is moderately large. The posterior angle is obtuse.

Its edge is minutely denticulate. The oblique columella deeply enters the narrow umbilicus and is inserted in the center of the axis, slightly dentate above, bearing a narrow tooth below the middle, and terminating in a large, heavy bi- or triplicate tooth. The parietal area is covered by a white callus bearing numerous wrinkles, one or two of which enter the aperture. The umbilicus is surrounded by a radiately strongly plicate callus.

Seeking a new voice for herself in a uniquely contemporary style that declares "anything is possible," she founded Theater Discordia. Creating performance- art pieces that have been part of the L.A. Theatre Festival, and the L.A. Poetry Festival, she directed and wrote "Poeticus Umbilicus", "Poetry Discordia", "Return of Umbilicus", "We & They" and "Changing Flags." Her Theater Discordia evolved, with the participation of Peter Sellars, into a celebrated venue for experimental theater works.

The shells of Discus rotundatus in the adult stage measure in diameter and in height.AnimalBase Shells are reddish brown with darker cross bands, flat and densely ribbed. The umbilicus is quite wide, reaching about 1/3 of the shell diameter. Among the species of Discus in Europe and North America, Discus rotundatus is recognized by the alternating pattern of reddish brown spots, tight coiling of the whorls and broad and shallow umbilicus.

These are contabulate, the first whorl somewhat eroded, the two following whorls bicarinate, the penultimate and body whorl more or less tricarinate. The body whorl is sculptured with 24 spaced spiral striae with microscopic vertical striae in the interstices. The fourth, sixth and eighth striae below the suture on the body whorl are larger than the others and three or four striae near the umbilicus are closer together. The umbilicus is of moderate size.

The sharp outer lip shows on the interior some marks of the external cords and inserts into the top middle of the penultimate whorl. The columellar edge is slightly arched and thickened, somewhat angular at the bottom, and slightly reflected on the umbilicus. Solid test, thick, decorated over its entire extent, The thick, solid shell is decorated over its entire extent, except within the umbilicus, with numerous decurrent cords. These are tight, subequal, rounded.

The small, globose-conoidal shell measures 7½ mm. It is narrowly perforate, shining, solid, smooth, except for a few stride around the white umbilicus. Its color is pink, orange, purplish or olive-brown, generally with a series of white blotches alternating with self-colored darker ones below the sutures, a girdle of white blotches around the periphery and often around the umbilicus. The intervening spaces are irregularly strigate with darker zigzag streaks or unicolored.

The lip is edged inside by black, or black and white. The columella is arcuate, produced above in a heavy porcellanous callous deposit, half-surrounding the umbilicus and deeply notched in the middle. The shell of Cittarium pica presents a rather wide umbilicus, which is deep and devoid of sculpture, but spirally bicostate inside. The semicircular, oblique aperture is distinguishably nacreous inside as is the case in other Trochoidea, and is circular.

The umbilicus is wide and mostly covered by the reflective columellar margin. The width of the shell is 30–90 mm. The height of the shell is 30–55 mm.

This monophyletic clade is sister to the remainder of the Sempervivoideae subfamily, and its three sublineages, Telephiae, Phedimus/Rhodiola and Umbilicus form a polytomy with the rest of the subfamily.

The white shell is thin, transparent, and very glossy. The length measures . The five to six whorls of the teleoconch have deep sutures. The umbilicus is very distinct, but small.

The body whorl increases rapidly in size and is rotund at the periphery. The umbilicus goes deep. The aperture is rotund and has a fine lip. The columella is simple.

The angulate shell aperture is small. The outer lip is crenulate. There is no umbilicus. The concave operculum is small and circular and has numerous pinnate bristles on its edges.

The shell is subdiscoidal with a broad umbilicus. The last whorl is separate from the rest of the shell and features a tube-like snorkel structure. The operculum is multispiral.

The umbilicus is narrow and partly covered by the reflected columellar margin. The width of the shell is 30–50 mm. The height of the shell is 30–45 mm.

The umbilicus is perforate, with smoothish walls. The aperture is half as high as the shell. It is oblique, nearly circular, with sharp, simple, slightly expanded edges.Dall W. H. 1889.

Endothyrella tricarinata differs from Endothyrella plectostoma by the larger size, more conical dorsal surface, narrower umbilicus, the shouldered whorls, the presence of only four rows of hairs, and the stronger sculpture.

The aperture is oval, pointed at the base. The columella is curved. The tooth is small and indistinct, tubercular, placed on the upper part of the columella. There is no umbilicus.

The columella is twisted. And upon some specimens are observed several crenulations towards the base of the inner lip which partially covers the umbilicus. The periostracum is thin and reddish.Kiener (1840).

It contains six prominent spiral lirae and is minutely lirate around the umbilicus. The ovate aperture is transversely dilated, and silvery within. The peristome is acute. The white columella is thickened.

Its top is attached to the penultimate whorl. it covers mostly the umbilicus. The brownish operculum is rather thick and consists of polygyrous spirals.J. Thiele, Die antarktischen Schnecken und Muscheln pp.

The 5½ whorls are convex and tubular. The body whorl is slightly convex beneath and carinated around the umbilicus. The aperture is oblique, and circular. Its margins are thin and arcuate.

These snails lay their eggs into the umbilicus of their own shells.Heller J. (2001) Life history strategies. page 419. 413-445. In: Barker G. M. (ed.) The biology of terrestrial molluscs.

The columellar lip is slightly patulous, bending flatly over the umbilicus, and then advancing in a straight line to the point of the columella, where it is slightly angulated just where the beaded umbilical spiral ends. The umbilicus is funnel-shaped, rather open, but a good deal contracted within, sharply scored with the lines of growth. The operculum is yellow, horny, very thin, consists of 7 to 8 whorls. The animal has a uniform light colour.

Spirals: There are three to five slightly raised remotely beaded threads, of which one lies a little below the suture and one at the periphery forming a carina, of which the beads are much smaller and closer set, sometimes evanescent. Another one with beads like the first, defines the umbilicus. Within the umbilicus there is a strong spiral ridge. The whole surface is covered with fine rather sharp threads, whose partings are twice as broad as themselves.

The shell is composed of four whorls, marked with none to three spiral carinae. The spire is normally low and umbilicus is wide, exposing all the whorls to the apex. There is great variation in the height of the spire and with its increase there is a proportionate decrease in the width of the umbilicus. The apical two whorls are flat and planulate, smooth and shining, unmarked with carinae even when the remainder of the shell may have three.

The aperture is rather oblique, a little higher than it is broad, slightly flattened above, and a very little angulated at the junction of the outer lip to the body. The thin lip is very little reflected on the umbilicus, porcellaneous on the edge, with a very slight pearly marginal callus, which is continuous across the body, and nacreous within. The large umbilicus is funnel-shaped, quickly contracting, but leaving the whole inner spire visible.Watson, R. B. 1879.

This is roughened by the crossing of the growth lines, which are elsewhere inconspicuous. On the base surrounding the umbilicus there are also four more prominent carina, about equal in size and evenly separated by wide, slightly concave interspaces. The first one is situated about the middle of the base, and the last one well up in the umbilicus. On all of these, the lines of growth are so conspicuous as to give them a distinctly beaded appearance.

In 1996, UMBILICUS and Ithaka Darin Pappas were as the cover story of the American culture publication Speak Magazine (founded by Dan Rolleri and graphically designed by renowned art director, Martin Venesky). A close-up navel photograph from the UMBILICUS series appeared on the cover of issue #3. The image was considered controversial and disturbing causing the edition to be immediately returned by hundreds of distributors and newsstands. It was the worst-selling issue in Speak Magazine's history.

In all, the inside of the umbilicus and the columella are tinged with green. The spire is elevated, conical, rather obtuse. The sutures are impressed. The five to six whorls are convex.

This can also occur in the esophagus, causing esophageal varices, and at the level of the umbilicus, causing caput medusae. Between 44% and 78% of patients with portal hypertension get anorectal varices.

The size of the shell varies between 2 mm and 3 mm. The shell has a turbiniform shape. The umbilicus is deep perspective. The elevated spire contains four, a little convex, whorls.

They are marked with microscopic growth lines. The periphery of the shell is more or less distinctly keeled or angulated. The shell shows an impressed spiral line. The small umbilicus goes deep.

The outer and basal lips are plicate within. The columella is as in Clanculus guineensis Gmelin, 1791 but longer. The narrow umbilicus is deep. The parietal wall is slightly calloused and is wrinkled.

The body whorl is encircled by chestnut-dotted carinae. The base of the shell contains a purple-brown zone. The umbilicus is perspective, margined by a somewhat tubercular cord. The aperture is subcircular.

The oe which defines the umbilicus is more sharply beaded than the rest. Longitudinals: Below the suture and near the umbilicus the surface is sharply but delicately puckered, and these puckerings, strong in the early whorls, are in the later faintly continued across the whorls as lines of growth. The colour of the shell is yellowish white, with a brilliant nacreous sheen shining through the thin superficial calcareous layer, which becomes more opaque in drying. The high spire is scalar.

The aperture is subquadrangular, with the outer and basal margins sharp, irregular by the ends of the spirals The columella is nearly straight, with a distinct angle where it joins the basal margin. This angle is caused by the umbilical rib, its upper part is slightly reflected over the umbilicus and covers it partly. The umbilicus is somewhat roughened by the lines of growth. The whole shell is covered with irregular, interrupted, hairlike lines of growth, visible only under a lens.

The columellar margin is reflected at the angle near the umbilicus. This is a most beautiful species, smooth, shining, ornamented with a beautiful regular series of white spots upon a bright fawn-coloured ground. At the periphery, which is not angled, the shell is whitish, with another line of zigzagged pale-brown markings more flame-shaped at the base. Around the deep umbilicus, the margin of which is very slightly angled, a row of dark-brown flames alternates with the white.

The body whorl descends anteriorly and is rounded at the periphery. The base of the shell is convex, with revolving lirae more superficially and much more closely cut into granules than those of the upper surface, and also broader, flatter, and equal in size. These number 6 to 7, one or two around the umbilicus. The umbilicus is white, dotted with yellow or reddish, the remainder reddish-brown, sparsely articulated on the ribs with white, sometimes radiately marked with narrow white stripes.

The columella is oblique, with a tooth-like fold above, solute, and deeply inserted upon the side of the umbilicus The middle portion is concave, with a reflexed subdenticulate edge, ending beneath in a minute denticle. The profound umbilicus is smooth and polished within, bordered by a strong rib bearing 6 or 7 projecting white teeth, the upper one the largest.

The aperture is quite oblique, rounded-ovate, angular above, broadly rounded below, with a thin iridescent layer of nacre within. The outer, basal and columellar margins are rather thin, curved, the latter joined to the upper margin by a thin white parietal callous. The narrow umbilicus is not bounded by an angle.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia This dull whitish little shell may be known by its finely striate surface, narrow umbilicus, short spire and globose-turbinate form.

The size of the shell varies between 5 mm and 8 mm and the height of the shell is equal to its width. The shell of this mollusc is moderately solid, with angled whorls. The last whorl has seven or eight spiral ribs.

The base of the shell is nearly flat, and sharply carinate at the periphery. The umbilicus is funicular, deep, the verge carinate. The aperture is quadrate, slightly oblique. Its margin is thin, sharp, and simple.

The aperture is roundly ovate. The sharp outer lip is convex. The inner lip spreads as a distinct callosity over the body, and sometimes seals the umbilicus partly or wholly up. The columella is concave.

The shell grows to a length of 2.1 mm. The thin shell is nearly transparent, glossy, with microscopical growthlines. There are four, rather swollen whorls with a deep suture. The umbilicus is small and narrow.

The periphery is obtusely angulated, the angle showing at the base of the spire whorls. The umbilicus is extremely small, almost covered. The columellar tooth is strong and conspicuous. The outer lip is grooved within.

When this occurs, there can be an externally visible dilation of the paraumbilical (and perhaps even the thoracoepigastric veins) which leads to the appearance of "Caput Medusae". Caput Medusae is a clinical sign that is recognized by the physician by the characteristic appearance of distended veins emanating from the umbilicus of the patient. The shape of these veins and their arrangement around the umbilicus is said to resemble the snake-like hair of the mythological Greek Monster, Medusa. "Caput Medusae" [Latin] means "Head of Medusa".

Map (1926) of the western end of the Roman Forum: the Volcanal is indicated between the Arch of Severus and the stairs of the Temple of Concord, just northwest of the Umbilicus and Rostra. The site identified by Boni as the Vulcanal is today protected by a modern gray roof. The excavation is just off the southwest corner of the Arch of Severus and adjacent to the truncated masonry cone of the Umbilicus Urbis. The ruins of the (mostly reconstructed) Rostra Augusti are visible just beyond.

The cloaca is, for a time, shut off from the anterior by the cloacal membrane, formed by the apposition of the ectoderm and endoderm, and reaching, at first, as far forward as the future umbilicus. Behind the umbilicus, however, the mesoderm subsequently extends to form the lower part of the abdominal wall and pubic symphysis. By the growth of the surrounding tissues the cloacal membrane comes to lie at the bottom of a depression, which is lined by ectoderm and named the ectodermal cloaca.

The columella is oblique, nearly straight, with an obsolete, scarcely perceptible fold above, inserted upon the side of the umbilicus, not in its center. The smooth umbilical area is white or yellow. The false-umbilicus is deep and narrow, but partly filled by a white callus, not tapering to a point.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia Specimens from rocky shores are often eroded and encrusted with coralline algae, while those from shell, gravel, or cobble substrata are usually clean.

The length of the shell reaches 11 mm. The shell has a depressedly conoidal shape. It is sharply keeled, with a flat base and large umbilicus. It is nacreous under a thin, transparent, yellowish-white layer.

Zonitoides excavatus is smaller than Zonitoides nitidus. The umbilicus is extremely wide and perspectivically open (as is the case in Discus rotundatus). The shell is weakly brown, slightly transparent, with radial streaks. The animal is dark.

The whole surface is distinctly cancellated. The spiral striae are very minute and close together, with 30-50 on the body whorl. The longitudinals are much thicker and wider apart. The umbilicus is wide and deep.

The height of the shell varies between 19 mm and 35 mm. The conical shell has straight outlines. The base of the shell is flat, with a deep, funnel-shaped umbilicus. The shell is rather solid.

Oxydiscites is a genus of ammonites from the Upper Jurassic Kimmeridgian included in the Ochetoceratinae, Oppeliidae. The shell is involute, compressed, with a minute umbilicus, sharp venter with a tall finely toothed keel, and faloid ribbing.

The umbilicus and its margin are pure white, the aperture nacreous green.Verco, J.C. 1904. Notes on South Australian marine Mollusca with descriptions of New Species. Part I.; Transactions of the Royal Society of South Australia v.

The outer lip is lirate within. The basal lip is curved and subdenticulate. The short columella is hardly perceptibly folded above and dentate below. The umbilicus perforates scarcely deeper than the insertion of the straight columella.

The body whorl is strongly rounded and covers almost the whole shell. The aperture is rather ovate and has a smooth outer lip. A siphonal canal is lacking. The umbilicus is partly covered with a callus.

Later, or outer, whorls are smooth with convergent sides. The outer rim, or venter, is rounded. Embracement of previous whorls by the next is slight to mild. The umbilicus is rather wide, with an abrupt edge.

The aperture is roundly ovate, slightly longer than broad and rounded anteriorly. The peristome is not continuous. The peristome is sharp, simple, slightly reflected near the columella, suggesting a faint umbilicus. The suture is slightly impressed.

The area about the umbilicus has a pinched-in effect. The base is surrounded by a somewhat tumid area. The aperture is large, broadly oval, somewhat flaring at the anterior lateral angle. The posterior angle acute.

A secondary sculpture of fine radial laminae overruns the whole shell. The circular aperture is oblique and guarded by a broad outstanding varix. The umbilicus is broad and perspective. Hedley C. (1915), Studies on Australian Mollusca.

The outer lip is formed by the last radial rib. The inner lip is a little expanded and reflected. The umbilicus has a narrow perforation. Charles Hedley, The Mollusca of Mast Head Reef, Capricorn Group, Queensland.

The outer lip is sharp and thin, not patulous, not descending, advancing at its junction with the body whorl, then retreating so as to form the broad open sinus, acute angled at the periphery, slightly arched across the base, nicked close to the point of the pillar. The columellar lip is arched, strengthened by a thin pad; reverted on the umbilicus so as to leave a slight groove behind it, it has a slight tooth in front. From the body whorl it bends very much over to the left, so as largely to cover the umbilicus, and then it curves over to the right to join the outer lip on the base at an obtuse angle. The umbilicus is small, oblique edged, funnel-shaped, nearly covered by the columellar lip, contracted within, scored with hair-like lines of growth.

The sculpture is usually finely reticulated, that is resulting in a matt surface. The umbilicus is deep. Apertural lip, callus and apertural fold are very well-developed (callus is very much elevated). Parietal wall has two lamellae.

The white semicircular aperture has a nacreous gloss. The thick outer lip has no inner lirae. The columella shows two folds with a conspicuous tooth close to the siphonal canal. The umbilicus is closed by a callus.

The shell contains four, spiral, smooth and shining whorls. The body whorl is nearly smooth but showing a slight tendency to bear furrows or lines radiating from the suture. The umbilicus is small. The aperture is round.

The Brazilian species, alongside Eoborus charruanus from Uruguay, are the oldest fossil record of the family. The small size and large umbilicus of Eoborus are its most remarkable characteristics; it is considered primitive in the family Strophocheilidae.

The umbilicus is rather large and deep. The anal perforation has raised margins. it is moderately long, rounded behind, pointed in front, with a very distinct callosity on the inner side.G.W. Tryon (1890), Manual of Conchology vol.

The spirals are usually articulated with rose-red and opaque white or greenish-yellow. The base is rounded and finely spirally threaded. The umbilicus is not carinated nor marked by special sculpture. The aperture rounded and oblique.

The outer margin is obtuse and subcrenulated. The basal margin is plicatulate. The columella is disjoined and prominently denticulate above, oblique, with 1 or 2 tubercles where it joins the basal margin. The white umbilicus is narrow.

The color of the shell is white, with a pink or blue nacre glowing through. The whorls are rounded, flattened in front of the suture. The base of the shell is rounded. The wide umbilicus is funicular.

It is rounded at the periphery, depressed on the base and umbilicated. The umbilicus is very narrow, white and encircled by a white zone. The rounded aperture is oblique and simple. The peristome shows a light thickening.

The outer lip is rather thick. The columella is stout, thick, somewhat flexuose and reflected. It is provided with a strong fold a little anterior to the umbilicus. The parietal wall is covered by a thin callus.

The height of the conico-turbinate shell attains 10 mm, but is usually less than 5 mm. Its typical characteristic is the subsutural angulation and the cord around the umbilicus formed by double rows of rounded tubercles.

The orbicular shell is, depressed, smooth, and polished. The axis is imperforate. The columella is spirally twisted above, forming a false- umbilicus, with a simple margin. The columella has an edentulate edge and ends in a point.

The suture is distinctly marked. The aperture is large and round. The outer lip is thin, edged with a thin band of white, inside iridescent. The columella is subvertical, semicurved, expanding as a callus over the umbilicus.

Their interstices contain raised spiral threads, which grow coarser on approaching the umbilicus. The protoconch contains 1½ whorl, concluding with a prominent varix. The three whorls are tabulate above, and rounded below. The body whorl descends rapidly.

The base is sculptured with about twelve even-spaced ridges, similarly overridden. The umbilicus is narrow, bounded by a thickened rib, only developed in the adult; inside white. The aperture is subquadrate. The outer lip is thin.

The suture is distinct. The whorl in front of it narrowly marginate. The polished surface of the shell is smooth, except for fine incremental lines. It shows about ten faint grooves around the very narrowly perforate umbilicus.

The height of the shell attains 0.8 mm, its diameter 0.8 mm. The yellowish white shell has a helicoidal shape. Its umbilicus is narrow. The shell contains 2½ whorls, slightly flattened at the periphery and then rounded.

The base of the shell is quite short, decidedly rounded, and umbilicated. The umbilicus is partly covered by the revolute columella. The aperture is large, very broadly oval, and somewhat effuse anteriorly. The posterior angle is obtuse.

The nodes on the upper carina become little raised hollow rounded squamae on the second whorl. The aperture has a reflexed and thickened margin. The umbilicus is very wide and spirally dentate. This shell is nacreous within.

The double basal funicle is remarkable. The inner funicle is swallowed by the umbilicus and its presence is only indicated by the callus on the aperture. The outer funicle is unusually faint.Records of the Australian Museum v.

For terms see gastropod shell. The 4.5-6 x 7-13 mm shell is thin and a light horny yellowish colour. It is whitish near the umbilicus and very shiny, almost smooth. The outline is almost globulous.

An inconspicuous lira borders the umbilicus, which has a shallow groove just above it. Colour: chestnut-brown, with dark-brown spiral hair-lines of varying width; dotted with tiny white spots, which, below the suture, are aggregated into small pyramidal blotches with their apex upward, six in the body whorl. A white band, scalloped on both edges of these aggregated dots, encircles the periphery. An articulated white-and-brown spiral ornaments the lira bordering the umbilicus, a second lies just outside this, and another with more distant double white spots beyond.

The base of the shell is rounded with a large spiral, deep umbilicus, having one entering a spiral keel which ends at a projection of the pillar lip. The verge of the umbilicus is rounded and spongy. Outside of this ridge in the young it is constricted by a row of pits between which and the periphery are some obscure spirals in some specimens. The aperture is circular within, and when fresh, brilliantly pearly, but the pearly coating is very thin and seems to disappear in dead shells.

The inner lip is thickened and reflected, especially at its junction with the body where it almost covers the umbilicus. The columella is much curved, and thins gradually out to its junction with the base. The umbilicus is large and funnel-shaped on the base, deep, but small further in, contracted by a spiral white columellar pad, and more than half covered over by the columellar lip. The operculum is rather thin, horny, yellow, with ten or twelve very gradual turns, which are strongly defined by a thickened line.

The spiral lirae increase in number, to about 10 weaker spirals on the upper part and 4 or 5 stronger ones at the lower part of the upper surface, and numerous intermediate ones. Below the rounded periphery appear two or three more remote lirae, with intermediate ones and numerous, regular, flatter lirae on the convex basal part, becoming broader towards the umbilicus. The whole shell is crossed by oblique, fine, but conspicuous growth-striae. The umbilicus is narrow, in the front view concealed by the columellar margin, with rather smooth walls.

In the case of adjustable gastric banding, most SILS implants to date have utilized a 4 cm incision below the patient's left rib. However, other surgeons have been able to locate a single incision in the umbilicus – trans- umbilical gastric banding – which leaves no visible scar on the external abdominal wall. On February 14, 2009, the UK's first SILS implantation of a gastric band was performed by the pioneering surgeon Professor Franco Favretti and his Healthier Weight team. The patient, a 50-year-old female, received a gastric band (LAP-BAND) implanted through the umbilicus.

On the base there are about thirty spirals, more crowded, flattened, and irregular than above, and the edge of the umbilicus is defined by another whitish fillet, ornamented with about thirty oblong beads. One or two smaller and more faintly beaded threads lie within the edge of the umbilicus. Longitudinals: There are of these on the last whorl about 120. They are flexuous, marking the lines of growth, rather stronger, more regular and more distant than the spirals, which run over the top of them and form little white nodes at the crossings.

The rectus abdominis muscle is crossed by three fibrous bands called the tendinous intersections or tendinous inscriptions. One is usually situated at the level of the umbilicus, one at the extremity of the xiphoid process, and the third about midway between the two. These intersections pass transversely or obliquely across the muscle; they rarely extend completely through its substance and may pass only halfway across it; they are intimately adherent in front to the sheath of the muscle. Sometimes one or two additional intersections, generally incomplete, are present below the umbilicus.

Cutaneous endometriosis is characterized by the appearance of brownish papules at the umbilicus or in lower abdominal scars after gynecologic surgery in middle-aged women.James, William; Berger, Timothy; Elston, Dirk (2005). Andrews' Diseases of the Skin: Clinical Dermatology. (10th ed.). Saunders. .

It advances on the body whorl, then retreats so as to form a feeble sinus, bending at the same time shortly but sharply to the right into the umbilicus and then advancing straight forward, but a little toward the left, to its junction with the outer lip at the base. The funnel-shaped umbilicus is open- mouthed, oblique edged, straight-sided, deep and contracted internally. Its edge is sharply defined by a spiral thread, and is obliquely scored by the longitudinal ribs. Farther in, its walls are marked by hair-like lines of growth and faint spirals.

Umbilicus horizontalis, the horizontal navelwort, is a fleshy perennial flowering plant in the family Crassulaceae (in the genus Umbilicus) native to the eastern Mediterranean region in rocky habitats. Horizontal navelwort grows to an average of high. The thickly clustered, bell-shaped flowers are pale green, and grow in a raceme perpendicular to the spike, unlike common navelwort, whose flowers droop (thus the term "horizontal"). The plant often grows on shady walls or in damp rock crevices that are sparse in other plant growth, where its succulent, dark green leaves develop in rosettes that are about wide.

When the axis of coiling is hollow (perforate spire) the opening at the base constitutes the umbilicus. The umbilicus varies greatly in size, and may be wholly or in part covered by an expansion or callus of the inner lip (Natica). Many Recent shells, when the animal is alive or the shell is freshly empty, have an uppermost shell layer of horny, smooth, or hairy epidermis or periostracum, a proteinaceous layer which sometimes is thick enough to hide the color markings of the surface of the shell. The periostracum, as well as the coloration, is only rarely preserved in fossil shells.

The shell of the sea snail Neverita josephinia has an umbilical callus which almost completely fills the umbilicus, leaving only a groove open. A callus is an anatomical feature that exists in some mollusk shells, a thickened area of shell material that can partly or completely cover the umbilicus, or can be located as a coating on the body whorl near the aperture of the shell (i.e. a parietal callus or columellar callus). A callus exists in the shells of various species of gastropods (snails) and also in the shells of several species of Nautilus, a cephalopod.

Generally, the duct fully obliterates (narrows and disappears) during the 5–6th week of fertilization age (9th week of gestational age), but a failure of the duct to close is termed a vitelline fistula. This results in discharge of meconium from the umbilicus. About two percent of fetuses exhibit a type of vitelline fistula characterized by persistence of the proximal part of the vitelline duct as a diverticulum protruding from the small intestine, Meckel's diverticulum, which is situated about two feet above the ileocecal junction and may be attached by a fibrous cord to the abdominal wall at the umbilicus.

The Mads then abandon their plan to kill Mike, and instead use him as the new human test subject. Mike became the regular host for the remainder of the series' original run. In season six, the show introduced a device usually referred to as the Umbilicus, although in some episodes it was referred to as either the Umbilicon or the Umbiliport. The Umbilicus was a long tether that connected the Satellite of Love to the underground lair Deep 13, and allowed objects to be sent back and forth between Mike and the mad scientists who had stranded him in orbit.

The base is nearly flat. The oblique aperture is smooth within. The oblique columella is sinuous and bidentate. The umbilicus is surrounded by a white callus, bearing inside a strong spiral rib which terminates in a denticle about the middle of the columella.

The basal lip is straight, very thick, obtuse, crenulate, lirate inside. The columella is arcuate, ending below in a point or tooth. The umbilicus is white within. The young specimens have a minute smooth, rounded, rather elevated dextral nucleus, and bicingulate periphery.

The width of this large gastropod shell is 130–285 mm. The shell has a broadly conoid shape with a convex base. It is moderately umbilicated, the umbilicus penetrating to the apex. It is a little plicated within by the prominent growth lines.

The white umbilicus is narrow. The surface is lusterless. The lirae are rather coarse, broad and flat. The lower right hand margin of the aperture is decidedly produced, and the base is usually somewhat notched or emarginate as in the European Gibbula tumida.

The shell in this genus is like the shell of Diloma but rather more conical and less nacreous. The coloration is variegated, consisting of fine lines of dark on a lighter ground. The columella is generally green. The umbilicus is perforate or subperforate.

Eowellerites is genus of ammonoid cephalopods belonging to the Welleritidae family. Species belonging to this genus lived in middle Pennsylvanian (Moscovian). Its fossils were found in USA and Japan. It had thinly discoidal shells with a quite wide umbilicus (U/D = 0.3 - 0.5).

The umbilicus is either not apparent, or very small. The columella is not thickened, and the shell itself can be thin or thick. The shell aperture is oval to ear-shaped. When viewed laterally, the outer lip of the shell bends forward.

Pseudocenoceras is compressed, smooth, with subrectangular whorl sections, flattened venter, and a deep umbilicus. The suture crosses the venter essentially straight and has a broad, shallow, lateral lobe. The siphuncle is small and subcentral. Pseudocenoceras is found in the Crimea and in Libya.

The height of the shell attains 17 mm, its diameter 20 mm. It is a rather solid, umbilical shell. Its basic color is tan with sole lighter and darker spots on the spiral cords. The inner lip is slightly recurved toward the umbilicus.

The height of the shell attains 21 mm, its diameter 22 mm. The thin, perforate shell has a conoid-convex shape. Its apex is obtuse, thin. It is dark slate-gray, buff around the umbilicus, with spots of dull black below the periphery.

The growthlines are somewhat leaning forward with respect to the direction of the cone. The sculpture shows only fine microscopic spiral striae. The outer lip is straight adapically and gently curved towards the columella, which is nearly straight. The umbilicus is lacking.

It is marked by three spiral cords and a slender raised thread about the umbilicus. The channels bounding the peripheral cord and those of the base are crossed by riblets as on the spire. The aperture is large. The posterior angle is obtuse.

The shell is bullate, fairly thick, white, spirally striate, with a well- developed periostracum. There is no spire and no umbilicus. The columella is smooth and simple. The aperture extends for the whole length of the shell, and is narrower above than below.

The posterior angle is acute. The thin outer lip is broadly curved. The columella is slender, curved, and reflected, free from the base, forming a suggestion of an umbilicus;. Thecolumellar fold is slender, situated a little below the insertion of the columella.

This might cause acne, subcutaneous fat in face decreases. Pubic hair extends to thighs and up toward umbilicus, development of facial hair (sideburns, beard, moustache), loss of scalp hair (androgenetic alopecia), increase in chest hair, periareolar hair, perianal hair, leg hair, armpit hair.

The species in Syrnola are medium sized and slender. Their shell is subulate and polished, marked by fine lines of growth and microscopic spiral striations. It doesn't contain an umbilicus. The whorls of the teleoconch are flattened and increasing regularly in size.

The suboval aperture is moderately large, and somewhat effuse anteriorly. The posterior angle is obtuse. The outer lip is thin. The columella is slender, curved, reflected partly over the moderately large umbilicus and provided with a strong, acute, oblique fold near its insertion.

Beside these there are three very strong carinae;. One forms the margin of the nearly flat spire, the second extends horizontally just below the periphery. The space between them is deeply excavated. The third forms the edge of the funicular, narrow, deep umbilicus.

It is very finely undulately striate all over. The four whorls are angular above, coronate and radiately ribbed, rounded below, and furnished with two rounded obsolete granular keels. The umbilicus is very ample, with an elegantly dentate margin. The orbicular aperture is toothed.

Indonautilus is an involute nautilid from the Middle and Upper Triassic. (Anisian-Norian), with a small or occluded umbilicus and subrectangular whorl section belonging to the Liroceratidae (Clydonaulilaceae). Flanks are slightly bowed, converging on a flattened venter. Ventro-lateral shoulders are narrowly rounded or angular.

The umbilicus is open and not deep, and slightly excentric at the last whorl. Fresh shells have very faintly visible spiral lines under high magnification, about 10 spiral lines per radial riblet, 100-150 lines/mm.The animal is slender and blackish. The tentacles are black.

Umbilicus schmidtii is a flowering plant in the family Crassulaceae. The species is endemic to Cape Verde.Oromí, Martín, Zurita & Cabrera, 2005 : Lista preliminar de especies silvestres de Cabo Verde: Hongos, Plantas y Animales Terrestres. Gobierno de Canarias, Consejería de Medio Ambiente y Ordenación Territorial, p.

They are crossed by concentric ribs, running over the whole base and making the cords crenulated. The funnel-shaped umbilicus is pervious. Its wall shows concentric, riblike striae, and a spiral, beaded cord near the base. Its larger diameter occupies ⅓ of that of the shell.

The shell grows to a length of 10 mm. The shell has a conical shape, with a broad and tumid base and a wide narrowed umbilicus. The surface is cross-hatched like a file. When fresh, the shell is translucent with a pearly sheen.

Congenital umbilical hernia is a congenital malformation of the navel (umbilicus). Among adults, it is three times more common in women than in men; among children, the ratio is roughly equal. It is also found to be more common in children of African descent.

The main opening of the shell or the aperture is sometimes quadrangular in shape. There is a sharp lip inside the aperture which is white in color. The umbilicus is clearly visible, open and wide. The width of the shell is 4.5-5.5 mm.

The size of the shell varies between 6 mm and 10 mm. The rather solid shell is imperforate but excavated at the place of the umbilicus. It has a depressed-conical shape. It is whitish, with numerous spiral bauds and lines of purplish-brown.

The base of the shell is rounded. The shell lacks an umbilicus. The columella is nearly straight, with a strong tooth near its base. The rounded aperture is oblique, a little descending above, with six or eight stout lirae ending in tooth-like nodules.

The body whorl is dilated, subangulate above, depresso-carinated at the periphery, convex beneath and ornamented with 9 concentric reddish lirae. The aperture is oblique and subquadrate. The lip is simple. The columella is arcuate, denticulate at base, slightly calloused above, almost covering the umbilicus.

The size of the shell varies between 2 mm and 5 mm. The small shell is narrowly umbilicate, depressed, and stomatella-shaped. It is whitish, zigzagly striped with red, the stripes often broken into spots, white around the umbilicus. The spire is very short.

The inside of the lip is sulcate. The spiral platform descends into the deep and round umbilicus. It shows on its sides furrows of two spiral cords. The columella is set back far at its upper half and has several beads at its base.

The white shell attains a height of 2 mm, its diameter also 2 mm. It is a rather solid, shining shell with a narrow and deep umbilicus. The apex is obtuse. The spire is composed of four convex whorls, separated by a marked suture.

The round and deep umbilicus has a moderate size, showing some of the whorls. The circular aperture is slightly oblique. The peristome is continuous with a thin, sharp edge, appearing thickened within. It is attached to the body whorl only for a short distance.

It is round-ovate, angled above, dilated and subchannelled below. The columella is thickened, somewhat flattened and grooved below the narrow deeply perforating umbilicus. T The operculum is flat inside with 5 whorls. Its nucleus is situated one-third the distance across the face.

The body whorl is obtusely angular at the periphery. The base of the shell is nearly flat. The aperture is very oblique. The columella shows one or two teeth below, expanded above in a white callus, which half surrounds the narrow, deep circular umbilicus.

The aperture is rounded-quadrangular. The thin upper margin is curved and runs uninterruptedly in the basal margin. The columellar margin is partly reflected over the umbilicus. The interior of the aperture is nacreous, with a few shallow grooves, corresponding to the stronger external lirae.

The first whorls are smooth. The following whorls are spirally, delicately sulcate, with an elevated ridge in the middle. The body whorl is bicingulate, the cinguli elevated and distant. The convex base of the shell is concentrically lirate with the lirae larger around the umbilicus.

The columella is subvertical, slightly arched, with a slight swelling in the middle. The umbilicus is partly or completely covered by the columella expansion. The white umbilical tract is slightly impressed. Suter H. (1913-1915), Manual of New Zealand Mollusca; Wellington, N. Z. :J.

These are tumid below the sutures and sometimes obsoletely plicate there and spirally lirate. The body whorl is tumid at the periphery and convex beneath. The columella is slightly sinuous and prominent in the middle. The white umbilicus is funnel- shaped when open, frequently closed.

Epicephalites is a perisphictid ammonite, included in the subfamily Aulacostephaninae, from the Upper Jurassic of New Zealand and Mexico, related to Involuticeras. Its shell is involute, whorls inflated with a deep umbilicus. The outer half including the venter is ribbed, the inner half is smooth.

Some parents choose to omit cord severance entirely, a practice called "lotus birth" or umbilical nonseverance. The entire intact umbilical cord is allowed to dry and separates on its own (typically on the 3rd day after birth), falling off and leaving a healed umbilicus.

The shell of species in this genus is more or less transparent, subdepressed and contains an umbilicus. The aperture is semilunar and usually lacks teeth. The outer lip is thin and sharp. The animal is elongate and is able to retract completely within its shell.

The umbilicus is narrow.Species summary for Viviparus viviparus. AnimalBase, last modified 26 October 2013, accessed 4 June 2014. The animal can lock itself behind a round lid adorned with concentric striations (the operculum) , allowing it to protect itself-for several months if necessary - from dehydration.

The ribs on the periphery have open-fronted spines, the uppermost being the largest. The whole surface is covered with dense axial lamellae. The snail's aperture is circular and surrounded by a thickened varix. The umbilicus is deep and narrow, with strong axial lamellae within.

The suture patterns are slightly sinuous, though it can be more or less straight in some species. The umbilicus is small and barely noticeable, sometimes hidden altogether. The septa are averagely convex towards the tip. The siphuncle is small and circular in cross section.

The whole surface is covered with very fine oblique longitudinal striae. Spirals: there are very numerous fine, sharp, undulating scratches, which on the middle of the base are shallower and wider apart, but toward the umbilicus again become sharper and more crowded. Within the umbilicus are four or five somewhat beaded spirals, the first and strongest of which forms an umbilical carina. The color of the shell is faintly iridescent all over, creamy white, flecked with zigzag lines of crimson, which on the upper whorls are narrow and regular, on the penultimate whorl are remote, and on the last are irregular, broken and crowded.

The shell of this species is dextral (right-handed) in coiling. The shell of an adult snail is 16–27 mm in width. The umbilicus is narrow.Asia and the Pacific Islands - The World of Snails The color of the shell is brown, shading to white underneath.

The shell grows to a length of 60 mm. The extremely thin, white shell has globosely a conical shape with five (?) whorls. The umbilicus is reduced to a mere chink under the thin callus of the upper part of the columellar lip. The aperture is rounded rectangular.

The periostracum is irregularly striated, and densely covered with short (0.2-0.3 mm), curved hairs. These hairs usually remain in the umbilicus if worn away from the rest of the shell. Lost hairs leave pronounced scars. The animal is brownish grey with a darker anterior part.

Two in the vicinity of the suture are larger and. decorated with larger grainsThe body whorl is acutely angled at the base The shell surface appears smooth, but is encircled by many fine granulated spiral striae. The base is a little inflated. The umbilicus is absent.

Gastrioceratoidea is one of seventeen superfamilies in the suborder Goniatitina, ammonoid cephalopods from the Late Paleozoic. Shells are variable in form with a broad whorl section and wide umbilicus. Early whorls are commonly evolute. Shells may be smooth or sculptured with transverse striae (fine grooves) and constrictions.

The body whorl has a blunt angle at its base. This base contains 20 concentric lirae, and in the middle a deep pit or "false umbilicus". On the outside it is white, on the inside it is pearly. The thick, pearly columellar margin is S-shaped.

The peristome is continuous, although not free in consequence of the inner lip being attached to the shell. The outer lip is thin and sharp. The inner lip spreads on the lower part of the body whorl. The umbilicus is rather large, funnel-shaped, and deep.

The peristome is sharp and discontinuous. The outer and basal lip are convex, with a narrow opaque margin within, which is smooth. The oblique columella is straight, in adult specimens with a few inconspicuous plications above. The umbilicus is filled with callus, leaving only a slight pit.

The shell grows to a height of 1.1 mm. The small shell is depressedly and obliquely globose. It has a rough appearance and is unadorned in any way. It has a small, rounded, barely prominent apex, a large, round, very descending aperture and a small umbilicus.

It is narrowed above. The columella is slightly arcuate, and nearly vertical. The umbilicus is narrowly perforated, funnel-shaped, and smooth inside. On old shells the median carina becomes rounded on the last ¾ whorl, and there are numerous spiral riblets both above and below the slit fasciole.

The rest of the base, which is of a lighter tint than the dorsum, has scattered tiny white dots. The umbilicus is white. Over all is a transparent glaze, with a bronze reflex. There may be a faint gutter where the labrum joins the body whorl.

The umbilicus itself is decorated with a transversely-channelled sculpture. Its substance is margaritaceous. The interior of the round and simple aperture is pearly and smooth.J. Cosmo Melvill, Descriptions of eleven new species belonging to the genera Columbarium, Pisania, Minolia, Liotia and Solarium; Journal of Conchology v.

The deep umbilicus is subcircular and contains numerous slender plicae. The aperture is subcircular. The peristome is simple. This species is allied to Minolia singaporensis Pilsbry, 1889 but is larger and proportionately shorter, with three prominent keels on the body whorl and one bordering the umbilical cord.

The convex body whorl is rounded, quite abruptly and decidedly descending at the aperture. The rounded aperture is strongly, finely sulcate inside. The columella is straight, with a small projecting tooth at base. The umbilicus is deep, bounded by a strong white rib, about 1 mm. diameter.

The rounded aperture is smooth within. The columella is sinuous, arcuate, and dentate at the base. The umbilicus is moderate deep. This species is separated from all others in this genus by the scalariform spires, strongly plicate upper surface, and the deep channel encircling the periphery.

The wide aperture is oblique. The outer lip is acute, edged with alternate green and white, and smooth within. The white, thin columella is arcuate. It is wide, covering the place of the umbilicus with an ivory-white pad, which is closely appressecl to the body whorl.

The apertural margin is not thickened inside, the callus does not cover the umbilicus, the angularis is very weak, the parietal callus is weak or absent, no cervical callus is present. There is a minute translucent operculum. The surface is smooth, glossy, reddish to yellowish-brown.

The shells of the species in this genus are thin-walled and almost transparent. Because of this, they are iridescent. The outer lip is deflected. A flat callus of the inner lip covers completely or only in part the wide umbilicus (but only in fully grown species).

The umbilical fascia (or umbilicovesical fasciamedilexicon.com > umbilicovesical fascia Citing: Stedman's Medical Dictionary. Copyright 2006) is a thin fascial layer that extends between the medial umbilical ligamentsmondofacto.com > umbilicovesical fascia 05 Mar 2000 from the umbilicus, and extends inferiorly, becoming continuous with the visceral fascia enclosing the urinary bladder.

Ammonites belonging to this genus have small to medium-sized shells. Coiling is evolute, while whorl section is depressed, subtrapezoidal with oblique flanks and broad and low venter, maximum width is at shoulder. Umbilicus is wide and deep. Sharp, fibulate ribs are dense, tuberculate and spined.

The size of the plump, oval shell varies between 3 mm and 11 mm. The shell has five or six rounded, gently convex whorls with a smooth structure, the body whorl being the largest. The shell has a short, abrupt spire. There is no distinct umbilicus.

There is no umbilicus. The columella is short, straight, and ending in a slight knob inside the margin of the aperture. The aperture is crenulated by the sculpture, nacreous, obliquely set and subrectangular in form. The sutures are appressed, hardly visible except in the last three whorls.

The sutures are immersed; between the sutures the spire is angulated. The convex base of the shell shows somewhat granulate incremental lines. At the periphery the spiral rib is encircled with minute pink dots. The small umbilicus is deep and narrow and has a marginal callus.

They are spirally traversed by five very finely granulose lirae, the first two small, third larger, fourth small, fifth larger than the others. The suture is profoundly impressed and canaliculate. The body whorl contains 8 lirae on the base encircling the umbilicus. The columella is unequally bidentate.

The aperture is very oblique and rhomboidal. The outer lip is sharp, bevelled within and carrying a strong deep-seated tubercle. The parietal callus is coarsely wrinkled. The columella spirally ascends the umbilicus, terminating anteriorly in a massive bifid tooth, and higher up supporting a small tubercle.

The sutures are plain. Other distinctive features include a smooth, green columella, an open, black-ringed umbilicus. The columellar margin is thickened at the base of the shell, and has a very obtuse tubercle there. The rounded- quadrangular aperture is angular above and brilliantly nacreous inside.

Idoceras is a genus of perisphictacean ammonite, belonging to the Perisphinctidae subfamily Idoceratinae. The genus is known from the Upper Jurassic, with a widespread distribution. Shells of Idoceras are evolute, with a wide umbilicus; ribbing strong, bifurcate high on flanks. Suture simpler than in the similar Ataxioceras.

The shell of this species is thin and helicoid, with smooth and polished whorls. The inner lip is callous and indented, but the callus is not sufficiently large to cover or conceal the umbilicus. The peristome is produced into an angle, which ascends on the body whorl.

The umbilicus is narrow but open in juveniles, and closed in adults. The surface of the shell is semi-glossy, and it has from 4½ to 5½ whorls. The width of the shell is 18–25 mm. The height of the shell is 12–22 mm.

The small shell varies in thickness. It possesses two coarse, spiral keels (a spiral ridge usually marking a change of slope in the outline of the shell) that can vary in strength or even be obsolete. The shell has a wide perspective umbilicus, and a discontinuous peristome.

This sculpture is carried over the base but is absent from the walls of the wide umbilicus;. The rounded aperture is very oblique. Its margins are sharp, hardly meeting over the body except by a thin layer of enamel. The brown operculum is thin, and multispiral.W;H.

The spiral crenellae run round the sutures and round the callosity of the peristome. This is tongue-shaped and conceals almost the umbilicus. Melvill J.C. & Standen R. (1896) Notes on a collection of shells from Lifu and Uvea, Loyalty Islands, formed by the Rev. James and Mrs.

1 µm in diameter. This species is common in the oral and urogenital tracts of cercopithecine monkeys where it was first isolated in 1971. It was also isolated a human with an infected umbilicus and vagina in 1955. It has not been identified as a pathogen.

Philip Mairet). 'Symbolism of the Centre' in Images and Symbols. Princeton, 1991. p.52-54 In medieval times some Christians thought of Jerusalem as the center of the world (Latin: umbilicus mundi, Greek: Omphalos), and was so represented in the so- called T and O maps.

Their shells vary in size from small (7 mm in diameter, or about 0.3 inches) to medium (32 mm, about 1.3 inches), usually with a low, flattened spire, a very wide umbilicus, and usually with the upper lip margin (at the aperture) curving downwards or straightened.

The base of the shell is flat, spirally, subobsoletely lirate. The aperture subhorizontal. The outer lip is thin, margined with brown or corneous. The columella is subhorizontal, curved, toothed below the middle, receding above, not spreading around the umbilicus as in some other species of this genus.

There is a sculpture of dense spiral microscopic striae. The base of the shell is rounded. The umbilicus is narrow and deep, and it is surrounded by a callus funicle which expands anteriorly to join the simple lip in an angular lobe. The aperture is subcircular.

Shell colour is greenish or yellowish. The shell aperture has a mouth membrane which runs from the umbilicus along the inside of the outer lip. The animal is pale to dark grey or black, paler forms have large dark grey areas. The mantle lobe is very large.

The body whorl is obtusely biangular with about four low spiral cords above the upper angle, two and a very weak third between the angles. The base of the shell contains numerous spirals. The outer lip is thickened externally with a swelling or varix. The umbilicus is rather large.

The base is more equably curved, the spirals on it are stronger. The umbilicus is smaller, and is more strongly defined, not only by the stronger carina, but by the extracarinal furrow. The columellar tooth comes in higher up than in that species. Watson R. B. (1878–1883).

Moreover, the base is sculptured by irregular, radiating riblets and like the upper part, by microscopic striae. The funnel-shaped umbilicus is pervious, concentrically striated and plicated, and with two beaded spirals near the base. Its largest diameter is about 2/5 of the shell. The aperture is subcircular.

The shell is whitish or yellowish, with about 5 brown stripes, the upper two are usually weak. The lowermost stripe is quite near to the covered umbilicus. There is a slight variation of shell coulour within this species (see below). The animal itself is yellowish with grey tentacles.

The suture is rendered zigzag by the prominent compressed triangular recurved vaulted spines which arm the acutely carinated periphery. The whorls above and below contain numerous spiral series of granules. The wide umbilicus is deep, and coarsely obliquely striate within. The aperture is transversely oval, oblique, pearly within.

Falcitornoceratinae is one of three subfamilies of the Tornoceratidae family, a member of the Goniatitida order. Shells produced are extremely involute and have no umbilicus. Young and intermediate whorls have ventrolateral grooves. The adventitious lobe, which develops ontogenetically between the external, or ventral, and lateral lobes, is widely rounded.

The umbilicus is wide and shallow. The shell consists of three whorls. The last half-whorl comes scarcely in contact with the others, and is suddenly and deeply deflected. Sculpture: The body whorl is ringed by 16 thick, projecting, distant ribs which fade above and below at the sutures.

The umbilicus is also rarely seen in other species. Juveniles of Eobania vermiculata have a considerably larger apex. The width of the shell is 12–25 mm, but in Greece the adult shells are usually below 15 mm in width. The height of the shell is 9–20 mm.

Sutures on the umbilical side are radial and deeply incised. The test wall is calcareous, coarsely perforate on the spiral side, but imperforate adjacent to the sutures. The umbilical side is imperforate and smooth. The aperture is an interiomarginal arch, outside the umbilicus, extending nearly to the periphery.

The periphery of the body whorl is angulated. The base of the shell is short, well rounded, and lacks an umbilicus. It is marked by the continuation of the axial ribs and incised spiral lines which equal those on the spire in strength. The aperture is pear-shaped.

The shell has a more or less distinct peripheral angle, visible also at the base of the upper whorls. The sculpture has slight, microscopical, close-set spiral striae and prosocline growthlines. The umbilicus is lacking, although there is sometimes a small chink. The aperture has a straight columellar border.

Shape convex to low-convex above, flattened below. Whorls rounded, with shallow to very shallow sutures. Umbilicus moderately wide, symmetrical, deep, exposing upper whorls, usually slightly overlapped by reflected peristome. Mouth broadly oval, except where interrupted by penultimate whorl; last part of body whorl expanding, descending near mouth.

The apex is strongly convex with 3.5-4.5 convex and regularly increasing whorls. The last whorl is not inflated near the aperture and not descending. The aperture is slightly oblique and the umbilicus is wide. The animal is bluish grey with a lighter sole and bluish black upper tentacles.

From the center of this circle, the circuit of the city wall was designated and plowed. Everything within this area was sacred. It was the traditional center of the city as a similar area was in the original Palatine settlement. The Umbilicus urbis Romae marks the center of Rome.

One reported specimen from New South Wales had 41.1 mm of height and 54.1 mm of diameter. The shell is moderately elevated. The umbilicus is closed in adults, but narrowly open in juveniles. A row of foreign objects is very prominent, obscuring more than half of the dorsal surface.

The aperture is clearly visible and large. The color inside the aperture is white or light yellowish. There is a lip inside the aperture which is white in color. The umbilicus is initially narrow, but at the last whorl it increases to one-fourth of the shell diameter.

The oblique columella is strongly plicate above, its edge nearly smooth and shows blunt teeth. The large aperture is subrhomboidal, lirate within, and grooved. The basal lip thickened and crenate The umbilicus is wide and deep. The umbilical tract is funnel-shaped, rather broad, with a central rib.

The very small, solid shell is perforate or has a narrow umbilicus. It contains a few convex whorls. The protoconch consists of one or two smooth whorls. The turbinate or globoso-conic shell shows numerous subequal spiral cords with in their intervals well developed or weak cross threads.

The size of the shell varies between 8 mm and 15 mm. The white, sublenticular shell is flattened convex above, more convex below. It contains oblique radiating riblets, interrupted by an obtuse peripheral rib The interstices of the riblets are finely spirally striated. The umbilicus has a moderate size.

The others are slightly nearer the axis. Between these, nearly square deep reticulations are formed by the radiating ridges before described. Beside these there are three faint spirals on the upper and three on the basal surface, nodulated at their intersections with the radii. There is an ample umbilicus.

There is no umbilicus or callus. The columella is not grooved or thickened. The aperture is oblique and proportionately less wide than in Calliostoma apicinum to which the whole shell bears a strong superficial resemblance.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, PhiladelphiaDall, W. H. 1881.

The shell has four or four and a half slightly convex whorls. The last whorl is often weakly descending near aperture. The whorls from whorl 3 onwards are more narrowly coiled than in Oxychilus cellarius, the last whorl descending lower. The umbilicus is wide (one sixth of diameter).

The size of the shell varies between 4 mm and 5.5 mm. The small, solid, thick shell has a globose-conic shape, evenly grained all over. it is blackish or pink varied with darker. It is imperforate when adult, and has a groove at the place of the umbilicus.

Because of the high rejection rate, sometimes it would take an entire day just to complete one or two photographs. Subject ages ranged from three to ninety-six years of age. In addition to the Japanese majority of navels photographed for UMBILICUS, a percentage of outsiders were also included.

The base of the shell is a trifle convex, the middle portion concave toward the umbilicus. The tetragonal aperture is very oblique and almost horizontal. The upper lip is straight, bearing a strong tubercular tooth midway. The outer and basal lips are well rounded, thickened and plicate- denticulate within.

The seven whorls are flattened, the upper ones finely spirally striate and sometimes very obsoletely plicate. The remainder is smooth, obliquely finely striate. The base of the shell is flattened, slightly convex, obliquely streaked, concave and white around the umbilicus. The body whorl is bluntly angled at the periphery.

The whorls are plane, but the penultimate whorl is angulate. The margin of the umbilicus is simple. The top of the columella is uniplicate and below it has three small tubercles.H. Pilsbry, Manual of Conchology XI, Academy of Natural Sciences, PhiladelphiaThe Journal of the Bombay Natural History Society v.

The outer lip is continuous with the columella, which is raised, arched in harmony with the lip, but not reflected. There is no umbilicus. The simple lip is hardly thickened. There is a little callus on the body and in the posterior angle between the lip and body;.

The outer lip is strengthened by an inner white callosity. The concave columella is vertical. The inner lip is broadly expanded, covering the umbilicus, and spreading as a broad white callosity over the parietal wall. Suter H. (1913-1915), Manual of New Zealand Mollusca; Wellington, N. Z. :J.

Their sculpture contains 7 to 8 spiral striae and incremental lines. The body whorl is obtusely angular at the periphery, rather convex beneath, slightly impressed in the region of the umbilicus. The lightly grooved aperture is subcircular-quadrate and iridescent within. The lip is within a trifle thickened.

The thick outer lip is lirate inside. The short columella is, straightened, and obtusely subtuberculate in the middle, ending in a projecting tooth, between which and the basal margin there is a deep narrow notch. The umbilicus is narrow. The ground color varies from nearly white to ashen-pink.

The aperture has a characteristic shape. The lip is reflected and forms a "U" shape when seen from above. The umbilicus is deep and covers 1/7 of the shell diameter. The width of the shell is 6–8 mm; the height of the shell is 3–4 mm.

The base of the shell is short, well rounded, and broadly umbilicated. It is marked by seven broad low bands which grow successively wider from the umbilical edge toward the periphery. These bands appear as a series of turns of a bandage. The umbilicus lacks any spiral sculpture.

Moreover the whole base is covered with microscopic radiating striae, beautifully waved in an S-like manner. The umbilicus is moderately wide, pervious, and funnel- shaped. Its wall is wave-striated, with a shallow spiral groove terminated by a tooth on the columella. The aperture is irregularly subquadrate.

Garantiana is strongly ribbed and generally evolute. The inner whorls are exposed in a wide and fairly deep umbilicus. Ribs arise at the umbilical margin and split in two (bifurcate) about midway up the sides and cross over the outer (ventral) rim. Garantiana was named by d'Orbigny, 1845.

A heavy outstanding varix occurs a short distance behind the aperture. The small size, produced base, and wide umbilicus are characters which distinguish this from other Australian members of the genus.Hedley Charles (1902) Studies on Australian Mollusca. Part VI; Proceedings of the Linnean Society of New South Wales vol.

The base is nearly straight. The arched columella is deeply excavated at the position of the umbilicus. The whole umbilical area is brilliant vermilion, with a black spiral rib. The oval operculum is black to yellowish inside, with a marginal apex, frequently concealed by growth of the last whorl.

The plant is found in southern and western Europe, often growing on shady walls or in damp rock crevices that are sparse in other plant growth (thus, "wall" pennywort), where its succulent leaves develop in rosettes. It is not at present under threat.Lockton, A.J. (2009-12-05). "Umbilicus rupestris".

The shell is moderately umbilicated, conoid, solid, light rufous above, paler below, especially towards the umbilicus. Nepionic whorls are finely granulated, the remainder closely covered with fine curved riblets, and densely infested with granules arranged in quincunx above, but somewhat irregularly below. The spire is pyramidal. Apex is acute.

The origin of the Prolecanitida may be found in the Prolobitidae which was originally included in the Anarcestida but recently removed to the Goniatitida. Following their inception, the Prolecanitida divided into two lineages, identified by superfamilies; the earlier U Dev – M Perm Prolecanitoidea in which the shells are fairly smooth and characteristically have a large umbilicus and the later U Miss-Trias Medlicottioidea in which the umbilicus is small and there is moderate sculpture along the flanks. The Prolecanitoidea, through the derived family Daraelitidae is the source for the Ceratitida, beginning with the Xenodiscidae. Prolecanitids showed long-term, gradual changes in shell geometry and the most limited use of available forms (euphemistically morphospace) as compared to the dominant goniatitids.

In a normal umbilical stump, you first see the umbilicus lose its characteristic bluish-white, moist appearance and become dry and black After several days to weeks, the stump should fall off and leave a pink fleshy wound which continues to heal as it becomes a normal umbilicus. For an infected umbilical stump, diagnosis is usually made by the clinical appearance of the umbilical cord stump and the findings on history and physical examination. There may be some confusion, however, if a well- appearing neonate simply has some redness around the umbilical stump. In fact, a mild degree is common, as is some bleeding at the stump site with detachment of the umbilical cord.

The columella is oblique, nearly straight, ending below in a prominent, obliquely furrowed but not bifid tooth, with a large tubercle at the junction of its upper and middle third, and with a flange throughout its whole length bent towards the umbilicus. The umbilicus is wide and deep, with a funicle winding up its outer side to the tubercle on the columella. The umbilical border overhangs, and has 6 medium-sized tubercles, and is margined by a flat, axially incised, spiral lira, with a threadlet on either side. The colour of the shell is light ashen-grey, with obscure flames of deeper grey or buff, and with numerous small pink dots on the second and third whorls.

This part is embedded within the skin follicle and has an opening at the base (proximal umbilicus) and a small opening on the side (distal umbilicus). Hatchling birds of some species have a special kind of natal down feathers (neossoptiles) which are pushed out when the normal feathers (teleoptiles) emerge. Flight feathers are stiffened so as to work against the air in the downstroke but yield in other directions. It has been observed that the orientation pattern of β-keratin fibers in the feathers of flying birds differs from that in flightless birds: the fibers are better aligned along the shaft axis direction towards the tip, and the lateral walls of rachis region show structure of crossed fibers.

The height of the shell attains 5.2 mm, its diameter 5.6 mm. The solid shell has a depressed conoidal shape. It has a false umbilicus. The small protoconch contains 1½ flattened turns, smooth at the origin, and gradually developing four spiral lirae which become granulose cinguli on the adult whorls.

Those on the upper spiral are rather the larger. The middle of the whorl for about 0.25 cm is bare. On the base there are five closely beaded threads, of which the inmost and strongest defines the umbilicus. Between the outermost and the carina is a broad slightly sunken furrow.

The shell grows to a length of 7.6 mm. The high shell has a broadly conical shape. The color of the shell is pure white when weathered, but apparently slightly brownish when fresh, with a pearly nacre below the thin calcareous surface layer. The shell has a very large umbilicus.

Umbilicus schmidtii is an unbranched erect perennial herb up to 25 cm high, glabrous in all parts. Basal leaves orbicular, peltate, up to 6 cm in diameter, somewhat succulent, margin slightly crenate to almost entire, petioles long. Cauline leaves smaller, shortly petiolated to almost sessile. Inflorescence long many flowered terminal raceme.

The size of the shell of species in this genus is small to moderate. The iridescent shell is thin and contains a conspicuous umbilicus. Its sculpture shows spiral rows with many tubercles. The shells resemble Solariella, but differ in the radula, which is longer, with a larger number of uncini.

The outer lip is slightly crenulated and contains six lirae (fine linear elevations of shelly material). The columella is abaxially inclined and shows three folds with the siphonal fold displaying a noticeable tooth. The shell lacks an umbilicus. The periostracum is covered with very short hairs along the spiral lines.

Pachyceras is a genus of perisphinctoid ammonites from the Middle Jurassic, upper Callovian stage, and is the type genus for the family Pachyceratidae. The shell is involute, subglobular, with a deep umbilicus and flattened flanks that slope toward a more narrowly rounded venter, and covered by low, widely spaced ribs.

On the top of each whorl these ribs disappear into the flat sutural zone between the whorls. The aperture is ovoid with the outer lip lacking striae. The columella is strongly inclined abaxially showing two folds, with the rim of the siphonal canal forming the third fold. There is no umbilicus.

GONIAT) also include Lyrogoniatites in the Cravenoceratidae but in the Cravenoceratinae. The older Treatise (Miller, Furnish, and Schindiwold 1957) puts Lyrogoniatites along with Neoglyphioceras in the Goniatitidae and subfamily Neoglyphioceratinae, differentiating the two on the basis of the umbilicus—that of Lyrogoniatites being moderately large, that of Neoglyphioceras being narrow.

Ba is characterized by having a high spire and an umbilicus which is either completely closed or slightly laterally cracked. There are only 3⅛–3½ whorls, and its apical sculpture consists of about a dozen spiral cords. There are no barriers to its aperture. ' has a shell with a diameter of .

The shells of the Strigoceratidae are compressed to oxyconic, with a narrow or minute umbilicus and simple or irregularly branched ribbing almost confined to the outer (ventral) half of the whorl sides. The sutures are moderately simple to complex, with a long umbilical lobe bearing a graded series of Auxiliaries.

The anterior is more or less undulated. On the base are a single cord, a wide interval, then three more adjacent smaller plain cords, the three close-set beaded cords at the verge, of the small perforate umbilicus. The aperture is circular. The upper lip is produced on the body.

The median portion is encircled by three prominent keels, the upper two visible on the spire. The oblique striae of increment are scarcely visible. The base of the shell contains a few coarse but not deep spiral sulci, carinated around the funnel-shaped umbilicus. The aperture is subcircular, iridescent within.

The base of the shell contains 7 concentric cinguli, tessellated red and white. The shell is rosy, sometimes olivaceous, ornamented with darker maculations on the body whorl, the cinguli tessellated. The suture is nearly filled by the first granose ridge. The wide umbilicus is profound, finely striate, and lightly cingulate.

The oblique aperture is subtetragonal. The outer lip is plicate within, dentate above, the tooth usually bifid. The basal margin is curved and crenulate within. The columella is inserted deep in the rather narrow umbilicus, bearing a strong dentiform fold above and a large quadrangular biplicate tooth at the base.

The three rows around the umbilicus are not so highly developed. The aperture is round. The horny operculum is multispiral.Melvill c& Standen (1903), Descriptions of 68 new gastropoda from the Red Sea, the Gulf of Oman and the Northern Arabian Sea; The Annals and magazine of natural history 7th ser. v.

The teleoconch contains 2½ convex whorls. It is clathrate by about 15 equidistant radiating and 7 spiral ribs, with deep pitted interspaces. The sculpture terminates with a spiral ridge surrounding the rather wide, deep umbilicus. The circular aperture is frequently slightly sloping and is slightly attached to the parietal wall.

Close, regular and fine, raised spiral lines cover the whole shell, crossing the ribs and interstices alike. These are in their turn overridden by transverse microscopic threads. The base of the shell is excavate in the centre. The umbilicus measures one-fifth of the shell's diameter, exhibiting the previous whorls.

The body whorl has a depressed rotund shape. On top it shows an angle, below it is rotund. The body whorl contains seven lirae, the upper ones granulated, the others plane. The shell has a wide and deep umbilicus.. It contains seven ridges above the periphery, the upper ridges being beaded.

The size of the shell attains 8 mm. The shell has a trochiform shape with a broad base, more conical and less scalar, with a large open umbilicus and brilliant color. Sculpture: the shell is gathered into small regular flat puckers below the suture. These are weaker on the body whorl.

The height of the shell varies between 13 mm and 23 mm. The solid, conical shell is imperforate. It has seven, inflated globose whorls with a rounded periphery and a closed umbilicus. The whorls show a more or less obvious angle or carina in the middle of the upper surface.

The height of the shell attains 9 mm, its diameter 15 mm. The depressed, pale reddish or fawn shell is perforated with a round umbilicus up to the apex. It is faintly spirally lirate and angulated almost above the suture. It is rounded-angular at the middle of the keel.

The acute outer lip is thin, pearly and iridescent, and, apparently lirate within. The columella is extremely oblique. Its inner edge is concave, distinctly toothed or hooked below, bearing a shallow groove parallel with the edge, from the place of the umbilicus downward. The white columellar area is very wide.

The height of the shell attains 19 mm, its diameter 21 mm. The thick shell has a very deep umbilicus, nearly reaching to the apex. It is a little shining, yellowish, with elongated flexuous unequal brownish- green spots and dots of the same color. The acute spire is little elevated.

The broadly umbilicated shell has an elevated-conical shape. It is cinereus, painted with brown undulating lines. The whorls are ornamented with transverse riblets, the last with 3 median lirae, longitudinally elevated striate. The large umbilicus is encircled by a crenulated cingulus, and within elegantly decussated by radiating and transverse lines.

The apertural margin is white and weakly reflected. The umbilicus is small, 2.34~3.24 mm (mean 2.63 mm), and partly covered by the dilated columellar margin. The width of the shell is 21.68-25.74 mm (mean 23.82 mm). The height of the shell is 14.58-16.62 mm (mean 15.80 mm).

Tainonautilus is an extinct coiled cephalopod that lived during the Permian and Early Triassic which is included in the nautiloid family Tainoceratidae. Tainonautilus has an evolute shell with a subquadrate whorl section. Flanks and outer rim (venter) are flat. The umbilicus is wide and deep; umbilical shoulders have a prominent keel.

The Gastrioceras shell, or conch, is subdiscoidal to subglobose in form with moderate to wide umbilicus. Ornament varies according to species, varying from simple transverse lirae to reticulate produced by the addition of faint longitudinal lirae. The umbilical shoulder is nodose, nodes elongated transversely. Some species have rather strong ribs.

The body whorl has a protruded, keeled periphery, not descending more rapidly, with a distinct subperipheral sulcus. The umbilicus is widely open and U-shaped. The last whorl does not decoil as rapidly. The apertural barriers consist of three parietals, a single columellar one that slants downwards, and three long palatals.

The base of the shell is moderately convex, with a deep funicular umbilicus. It is closely finely spirally threaded, the threads a little coarser near the umbilical margin. In the interspaces between the keels on the spire are very minute close spiral striae. The aperture shows a very shallow sulcus.

The convex base often has an eroded area in front of the aperture, above a closed umbilicus, the area around which is usually white. The oblique aperture is nearly round. The outer lip is black-edged, smooth and pearly within. The columella is short, arcuate, and strongly bidentate near the base.

Vartoukian, S.R., Palmer, R.M., and Wade, W.G. (2007). The division "Synergistes". Anaerobe. 13, 99–106. Due to their presence at illness related sites, the Synergistetes are suggested to be opportunistic pathogens but they can also be found in healthy individuals in the microbiome of the umbilicus and in normal vaginal flora.

The surface is dull, with fine incremental lines crossed by extremely fine spiral striae. The base is well rounded with a deep, not funicular umbilicus. The simple aperture is rounded. The outer lip produced at the suture and united with the columella by a thin glaze of enamel over the body.

The aperture is semioval. Its sculpture is perfectly smooth but for some curved puckerings which radiate from the umbilicus, but very soon die out. Above the middle the body whorl is roundly angulated. The color of the shell is pure white, with a transparent calcareous layer over brilliant fiery pearly nacre.

The shell is openly umbilicate (the umbilicus about one-fourth the total diameter), of a uniform pale brown tint, discoidal. The spire is convex but low. Suture is deeply impressed. The shell has 3 ½ whorls, that are convex, slowly increasing, the embryonic 1 ½ densely striate spirally, the rest radially costellate.

Apertural margin is thickened except on upper side, and with a wavy contour seen from the side. Umbilicus is open but very narrow, only partly covered by columellar margin of the aperture. The width of the shell is 2.5–2.6 mm. The height of the shell is 5.4–6.1 mm.

The thick outer lip is lirate within. The columella is less deeply sinuous than in T. quadricostata, arcuate, tridentate below. The umbilicus is narrower than that of T. quadricostata. The color of the shell is whitish, radiately striped above with pink, the ribs of the base dotted or articulated with pink.

The size of the shell attains 2.2 mm. The shell is narrowly umbilicated, faintly striate, with a few indistinct spiral lines below the suture, and numerous well defined ones on the base. Around the umbilicus the inferior striae become stronger. The surface of the shell is smooth and greyish white.

This rite is blocked and stopped by the monkeys. These incidents are absent in Valmiki Ramayana. # Rama cuts down the heads of Ravana repeatedly, but could not kill him. Vibhishana informs Rama that Ravana has got amrita deposited in his umbilicus and that until it is removed he cannot be killed.

Paraphaeosphaeria michotii has a rather similar morphology to P. pilleata, but can be distinguished microscopically by the lack of both an umbilicus and an evanescent cap on the tips of the asci. Additionally, P. michotti has narrower ascomata (up to 250 μm wide), a thinner peridium (16 μm), and branched pseudoparaphyses.

The eight whorls increase regularly in size. They are a little rounded, angulated at the carina, rather tumid on the base, and have a wide umbilicus. The suture is angulated and well defined, but a little filled up by the carina of the overlying whorl. The aperture is (apparently) perpendicular and semioval.

The shell of Ophiceras evolute, whorls all showing, slowly increasing in height, and slightly embracing the previous. Umbilicus, wide and moderately deep. Surface ornamented with faint folds, which in some develop into coarse ribs in the mature growth stage, and transverse striae. Suture is ceratitic, lobes and saddles usually long and narrow.

Asymptoceras is a genus of aipoceratids (Nautiloidea) similar to Aipoceras but tightly coiled and with only part of the body chamber divergent from the previous whorl. Shell evolute, expanding fairly rapidly; umbilicus open, perforate; whorl section ovoid to subquadrate. Asymptoceras is known from Mississippian (Lower Carboniferous) sediments in Europe and North America.

An acquired umbilical hernia directly results from increased intra-abdominal pressure caused by obesity, heavy lifting, a long history of coughing, or multiple pregnancies. Another type of acquired umbilical hernias are incisional hernias, which are hernia developing in a scar following abdominal surgery, e.g. after insertion of laparoscopy trocars through the umbilicus.

Sutures are depressed and curved to nearly radial. The umbilical region is covered by triangular flaps that extend from the umbilical margin of each chamber, forming a small chamberlet beneath. The aperture is a low, interiomarginal arch, outside the umbilicus. The classification here is that of 1964, in the Treatise on Invertebrate Paleontology.

Strongly convex to pyramidal above, rounded below, with 4.7–5.2 whorls. Whorls rounded, flattened above near the moderately deep sutures. Umbilicus narrow to very narrow, deep, ± symmetrical, partly overlapped by reflected peristome. Mouth almost round, except where interrupted by penultimate whorl, the last part of body whorl expanding markedly, descending slightly near mouth.

The body whorl is ventricose, radiately costellate above, with three acute elevated median spiral cinguli, beneath with obsolete concentric striae. The umbilicus is wide, carinated at the periphery, plicate, and denticulate. The aperture is subcircular. This marine species is finely and closely reticulated ; the whorls are rounded and show no trace of angularity.

The body whorl is subangular at the periphery and around the umbilicus. The latter is funnel- shaped, one-fourth the total diameter of the shell, white within and with distinct growth lines. The oblique aperture is roundly subquadrate. The columella is slightly dilated above, straight in the middle, and bluntly angular at base.

The body whorl is subcylindrical, obtusely subangular at the periphery, convex beneath. The surface all over is encircled by delicate spiral elevated striae, and around the umbilicus decussated by growth lines. The aperture is subcircular, a trifle modified by the contact of the penultimate whorl. The margins are all thin and simple.

The size of the shell varies between 23 mm and 37 mm. The pale beige, discoid shell has a weak but marked spiral sculpture. But the first two whorls of the teleoconch have a purple color. The open umbilicus is only sealed for about 75% by the callus of the inner lip.

Sometimes (as in a cotype) only 1 (midwhorl) lira on 2nd and 3rd whorls, but the peripheral one comes into view on 4th whorl. On the base of the shell there is usually a marginal lira and 7-8 weaker lirae, variable. The umbilicus is not completely closed in the largest shells.

The base of the shell is convex, generally a little more coarsely lirate than the upper surface. The aperture is subquadrangular, oblique, and not angled at the junction of basal lip and columella. The columella is perceptibly arcuate. The large, white umbilicus is funnel-shaped and margined by one or several spiral riblets.

The compact shell of species in this genus has an orbicular-conoidal shape and is porcellanous and polished. The subquadrate aperture is longer than wide, The inner lip is straight, forming an angle with the outer lip. The umbilicus is open (not covered by a callous deposit) and perspective. The margin is crenulated.

One or two above the periphery are stronger than the rest. The lowest of all is much the strongest and define sthe umbilicus, within which the whole sculpture increases in distinctness. On the penultumate whorl there are about 12 spirals fully stronger than on the last. The furrows are broader than the threads.

The uppermost of the keels on the body whorl revolves up to the spire and forms the angle on the upper volutions. The lowermost carina borders the umbilicus and the next one occupies the middle of the under surface. The longitudinal lamellae are continuous on and between the keels. The aperture is round.

The shell has 5½ slightly convex whorls. The last whorl is a little descending and then slightly ascending in front, distinctly constricted behind the peristome. The base of the shell is perforated by a deep and conspicuous, though not wide, umbilicus. The shell aperture is ovate, and is a fleshy-brown color inside.

Columella callus thin, with underlying ribbing showing through; umbilicus closed. Colour white with major spiral ribs yellowish to reddish brown. Size: Up to 76 mm in length. Distribution: Atlantic, Mediterranean and Indo-West Pacific Oceans; in Australia, known only from Port Stephens to Ulladulla, NSW, at depths of 412–1829 metres. Rare.

The size of the shell varies between 5 mm and 13 mm. The solid, umbilicate shell has a conical shape. It is deep green, brown, pinkish or olivaceous, more or less dotted with white and a self-color, sometimes radiately flammulated with white. A tract around the umbilicus is white, tessellated with brown.

The inner walls of the umbilicus show strong revolving lines delicately reticulated by the lines of growth. The whorls are rounded, with no carina at the periphery. The thin columella is arched, not reflected. The aperture is nearly round, but angulated above by the sutural thread, and below by the umbilical keel.

Cinysca dunkeri (Lüderitz-eastern Wild Coast) has a thick, rounded shell; uniformly pale on the west coast, speckled on the south coast. Umbilicus large and obvious. About eight strong, equal- sized ridges spiral around each whorl and corrugate the outer lip. Operculum horny and flexible, but has spiral rows of minute calcareous beads.

The height of the shell varies between 12 mm and 40 mm. The sides of the shell are flat, giving it a triangular profile. The whorls are heavily sculptured with strongly beaded spiral cords along the periphery and the subsutural region with weakly beaded spiral cords in between. The umbilicus is closed.

The umbilicus is rather large and deep. Its color is yellowish-brown, frequently banded with a darker tint. The fronds are usually dark brown or blackish. The white, almost round aperture has a rather long, open posterior siphonal canal that gradually widens, but is narrow and turns to the right at the beginning.

The outer lip is iridescent and plicate within. The basal margin is rounded and denticulate. The oblique columella is nearly straight, slightly folded above and bidentate at its base. The umbilicus has (in fully adult specimens) a crenate marginal rib, white within, and perforating scarcely deeper than the insertion of the columella.

The shell of Branneroceras is typically marrow, evolute, with a wide or moderately wide umbilicus. Coiling maybe slightly irregular. The surface has a crenulate appearance produced by biconvex growth lines crossed by fine longitudinal, wirelike, lirae. Ribs extend Laterally from the umbilical shoulder onto the lateral flanks and persist to full maturity.

The periphery of the body whorl is subangulated, marked by a slender spiral cord. by six, narrow, flattened, spiral bands and between these and the umbilical chink by seven additional bands of about double the width of the former. The umbilicus covered with a white callus. The aperture is subcircular and very oblique.

The perviois umbilicus is funnel-shaped. Its largest diameter occupies nearly ¼ of that of the base. Its margin is bordered by a strongly beaded rib, which can be followed still a little in its interior, which is otherwise rather smooth, though sculptured by very fine radiating and spiral striae. The aperture is rhombic.

Where they cross, they form small tubercles. The body whorl is angular at the periphery. The flat base of the shell is sculptured by 12 spiral lirae and by radiating riblets, which make the inner 9 lirae beaded, the outer ones being crenulated. The small umbilicus is funnel-shaped, pervious, with smooth walls.

The sulcus at the aperture next the body is shallow. The outer lip beyond it is moderately produced and crenulate by the sculpture. The thin and arcuate columella has a very small notch at its base. There is a deep twisted perforate umbilicus and a thin layer of enamel on the body.

The three whorls are loosely coiled. The body whorl contains 16 thick, prominent ribs that cross the whorl, slender on leaving the suture. They slant forward, thickening rapidly, but when turning they descend the periphery perpendicularly. On the base they bend and then taper and rapidly curve into the umbilicus, crenelating its margin.

The umbilicus is very small and contracted, not so much by the reflection of the inner lip as by the columella being bent round to the right across it. The yellow, horny operculum is very thin with about 11 very faintly defined turns. Watson, R. B. 1879. Mollusca of H.M.S. 'Challenger' Expedition.

The height of the shell is 7.5 mm, its diameter 8.8 mm. The five whorls of the yellowish-white, umbilicated shell increase rapidly in size. They are flattened at the suture and then moderately curved. Only the body whorl is more curved and slightly wrinkled at the base and the funnel- shaped umbilicus.

The shell of Gymnites is evolute, generally smooth, with a wide umbilicus. Whorls are moderately embracing, whorl section oval and somewhat compressed. The outer whorl may be costate or have rows of nodes, or both. The suture is ammonitic with a wide bifurcated ventral lobe and two lateral lobes on either side.

The columellar and palatal- basal lip are narrowly reflected. The umbilicus is closed, and the umbilical depression is deep. The teleoconch possess irregular axial striae or blunt growth lines, which are often crossed by a spiral element. In a small area immediately behind the palatal-basal lip some axial ribbing were observed.

Genera of the Uddenitinae have narrow discoidal shells with narrow flat or sometimes grooved venters. Sutures are goniatitic to ceratitic with rounded saddles and slightly pointed to digitate lobes which form a declining series going toward the umbilicus. The ventral lobe is commonly long and narrow, and trifucated with sharp, simple prongs.

The body whorl is obtusely angular. Each whorl is encircled by four sharply-compressed well- elevated ribs, the two uppermost of which are beaded. The interspaces are concave, smooth, with a single groove near the margin of the umbilicus. The latter occupies ⅓ of the base, is tunnel-shaped and penetrates to the apex.

Shells of juveniles and young adults of this snail are typically covered with hairs 1mm in length. The hair may be absent in older specimens. The dark-brown shell is characterized by a flat upper side with a very slightly sunken spire and a wide umbilicus. The peristome is flattened above and below.

The shell is widely umbilicated, the umbilicus is carinated, the area between the carination and keel concave. The shell is a uniform cream colour, slightly tinted with brown. The operculum is concentric, of uniform thickness, concave and shelly on the exterior, which is faintly granular. It is horny on its inner face.

Uralopronorites is a genus of very involute and smooth, medium-sized, prolecanitids with a distinct furrow along the venter and closed umbilicus. The adult suture has 22 lobes in all, 18 of which, nine on either side, are umbilical. Uralopronorites comes from the Upper Carboniferous (Pennsylvanian equivalent) of Kazakhstan. It is an ammonite.

The base of the shell is nearly flat, but slightly convex. The umbilicus is funnel-shaped, rather large, pervious, its wall with raised, concentric and radiating striae, more or less beade. The aperture is rounded- quadrangular, with angles at the ends of the keels, especially of the umbilical one. The margin is sharp.

The shell is discoidal and very involute, with rapidly expanding and compressed whorls, fine radial ribs, a rounded venter with a shallow furrow, and almost closed umbilicus.

Moreover, the whole body whorl is covered with irregular radiating wrinkles or riblets, instead of the regular ribs on the upper whorls. These ribs are especially conspicuous and more regular on the base, except towards the periphery where they form thinner, irregular wrinkles. The umbilicus is pervious, funnel-shaped. Its walls has strong wrinkles.

Umbilicus comprises 18 species of annual and perennial herbs with a characteristic foliage. The genus is distributed from the mid-Atlantic archipelagos, W Europe, the Mediterranean to Iran. It also occurs in some African mountains. In the Cape Verde Islands, the genus is represented by a single species described as endemic to the archipelago.

Meekoceras is characterized by a compressed, discoidal, evolute or involute shell with flattened sides and narrow, flattened or rounded venter that is without keels or furrows. The surface is smooth or with lateral folds, but no tubercles, spines, or spiral ridges. Umbilicus variable, body chamber short. Sutures ceratitic with smooth rounded saddles and serrated lobes.

Posttornoceras, type genus of the Posttornoceratinae was named by Wedekind in 1910. Posttornocerashas a subglobular to discoidal shell with a small, closed umbilicus and biconvex growth lines (Miller et al. 1964). Sutural lobes next to the ventral lobe are formed adventitiously in the first latera saddles. Posttornoceras is derived from Exotornoceras (Saunders et al.

The peristome is simple, continuous, slightly attached to the body whorl, and reflected over the umbilicus. The operculum of the type species is thin, roundly ovate. it has a delicate horn color, of few abruptly enlarging whorls indistinctly defined by a spiral thread and showing sinuous transverse lines of growth. The nucleus is slightly excentric.

Polyptichites is the perisphictacean ammonite genus from the Lower Cretaceous of Russia. The shell is subinvolute and coarsely ribbed; ribs bifurcate or trifurcate mid or low on the flanks and cross over the rounded venter. The umbilicus is relatively small and deep. Outer whorls partially envelop the previous leaving a fairly deeply impressed dorsum.

An appendix with some early inflammation may give a non-specific irritation somewhere near the umbilicus (belly button). Should the inflammation become severe, it may actually irritate the inner lining of the abdominal cavity called the peritoneum. This thin layer of tissue lies deep to the abdominal wall muscles. Now the pain has become "localized".

Darvasiceras was a prolecanitid ammonoid cephalopod from the Early or Lower Permian Chelamchin Formation of Tajikistan. The genus is included in what is now the superfamily Medlicottioidea. The type species is Darvisciceras minum. The shell of Darvasiceras is discoidal, moderately involute in adult stages; the venter narrow, smooth, and flat; the umbilicus shallow and small.

The outer lip is thin. There is no umbilicus. The columellar tooth is weak and is deeply seated inside the pyriform aperture. J.J. van Aartsen, E. Gittenberger & J. Goud, Pyramidellidae (Mollusca, Gastropoda, Heterobranchia) collected during the Dutch CANCAP and MAURITANIA expeditions in the south-eastern part of the North Atlantic Ocean (part 1); CANCAP-project .

The oblique aperture is roundly elliptical. The outer lip is simple and bevelled inside. A short thin glaze can be found on the base of the whorl. The arcuate columella is everted posteriorly, with a tiny notch where it joins the round basal lip at the end of the bordering lira of the umbilicus.

The body whorl is encircled by ten strong keels whose interstices are occupied by small and smaller threads as before. The apex is elevated and consists of two small and glossy whorls. The umbilicus is wide and deep, penetrated by five elevated spiral ridges beaded by longitudinal sculpture. The aperture is circular, slightly oblique.

For terms see gastropod shell The shell is colourless or weakly brown and weakly shiny. The microsculpture (only visible under a microscope, 35-40 x) is faint, spiral lines crossing irregular radial lines. There are 3.5-4 convex whorls, the last whorl increasing and not descending near aperture. The umbilicus is wide and slightly excentric.

The size of the discoid shell varies between 24 mm and 30 mm. The teleoconch consists of 4.5 weakly convex whorls. This species differs from Gaza superba by being more depressed, with stronger spiral grooving, a slightly smaller umbilicus, and more flattened over the sutures. The periostracum is olivaceous, polished, very thin and readily dehiscent.

McBurney's point is the name given to the point over the right side of the abdomen that is one-third of the distance from the anterior superior iliac spine to the umbilicus (navel). This point roughly corresponds to the most common location of the base of the appendix where it is attached to the cecum.

The horny operculum has 6-7 spirals. The shell has a slightly fugitive colour of pearly aquamarine or beryl. It is remarkably smooth, the only sculpture being the incised radiate sulculi around the umbilicus, and the fine spiral liration of the apical whorls. The simple peristome is remarkably thin and not in the least reflected.

The surface is smooth, except for the base which contains two or three very faint concentric striae. The circular aperture has a continuous peristome. The columella has a thick callus that connects to the convexity of the penultimate whorl. it covers for the greater part the umbilicus, that is reduced to a narrow, arched chink.

Callus is extending over the umbilicus so as to occlude it completely, giving a shape of oblique columellar end. The height of the shell is 30 mm. The width of the shell is 33 mm. The operculum is small, round, horny, thin, translucent, marked with a fine spiral line which coils about 13 in number.

There is no umbilicus or pit.Dall W. H. 1889. Reports on the results of dredging, under the supervision of Alexander Agassiz, in the Gulf of Mexico (1877-78) and in the Caribbean Sea (1879-80), by the U.S. Coast Survey Steamer "Blake", Lieut.-Commander C.D. Sigsbee, U.S.N., and Commander J.R. Bartlett, U.S.N., commanding. XXIX.

The white shells have a turbinate shape and a broad umbilicus. They are characterized by axial ribs and spiral cords, that form spines at their intersections. The lip is not thickened at maturity. It differs from the closely related genus Arene through its lack of shell pigments and in the spacing of the axial sculpture.

The body whorl is dilated, obtuse in the middle, spirally trilineate (one line above, two at periphery), somewhat convex beneath, with two zones of brown spots. The aperture is transverse, and scarcely sulcate within. The columella is nearly horizontal, twisted above, truncate beneath. The columellar callus forms a coating to the extremely oblique umbilicus.

The size of the shell varies between 7 mm and 13 mm. The very solid shell has a conicalshape and is angulate at the periphery, with a very shallow umbilicus. It is white, variegated with maculations and radiating zigzag stripes of purplish red. The five whorls are planulate and turgid below the subcanaliculate sutures.

These number about 20 on the upper surface of the body whorl, and a similar number on the base. A narrow smooth band winds round the peripheral angle. The umbilicus is margined by a broadly rounded funicle. The colour of the shell is pale pink, with radiate crimson streaks on the second and third whorls.

The height of the shell attains 6 mm, its major diameter also 6 mm. The small, solid shell has a globose-conic shape. It has a carmine colour with radial buff dashes, about eight to a whorl, reaching from the suture half-way to the periphery. The umbilicus and the bordering funicle is white.

Italian archaeologist Rodolfo Lanciani discovered the remains of the altar in 1902 near the Arch of Septimius Severus. It was first thought that the remains were of the Vulcanal. The altar stands in front of the Temple of Saturn, next to the Umbilicus urbis Romae, and south of the senaculum of the Roman Forum.

Five views of a shell of Helicigona lapicida lapicida Five views of a shell of Helicigona lapicida andorrica The shell of this species is approximately 20 mm in maximum dimension. The periphery of the shell is sharply keeled. There is a wide umbilicus. The peristome around the aperture is white and strongly reflected and lipped.

Species of Torresitrachia are characterized by their small to medium-sized, discoidal shell, and a loosely coiling umbilicus. Shells are a uniform brownish in color and exhibit a sculpture of radial ribs or periostracal hairs.Solem, A. 1979. Camaenid land snails from western and central Australia (Mollusca : Pulmonata : Camaenidae) I. Taxa with trans- Australian distribution.

Carinonautilus is a genus from the Upper Cretaceous of India, named by Spengler in 1919. Carinonautilus is a very involute form with high whorl section and flanks that converge on a narrow venter that bears a prominent rounded keel. The umbilicus is small and shallow, the suture only slightly sinuous. The siphuncle is unknown.

The aperture has a very deep sulcus nextto the suture. The outer lip in front of it is much produced, a feeble sulcus at the middle of the base. In front of the arcuate columella there is a smaller rounded indentation. Behind the columella there is a deep groove ending in a minutely perforate umbilicus.

His books on diseases of the larynx and on nasal suppuration have been translated into English.Archive.org Atlas and abstract of the diseases of the larynx.IDREF.fr A treatise on nasal suppuration Aside from otolaryngology, he is also remembered for his discovery of a large ecchymosis located in the umbilicus associated with acute pancreatitis, the Grünwald's sign.

Hebetoxyites is a genus of ammonoid cephalopod from the middle part of the Bajocian stage, middle Jurassic, included in the Strigoceratidae, Haplocerataceae. The shell is oxyconic, with a sharp rim but no keel, and involute, with the inner whorls hidden. The umbilicus is very small. Sides have a spiral ridge but are not striate.

Sculpture:The body whorl shows fine, close spiral threads of which every fourth is larger. At irregular intervals incipient varices traverse the whorl. On the penultimate whorl the spiral sculpture is more coarse and distant. The umbilicus is narrow, bordered by a slight rib, which, continuing to the anterior extremity, is there notched by the pseudocanal.

The shell is generally globose with an open but narrow umbilicus, the surface commonly reticulate resulting from longitudinal lirae crossing transverse striae. The ventral lobe of the suture is rather narrow with a median saddle about or little less than half the height of entire lobe. The first lateral saddle is subangular to angular.

Solariella is a genus of small to minute sea snails, marine gastropod molluscs in the family Solariellidae within the superfamily Trochoidea, the top snails, turban snails and their allies. This genus was founded by S. Wood for an English fossil trochid, conical in form, with tubular whorls and a deep umbilicus, its margin crenulated.

Hypoxynoticeras is an extinct genus of lower Jurassic ammonite that lived during Jamesoni zone of lower Pliensbachian. Animals belonging to this genus had small platycone shells, of which umbilicus made 25—30% of diameter. Keel was strong and ventrolateral shoulders were prominent. It is possible, that it was just a microconch, or juvenile of Radstockiceras.

The sutures are channeled. The umbilicus shows a narrow chink; The columellar tooth is situated high on the parietal shield. J.J. van Aartsen, E. Gittenberger & J. Goud, Pyramidellidae (Mollusca, Gastropoda, Heterobranchia) collected during the Dutch CANCAP and MAURITANIA expeditions in the south-eastern part of the North Atlantic Ocean (part 1); CANCAP-project . Contributions, no.

For terms see gastropod shell The 2.0-2.5 x 2.8-3.5 mm shell is broader than high. The colour is yellowish brown. The shell surface on the upper side is rather pale, the lower side is rather silky and smooth. There is no umbilicus and the last whorl with a trace of a keel.

Omphalomesenteric duct cysts (ODC, also known as an omphalomesenteric duct remnant or vitelline cyst) are developmental defects relating to the closure of the omphalomesenteric duct. It usually disintegrates within six weeks of gestation, but remnants of the cyst can sometimes be found along the intestines or umbilicus. Any remnants can be removed via surgical means.

There is a secondary sculpture of fine radial threads which sometimes crowd the interstitial spaces of the spirals. On the body whorl are about thirty-two broad spiral cords, and on the penultimate ten. In their interstices one or more spiral threads may arise. A funicular rib on the anterior end of the shell encloses a small false umbilicus.

It is rather widely umbilicate. The 5½ convex whorls are separated by a narrowly canaliculate suture, and encircled by granose lirae, about 7 on the penultimate whorl . The body whorl has a roundly angulated periphery and is encircled by about 14 granulose lirae. The white umbilicus is surrounded by a white granuliferous rib, and with a smooth rib within.

The spire is high and very slightly scalar. The sharp apex is minute, flattened on the one side, with the very small embryonic 1¼ whorl rising sharply on the other. The spire contains 7 whorls, that increase in size regularly. The body whorl is small, from the large part of it cut out by the umbilicus.

The same sculpture persists on the body whorl, where the tubercles, about 30 in number, are compressed and show a tendency to become double. The crenules of the keel are slightly concave from above to below. The base of the shell is nearly flat with 5 concentric beaded lirae. The beads bordering the umbilicus are the largest.

The width of the shell is 7.1–11 mm and the height of the shell is 4.0-4.5 mm. The width of the last whorl is 1.9-2.0 mm; the width of the umbilicus is 0.7-1.1 mm. The color of the tentacles, head and neck is light-grey. The color is the sole is white- yellow.

A urachal cyst is a sinus remaining from the allantois during embryogenesis. It is a cyst which occurs in the remnants between the umbilicus and bladder. This is a type of cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterized by abdominal pain, and fever if infected.

It is more involute than its predecessor C. exaratum and has higher whorls. Sloping umbilical wall is forming a funnel shaped umbilicus and also a more compressed whorl section. Keel is strong. Nearly all ribs are single and they are of falcoid shape.. They are weak to moderate on microconchs, but stronger in middle growth stage of macroconchs.

It is angled at the periphery, at the base and at the umbilical margin. The sculpture of the shell shows above numerous closely packed strong radial ribs, which project as denticules from the periphery. Between the basal and peripheral angles the ribs descend perpendicularly and are crossed by fine spiral threads. Crossing the base the ribs ascend the umbilicus.

Agathiceratidae, as revised, makes up the goniatitid superfamily Agathiceratoidea. Agathiceratidae, which lived from the Upper Carboniferous (Pennsylvanian) to the Middle Permian, combine related genera with subdiscoidal to globular shells that have a small umbilicus and goniatitic sutures and are prominently longitudinally lirate. (Miller et al. 1960) The explanation for the Agathiceratidae is that for the Agathiceratoidea.

The Cravenoceratidae is one of six families included in the ammonoid superfamily Neoglyphioceratoidea, which lived during the latter part of the Paleozoic era. Cravenoceratid genera have moderately evolute to involute, broad or thickly discoidal shells with a moderately narrow umbilicus. The surface is generally smooth, dominated by growth striae. Spiral ornamentation may be present, but reticulate ornament is absent.

Prolecanitoidea is a taxonomic superfamily of ammonites, fossil cephalopods. This is one of two superfamilies in the Prolecanitida. The other is the Medlicottioidea. The Prolecanitoidea are found in the Upper Devonian to the Middle Permian and are recognized basically by their generally smooth discoidal to lentincular shells which have a large umbilicus and goniatitic to ceratitic sutures.

Sphenarpites is an extinct genus of cephalopod belonging to the family Hildoceratidae. Only one specimen is known, which has been found in Kelat, Baluchistan, in today's Pakistan. Its involute, oxycone shell has very small umbilicus and umbilical wall is smoothly rounded. Suture is reduced with 1 or 2 adventitious saddles and about 10 auxiliary saddles in external suture.

The conchological characters of the species belonging to the genus Chloritis are the more or less compact shells, the biconcave or a hardly elevated spire. The first whorls are quite narrow, rounded, the apical ones with regularly arranged granules or hair pits. Last whorl is widened suddenly, with a more or less open umbilicus. The aperture is lunate.

The minute nucleus is flattish. The body whorl contains four strong, beaded, spiral cords with subequal interspaces, peripherally. Between these and the suture, there are three slightly smaller similar cords, the space at the suture giving a channeled effect. On the base there are two less prominent cords and two wider nodulous ridges around the deep, rather narrow umbilicus.

The sutures are deeply impressed. The seven whorls are well rounded, with close lamellose incremental striae, and corrugated by obliquely descending subtuberculose folds. The base is flattened bearing concentric densely squamose lirae, deeply concave in the center, and indented in the place of the umbilicus. The aperture is transversely oval, very oblique, pearly and somewhat corrugated within.

The basal keel encircles the umbilicus, which is particularly large and deep compared to the size of the shell. The aperture has a square shape. The thin outer lip is angulate.Melvill (1904) Descriptions of 28 species of Gastropoda from the Persian Gulf, the Gulf of Oman and the Arabian Sea; Proceedings of the Malacological Society of London v.

The height of the shell attains 2 mm, its diameter 3 mm. The delicate, white, umbilicated shell contains four whorls. it is destitute of spiral ribs. The longitudinal riblets are very close and fine, about 26 in number on the five-angled body whorl, that surround the umbilicus at the base being the strongest and most conspicuous.

The shell is 13 to 16 mm in height and 11 mm to 15 mm in width in the adult. The upper whorls are almost flat so that the shell has a short blunt spire, the last whorl is inflated and predominating. The aperture is more than 90% of the shell height. The umbilicus is closed.

Sholakoceras is an extinct genus of nautiloid cephalopods from the Lower Permian of southern Russia, included in the Tainoceratacean family Rhiphaeoceratidae,(order Nautilida). The shell of Shalakoceras is evolute with a perforate (see through) umbilicus. Whorl sections are subquadrate with the ventral and lateral sides flattened and ventral and umbilical shoulders rounded. Lateral areas bear short, slightly oblique ribs.

The spiral sculpture begins at the umbilicus. Outside the carina, which is simple, there are two strong broad subnodulous spirals separated by a deep line, then fourteen or more equal smooth flattish spirals with narrower interspaces and obsolete spiral striulae here and there. Then follows a smooth or slightly striate peripheral space. All the preceding are straw-colored.

The entire base sometimes shows fine low concentric lirae, but usually they nearly disappear there, becoming visible again around the umbilicus. There are often traces of a few obscure spiral riblets above the supra-peripheral carina. Longitudinally the entire surface is marked by regular. rather close waves or folds, so low and obtuse as to be frequently almost indistinguishable.

The white columella is perforated by the wide and deep umbilicus, and with a spiral groove extending to the base. The oval operculum is flat within, with four whorls. Its nucleus is situated one-third the distance across the face. Its outside is white, excavated at the center, with two strong spiral ribs, the inner one decidedly the stronger.

The periphery of the body whorl is marked by a groove. The base of the shell is well rounded. It is marked by six strong, spiral cords which decrease successively in size and spacing from the periphery to the umbilicus. The grooves between the spiral cords are marked by slender threads corresponding to the axial ribs.

The height of the shell attains 39 mm. The umbilicated shell is large, polished, solid, and contains 8 whorls. It is straw-yellow lineated with red-brown, and has a broad rose-colored peripheral band. The walls of the umbilicus are marked with incremental lines, slightly excavated near the carina, above convex, the convexity revolving with the whorl.

Hildoceras bifrons has a slender, flattened, deeply embossed spiral shell with dense transverse ribbing and a deep groove that runs parallel to the spiral. The umbilicus is convex and has gently sloping sides. The aperture is circular. The fossils come in two sizes, the macroconch (female) ranging in size from in diameter and the microconch (male) which ranges from .

The size of the shell varies between 9 mm and 22 mm. The shell is broadly umbilicated and the spire has a depressed conoidal shape. It is sculptured with very fine, hardly visible spiral striae and is otherwise smooth. It is very shining, ashen-whitish, painted with light yellowish to light brown confluent flammules above and at the umbilicus.

The rather large and deep umbilicus is cylindrical. It is bordered on the outer edge by an obtuse angle, a second angle appearing a little way within the orifice. The space between the two angles is slightly flattened, numerous very distinct close-set plicae traverse this space, crossing the angles. The rather large, diagonal aperture is rounded-trapezoidal.

The JetLev was the first hydroflight jetpack on the market, and its makers were awarded the first patents, in 2008, for hydrojetpacks. The JetLev has the appearance of a typical jet pack, with two nozzles on a backpack propelling the rider upwards. It just has an umbilicus to the powering jetski that provides the water for the thrust used.

The conical, solid shell has well-rounded globose whorls with six to eight smooth spiral cords per whorl and no umbilicus. Its base is flattened. The surface is encircled by numerous spiral smooth riblets, their interstices closely finely obliquely striate. There are usually seven to nine riblets on the penultimate whorl, about nine on the base.

The 6 to 7 whorls are rather rounded with a convex base, the last one is scarcely angled. The margin of the narrow umbilicus is dentate. The columella is very oblique, not solute above and terminates below in a simple, small denticle. The outer lip is thickened within with five folds but near the edge with numerous wrinkles.

The body whorl however has eight, two new ones having been intercalated on the lower part, the eighth prominent, forming the periphery. The base of the shell is rather convex, and has nine close granulose lirae. The granules on the border of the umbilicus are but slightly developed. The aperture is about as in Clanculus pharaonius.

The base of the shell is eroded in front of the aperture. The aperture is oblique. The columella is short, obtusely subdentate near the base, spreading at the insertion into a heavy callous, which covers the umbilicus. This species is similar to Phorcus turbinatus in form, but usually has the outlines of the spire more convex.

They are smooth except on the base, where fine concentric lines are visible under a lens. The aperture is oblique. The lip is thin, acute, brilliantly iridescent within with green predominating. The thin columella is arcuate, obviously toothed near its junction with the axis above, and covering the place of the umbilicus with a white pad of callus.

The height of the shell attains 8 mm, its diameter 5 mm. The rather solid shell has an elongate-conical shape. It is imperforate, but with a groove and pit or even a slight perforation at the place of the umbilicus. It is whitish, longitudinally clouded with brown or pink, often showing white opaque scattered dots.

Promicroceras is an extinct ammonite genus from the upper Sinemurian (Lower Jurassic) of Europe, named by Leonard Spath in 1925. Promicroceras is included in the family Eoderoceratidae, which is part of the ammonitid superfamily Eoderoceratoidea. Shells are evolute with an open umbilicus; strongly ribbed, ribs flattened on the venter, and with small spines without distinct tubercles.

The outer and basal margins are rounded in outline, thin, thickened interiorly, with 10 spiral lirae. The columellar margin is cylindrical, only slightly curved, with a rather strong transverse fold. Its base runs without angle in the basal margin, and is slightly expanded over the umbilicus. Its upper part is connected by a thin layer with the outer margin.

Near the apex they become obsolete. At the aperture is a shallow sulcus between the keel and the suture and a smaller one at the middle of the base. There is a sharp notch below the end of the thin, arcuate projecting columella, behind which is a moderately large twisted umbilicus. The body shows no glaze.

It has ten to twenty faint spiral threads on the upperside of the body whorl. The last of these which joins the lip is much stronger than the others. A little remote and below is a thread forming the keel, below which, and nearer, are two other strong threads. Round the umbilicus are also two strong threads.

Liguus shares the distinguishing characteristics of other bulimulid gastropods in the subfamily Orthalicinae: large size (about in length), imperforate umbilicus, a jaw consisting of a limited number of broad plates, and the presence of a pineal gland.Pilsbry H. A. (1946). Land mollusca of North America north of Mexico vol. II part 1. Acad. Nat. Sci. Philadelphia. p. 29.

The narrow umbilicus is deep, and is bordered with a raised ridge, or is closed up. The foramen is large, and distant from the margin, to which a furrow joins it. The fasciole is extremity short, terminating half a whorl behind the aperture. it is bordered by keels and is traversed by lamellae, which correspond to the longitudinal ribs.

Medsurg Nurs . 2012;21(3):146–150 The examiner also typically listens to the two renal arteries for abnormal blood flow sounds (bruits) by listening in each upper quadrant, adjacent to and above the umbilicus. Bruits heard in the epigastrium that are confined to systole are considered normal.MD, Lynn B. Bates' Guide to Physical Examination and History-Taking, 11th Edition.

Oppelia is a haploceratoid ammonite and type genus for the Oppeliidae that lived during the Middle Jurassic. Shells of Oppelia are involute with a small to moderate size umbilicus, bluntly rounded to sharp venter, and deeply impressed dorsum. Sides are generally smooth but may be variously ribbed on the outer flanks. Similar and related genera include Oxycerites and Oecotraustes.

Labyrinthoceras is an extinct cephalopod genus included in the ammonoid family Sphaeroceratidae, a member of the superfamily Stephanoceratoidea, that lived during middle of the Jurassic Period. Labtrinthoceras is described as large, round-whorled with an open umbilicus; body chamber smooth with a terminal constriction. The chambered phragmocone is finely ribbed. Coiling is eccentric, a character of the family.

Before rupture, an AAA may present as a large, pulsatile mass above the umbilicus. A bruit may be heard from the turbulent flow in the aneurysm. Unfortunately, however, rupture may be the first hint of AAA. Once an aneurysm has ruptured, it presents with classic symptoms of abdominal pain which is severe, constant, and radiating to the back.

For terms see gastropod shell The 15 x 12–23 mm. shell has 4.5-5.5 convex whorls. The last whorl is initially angulated or rounded. The aperture is rounded with a whitish or reddish lip inside and margin is not reflected, The umbilicus is always open, 1/10-1/6 of shell diameterand sometimes slightly excentric.

The shell lacks an umbilicus. The white outer lip is sometimes checkered with brown patches. The inside of the shell is chocolate brown. The width of the shell ranges from 10 to 12 mm at maturity, with an average length of 16–38 mm. Shell height can reach up to 30 mm,Common periwinkle at marlin.ac.

Eubostrychoceras is a genus of helically wound, corkscrew form, heteromorph ammonite which lived during the Upper Cretaceous (M Turonian - Campanian). The genus is included in the ancycleratid family Nostoceratidae. The shell of Eubostrychoceras is a loosely to tightly wound spiral forming a corkscrew with an open, empty umbilicus in the middle. coiling is commonly dextral (right hand).

The base of the shell is a little rounded, radiately lamellose striate and concentrically lirate with three to five lirae, mostly tuberculate, especially in the young. The oval aperture is transverse, channelled at its outer angle. The short columella is arched. The place of the umbilicus is excavated, whitish, bounded by an intensely orange vermillion tract.

The body whorl is one and one-half armed with erect long stout tubular spines on the carinae, ten to twelve in number on the last whorl, usually tinged with green. The ovate aperture ovate, pearly white and iridescent within. The columella is thickened below, deflexed, produced and somewhat channelled, excavated at the conspicuous umbilicus. The operculum is subcircular.

Bisatoceras is a late Paleozoic (Upper Mississippian - Upper Pennsylvanian) Ammonoidea, a member of the goniatitid family Bisatoceratidae. Bisatoceras was named by Miller and Owen in 1937 and has a subdiscoidal shell with a very narrow or closed umbilicus. Whorl height exceeds with at maturity, immature growth stages are globular. Growth lines are usually biconvex, forming ventral and lateral sinuses.

Sculpture : the whole shell is beautifully and delicately cancellated. There are seven spiral cords, two on the shoulder, three on the periphery, one at the margin of the umbilicus and one within it. The upper pair ascend the spire, the lowest peripheral is stronger than the rest. On the last whorl, there are about twenty radials.

These ascend the spire, projecting like spokes over the suture. Arising in the sutural trench, they are dormant on the shoulder and are strongly expressed on the periphery. They again fade on the base, but revive in the umbilicus, where they project far into the cavity. At the intersection of the spirals, they form polished knots.

The two lateral lobes are asymmetrically trifurcated, sections sharply pointed. The first lateral saddle (closest to the venter) is fairly evenly rounded, the second and third are narrower and asymmetric, leaning away from the venter and toward the umbilicus. Monophyllites, which extends through the Middle Triassic into the Carnian is similar, differing in the details of the suture.

The 5.4-8.1 × 7.4-12.2 mm. shell of this species has, in comparison with Candidula intersecta, whorls that increase more rapidly, the inside of the umbilicus is very narrow, but remarkably wider at last whorl. The shell is light brown or sandy-coloured with pale colour bands. It is usually flatter and larger than the shell of C. intersecta.

The columella is strong and thick, arcuate above, spread upon the body whorl and nearly over the umbilicus in a pad of callus, which is either white, pink or deep crimson. The callus is kidney-shaped, but slightly convex, filling the umbilicus except a narrow chink. From the outer termination of the callus an arcuate groove extends to the base of the columella, within which the surface of the shell is radiately finely striate and darker colored.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia Radula of Ethalia guamensis Radula: The teeth, especially those of the central part are very thin and transparent, without distinct cusps; the rhachidian tooth (R) is broadly winged, bow- shaped, at its upper part it is thickened, a true cusp cannot be detected.

A sei whale showing distinctive upright dorsal fin The whale's body is typically a dark steel grey with irregular light grey to white markings on the ventral surface, or towards the front of the lower body. The whale has a relatively short series of 32–60 pleats or grooves along its ventral surface that extend halfway between the pectoral fins and umbilicus (in other species it usually extends to or past the umbilicus), restricting the expansion of the buccal cavity during feeding compared to other species. The rostrum is pointed and the pectoral fins are relatively short, only 9%–10% of body length, and pointed at the tips. It has a single ridge extending from the tip of the rostrum to the paired blowholes that are a distinctive characteristic of baleen whales.

The basal face of the shell is subconvex, but quite flat in the centre, with a shallow groove between the peripheral keel and the first of the basal lirae, this space is rather smooth, though crossed by plicae running from the peripheral spipes in an oblique direction. The outermost of the basal lirae, which is not broad, is followed by two similar ones, about as strong as their interstices, the central ones, five in number, increasing in breadth towards the centre, (one of them nearly double) being larger than the interstices These lirae are connected by small radiating riblets in the interstices. The umbilicus is bordered by a liration, consisting of a row of subquadrate beads This umbilicus is pervious and funnel-shaped. Its wall is radiately striated and has one faint spiral rib.

Encoiloceras is a genus of Tainoceratids, a nautiloid cephalopod in the order Nautilida that has been found in Upper Triassic (Carnian) sediments in the Alps and Hungary. Encoiloceras has an evolute shell with a wide umbilicus and large umbilical perforation in the middle. The whorl section is subquadrate with a rounded venter. Flanks bear thick, foldlike, ribs that thicken at the ventral shoulders.

Liroceras has a temporal range from the Mississippian to the Permian period, longest of the Liroceratidae. It has been found the North America, Europe, China and the East Indies. A similar genus, Condraoceras, differs in having a circular cross section and shallow ventral and lateral lobes. Another, Bistrialites, also has a reniform whorl section but differs in having a large funnel-shaped umbilicus.

The center of the base has another slightly beaded thread. There is another formed of remote rounded tubercles, defining the umbilicus, within which is a very slight furrow and an ill-defined ridge. The apical whorls are ribbed, but the ribs gradually break into the scarcely connected tubercles of the body whorl. The lines of growth are hardly perceptible, except on the base.

The size of the shell varies between 6 mm and 18 mm (1/4 to 3/4-inch). The thin and delicate shell is rather large for the genus; it is whitish, brilliantly iridescent or pearly, externally and internally. It has a broad, conical shape. It is turreted, wider than it is high, with a convex base, and deep umbilicus.

The 3-6 x 5-11 mm shell has 5-6 moderately convex whorls which are rounded or very slightly keeled at the periphery. The aperture has a thin white lip inside. The umbilicus is open and usually wide at 1/8-1/4 of shell diameter. In colour the shell is brown to cream, sometimes with a light band at the periphery.

The Macronesian flora include three genera from the Sepervivoideae, Aeonium, Aichryson and Monanthes (Aeonium clade), together with several Sedum spp. and one species of Umbilicus (Rhodiola). North America was reached at least twice, once by an ancestor of Parvisedum and Dudleya, and once by a subclade of Acre. For a mapping of morphological features and biogeography on the phylogenetic tree, see Fig. 3.

Pachylyroceras produced a large shell that is moderately evolute to moderately involute and thickly discoidal to subglobular, with a rather wide umbilicus. Surface sculpture consists of coarse, widely spaced longitudinal lirae. Constrictions where present are wide and deep. Its suture has a narrow bifurcated ventral lobe with slightly divergent to subparallel sides and a median saddle less than half the height.

Tycho is named after the Danish astronomer Tycho Brahe. Like many of the craters on the Moon's near side, it was given its name by the Jesuit astronomer Giovanni Riccioli, whose 1651 nomenclature system has become standardized.Riccioli map of the Moon (1651) Earlier lunar cartographers had given the feature different names. Pierre Gassendi named it Umbilicus Lunaris ('the navel of the Moon').

These are sculptured with longitudinal, close, radiating lamellae, angular in the middle, and little, elevated, transverse lines. The base of the shell is ornamented with concentric elevated lirae. This species is elevately turbinate, with two conspicuous carinate whorls and a deep perspective umbilicus. The fine lamellae of the upper part of the whorls are bent or angulated in the middle.

The typical Cadoceras shell is strongly ribbed, subglobular, with a broadly rounded venter, strongly embracing whorls, deep umbilicus, and a smile-like crescent-shaped aperture. Ribs arise from the umbilical shoulder and bifurcate (divide in two) about mid flank and cross the venter without interruption. Species vary in the nature of ribbing and roundness of the umbilical shoulder.ammonites.fr Cadoceras entryjsdammonites.

Cibolaites is a moderate-sized, somewhat involute genus, with a moderate umbilicus, that bears broad rounded ribs on the flanks which bifurcate from the umbilical shoulder on larger specimens. Whorl section is broadest though the umbilical shoulders, flanks converge moderately on a broadly rounded venter. which bears three rows of distinct, commonly elongate, nodes. (Plate 2, figs 1-9, Cobban and Hook, 1983).

The length of the shell size varies between 15 mm and 45 mm. The shell is heavy and coarse with rough, grained surface with moderate sutures between rounded whorls. The body whorl is swollen and the penultimate whorl somewhat less. The shell shows a rounded keel (a spiral ridge marking a change of slope) and an umbilicus sealed with a callus.

The outer lip is thin, acute, and very narrowly margined with yellow, succeeded by a line of black, within which lies a band (about 2 mm wide) of opaque white. The columella is arcuate above, partly surrounding the umbilicus with a white callus. It is straightened in the middle. The umbilical tract lis arge, white, funnel-shaped, and bounded by a carina.

The height of the shell attains 11 mm, its diameter 14 mm. The umbilicate shell has a depressed-globose conic shape. It is, polished, shining, blackish, olive or purplish brown, unicolored, dotted or tessellated with white, often with short flames of white beneath the sutures and always more or less marked with white around the umbilicus . The spire is conical.

The shell periphery is usually rounded and the last whorl does not descend below the preceding whorl but is parallel to the preceding suture. The outer wall of the last whorl generally possesses two short longitudinal furrows that correspond with internal apertural lamellae. The umbilicus is narrow and deep. The semi-ovate aperture has an expanded peristome with a reflexed lip.

The Naticinae are a subfamily of medium to large-sized predatory sea snails, marine gastropod molluscs in the family Naticidae, the moon snails. The Naticinae are characterized by their calcareous operculum and by the presence of a distinct funicle within the umbilicus, which is observable in most species. It is mainly a tropical group, which is brightly colored and patterned.

The five whorls are deeply convex, while the body whorl is subangulate. The first whorl of the five is discoidal. It is characterized by extremely minute wrinkling over the whole surface, only discernible under the microscope when quite fresh. The umbilicus is very large when young, and sharply keeled; when adult it is often nearly filled up by the callous lip.

Surgical incision site of a female cat The surgery can be performed using a traditional open approach or by laparoscopic "keyhole" surgery. Open surgery is more widely available, as laparoscopic surgical equipment costs are expensive. Traditional open surgery is usually performed through a ventral midline incision below the umbilicus. The incision size varies depending upon the surgeon and the size of the animal.

The surgeon watches on a screen during the operation. The first port is made just behind the umbilicus and the camera is inserted. The abdomen is inflated with carbon dioxide gas to create a space in which to operate. A second port is introduced a few centimeters in front of the navel and a long grasping instrument called a Babcock forceps is inserted.

Diver in Sladen Suit The Sladen Suit was a heavy type of British divers' drysuit made by Siebe Gorman. It is entered by a wide rubber tube at the umbilicus: this tube is folded and tied off before the diver dives. It was used by British manned torpedo riders and for general underwater work. It was sometimes nicknamed "Clammy Death".

The whole surface bears numerous low, smooth spiral striae, which are often subobsolete on the body whorl, and it is then nearly smooth. The base of the shell is concave in the middle. The aperture is rounded-quadrate, smooth within or finely lirate. The columella is slightly sinuous, bidentate at base, expanding in a callus above, which slightly impinges upon the umbilicus.

The base of the shell is rather flattened, somewhat concave around the umbilicus, and generally eroded in front of the aperture. The aperture is oblique. The outer lip beveled to an acute edge, which is usually margined with green and is sulcated or crenulated, the furrows corresponding to the lirae of the outer surface. The pearly throat is also more or less sulcate.

The 5-6 whorls are somewhat flattened below the sutures, with a superficial spiral line, and marked with light incremental striae. The large apertureis very oblique, ovate, silvery inside and rounded below. The outer lip is slightly fluted within. The white columella is wide and beas on its face a longitudinal rib which rises in the region of the umbilicus.

The suture is deep but not channelled. The whorls are very round, but the spire is hardly rising above the body whorl. The base of the shell is rounded, with a very narrow umbilicus, into which the whorl descends without any angle or other change of curve. The large aperture is circular, the upper part a little angulated at the suture.

The oblique columella is concave above, cylindrical, and has a groove marking the place of the umbilicus. The base color is a light reddish brown with irregular maculations of darker brown above and a row of small alternating white and dark brown spots encircling the whorls. It has a brown-articulated peripheral girdle. The base of the shell is generally not marked.

The whorls are marked by extremely fine, closely placed, wavy spiral striations, which are visible only under very high magnification. The periphery of the last whorl is somewhat angulated. The base of the shell is very broad, gently rounded, somewhat pinched at the narrow umbilicus. The aperture is elongate-ovate, somewhat prolonged at the junction of the outer lip and columella.

The sutures are subcanaliculate. The acute apex is eroded. The following whorls are finely granose in spiral series, of which there are 10 to 12 on each whorl. The body whorl is somewhat deflected anteriorly, bearing about 30 spiral granose ridges, very close and fine upon and below the periphery, coarser above and around the umbilicus, the interstices obliquely striate.

Its color varies between yellow to reddish-brown with some dark axial streaks. The slightly convex whorls are smooth, but show, under magnification, numerous, very fine spiral threads. This species shows great variations in strength and spacing of the spiral cords with, in some specimens, the major cords more prominent than normal. As typical for this genus, there is no umbilicus.

The lip is not much thickened within. The short columella is obsoletely subdentate at its base. Above at the insertion it shows a heavy white callous spread upon the base, invading the umbilicus, and wholly closing it, or leaving only a narrow pit. This species is quite variable in coloration, the white appearing either in oblique zigzags or in spots.

The wide and deep umbilicus of Cittarium pica is very distinctive. This shell has been polished. Drawing of a shell of Cittarium pica The shell of this species can be up to 137 mm in maximum dimension. It is very thick and heavy, having an outline that is between trochiform and turbiniform in shape, with rounded shoulders and a somewhat low conical form.

Cleoniceras is a rather involute, high-whorled hoplitid from the Lower to basal Middle Albian of Europe, Madagascar, and Transcaspian region. The shell has a generally small umbilicus, arched to acute venter, and typically at some growth stage, falcoid ribs that spring in pairs from umbilical tubercles, usually disappearing on the outer whorls. Cleoniceras is included in the subfamily Cleoniceratinae.

Amplirhagada- species exhibit variable shells ranging from broadly conical to highly turreted in shape. Shells are comparatively large, ranging from about 10 to 25 mm in height and from about 15 to 30 mm in diameter. Shells are often banded but uniformly brown species are also known. The umbilicus is narrowly winding and open, partly or completely concealed by the columellar reflection.

On the base of the shell there are 8 concentric lirae, alternately larger and smaller, the inner one bounding the umbilicus and spirally entering it. The large aperture is oblique, finely sulcate, pearly and iridescent inside. The outer lip is thin. The columella is arcuate, not toothed, a trifle reflexed above, connected with the upper lip by a short, shining, white callus.

Patera is a genus of land snails in the family Polygyridae. The name is from the Latin patera ("a saucer"), and refers to the highly depressed, saucer-like shape of the shells of these snails. In addition to flattened shells, members of the group have an imperforate umbilicus and a single tooth on the parietal wall of the aperture.Pilsbry, H. A. (1940).

The base of the shell is covered by about fourteen rounded ridges and furrows, which are rather stronger toward the center, the last one, forming the edge of the umbilicus, being specially so. Color: The surface is a dead slightly creamy white, formed by a thin calcareous layer through which the underlying nacre shines. The spire is high and conical. The apex broken.

The periphery of the body whorl is very strongly angulated. The base of the shell is very short, slightly concave, broadly, openly umbilicated, and marked by 12 depressed, rounded spiral cords of somewhat varying width. The entire surface of the shell is marked by slender lines of growth which extend over the base and into the umbilicus. The large aperture is very oblique.

The subsequent whorls are moderately inflated. They are separated by a deep but not channelled suture, having a rounded periphery, a wide, completely pervious umbilicus, and a large, very oblique, iridescent aperture. The axial sculpture consists of very fine silky incremental lines. The spiral sculpture consists of low flattish threads separated by narrower interspaces sometimes carrying a finer intercalary thread.

Sometimes, the importance of the navel was further enhanced by connecting with a line from the navel towards the chest. Early Japanese poems feature many references to the female navel. In some, the word navel actually refers to an indentation or hole instead of the belly button. The shape of the umbilicus of a newborn baby would be discussed at length.

The abdominal area is the region between the chest and the pelvis. The breast is called the mamma or mammary, the armpit as the axilla and axillary, and the navel as the umbilicus and umbilical. The pelvis is the lower torso, between the abdomen and the thighs. The groin, where the thigh joins the trunk, are the inguen and inguinal area.

It is silvery within. The oblique columella is slightly concave, excavated at the position of the umbilicus, with a spiral white rib. The parietal callus covers over half the base of the shell. The operculum is white outside, excavated on each side of a strong granulose curved central rib, the terminations connected by a shorter ridge curved in the opposite direction.

The apertural margin is white and usually with a white layer at the parietal side. The parietalis is very strong and horizontal and often a small second parietalis is present. The columellaris is strong and the umbilicus is usually covered. The form denticulata has 3-6 short and thin folds (like drops) near the palatal margin at the inner lip.

They number seven or eight and cover the base of the shell and the umbilical depression. The umbilicus is imperforate or represented by a very narrow chink. The surface of the pale shell is nearly smooth, except for very fine, minute striations or growth lines, which give the surface a dull appearance. The freshest specimens have only a slight luster.

The height of the shell attains 1.5 mm, its diameter 2 mm. The shell consists of about three convex whorls forming a comparatively low, somewhat depressed spire. The entire surface below the relatively large, little raised, smooth nuclear whorl, is covered with raised, rounded, well- separated, revolving microscopic threads, most distinct on the base. The small umbilicus is scarcely more than a chink.

The five whorls of the teleoconch are inflated, well rounded, their summits appressed. They are marked by fine, retractive lines of growth and numerous fine, wavy, spiral striations between the sutures and on the base. The posterior half of the base has, in addition to the above marking, three broad, low, feeble, raised, spiral threads. The umbilicus is very narrow.

The last whorl is 75% of the shell height and the apex is pointed. The aperture has a white layer at the parietal side, the parietalis (the spiral ridge on the parietal region projecting into the interior of the shell) is usually strong. The columellaris (or internal lip of the shell aperture) is moderately or indistinctly developed. There is no umbilicus.

The eponymous phenomenon known as the Sister Mary Joseph nodule refers to a palpable nodule bulging into the umbilicus as a result of metastasis of a malignant cancer in the pelvis or abdomen. She pointed Mayo's attention to the bulge, and he published an article about it in 1928, although the actual term was not coined until 1949 by Hamilton Bailey.

Zetoceras is an extinct ammonoid cephalopod genus from the suborder Phylloceratina that lived during the Early and Middle Jurassic in what is now Europe, and is included in the (family) Phylloceratidae. Zetoceras has a compressed involute shell with a very small umbilicus. The suture is phylloid, as for the suborder,with tall primary sutural elements. Saddles commonly have tetraphyllic endings.

The ovate aperture is whitish, marked likewise, with a few brown lines towards the depth of the cavity, exhibiting pretty distinct furrows. The outer lip is thin, terminated below by a small siphonal canal, at its union with the columella. The columella is slightly arcuated, with three folds at its base, the first very prominent. The umbilicus is indistinctly marked.

The most important shell characters for identification of Gudeodiscus giardi include: high and rather sharply defined shell shape, narrow umbilicus (for the genus Gudeodiscus) and thick peristome. The size of the shell is small to large. The shape of the shell is high and rather sharply defined. The color of the shell is brownish, but some Chinese populations are small and yellow and translucent.

In an open radical cystectomy a large incision is made in the middle of the abdomen from just above or next to the umbilicus to the pubic symphysis. The following information provides general steps to the procedure and may occur in varying order depending on the surgeon. The ureters are located and cut free from the bladder. The bladder is separated from surrounding structures and removed.

The outer lip is thin and broken, not descending. The inner lip is shortly but flatly bent over the umbilicus, and here it is patulous and sinuated, it then advances in a straight line toward the base. It is toothed in the middle by a strongish spiral protuberance at which point it projects. But from this to the junction with the base it is thin and retreats.

The spire is low and scalar. The apex is flattened, the embryonic 1½ whorl, though somewhat tumid and large for the genus, being somewhat immersed. The 7 whorls show a regular and slow increase until the last, which increases somewhat more rapidly. Angulated above, tumid on the base, where (unlike Carenzia carinata (Jeffreys, 1877)) the edge of the umbilicus is the most projecting part.

Below it is traversed by 7 to 8 spiral granose ribs, above it with longitudinal, oblique, rather separated striae and two spiral, slightly marked series of granules; The body whorl is obtusely bicarinate. The slit fascicle has a semicircular, delicate, impressed stride. It has a round and very deep, pervious umbilicus. The species has a (thin yellow in juvenile examples) operculum that completely seals the subquadrate aperture.

Falcitornoceras is a goniatitid ammonite from the Late Devonian, early Famennian, that has been found in France and Spain. Falcitornoceras was named by House and Price, 1985, and is the type genus for the subfamily Falcitornoceratinae. The shell of Falcitornoceras is strongly involute, lacking an umbilicus. Juvenile stages have falcate ribs which cross the ventral rim; the ventro-lateral area bears weak to strong furrows.

Herman Melville called the blue whale "sulphur bottom" in his novel Moby Dick due to the accumulation of diatoms creating a yellowish appearance on their pale underside. The name rorqual comes from the Norwegian word rørhval, a reference to the whale’s throat grooves, which are an elastic structure of blubber and muscle also known as the ventral grove blubber extending from the chin to the umbilicus.

Neoconorbina is a genus of recent (Holocene) discorbacean foraminifers related to Rosalina with a low conical trochoidal test, circular in outline. The conical side is the spiral side, on which all three whorls are visible, the final chamber taking up most of the periphery. The umbilical side is flat to concave. exposing only the three to four chambers of the final whorl around an open umbilicus.

The last whorl descends very deeply toward the aperture, with a strong keel at the shoulder, occupied by the anal fasciole, and another keel at the periphery, the space between them concave. Below this carina there are about 3 rather separated spiral lira, and around the umbilicus three more. The keels are obsolete for a short distance behind the aperture. The fine growth striae are scarcely perceptible.

In human anatomy, superior epigastric vein refers to a blood vessel that carries deoxygenated blood and drains into the internal thoracic vein. It anastomoses with the inferior epigastric vein at the level of the umbilicus and drains the anterior part of the abdominal wall and some of the diaphragm. Along its course, it is accompanied by a similarly named artery, the superior epigastric artery.

The columellar margin is briefly reflected at the corner. The whorls are smooth, channelled at the sutures, ornamented just below them with a row of raised coronated nodules, less distinct on the front of the basal whorl – this materially aids in giving the shell a slightly angled appearance. It is white, with many flame-like markings. The umbilicus is deep and very slightly contracted.

Like other nautilus species, A.perforatus has a coiled shell, shell covering its internal body. The shell has multiple chambers, the outermost chamber being where the nautilus lives. In addition the organism possesses tentacles that form two rings around its mouth. A. perforatus shows a shell shape and coloration very similar to that of A. scrobiculatus and shares with this species the characteristic open umbilicus.

The base of shell is sculptured with two spiral grooves and a number of very fine spiral striae. It is painted with a zone of fine, closely set cinereous flammules, within which is a second zone almost uniformly of the same colour. The umbilicus is whitish, wide, deep, and bears several small, indistinct, spiral, crenate riblets. The outer margin is surrounded by a coarsely crenulate carina.

It is bordered by a spiral ridge, which is indistinctly beaded. The aperture is rounded-triangular. The upper and basal margins are regularly rounded, the upper one being more curved. The columellar margin is nearly straight, slightly expanded at its upper end above the umbilicus, thickened below and forming a distinct angle with the basal margin, largely due to the ending of the umbilical ridge.

The axis has a distinct umbilicus, bordered by the columellar edge. The shell colour is whitish with nacre generally showing through, some specimens without pattern, others with broad brown or reddish flames starting from the suture and with a peripheral rim white articulated by brown streaks. The others show adapical cords and a peripheral rim articulated. The abapical cords are generally colourless, sometimes articulated.

The base of the shell is short, well rounded, marked on the posterior fourth by six, narrow, flattened, spiral bands and between these and the umbilical chink by seven additional bands of about double the width of the former. The umbilicus is covered with a white callus. The aperture is subcircular and very oblique. The outer lip is thin at the edge and thick within.

Inferiorly, the pyramidalis attaches to the pelvis in two places: the pubic symphysis and pubic crest, arising by tendinous fibers from the anterior part of the pubis and the anterior pubic ligament. Superiorly, the fleshy portion of the pyramidalis passes upward, diminishing in size as it ascends, and ends by a pointed extremity which is inserted into the linea alba, midway between the umbilicus and pubis.

A breech birth is the birth of a baby from a breech presentation, in which the baby exits the pelvis with the buttocks or feet first as opposed to the normal head-first presentation. In breech presentation, fetal heart sounds are heard just above the umbilicus. Babies are usually born head first. If the baby is in another position the birth may be complicated.

The solid shell has a depressed-conical shape. The outer surface is sharply, spirally striate and closely obliquely striated . The shell has a more or less developed callous ridge or funicle revolving on the inner side of the whorl within the umbilicus, and terminating at the columella, the edge of which is reflexed over it. The sinuous columella terminates in a point or denticle at its base.

The cancellation of the body whorl is strongly developed, so that the pittings between the cross- ridges are deep and striking. The suture is deep and channelled. The uppermost of the six revolving lirae borders the channelled suture, and the umbilicus is encompassed by a swollen ridge, which is in addition to the six line referred to. The microscopic striae are seen upon the lirae.

The height of the shell attains 1.5 mm and its diameter 4 mm. The white shell has a plane-discoidal shape with 5 whorls. The species is beautifully cancellate and sculptured, though more or less smooth below the periphery and around the narrow but deep umbilicus. The whorls are all channeled at the sutures, very distinct (seen with a lens) on the two apical whorls.

Shells medium-sized to large (diameter of base without attachments 80–160 mm; height of shell 42–100 mm), thin-shelled, with wide peripheral flange, simple or weakly digitate, porcellanous ventrally. Umbilicus narrow to wide, sometimes plugged with callus. Foreign objects attached to periphery on few to all whorls, usually small and inconspicuous, leaving most of the shell surface exposed.Kreipl, K. & Alf, A. (1999): Recent Xenophoridae.

The 1-2 × 3-6 mm shell has up to 7-8 densely coiled and rounded whorls with deep suture. The whorls are higher than wide, the lower side is almost flat, the upper side with a large umbilicus which is more than 1/3 of the shell diameter. The aperture is narrow. Shell colour is reddish horny brown, often with black or brown encrustations, finely striated.

The base of the shell is very flatly rounded with 7 concentric narrow lirae, the inner 4 closer than the rest, which are separated by 4 to 6 interlirate striae. The umbilicus is narrow, minutely axially incised. The aperture is oblique and roundly quadrate. The outer lip is slightly convex, thin, and smooth within The margin is sinuously convex below the suture, and concave towards the periphery.

The body whorl has six strong, smooth spiral keels, narrower than the intervals, which are flat and crossed by numerous retractively axial threads, which are much narrower than their intervals. Within the umbilicus, two rather small spiral cords are visible. The aperture is quite oblique and subcircular. The outer lip is strengthened by a rounded external rib or varix a short distance behind the edge.

A peripheral band is distinctly articulated with white and brown and an intermediate band of more arrow-headed blotches. The interstices are filled by the yellowish-brown lines, which are often confluent, leaving only small whitish spots. The basal surface is lighter, with scarce markings, of which a band of blotches, bordering the umbilicus, is the most conspicuous. The shell contains about five whorls.

The outer lip is thin and sharp, not at all expanded. The inner lip is thin and sharp, a very little patulous on the columella, where it also retreats a little, so as to form a slight open sinus. The shell is brilliantly iridescent within. The umbilicus is wide and pervious, and deeply impressed at the suture, which runs spirally up to the apex within.

The spiral sculpture consists of (on the spire three) strong blunt keels, of which two near the periphery are the most prominent, with subequal wide interspaces. There is a fourth less prominent one on which the suture is laid which only shows on the body whorl. On the base there are about 10 smaller cords irregularly spaced. The axis is perforate by a narrow twisted umbilicus.

These plications disappear a third of the way toward the periphery. The wall of the umbilicus is concave, overhung by the carina. The turns of the shell are so coiled that the part of each whorl uncovered by its successor forms a narrow spiral plane ascending to the apex like a spiral staircase or screw thread. The thin columella is straight and lacks a callus.

The basal margin is decidedly expanded and curved. The columella is very oblique, concave and toward the insertion, its edge scarcely reflexed, simple, bearing a single triangular projection or tooth below the middle, and terminating in a very strong, quadrate, biplicate tooth at its base. The parietal wall is wrinkled. The umbilicus penetrates deeper than the insertion of the columella and is bordered by a plicate rib.

The base of the shell is convex, eroded and white in front of the aperture. The aperture is half-circular. The outer lip is not much thickened, edged with black, beautifully iridescent within, with amethystine tints. The columella is short, obtusely subdentate at the base, expanding above into a callus, which covers the axis and the umbilicus, or leaves a slight excavation or groove.

The shell of Sphenodiscus was streamlined and lateromedially compressed with overlapping whorls and a small umbilicus. The ventral edge of the shell tends to be sharply angled. The outer surface is generally smooth in fossil specimens, although certain species at different stages of ontogenic development may possess many small tubercles along their surfaces. Sphenodiscus had a complex suture pattern with many small branching lobes and saddles.

Bredyia is a genus of ammonites from the lower part of the Middle Jurassic, found in Europe and North America. Bredyia is a member of the Hammatoceratidae, a family which comprises part of the Hildoceratoidea. Its shell is involute, strongly ribbed, with a small umbilicus. Whorls are strongly embracing; ribs thick, radially straight on the sides, curves forward on the venter but do not meet.

Their sculpture shows above the periphery six subgranose spiral ribs, elevated, widely spaced, increasing in size from the suture to the periphery and ascending the spire. The interstices are occupied by one or two spiral threads and roughened by fine radial growth lines. On the base, eight similar spiral cords decrease in size from the periphery to the umbilicus. The subquadrate aperture descends slightly but suddenly.

The small intestine develops from the midgut of the primitive gut tube. By the fifth week of embryological life, the ileum begins to grow longer at a very fast rate, forming a U-shaped fold called the primary intestinal loop. The proximal half of this loop will form the ileum. The loop grows so fast in length that it outgrows the abdomen and protrudes through the umbilicus.

The parietal callus is glossy and delicate, and has a node that projects towards the umbilicus. Juvenile individuals possess shells ornamented by spiral lines and strong cords, in contrast to the nearly smooth, homogeneous surface of mature specimens. The lusterless color pattern is rather distinct, overall white with black zigzag flammules on each whorl. Those spots have a tendency to become axial lines in older, larger individuals.

The peristome is expanded and/or reflected, and is sometimes thickened. The columella may be straight or recurved, and the parietal callus is weak to well-developed, and the umbilicus may be open or closed. The radula is spatulate, has cusped teeth arranged in rows, usually with a monocuspid central tooth and bicuspid or tricuspid lateral teeth. The jaw is thin and weak, with low flat ribs.

The aperture is rounded-subquadrate. Its right margin is incomplete, its columellar margin is curved, with a denticle in the basal part. It is slightly reflected over the umbilicus. The interior of the shell is nacreous, (the nacreous texture of the inner layers is clearly visible on some of the exterior parts, where the outer layer has been removed by accidents during the youth of the animal).

All incisions have healed well and the most visible remaining effect of surgery is from the pre-operative hair removal. Steps of a cholecystectomy, as seen through a laparoscope. The 1-week-old incisions of a post-operative laparoscopic cholecystectomy as indicated by red arrows. The 3 abdominal incisions are approximately 6mm, while the fourth incision near the umbilicus is 18mm, each closed with dissolvable sutures.

These spirals are narrow, cord-like, with large interspaces, crossed by riblets in very various direction. The umbilicus is rather large, but nearly closed by the columellar margin, leaving only a fissure. The aperture is incomplete, a rather broad but not deep fissure at the upper part, rounded and turned up behind. The shape of the aperture is subquadrangular, irregular by the terminations of the keels.

The shells sometimes feature an umbilicus. Wentletrap shells have a roundish or oval aperture, but its inner lip is often reduced to strip of callus. The round and horny operculum is paucispiral and fits the aperture tightly. Most of the species in the family are small to minute, although some are larger, and overall the adult shell length in the family varies between 0.6 and 11.7 cm.

The sculpture consists of 5 prominent spiral riblets, the first just above the periphery. There is a low and indistinct spiral riblet on the body whorl outside the suture, and sometimes a fine riblet bordering the funnel-shaped umbilicus. The radiate sculpture is formed by distinct threads, which are equidistant and slightly directed backward, with their interstices wider than the threads. The spire is depressed conoidal.

The height of the adult shell varies between 8 mm and 12 mm, its diameter between 5 mm and 7 mm. The turreted, slender, thin shell is narrowly perforate. It is shining, white, with longitudinal undulating or zigzag pinkish or purplish lines, often uniting to form spots at the periphery, or prominently angled there. Sometimes it shows spiral bands at the periphery and around the umbilicus.

Spirals—there are furrows broadish and square- cut, parted by flat raised surfaces of about twice their breadth. These extend to below the periphery, but not to the base, the most of which is smooth. Round the umbilicus is a high raised thread, which relatively to the size of the shell is enormous. The four whorls are well rounded, and a very little tabulated below the suture.

They are marked by very much enfeebled indications of axial ribs, which are best shown at the summit of the whorls, and broad low spiral lirations, of which 7 occur between the sutures. The periphery and the base of the body whorl are well rounded. They are marked by eight low spiral cords, which are somewhat closer spaced about the umbilicus. The aperture is oval.

The peripheral groove is about equal in width to the one anterior to the posterior keel. The entire shell is marked by fine, sublamellar, regularly spaced, retractive axial ribs, which render the spiral keels somewhat crenulated at their meeting points and break the spaces between them into small squares or oblongs. These riblets extend from the sutures to the small umbilicus. The aperture is subovate.

Paracymbites is an extinct genus of lower Jurassic ammonite that lived during Raricostatum zone of upper Sinemurian. Animals belonging to this genus had small shells with semicircular whorl section and rounded or fastigate venter, of which umbilicus made about 25% of diameter. Last whorl could have been excentric. Keel was faint and it might have been only on the earlier part of the last whorl.

The outer lip is thin. The base of the shell is quite short, rounded, and lacking an umbilicus. The columellar tooth is conspicuous and in a rather high position on the columella.J.J. van Aartsen, E. Gittenberger & J. Goud, Pyramidellidae (Mollusca, Gastropoda, Heterobranchia) collected during the Dutch CANCAP and MAURITANIA expeditions in the south-eastern part of the North Atlantic Ocean (part 1); CANCAP-project .

The base is conical, excavated just within the peripheral carina. It rises to the edge of the umbilicus, which is marked by a strong thread, and within is vertically striated. The body whorl descends from the general plane, and finally becomes separated from the body whorl. The simple margin is sharply angulated by the carinations, otherwise the aperture would be ovate, with the columellar side somewhat excavated.

The shell has a flattened globular shape, and reaches about in maximum dimension. The color of the shell is variable, but is often a greyish brown. The central apex of the shell is often a dark blue in fresh shells, which can make the shell somewhat resemble an eye. On the underside, there is a large brown callus which partly blocks the umbilicus of the shell.

Uchtites is a genus of ammonoid cephalopods included in the anarcestid family Acanthoclymediidae that lived during the Devonian period. Its shell is lenticular, flat sided, with a tight umbilicus and sharp ventral keel bordered by weak nodules in adult specimens. The suture has a trifid ventral, rounded outer lateral, weak rounded inner lateral and wedge shaped dorsal lobe. Acanthoclymenia, Gogocers, Nordiceras, and Ponticeras are related genera.

During the fourth week of human embryonic development, the lateral body wall folds of the embryo meet at the midline and fuse together to form the anterior body wall. However, in gastroschisis and other anterior body wall defects, this fails to occur by either one or both of the lateral body wall folds not moving properly to meet with the other and fusing together. This incomplete fusion results in a defect that allows abdominal organs to protrude through the abdominal wall, and the intestines typically herniate through the rectus abdominis muscle, lying to the right of the umbilicus. The forces responsible for the movement of the lateral body wall folds are poorly understood, and a better understanding of these forces would help to explain why gastroschisis occurs mostly to the right of the umbilicus, while other ventral body wall defects occur in the midline.

In the fetus, the internal iliac artery is twice as large as the external iliac, and is the direct continuation of the common iliac. It ascends along the side of the bladder, and runs upward on the back of the anterior wall of the abdomen to the umbilicus, converging toward its fellow of the opposite side. Having passed through the umbilical opening, the two arteries, now termed umbilical, enter the umbilical cord, where they are coiled around the umbilical vein, and ultimately ramify in the placenta. At birth, when the placental circulation ceases, the pelvic portion only of the umbilical artery remains patent gives rise to the superior vesical artery (or arteries) of the adult; the remainder of the vessel is converted into a solid fibrous cord, the medial umbilical ligament (otherwise known as the obliterated hypogastric artery) which extends from the pelvis to the umbilicus.

Blood usually oozes from the forehead, nails, umbilicus, and other skin surfaces. In addition, oozing from mucocutaneous surfaces causing nosebleeds, bloodstained tears, and vicarious menstruation are common. The episodes may be preceded by intense headache and abdominal pain and are usually self-limiting. In some conditions, the secreted fluid is more dilute and appears to be blood-tinged, while others may have darker bright red secretions resembling blood.

The umbilical side is convex with radial depressed sutures and a wide umbilicus containing portici (asymmetrical apertural flaps) and tegilla (umbilical coverings). A distinct peripheral keel runs along the edge of the spiral side while the periphery on the umbilical side may have an incompletely developed keel formed by pustules. Early chambers are globular, later ones rhomboidal in section. The wall is calcareous, perforate and pustulate, especially on the umbilical side.

This is just behind the Umbilicus UrbiHülsen, Op. cit. and the (future) New Rostra (Rostra Augusti).Richardson, Jr., L. (1992), A New Topographical Dictionary of Ancient Rome, Baltimore and London: The Johns Hopkins University Press, pg 432. Boni uncovered a small shrine here that had been cut directly out of the natural tufa and had tufa blocks defining a precinct area (identified from literary sources as the Area VolcaniHülsen, Op. cit.).

2004) and has been found in Upper Devonian sediments in Germany and Poland (Miller et al. ibid) Exotornoceras is the ancestral tornoceratid, named by Becker in 1993. Exotornoceras is derived from Gundolficeras( Falcitornoceratinae) Discoclymenia is the type of the Discoclylemniinae, named by Hyatt in 1844. Discoclymenia has a subglobular to discoidal shell with a small, closed umbilicus, like Sporadoceras but with additional adventitious lobes in the 1st lateral saddles.

The intercostal spaces about as wide as the ribs. They are marked by seven equal and equally spaced spiral pits. The periphery and the base of the body whorl are well rounded, the latter marked by the continuations of the axial ribs and eight equally spaced series of spiral pits, of which those nearest the umbilicus are a little less strongly developed than the rest. The oval aperture is moderately large.

Cooperoceras is a genus of Tainoceratid nautiloid cephalopod molluscs within the superfamily Tainocerataceae, characterized by and evolute shell with an open, perforate, umbilicus, sinuous ribs at maturity, and recurved hollow spines along the ventro-lateral shoulders. The flanks and venter are flattened, the flanks converge on the dorsum, the venter has a shallow median groove. The suture is with rounded ventral and lateral lobes. The siphuncle is small, tubular, and subcentral.

There is a large flat variety. The commonest variety is white with three spiral bands one near the suture, one above and one beneath the periphery. But some shells have the ground-colour brownish with darker bands, and some are white or dark brown throughout. The parietal wall of the aperture and the area around the umbilicus are never darker than the adjacent portion of the last whorl.

The length of the white shell reaches 2.5 mm. The shell has a depressedly globose shape. It is strongly sculptured, with a rather high scalar spire, exserted whorls, a very sharp and expressed carina, a minute tabulated apex, a strong and impressed suture, a tumid base, and a large pervious but half covered umbilicus. The radiating ribs are pretty strong, sharp, and equal above and below the canal.

This body whorl is nearly smooth, except for most tender spiral and radiating striae, only visible under magnification, and a few remote deeper striae near the suture, being the continuation of the beads. It is strongly depressed, more convex above than below, with a blunt angle, but no keel. The umbilicus is funnel-shaped, moderately wide and pervious. Its walls are smooth, with only a few growth striae.

The columella is very oblique, slightly tortuous above and enters very deeply, terminating below in a strong plicate tooth, and with a smooth margin, save for a small denticle immediately above the basal tooth. The parietal tract is wrinkled. The umbilicus has a plicate-denticulate border. In the typical form, the 1st, 3d, 5th, 7th and 9th lirae, and one or two upon the base are articulated with black.

The shell is small, of a yellowish green- color, minutely wrinkled by the lines of growth. The spire is flat, composed of 2.5-3 whorls, separated by a well-defined suture. The outer whorl has a sharp margin on a level with the spire, diminishing near, but still modifying, the aperture. Below this line the whorl is very convexly rounded so as to encircle a small, deep, abruptly formed umbilicus.

The basal lip is convex, slightly effuse, and smooth within. The upper third of the columella is concave, the rest is straight, and obliquely truncate below. The callus at the base partly borders the umbilicus and is attached to the columella along a vertical groove. The shell is purple-brown, with somewhat oblique, axial, creamy, rhomboidal flames, extending from suture to suture, and nearly equalling the foundation colour in area.

The 10–25 × 6–12 mm shell is slender with the whorls often not very convex and nearly always with flat sutures. It is brown, irregularly striated (surface ornamented with strong spiral striae which cross-cut the radial growth striae – this can lead to the development of quadrate plates) and the apertural height is about 50% of the shell height. The umbilicus is closed.Species summary for Stagnicola fuscus.

The body whorl goes slightly down to the aperture. The surface is smooth, except for the base of the body whorl, which has, seen from the periphery, low concentric striae, that disappear at a considerable distance from the umbilicus. The circular aperture has a continuous peristome. The columella has a thick, narrow callus that hardly reflects on the umbilical opening in young specimens but cover it completely in adults.

The outer lip is not thin, and has a slight callus just within it. It is slightly sinuated on the base at the outer corner. The columellar lip on leaving the body, bends over very flatly so as to cover the umbilicus, after which it curves round to the left. It has a very blunt tubercle in the middle, is a little reverted, and has a very slight furrow behind it.

Permonautilus is an extinct genus of nautilids from the Upper Permian of Russia, named and described by Kruglov in 1933. Permonautilus is an involute, globular, spinose member of the Lirocertidae which are included in the Clydonautilaceae. Whorl sections are broad, with a rounded venter. The umbilicus in the middle of the shell is deep, from which spine-like processes extend laterally in the mature portion near the aperture.

The body whorl is obtuse at the periphery, nearly flat below, indented around the false umbilicus, obsoletely concentrically lirate, the lirae about 9 in number, red and white articulated, interstices white. The aperture is transversely rhomboidal, somewhat rounded. The columella is nearly vertically descending, subdentate at base, above with a profoundly entering spiral fold. The parietal wall bears a heavy transparent callus, which is excavated around the axis.

The outer whorl is coiled over these so that the whorl inside only touches the outer one by these prominences. They are not continuous over the base, but within the ample umbilicus are two rows of small prominences corresponding in number to those on the periphery. The circular aperture has a complete circular varix which is radiately crenulated. The apex is sunk below the top of the body whorl.

For terms see gastropod shell The shell is very small, 1.2-1.6 mm in width.(Welter-Schultes) The 0.6-0.8 x 1.2-1.6 mm shell is almost flat, extremely densely and regularly striated, appearing silky shiny light horny brown. There are 3-3.5 moderately convex whorls, the aperture is rounded, with a thin margin which is not reflected and without a lip. The umbilicus is wide (25% of shell diameter).

The back as a general area is the dorsum or dorsal area, and the lower back is the lumbus or lumbar region. The shoulder blades are the scapular area and the breastbone is the sternal region. The abdominal area is the region between the chest and the pelvis. The breast is also called the mammary region, the armpit as the axilla and axillary, and the navel as the umbilicus and umbilical.

This peritoneal inflammation, or peritonitis, results in rebound tenderness (pain upon removal of pressure rather than application of pressure). In particular, it presents at McBurney's point, 1/3 of the way along a line drawn from the anterior superior iliac spine to the umbilicus. Typically, point (skin) pain is not present until the parietal peritoneum is inflamed, as well. Fever and an immune system response are also characteristic of appendicitis.

Dorsetensia is a narrowly coiled discoidal ammonite from the early Middle Jurassic, lower Bajocian, belonging to the family Sonniniidae of the superfamily Hildoceratoidea. The inner whorls are ribbed or smooth, outer whorl is smooth. The outer rim (venter) is narrow, with a keel running along the middle. The umbilicus, the opening in the middle of the shell exposing inner whorls, is of moderate size with a sharp, sometimes undercut edge.

Oxycerites is an extinct ammonoid cephalopod belonging to the haploceratoid family, Oppeliidae, that lived during the Middle Jurassic. Shells of Oxycerites are involute, compressed and generally smooth with a sharply rounded venter on the outer rim, deeply impressed dorsum on the inner rim, and a small umbilicus. The living chamber takes up slightly more than half a whorl. Oxycerites grew to a diameter of at least 17.5 cm, about 7 inches.

The periphery is acutely carinated, bearing numerous short compressed triangular radiating spines. The flat base of the shell is densely radiateiy lamellose-striate, with a strong rib revolving midway between the periphery and the center The aperture is oblique, pearly white within, transversely ovate, deeply channelled at the periphery. The columellar region is white, strongly bicostate, deeply excavated at the position of the umbilicus. The parietal callus is not much extended.

The shell is coiled dextrally (i.e. clockwise). The thin, double-walled keel of the shell extends outward from the last shell whorl. The apex of the shell is found on the right side, the umbilicus on the left side. The shell and keel can be calcareous (genus Atlanta), or composed exclusively of conchiolin (genus Oxygyrus), or the shell can be calcareous and its keel composed of conchiolin (genus Protatlanta).

Radstockiceras is an extinct genus of lower Jurassic ammonite that lived from Oxynotum zone of upper Sinemurian to Raricostatum zone of lower Pliensbachian. Shells of these animals were oxycone and involute with umbilicus that took maximum of 12% of diameter in the case of outer whorls. On inner whorls, venter has been sharp, but then it became rounded. Faint ribs had falcoid shape, but sometimes, ribs could absent.

One of the largest gastropod shells found on the Southern California coast, this species varies between 40 mm and 145 mm. The shell lacks an umbilicus, and has a turbinate-conical shape. Like other shells of the family turbinidae it is composed of a thick inner nacreous layer, covered by a thinner porcellanous layer. In this species both are covered by a dark brown shaggy periostracum in life.

The aperture is suboval to ovate with the peristome incomplete behind. There is usually a tooth-like fold on the columella. The shells usually have a small umbilicus or none at all. Macgillivray, William , History of the molluscous animals of Scotland; London, 1844Rachel Collin & John B. Wise (1996), Morphology and development of Odostomia columbiana Dall & Bartsch, 1909 (Pyramidellidae); Implications for the Evolution of gastropod Development, Biol. Bull. 192: 243-252.

The shell resembles a miniature Nautilus, with greatly overlapping, rounded whorls, in which the last whorl completely encompasses the others, leaving either a very narrow umbilicus on either side, or none at all. At the aperture of the shell is a slit, which results in a sort of low ridge that runs along the length of shell. The shell has a low profile and these possibly were active, fast-moving molluscs.

Henry Augustus Pilsbry created what was then the subgenus Appalachina (under the genus Mesodon), a group of land snails in the family Polygyridae, for those snails with comparatively depressed (flat) shells and an open umbilicus (the center of the underside of the shell). The reproductive anatomy of these snails is important for distinguishing them from other polygyrids.Pilsbry, Henry A. (1940). Land Mollusca of North America (North of Mexico). Acad. Nat. Sci.

The shell is solid, unicolored light ochre, biconcave, irregularly striated according to some growth lines, with numerous hair pits covering the whole surface. The spire is deeply sunken. The shell has 3¾-4½ whorls. Whorls are rounded, first whorls very narrow, the last one very large, and partly embracing the preceding one, distinctly descending in front. The umbilicus is deep, and about 1/8 of the width of the shell.

Uraloclymenia is an extinct ammonoid cephalopod genus from the Late Devonian, Famennian stage. The type species is Uraloclymenia volkovi Bogoslovskii, 1977 The shell of Uranloclymenia is lenticular, with a narrow umbilicus and usually free of ribs. Constrictions are absent. The suture has a very broad, shallow ventral lobe, a shallowly rounded lateral lobe, an inconspicuous umbilical lobe inside the umbilical seam, and an internal lobe on the dorsum.

There are 4.5-6 weakly convex whorls with weak suture. The last whorl width is 1.5 x or less of the preceding whorl which is well rounded at lower side. The umbilicus is not very wide, 1/8-1/7 of diameter. Genitalia: internal ornamentation of proximal penis consisting of more than seven longitudinal pleats, sometimes straight and distinct, sometimes wavy, slender and connected by lateral projections giving a reticulate appearance.

The umbilical ring is a dense fibrous ring surrounding the umbilicus at birth. At about the sixth week of embryological development, the midgut herniates through the umbilical ring; six weeks later it returns to the abdominal cavity and rotates around the superior mesenteric artery. Dense embryonic connective tissue encircles the attachment of the umbilical cord. It forms an umbilical ring of mesodermal condensation surrounding the coelomic portal, and is present in the 16 mm.

Liroceras is a genus of nautiloid cephalopod. It is the type genus of the clydonautiliacean family, Liroceratidae, and is characterized by a rapidly expanding, subglobular, nautiliconic shell with a reniform whorl section, small umbilicus, essentially straight sutures, and a siphuncle with a variable but not marginal position.Bernhard Kummel, 1964. Nautiloidea-Nautilida; Treatise on Invertebrate Paleontology, Part K. Geol Soc of America and Univ of Kansas Press, R. C. Moore (ed) — Liroceratidae K444–K447.

Of these spirals there are about seventeen on the body whorl, much closer set and less uniform than the ribs. In particular the carinal spiral, which is very sharp, and the fourth and seventh above it, are stronger than the others. The last mentioned of these is especially so on the earliest whorls. On the base the longitudinals though continued even into the umbilicus, become much less prominent and are no longer nodose.

The ventral lobe is divided, 1st lateral lobe is larger than the second, which is followed by a series of auxiliary lobes decreasing in size toward the umbilicus. J.P Smith, 1932, included Sturia in the Thalassoceratidae, but only tentatively. The American Treatise on Invertebrate Paleontology, Part L, 1957, includes Sturia in the Ptychitidae, along with such genera as Ptychites, Discoptychites, Aristoptychites, and Parasturia. Sturia is now included in the Sturiidae, established by Kipsarova.

Paratornoceratinae is a subfamily of oxyconic dimeroceratids included in the order Goniatitida, a group of Paleozoic ammonoids, which have closer affinity to living coleoids than to Nautilus. Paratornoceratinae as defined by Ebbighausen, Becker, & Bockwinkel in 2002 comprises three recognised genera with sharp, oxyconic, venters; Acrimeroceras, Paratornoceras, and Polonites. The shell, as described for the type, Paratornoceras, is subglobular and evolute on young stages, but discoidal and with closed umbilicus in the adult.

Texoceras is an extinct ammonoid genus in the monotypic goniatitid subfamily Texoceratinae, included in the family Adrianitidae. These are shelled cephalopods more closely related to squids, belemnites, octopuses, and cuttlefish than to nautiloids from which they are derived. Texoceras, named and described by Miller & Furnish in 1937, has an involute, subglobular shell, like Adrianites, with a narrow, deep umbilicus in the middle, but with a reticulate surface and a suture that forms 14 rounded lobes.

The shells of juveniles are sharply keeled, however the keel is not present on the final adult whorl. The aperture often has a lip that is light reddish on the inside, and the lip margin is only reflected at columellar side. The umbilicus is narrow and half covered by the reflected columellar margin. The apex has a characteristic size in the eastern Mediterranean when compared with other species, where there are no other Theba species.

Gundolficeras is member of the Tornoceratidae, (goniatitid ammonites), from the Late Devonian named by Becker, 1995 and assigned to the Falcitornoceratinae. The type species is "Lobotornoceras" bicaniculatum. Gundolficeras has a compressed or somewhat inflated shell that may have ventrolateral furrows and an open or closed umbilicus at medium stages. The suture has a small ventral lobe and on either side, a narrow, asymmetric, rounded or pointed adventitious lobe and a high saddle located mid-flank.

An undescended testicle is unlikely to spontaneously resolve after 6 months and, thus, orchiopexy is usually performed before the age of one year. The undescended testicle may be located within the normal line of descent (for example, in the inguinal canal) or high in the scrotum or ectopically (i.e. the abdomen). The surgeon may use an endoscope through the umbilicus to locate the testicle, and through other small opening(s) performs the procedure.

Carinonautilus is a genus of extinct, Middle Cretaceous nautilid with a very involute, compressed shell in which the whorl section is higher than wide, umbilicus is small and shallow, or flanks converge on a narrow venter that has a rounded keel. A furrow on either side marks the ventro-lateral shoulder. The genus was erected by Spengler in 1910 on the basis of the holotype, found in Middle Cretaceous strata from India.

The siphuncle is subcentral. The surface is ornamented with fine lirae. Syringoceras,Kummel, 1964, K440 found in Europe, on the island of Timur in Indonesia, and in western North America (Calif and Nev) is like Syringonautilus except that the siphuncle is near marginal. Clymenonautilus,Kummel, 1964, K439 first of the strictly Upper Triassic genera, is evolute with a perforate umbilicus and deep dorsal impression when the whorl envelops a third of the previous.

The sand collar egg mass of Euspira catena The rounded shell is thin and polished and brownish-yellow, with a row of reddish markings just below the suture of the last whorl. It can grow to about and has a short spire and seven rounded whorls separated with distinct sutures. The lowest whorl occupies about 90% of the volume. It has a large umbilicus and the operculum is ear-shaped and spirally wound.

Its upper insertion is carried far forward, connected with the lower by a thin dull film of callus. The lip is quite sharp, within a white edge is followed by a brown border anfl that again by a nacreous layer. This sequence again appears along the interior suture. The umbilicus forms a broad open funnel, penetrating to the initial whorl, margined by a beaded funicle which ends in an expansion on the columella base.

In human anatomy, superior epigastric artery refers to a blood vessel that carries oxygenated blood and arises from the internal thoracic artery (referred to as the internal mammary artery in the accompanying diagram). It anastomoses with the inferior epigastric artery at the umbilicus and supplies the anterior part of the abdominal wall and some of the diaphragm. Along its course, it is accompanied by a similarly named vein, the superior epigastric vein.

Like other species of the genus, the shell of S. neglecta is a little flatter than spherical, pale brown in colour with a chestnut peripheral band. Distinctive features of the shell are its relatively small size (15–17 mm diameter, c. 9 mm high), an umbilicus about a seventh of the diameter, and the surface sculpture of the protoconch. The type specimen is now in the Natural History Museum of Los Angeles County (LACM 1451).

The outer lip is more curved and more finely crenulate within than that of Monodonta labio. The columella is short, squarely dentate at its base. Its edge is more or less rugose, and separated from the columellar area by a deep narrow straight sulcus, extending from the place of the umbilicus to the notch at base of columella. The basal notch is deep and divided by a small denticle in the middle.

The crenelations round the half-covered umbilicus are large in proportion to the size of the shell. The aperture is round. The peristome is continuous, hardly thickened, a tongue- shaped process, lirato-sulcate as is the rest of the surface, extending over the umbilical region.Melvill (1904) Descriptions of 28 species of Gastropoda from the Persian Gulf, the Gulf of Oman and the Arabian Sea; Proceedings of the Malacological Society of London v.

Intestinal atresia can occur, which is where the mucosa and submucosa of the intestine form a web that obstructs the lumen which leads to malabsorption. Obstruction of the bowel can occur which results in short bowel syndrome. For the first few years of life there is a high incidence of gastroesophageal reflux which can be complicated by oesophagitis. Post-surgery the umbilicus (navel) is deficient or abnormally placed that causes dislike amongst many patients.

Also in 1893, the British Medical Journal published a report about their physical state, finding them "free from all element of repulsiveness" and "apparently perfect in every respect, except that from the ensiform cartilage to the umbilicus they are united together.""The Orissa Twin Sisters" British Medical Journal 1(June 1893): 1176. Another medical journal reported that "the children seldom quarrel"."The Orissa Twins" The Phrenological Journal and Science of Health (January 1894): 33.

The shell is rather depressed, with dome-shaped spire, the periphery mainly rounded but indistinctly subangular in front of the aperture, the base rather strongly convex. The umbilicus is small, widened in the last half-whorl, contained about 5½ times in the diameter of shell (in some examples smaller, 6 times or 7½ times in diameter). Opaque, cinnamon-brown, without much gloss, smoothish, with low growth-wrinkles. Whorls are strongly convex and increase slowly.

The aperture is higher than wide, slightly oblique and quadrangular. The umbilicus is very deep, rather cylindrical, bordered by a deeply crenated white marginal rib, with a narrower beaded cingulus just outside it. This is a compact, depressed little shell, with diamond-shaped aperture, showing in fresh specimens a slight trace of pearl within. Adams describes the color as spotted with brown in transverse series, with transverse whitish lines, and a wide subsutural white band.

The narrow umbilicus is profound. The slightly elevated, rather narrow, transverse striae are crowded, blunt, and very unequal above, on the base rather regular and elevated. The striae number 4 on the penultimate whorl, about 6 above the periphery of the body whorl, with here and there an intermediate smaller one, and upon the base 10 less elevated ones. The interstices look pitted on account of the elevated incremental striae that cross them.

It is ornamented upon the ribs, with alternate white and red spots, often also orange, which, disposed thus in regular series, present a beautiful appearance. The aperture is very large, colored within of a chestnut tint. The outer lip is thin, notched, canaliculated within, and its edge is white and undulated. The inner lip is only slightly perceptible towards the base, where it forms a part of the umbilicus, which is hardly developed.

The inner edge is bevelled, of a dull callus, radiately plicate, the margins united by a thick layer of callus, within brilliantly nacreous. An expansion of the columella slightly intrudes upon the umbilicus, which is narrow but deep, margined by a crenulate rib, internally with two deep-seated funicles. Charles Hedley, The Mollusca of Mast Head Reef, Capricorn Group, Queensland. Part II; Proceedings of the Linnean Society of New South Wales v.

An umbilical hernia is also a defect in which abdominal contents come through weak abdominal wall muscle at the umbilicus. In general, newborns with umbilical hernias do not require treatment because often these hernias spontaneously close by age four. If, after this time, a hernia is still present, surgery may be recommended. Diastasis recti is a separation of the left and right sides of the rectus abdominis muscle that are normally joined together.

The aperture is rounded, slightly angular above and stronger so below. The outer margin is thin and regularly curved The columellar margin is concave, reflected over the small umbilicus, angular near the base, where it joins the basal margin, and slightly protracted there. The thin operculum is horny, with few whorls, and concave at the outer side. The radula has scarcely the length of 1 mm, and is about ⅓ mm in breadth.

The 14 whorls show a very regular increase. They are very slightly convex, sharply acute-angled at the carina. The base of the shell is flat at the outer edge and barely convex in the middle, with a slight dip in toward the edge of the umbilicus which is strongly defined. The suture is linear, defined by the white carinal fillet, and also on the lower whorls by being very slightly impressed.

Moreover, these interstices are filled with similar finer spirals as in the spire. The funnel-shaped umbilicus is moderately wide, and probably pervious. Its wall shows fine radiating striae and a conspicuous spiral groove, terminating in a strong dentiform projection on the columellar margin. The aperture is moderately large, irregular in shape, with a rather deep sinus at the suture (about 1½ mm, behind the most projecting part of the outer margin).

Bradfordia is a moderately involute to involute genus included in the ammonoid cephalopod family Oppeliidae, coiled so that the outer whorl encloses most, or much, of the previous, but with a small umbilicus exposing inner whorls. The shell is compressed, whorl height much greater than width, extending well out from the contact with the adjacent inner whorl. Outer flanks are finely ribbed and the rounded venter is smooth. Bradfordia lived during the Middle Jurassic.

Symptoms may differ greatly, as apparently modifiers control to some degree the amount of FVII that is produced. Some affected individuals have few or no symptoms while others may experience life-threatening bleeding. Typically this bleeding disorder manifests itself as a tendency to easy bruising, nose bleeding, heavy and prolonged menstruation, and excessive bleeding after dental or surgical interventions. Newborns may bleed in the head, from the umbilicus, or excessively after circumcision.

The periphery and the base are well rounded, the latter broadly umbilicated and marked by 10 depressed spiral cords which are truncated posteriorly and slope gently anteriorly. The whole has the appearance of a series of imbricating bands. In addition to these, there are three cords in the umbilicus wider and stronger than those on the base. These cords are crossed by closely spaced riblets which give them a peculiarly notched appearance.

In medicine, the Sister Mary Joseph nodule or more commonly node, also called Sister Mary Joseph sign, refers to a palpable nodule bulging into the umbilicus as a result of metastasis of a malignant cancer in the pelvis or abdomen. Sister Mary Joseph nodules can be painful to palpation. A periumbilical mass is not always a Sister Mary Joseph nodule. Other conditions that can cause a palpable periumbilical mass include umbilical hernia, infection, and endometriosis.

The five post-nuclear whorls are slightly rounded, somewhat constricted at the summit. They are marked by almost vertical lines of growth and very regular, closely spaced, wavy, spiral striations; of the latter about 25 occur between the sutures and the third whorl. The periphery of the body whorl is decidedly inflated and strongly rounded. The base of the shell is moderately long, well rounded, with a narrow umbilicus, marked like the spire.

The base is concentrically, rather deeply furrowed, the 6 furrows narrower than the intervening ridges. In the umbilicus, which perforates almost to the apex, all of the whorls are visible, encircled by an acute carina. The aperture is subquadrate, nacreous, smooth within, and has a groove indicating the place of the external keel. The columella is S-shaped, and ends in a blunt tooth, before which there is a small acute denticle.

The base of the shell is convex and concentrically lirate. The aperture is oblique. The columella is strongly dentate in the middle or below it, with a second small tooth at the base. The edge of the columella is rather deeply curved above the tooth, but spreading at its junction with the whorl, bounding and somewhat narrowing the umbilicus by a white callus, which does not extend to the upper margin of the aperture.

It is characterized by its small size (13 mm), spindle-shape, whitish colour and smooth surface. The height of the shell is up to 13.4 mm, three times as long as wide, rimate, spindle-shaped, with slightly convex sides, rather thin. Colour is uniformly greyish-whitish or with axial streaks of light to dark-brown, the upper whorls somewhat darker; a dark band around the rimate umbilicus. Surface is hardly shining, with incrassate growth striae.

The outer lip, terminated by a scolloped dilatation, is traversed by a canal of no great depth. The inner lip is white, thin, applied to the body of the body whorl and forms a part of the umbilicus. The columella is twisted spirally. The coloring of the exterior is whitish, varied with red, and covered, upon the transverse ribs, with irregular spots which sometimes form longitudinal or zigzag bands of a deeper color.

From the base juts out a round fold, which is seen to turn in a spiral manner in the umbilicus. The ovate operculum is membranous, its laminae not spiral, having one or two notches to receive the folds of the columella.Kiener (1840). General species and iconography of recent shells : comprising the Massena Museum, the collection of Lamarck, the collection of the Museum of Natural History, and the recent discoveries of travellers; Boston :W.

The umbilicus is bordered by a row of coarse, compressed beads, 17 in number. The space between the basal and the umbilical keel contains 5 smooth lirae. The lower whorls have a distinct, nearly horizontal space, from the suture towards the upper keel, with small, radiating plicae, corresponding to the nodules. The spaces above and below the peripheral keel are slightly concave, the suture laying by this construction in a sort of canal.

Umbilicus scmidtii is a western hygrophyte occurring on Santo Antão, São Nicolau,Endemic plants of São Nicolau Santiago and Fogo of the Cape Verde Islands. It is confined to small areas in the subhumid and humid zones, mainly between 800 m and 1600 m. The lower most records are 550 m on Fogo (Monte Palha, leg. Killian & Leyens) and at 600 m on Santo Antao (Sunding 1981) and the uppermost one at 2000 m on Fogo (Ormonde 1977).

The whole base is covered with rather regular, riblike striae and very fine microscopic ones, visible also on the upper part of the shell. The large umbilicus occupies from the base of the columella to the opposite side, about 2/5 of the diameter of the shell It is funnel-shaped, and pervious. Its wall is spirally striate, with a single, spiral, beaded rib and radiating plicae. The thin aperture is rhombic, probably not quite developed.

The part of the urogenital sinus related to the bladder and urethra absorbs the ends of the Wolffian ducts and the associated ends of the renal diverticula. This gives rise to the trigone of the bladder and part of the prostatic urethra. The remainder of this part of the urogenital sinus forms the body of the bladder and part of the prostatic urethra. The apex of the bladder stretches and is connected to the umbilicus as a narrow canal.

It can involve the urinary bladder, but is not bladder cancer in the usual sense. Urachal cancer can occur at any site along the urachal tract. Urachal cancer was mentioned by Hue and Jacquin in 1863 followed by an elaborate work by T. Cullen in 1916 about diseases of the umbilicus, while C. Begg further characterized urachal cancer in the 1930s. Detailed diagnostic and staging schemes were proposed by Sheldon et al in 1984, which remain widely used today.

In the course of the round ligament of liver, small veins (paraumbilical) are found which establish an anastomosis between the veins of the anterior abdominal wall and the hepatic portal, hypogastric, and iliac veins. The best marked of these small veins is one which commences at the umbilicus and runs backward and upward in, or on the surface of, the round ligament (ligamentum teres) between the layers of the falciform ligament to end in the left portal vein.

Location of McBurney's point (1), located two thirds the distance from the umbilicus (2) to the right anterior superior iliac spine (3) The presentation of acute appendicitis includes abdominal pain, nausea, vomiting, and fever. As the appendix becomes more swollen and inflamed, it begins to irritate the adjoining abdominal wall. This leads to the localization of the pain to the right lower quadrant. This classic migration of pain may not be seen in children under three years.

Five genera are described in the Treatise, Syringonautilus, Clymenonautilus, Juvavionautilus, Oxynautilus, and Syringoceras. Syringonautilus and Syringoceras are known from both the Middle and Upper Triassic; Clymenonautilus, Juvavionautilus, and Oxynautilus only from the Upper Triassic.Kummel, 1964, K439-440 Syringonautilus,Kummel, 1964, K438 which has been found in the Alps, on Spitsbergen, in India and Japan has a rapidly expanding evolute shell with a perforate umbilicus and suboval whorl section. The suture has a faint ventral saddle and shallow lateral lobes.

PDF (Original description W.H. Dall) Shell in general features recalling Gaza daedala, much of whose description would apply with little change to this species. The eight whorls are in the adult roundly shouldered below the suture, rounded at the periphery, somewhat flattened on the base, and deeply and widely umbilicated. The umbilicus is a little more than half covered by a nacreous callus. The first 2½ whorls are transparent, not nacreous, very obtuse with the nucleus not prominent.

The region near the suture is almost smooth. The suture is very distinct, but not channelled. The umbilicus is bordered by an edge from which the flattened base falls away, and with straight walls forming an almost perfect cone. The body whorl is contracted just before the reflected lip, which, above, rounds out in advance of its junction with the suture, the last 6.3 mm of which descends on the whorl, giving the aperture a downward look.

Those on the upper surface show a fine spiral thread in the interstices, which are of about the same width as the riblets. The cinguli on the outer side of the base are finer and closer together. On the inner side 3 broad slightly crenulated ribs surround the umbilicus, which is also prominently spirally ribbed. The 2 cinguli below the suture are crossed and beaded by strong and sharp equidistant radiate riblets, dividing the interstices into regular squares.

The original description (Adams, 1860) reads: Testa ovata, tenuis, umbilicata, superficie cancellata; spira producta, apice obtuso. Apertura elongata, antice producta et integra; labio tenui, simplici; labro postice angulato, in medio recto, margine acuto. This genus nearly resembles Actaeon, but without any fold on the columella; the umbilicus, moreover, is wide and deep, and the surface of the shell is cancellated. The other lip forms an angle posteriorly with the last whorl, and is straight in the middle.

Plutarch linked the Roman mundus to the religious center of the city of Rome, the umbilicus urbis Romae. One such stone covered the mundus Cereris, a pit thought to contain an entrance to the underworld. Most cities of Latium and Etruria contained a similar pit or ditch; Plutarch describes the custom of a mundus as being of Etruscan origin, and states that it was used as a place where first-fruits were deposited.Plutarch, Life of Romulus ch. 11.

The insect concerned (Andricus quercuscalicis) came from the continent to Devon via the Channel Islands. Large numbers of knopper galls were sent from Woodway for research purposes in the late 1970s when the infestation first struck (Griffith 2006). A feature of the old hedge forming a boundary by the garage was the pennywort (Umbilicus rupestris) a typical plant of Devon country lanes. The winter heliotrope is a distinctive weed species and lady's smock is an early spring flower.

The aperture is oblique, and contracted by a simple, rather compressed fold at the foot of the columella, and another near the upper end of the outer lip with several small folds between them. The columella is contorted above and enters deeply the false umbilicus, the margin of which is toothed. The parietal callus is strongly plicate.Pilsbry (1901), New Mollusca from Japan, the Loo Choo Islands, Formosa and the Philippines There is a subspecies Clanculus gemmulifer var.

The nearly square aperture is very little oblique in the line of its advance, but standing out a little obliquely to the axis of the shell. The outer lip is thin, not descending. The columellar lip is thin, spread out broadly at its base over the umbilicus, which it largely conceals, with a deep narrow furrow behind it. It advances thin and pointed, curving over to the right to its angular junction with the basal lip.

The periphery of the body whorl is angulated. It is crossed by the continuations of the ribs, which disappear as they pass on to the short and well-rounded base. The base of the shell is marked by 13 continuous incised spiral lines of about equal strength which are much more closely spaced near the umbilicus than the periphery. The distance between the succeeding striations diminish in regular ratio from the periphery to the umbilical area.

The aperture is subquadrangular, inside slightly pearly.. The outer and basal lip are slightly convex, forming an acute angle at their junction. The columella is slightly oblique, with a distinct fold above, rounded, and smooth. The false umbilicus is not very deep, and has a strong spiral fold, which is sometimes distinctly grooved, thus having the appearance of two spiral ribs lying close together. Suter H. (1913-1915), Manual of New Zealand Mollusca; Wellington, N. Z. :J.

The axial sculpture consists of many protractively flexuous extremely fine lines with wider interspaces over all the whorls. The cemented edges at the suture by their opacity look like a presutural band, but this is not reflected in the sculpture. The spiral sculpture on the spire consists of almost microscopic close striae. On the base there are about a dozen fine spiral grooves between the edge of the umbilicus and the periphery, a little coarser near the carina.

These riblets then suddenly disappear, only very fine striae succeeding them, being scarcely perceptible on the body whorl, which is bicarinate. A third keel borders the flattened base;. The suture is rather conspicuous but shallow, with very slight traces of being margined, probably by the covered keel. The base of the shell shows 7 spirals of which the distal one, separated from the third keel by a slightly concave space, and one bordering the umbilicus are stronger.

The intermediate space on the base is marked with eight to ten impressed spiral striae. The interstices of the spirals are crossed by longitudinals, which are regular, fine, hair-like, but distinct and well parted. Their curve on the surface below the suture shows the old sinus. On the base they are radiating and are crowded and irregular, except round the umbilicus, where in the first two or three striae they are very sharp and distinct.

Symptoms may differ greatly, as apparently modifiers control to some degree the amount of FX that is produced. Some affected individuals have few or no symptoms while others may experience life- threatening bleeding. Typically this bleeding disorder manifests itself as a tendency to easy bruising, nose bleeding, heavy and prolonged menstruation and bleeding during pregnancy and childbirth, and excessive bleeding after dental or surgical interventions. Newborns may bleed in the head, from the umbilicus, or excessively after circumcision.

Benthic gastropods were heavily preyed upon throughout the MMR, the weaker shelled types being pushed out of the benthic zone into more isolated habitats. The Palaeozoic archaeogastropods were subsequently replaced by neritaceans, mesogastropods and neogastropods. The former typically have symmetrical, umbilicate shells that are mechanically weaker than the latter. These lack an umbilicus and also developed the ability to modify the interior of their shells, allowing them to develop sculptures on their exterior to act as defence against predators.

Four fine threads, of which the first one is partially beaded, lie in the flat between the first and second ridge; two between the second and third; one between the third and fourth. Below the fifth ridge is a flat furrow narrower than the rest. Below the furrow is a sixth ridge, slighter than the others. The base of the shell is closely covered with 11 spiral threads, which tend to become stronger and wider apart near the umbilicus.

The outer lip is sharp but not thin and brilliantly iridescent within. The inner lip is very much thickened by a pearly pad, which is very thick below where it envelops what might have been otherwise a tooth on the point of the columella. The pad is thinner in the middle of the columella, and thickens again at the junction with the body whorl, where it thins out quickly. The lip here is very slightly reflected on the umbilicus.

Upon the base of the body whorl the ridges become broader and broader. In the vicinity of the umbilicus they exceed double the breadth of the intervening furrows. The layer which this sculpture principally composes, is for the rest only about the thickness of a coat of varnish. And beneath it, it is showing very slight traces of longitudinal striae, appears silvery mother-of-pearl, which shines on the whorls of many specimens while still living.

The columella is short, straight, slightly tubercled on its inner side, hardly toothed in front, and still less angulated at its junction with the outer lip. The columellar lip is very thin, slightly excavated longitudinally, and reverted on the minute umbilicus, which it almost wholly conceals. Behind it is a very narrow furrow.H. Pilsbry (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia The thin operculum has a concave-convex shape with no visible external spirals.

Sculpture : The first and second whorls are smooth, the third comparatively coarsely cancellated, the fourth contains dense fine spiral cords crossed by fainter growth lines which tend to bead the interstices. The base is two-thirds of the total height. The wide and deep umbilicus is bordered by a conspicuous ridge, and has an elevated funicle winding within. The oblique aperture is rhomboidal, channelled by the umbilical ridge, and with a gutter at the termination of the funicle.

Ringicella is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Odontostomidae. Adult snails of this genus have an extremely unusual shell morphology, very similar to that found in the genus Anostoma Fischer von Waldheim, 1807, of which this genus was previously considered to be merely a subgenus. The adult snails in this genus carry their shells upside down, with the spire or apex at the bottom, and the umbilicus at the top.

Cymatonautilus is a genus of cymatoceratids from the middle and upper Jurassic of Europe, the Middle East and Asia characterized by a robust shell with a wide umbilicus and subquadrate whorl section, slightly wider than high. The flanks and venter are flattened. The flanks have a wide lateral groove; the venter a more narrow median groove. The suture has a shallow ventral lobe and broad concave lateral lobes, crossed obliquely by sinuous ribs that produce a deep ventral sinus.

T-box transcription factor Tbx4 is a transcription factor that belongs to T-box gene family that is involved in the regulation of embryonic developmental processes. The transcription factor is encoded by the TBX4 gene located on human chromosome 17. Tbx4 is known mostly for its role in the development of the hindlimb, but it also plays a critical role in the formation of the umbilicus. Tbx4 has been shown to be expressed in the allantois, hindlimb, lung and proctodeum.

Peripetoceras is a genus in the Clydonautilacean family, Liroceratidae. It can be recognized by its smooth, involute shell with a deep small umbilicus with rounded shoulders and steep convex wall; whorl section with flattened venter, rounded ventral shoulders and convergent slightly convex flanks; suture with slight ventral and lateral lobes; and small siphuncle located dorsally of the center. Peripetoceras ranges from the Lower Carboniferous (Upper Mississippian) to the Permian and has been found in Europe (England and Germany), Russia and China.

In the case of shells that have an umbilicus, the columella is a hollow structure. The columella of some groups of gastropod shells can have a number of plications or folds (the columellar fold, plaits or plicae), which are usually visible when looking to the inner lip into the aperture of the shell. These folds can be wide or narrow, prominent or subtle. These features of the columella are often useful in identifying the family, genus, or species of the gastropod.

Liroceratidae is an extinct family of nautilids, shelled marine molluscs, belonging to the Clydonautiloidea, consisting of generally smooth, involute, nautiliconic forms with a small umbilicus. The whorl section is usually depressed and broadly rounded, the suture only slightly sinuous, and the siphuncle usually more or less central. The Liroceratidae range from the Mississippian well into the Triassic and may even extend down into the upper Devonian. The Liroceratidae are probably derived from the Rutoceratidae and form the root stock of the Clydonautiloidea.

The right-coiled, globular shell of C. vindobonensis is about 17–21 mm high and 20–25 mm broad with 5,5-6 whorls. The umbilicus is completely covered in adult specimens. The lip is always red-brown at the inner and outer side with a fine white stripe at its margin. This specific lip coloration allows to separate it from the conchological similar Cepaea hortensis (pure white lip) and Cepaea nemoralis (consistent dark brown lip), with which C. vindobonensis often co-occurs.

Once by the ancestor of Aeonium and Monanthes, most likely from the Western Mediterranean region, with the closest extant relatives of these two genera (Sedum caeruleum, S. pubescens), coming from this region (Aeonium clade). The second migration was by an ancestor of a clade of three Sedum species (S. nudum, S. lancerotense and S. fusiforme (Acre clade)), which appear yo have originated in Mexico. The third occurrence likely involved the ancestor of a lineage within the genus Umbilicus (Rhodiola clade).

Biloclymenia is a genus in the ammonoid order Clymeniida which is characterized by a dorsal retrosiphonitic siphuncle with long adapically pointing septal necks. The shell of shell Biloclymenia is thickly discoidal, more or less involute, with a moderately wide umbilicus, lightly thickened sides and rounded venter. The shell is surface smooth, covered merely by growth lines which form two salients. The ventral lobe of the suture is wide and divided in two with a secondary lobe at the top of median saddle.

Hoffmanniinae is an adrianitid ammonoid cephalopod subfamily established for the Middle Permian genus Hoffmannia. Hoffmannia, named by Gemmellaro in 1887, is a discoidal adrianitid with a large umbilicus, prominent growth lines, and sutures with about 20 lobes. Note that the genus Hoffmannia is included in the Adrianitinae in the older Treatise on Invertebrate Paleontology volume on Ammonoidea and that it has been reassigned to the Hoffmanniinae, named by Spath in 1934, revived in the new Treatise volume on Carboniferous and Permian Ammonoidea.

There are few differences between sexes; the body structures are almost the same. A male's testes are not externally located, and the main difference between males and females is the location of the genital aperture in relation to the umbilicus and the anus. The lungs in a dugong are very long, extending almost as far as the kidneys, which are also highly elongated in order to cope with the saltwater environment. If the dugong is wounded, its blood will clot rapidly.

The shell of this species is an unusual shape for a helicid, elongatedly conical, 10 to 20 mm high, with a width of only 4 to 7 mm. The spire tapers regularly, but ends in a blunt tip. The oval aperture has a thin lip, and the narrow umbilicus is almost covered. The shell is very variable in color and markings, often having a cream or off-white background with many pale brown blotches, which are sometimes organized into spiral bands.

Ten cymatoceratid genera are described in the Treatise Part K, 1964. First to appear was the large, tightly involute, rapidly expanding Procymatoceras from the Middle Jurassic, followed by the Middle and Upper Jurassic Cymatonautilus which has a wide umbilicus and subquadrate whorl section. Procymatoceras and Cymatonautilus are followed by Cymatoceras and the similar Paracymatoceras. Six genera are restricted to the Cretaceous; Eucymatoceras and Heminautilus from the Lower Cretaceous; Anglonautilus from both the Lower and Upper Cretaceous; Deltocymatoceras, Epicymatoceras, and Syrionautilus.

The defect in the muscles is defined and the edges of the muscles are brought together with sutures to close the defect. In general, the child needs to stay in the hospital for 1 day and the healing is complete within 8 days. At times, there may be a fleshy red swelling seen in the hollow of the umbilicus that persists after the cord has fallen off. It may bleed on touch, or may stain the clothes that come in contact with it.

Appendicitis as seen on CT imaging Diagnosis is based on a medical history (symptoms) and physical examination, which can be supported by an elevation of neutrophilic white blood cells and imaging studies if needed. Histories fall into two categories, typical and atypical. Typical appendicitis includes several hours of generalized abdominal pain that begins in the region of the umbilicus with associated anorexia, nausea, or vomiting. The pain then "localizes" into the right lower quadrant where the tenderness increases in intensity.

The aperture (shell mouth) is typically almost as long as the entire shell with some specimens being described as 'almost abalone-shaped'. The species of Bayardella, when adult, often display medium-sized shells that are usually 5-9mm in size. The shells often display heavy spiral ridges on the periostricum, have a deep umbilicus and have a margin to the columellar that is reflected and curved slightly but without a fold. The shells of Bayardella, like other Planorbids, are typically sinistral.

The Conjecture claims that any convex, closed and sufficiently smooth surface in three dimensional Euclidean space needs to admit at least two umbilic points. In the sense of the Conjecture, the spheroid with only two umbilic points and the sphere, all points of which are umbilic, are examples of surfaces with minimal and maximal numbers of the umbilicus. For the conjecture to be well posed, or the umbilic points to be well-defined, the surface needs to be at least twice differentiable.

The radiating lines, almost microscopic in Gaza daedala, are in this form impressed in the early whorls near the suture, so as to produce a succession of short ripples, following the recurved lines of growth, which give a fringe-like ornamentation to the suture, at the rate of about five ripples to a millimeter. The margin of the suture in this form is distinctly appressed, forming a narrow border. The operculum has about seven whorls. The umbilicus is completely floored over.

The aperture is oblique above, arching more nearly to a perpendicular below. smoothly, evely reflected and thickened from the columella to the suture, with an internal channel behind the thickening. The columella is callous above, thinly and unevenly reflected half-way across the umbilicus, gently and very obliquely descending and smoothly passing into the basal part of the lip. The interior of the aperture, the lip, the umbilical callus, and a slight wash near the sutural junction, are brilliantly nacreous.

Besides this sculpture, the whole shell has a smooth, shining appearance, with very fine lines of growth. The body whorl has only a few spiral striae near the periphery. The whorls are slightly convex, the last one is a little depressed and much enlarged, but has no keel. The basal surface is smooth, with fine lines of growth and short, radiating striae round the umbilicus, which is large, pervious, funnel-shaped, sculptured with lines of growth and about 9 spiral lirae.

Shortly after completing and printing the project, while still living in Japan, Ithaka Darin Pappas and the photographs were presented in issue #11 of the prominent quarterly Japanese photographic art volume Déjà-Vu (published by Photo- Planète) along with features about renowned photographers Sasatani Takahiro, Shimose Nobuo, Inose Kou, Frederick Sommer and Nobuyoshi Araki.A photograph from UMBILICUS as featured on the cover of Speak Magazine in 1996. The image was considered disturbing, making it the worst-selling issue the magazine had published.

The outer lip shows a finely plicate thickening or rib within, and a strong tubercle near the upper angle. The basal margin is expanded, crenulated, and bearing a small but distinct central, very oblique fold within. The columella is very oblique, with a strong biplicate tooth below, a wide triangular projection at the middle, the whole edge reflexed but not distinctly crenulate. The insertion is located upon the side of the rather wide umbilicus, which has a radiately crenulated marginal rib.

Sculpture: the third, fourth and fifth whorls carry distinct spiral grooves latticed by oblique threads, which do not cross the intervening ridges. On the latter whorls this sculpture gradually fades away, leaving the body whorl smooth and polished. Around the axis on the base run four profound spiral grooves, the outer deepest, separated by smooth, prominent, narrow cords. The narrow umbilicus is bounded by a tuberculate rib, within which it is excavate, and spirally ascends the full height of the shell's interior.

Two lights lit the airlock interior, and three 16mm cameras — two in the airlock, one outside on a boom-mounted to the upper ring — recorded the historic first spacewalk. Belyayev controlled the airlock from inside Voskhod 2, but a set of backup controls for Leonov was suspended on bungee cords inside the airlock. Leonov entered the Volga, then Belyayev sealed Voskhod 2 behind him and depressurized the airlock. Leonov opened Volga's outer hatch and pushed out to the end of his umbilicus.

The interior of this cavity is of a fawn color. The outer lip is thin, everted, a little undulated, and adorned with a white band the whole length of its interior, with the exception of the edge, which is of a deep brown. The inner lip is spread out over the body of the shell. It is very thin, transparent, and terminated below by a projecting plate which covers the umbilicus, and seems also to form a part of it.

Abdominal wall defects are common in newborns with BWS and may require surgical treatment. These defects can range in severity from omphalocele (most serious) to umbilical hernia and diastasis recti (least serious). An omphalocele is a congenital malformation in which a newborn's intestines, and sometimes other abdominal organs, protrude out of the abdomen through the umbilicus. Newborns with an omphalocele typically require surgery to place the abdominal contents back into the abdomen in order to prevent serious infection or shock.

Because of this and because the waist is often synonymous with the stomach, one can become confused as to the exact location of the waist. Another confusing factor is that the waistline differs on different people. A study showed that self-reported measurements as opposed to measurement done by a technician, underestimated waist circumference and this underestimation increased with increased body size. In the study, waist circumference measured at the level of the umbilicus was larger than that measured at the natural waist.

A baby with isolated omphalocele, one of the defects included in the pentalogy of Cantrell. There are five characteristic findings in pentalogy of Cantrell: # an abdominal wall defect, #lower sternal defect, #congenital heart malformations, #absence of the diaphragmatic pericardium, #and an anterior diaphragmatic defect. Abdominal wall defects in pentalogy of Cantrell occur above the umbilicus (supraumbilical) and in the midline, and have a wide range of presentations. Diastasis recti, hernias, and omphalocele have all been described in conjunction with the pentalogy.

Fear of eating is commonly seen among those with the chronic form of SMA syndrome. For many, symptoms are partially relieved when in the left lateral decubitus or knee-to- chest position, or in the prone (face down) position. A Hayes maneuver, which corresponds to applying pressure below the umbilicus in cephalad and dorsal direction, elevates the root of the SMA, also slightly easing the constriction. Symptoms can be aggravated when leaning to the right or taking a face up position.

The inner lip is thick and folded back on the columella, which is short and incurved. At the bottom of the columella is a small but sharp tooth-like projection, below which is a short and abrupt notch. The groove or slit on the upper part of the body whorl, and the opening from the aperture (which characterizes the genus), is wide and deep, terminating in a curved indentation. The base of the shell is somewhat concave, but imperforate or without any umbilicus.

The morphology of Hirtudiscus boyacensis is described by Hausdorf; a disc-like shell with convex whorls, a protoconch with more or less distinct spiral striae and dense growth striae and hairs. The shell diameter is 3.5-5.2 mm.Hausdorf, 2003, p.179 The specimens from the surroundings of Barbosa and Moniquira differ from those from near Villa de Leyva in the smaller shell with more strongly arched whorls, a weaker spiral sculpture on the protoconch and an umbilicus that is on average narrower.

Suture is linear. The shell has five whorls, that are slightly flattened above, convex below, obtusely carinated at the periphery and obtusely angulated round the umbilicus, increasing regularly, the last nearly twice as wide as the penultimate, shortly deflexed in front, and slightly constricted behind the peristome. The aperture is semi-rotundate, oblique, margins approaching, united by a thin callus on the parietal wall. The peristome is scarcely thickened, reflexed, whitish, upper margin slightly curved, basal rounded, columellar ascending, and slightly dilated.

Chloritis bifoveata (Benson, 1856) from West Malaysia is smaller (width is 15 mm), and the spire is much deeper; Chloritis unguiculastra (Martens, 1867) is somewhat larger (width is 22 mm), is smooth without hair or hair pits, and is more regularly coiled; Chloritis ungulina (Linnaeus, 1758) is much larger (width is 44 mm) is smooth without hair or hair pits, has a groove at the base of the penultimate whorl near the umbilicus and the whorls are more flattened, not rounded.

Shell of Bellamya chinensis Species of the genus Cipangopaludina can be identified by their relatively large globose shells and concentrically marked opercula. The shell is conical and thin but solid, with a sharp apex and relatively higher spire and distant body whorl. This species has a small and round umbilicus and the spire is produced at an angle of 65–80°. Cipangopaludina chinensis exhibits light coloration as a juvenile and olive green, greenish brown, brown or reddish brown pigmentation as an adult.

If the patient chooses an interval tubal ligation, the procedure will typically be performed under general anesthesia in a hospital setting. Most tubal ligations are accomplished laparoscopically, with an incision at the umbilicus and zero, one, or two smaller incisions in the lower sides of the abdomen. It is also possible to perform the surgery without a laparoscope, using larger abdominal incisions. It is also possible to perform an interval tubal ligation hysteroscopically, which may be performed under local anesthesia, moderate sedation, or full general anesthesia.

The apex is very small and sharp, flattened on the one side, and with the minute 1¼ embryonic whorl projecting tumidly on the other. The 7½ whorls show a gradual increase. The upper ones are rounded. The later whorls are flat below the suture, then angulated, then flat on the conical slope of the spire, and then very slightly constricted above the carina, very slightly rounded on the base, with a flat and slightly impressed, but sloping border round the outside, sharply angulated at the umbilicus.

The columellar lip is patulous and reverted, with a furrow behind it, twisted, with a broad deep sinus above. A strong twisted tooth projects at about two- thirds of its length, below which is a smaller sinus running out into a point at the extreme end of the columella. This point corresponds to the umbilical carina. The umbilicus is more open than large, perpendicular and deep, being only slightly narrowed by the reverted coluimellar lip and by the corresponding ridge which twines spirally round the columellar wall.

Short's official Los Angeles County death certificate, 1947 The body had been cut completely in half by a technique taught in the 1930s called a hemicorporectomy. The lower half of her body had been removed by transecting the lumbar spine between the second and third lumbar vertebrae, thus severing the intestine at the duodenum. Newbarr's report noted "very little" ecchymosis (bruising) along the incision line, suggesting it had been performed after death. Another "gaping laceration" measuring in length ran longitudinally from the umbilicus to the suprapubic region.

On the lower whorls the sculpture consists of radiating ribs, with a row of compressed tubercles, at some distance from the channelled suture, which disappear on the upper whorls. These ribs are crossed by 2 spiral cords, with short, hollow scales, about 25 in number on the body whorl. On the last, rounded whorl, the base is bordered by a third row of smaller scales. The base is slightly convex, with 3 rather large, spiral cords, of which that bordering the umbilicus is the broadest.

The aperture is subcircular, straighter on the side of the slightly concave columella, which forms a conspicuous angle with the basal margin. The parietal wall has a thin layer of enamel, forming a small projection, covering part of the umbilicus. The interior of the nacreous aperture is smooth, and has a flattened rib near the outer and basal margin. It differs from the allied species, by the rows of short scales, and from all the preceding species, by the rounded periphery of the body whorl.

Hoplitoidea, formerly Hoplitaceae, is a superfamily of mostly Upper Cretaceous ammonites comprising families united by a similar suture pattern with multiple similar elements that tend to decrease in size going toward the umbilicus, at the inner edge of any whorl, and which are typically in a straight line. Sutural elements are commonly ammonitic, but in some saddles and in others both saddles and lobes are smooth and undivided. Shells are variable in form, both ribbed, evolute forms and smooth, involute forms are included.Arkell et al 1957.

The sharp lip is continuous all around, raised up and with the edge slightly everted in the umbilical region, so as to partially conceal the umbilicus, which is rather large and deep, nearly circular within. The thin operculum is horny, pale yellow, round-ovate, spiral, with two to three rapidly enlarging whorls, the nucleus excentric. The head of the animal is large, short, thick, rounded or truncate. It has two short, flat, obtuse, anterior tentacles, wide apart, but connected together by a transverse fold.

Apical and apertural view of a shell, with an arrow marking the half-colvered umbilicus Theba pisana The shell background color is a creamy white. Different individuals may have shells with varying degrees of pale to dark brown markings. The markings, when present, may be in the form of uninterrupted spiral bands, spiral dotted lines, or small radial smudges. The shell can be found in various colour variants, but is basically yellow or white with dark color bands or spots and often a dark bluish grey apex.

Homaloceras is the most primitive, with a laterally compressed, cyrtoconic to gyroconic shell with a narrow, concave venter, broadly convex flanks, and rounded dorsum, The suture is only slightly sinuous, the siphuncle tubular and near the venter. Centroceras, the type genus, is evolute with only a few, rapidly expanding whorls and wide, perforate umbilicus. The cross section may be faintly hexagonal from the effect of a median ridge on either flank, otherwise is tetragonal. Flanks converge from a broad dorsum to a narrow, barely convex venter.

Strongly convex to convex above, flattened below, with 5.2–5.8 whorls. Whorls rounded, sometimes with slight peripheral keel (the keel prominent in subadults); sutures shallow on most of spire, often deeper above last half of body whorl. Umbilicus rather narrow, symmetrical, deep, partly overlapped by reflected peristome, exposing upper whorls in oblique view. Mouth broadly oval, except where interrupted by penultimate whorl; last half of body whorl expanding and often descending markedly below penultimate whorl, sometimes also with downturn just behind edge of mouth.

The transpyloric plane, also known as Addison's plane, is an imaginary horizontal plane, located halfway between the suprasternal notch of the manubrium and the upper border of the symphysis pubis at the level of the first lumbar vertebrae, L1. It lies roughly a hand's breadth beneath the xiphisternum or midway between the xiphisternum and the umbilicus. The plane in most cases cuts through the pylorus of the stomach, the tips of the ninth costal cartilages and the lower border of the first lumbar vertebra.

After the application of local anesthesia, a vertical skin incision is made one third of the distance from the umbilicus to the pubic symphysis. The linea alba is divided and the peritoneum entered after it has been picked up to prevent bowel perforation. A catheter is inserted towards the pelvis and aspiration of material attempted using a syringe. If no blood is aspirated, 1 litre of warm 0.9% saline is infused and after a few (usually 5) minutes this is drained and sent for analysis.

The intercalary threads appear on the penultimate whorl. On the first half of the body whorl they become numerous, covering the whole surface uniformly, but a little coarser on the verge of the umbilicus which is moderately wide and deep. This sculpture becomes obsolete and the last quarter of the body whorl is perfectly smooth and polished. The axial sculpture consists of numerous retractively arcuate threads beginning at the suture and extending feebly to the periphery on the upper part of the spire, later becoming obsolete.

The nucleus and interior walls of the umbilicus is dark brown. Several of the spiral grooves above and below are marked by a darker brown than the rest, and appear as brown lines. (Original description by W.H. Dall) The sculpture above, on the nuclear whorls, consists of close-set sharp longitudinal grooves with the ridges between them rounded and more or less beaded or nodulous. They are crossed by more or less evident lines of growth, which, however, are not necessarily coincident with the beading where present.

The SPL technique has been used to perform many types of surgery, including adjustable gastric banding, appendectomy, cholecystectomy, colectomy, hernia repair, hysterectomy, sleeve gastrectomy, nephrectomy, and sacrocolpopexy. SPL has been employed by surgeons at Cleveland Clinic for clinical trials and in the Geneva University Hospital in Switzerland. Although a number of single- incision techniques use specialized instrumentation, most SPL operations in the United States and Europe have used standard instrumentation. The TriPort+ can be inserted with its introducer through a 15 mm incision at the umbilicus.

The shell varies in altitude, in the presence or absence of the yellow subsutural line and especially in the characters of the umbilicus, which is either closed, or more or less open. This is not dependent on age. Radula of Bathymophila calliomphala; rhachidian tooth and laterals The radula is short, with a rather restricted number of uncini, and the shape of the teeth agrees with that of the known species. The rhachidian tooth has a subquadrate body, narrower in front, with concave upper and convex basal margin.

At the suture there is a double smaller rib, and there is a finer one posterior to the periphery. The transverse riblets of the penultimate whorl show increasing revolution of the whorls and become more slender and closer together. And thus the fenestrated ornament is somewhat obscured on the front part of the body whorl. Below the periphery there are about five revolving equal-sized ribs, more or less gemmulated at the intersections of transverse sigmoidal threads, the one margining the umbilicus most conspicuously so.

They are ventricose, with delicate, highly elevated spiral rib-striae,- of which there are about 5 on the upper and 10 on the last whorl. The surface of the ribs is slightly tuberculous, and the last one overhangs the succeeding whorl so as to form a broad deep channel at the suture. The interspaces have about the same width as the ribs, and are beautifully barred with close-set laminae. The base of the shell isconvex, with a small deep scalariform umbilicus, sculptured like the spire.

The umbilical cord enters the fetus via the abdomen, at the point which (after separation) will become the umbilicus (or navel). Within the fetus, the umbilical vein continues towards the transverse fissure of the liver, where it splits into two. One of these branches joins with the hepatic portal vein (connecting to its left branch), which carries blood into the liver. The second branch (known as the ductus venosus) bypasses the liver and flows into the inferior vena cava, which carries blood towards the heart.

The margin is separated from the central part by a deep groove, with about 7 spirals and faint growth striae. The umbilicus is large, pervious, scalar, and bordered by a strong rib which is surrounded by a deep groove, The umbilical wall is perpendicular. The aperture is rhombic, with convex upper, outer and basal margins. The keel is protracted in a claw in the younger specimen The columellar margin is excavated, slightly thickened, angular below near the umbilical keel, and forming there a somewhat tongue- shaped triangle.

As the foetus grows larger, the mid-gut loop is drawn back through the umbilicus and undergoes a further 180° rotation, completing a total of 270° rotation. At this point, about 10 weeks, the caecum lies close to the liver. From here it moves in a cranial to caudal direction to eventually lie in the lower right portion of the abdominal cavity. This process brings the ascending colon to lie vertically in the lateral right portion of the abdominal cavity apposed to the posterior abdominal wall.

Drawing of juvenile shell of Anostoma depressum. A colored drawing of an adult shell of Anostoma depressum This is one of the most peculiar genera of land snails. The prominent feature of an upturned aperture (causing the adult snail to carry the shell spire down) is reflected in its scientific name Anostoma: ano, means up, or backwards, and stoma means mouth, from the Greek. In this genus, the adult snails carry the shell completely upside down, with the umbilicus uppermost, and the spire facing downwards.

Masonoceras is a genus of Karagondoceratids from Lower Mississippian strata, the shell of which is thinly subdiscoidal to discoidal with an acute ventral margin in late ontogeny. Whorls are strongly embracing, umbilicus narrow to occluded. The mature external suture contains a wide trifid ventral lobe, the flanking prongs longer that the medial, an asymmetrically rounded lateral saddle and a deeper asymmetric pointed lateral lobe. Internal molds of the type, Mesoceras Kentuckiense show presence of a broad hyponomic sinus flanked by high rounded vantrolateral salients.

The umbilical region, is one of the nine regions of the abdomen. It is the region that surrounds the area around the umbilicus and is placed approximately half way between the xiphoid process and the pubic symphysis. This region of the abdomen contains part of the stomach, the head of the pancreas, the duodenum, a section of the transverse colon and the lower aspects of the left and right kidney. The upper three regions, from left to right, are the left hypochondriac, epigastric, and right hypochondriac regions.

Craspedites, described by Aleksei Petrovich Pavlow in 1892, is characterized by a small, up to about 5 cm in diameter, smooth, essentially involute shell with simple ammonitic sutures. Whorl section is rounded, venter smooth; umbilicus small, exposing the dorsal portion of the inner whorls. Main sutural elements, primary saddles and lobes, are modified by small secondaries. Craspedites was thought to be restricted to the Upper Jurassic Tithonian until discovery of a new species, C. sachsi, described from the Berriasian age of Russia by A. E. Igolnikov in 2012, named in honour of paleontologist V.N. Sachs.

Enoploceras is a Tainoceratid genus, a nautiloid cephalopod in the order Nautilida, known from Triassic sediments in Europe, India, Timor, and the state of Idaho. Enoploceras is characterised by its moderately involute shell with a broad subquadrarte whorl section; venter and flanks flattened; ventral and umbilical shoulders sharply rounded; flanks with nodes at ventral or umbilical shoulders or both, and with radial ribs and sinuous growth lines; umbilicus deep, straight walled, and with small perforation. The siphuncle is subcentral. Sutures form shallow lobes on the venter, flanks and dorsum.

Condraoceras is a genus of liroceratids from the Pennsylvanian of North America and Lower Permian of Europe with a compressed, involute, nautiliconic shell; subcircular whorl section; small umbilicus with a rounded shoulder; suture with shallow ventral and lateral lobes; and narrow subcentral siphuncle. Liroceras, from the same time and type of the family, differs in having a reniform whorl section and essentially straight sutures at maturity. Peripetoceras, another related genus, has a flattened venter, slight ventral and lateral lobes in the suture, and a siphuncle offset dorsally from the center.

Anchor Church is included on the list of Derbyshire Regionally Important Geological Sites (RIGS), and is also listed as a Local Wildlife Site. Species of note found here include wall pennywort (Umbilicus rupestris) which grows on the rocks themselves, plus shining pondweed (Potamogeton lucens), a very rare "Red Data List" plant in Derbyshire, found in the backwater channel below the rocks and two other sites elsewhere in the county. Other species of note recorded near Anchor Church include Eurasian otter, and 1970s records of small water-pepper (Persicaria minor).

There are over the whole surface very faint traces of spirals. At the bottom of each whorl, about 0.25 mm. above the suture, is a sharp narrow thread, which on the body whorl is bordered below by a second, rather higher and sharper, which forms the carina, and which on the spire is buried by the overlap of the succeeding whorl. On the base of the shell there are about eleven fine spirals, within which is a strong furrow, and a projecting, crenulated, or ropelike thread forming the edge of the umbilicus.

The columellar margin is rather thick, concave in its upper part, and terminating in a sort of tooth below. The parietal wall is covered by a thick layer of enamel, thickened at its margin and connected to the columella by a broad, rounded tongue-shaped projection, covering part of the umbilicus, whose largest diameter, from the base of the columella to the opposite side, is about 2/5 of the diameter of the shell. The thin operculumis horny, many-whorled, and concave at the outer side. The radula has the teeth in about 48 rows.

Besides these, the whole surface is covered with sharp, not approximate, microscopic spirals. Longitudinals: tTere are numerous distinct lines of growth, which on the second whorl are like minute radiating spokes, and in the superior sinus (i. e. between the suture and the first spiral) are sharp and distinct, and more remote than elsewhere on the surface, except on the base round the umbilicus, where, though less sharp, they are even more distinct. Colour: a dead chalky white, with an exquisite pearly nacre below the outside layer and within the shell.

The parietal wall is covered by a much expanded, smooth layer, loosened from the body whorl near the place of the wanting umbilicus. The columella is very strong and tortuous, thickened above, then slightly attenuated, with a strong square tooth, from which a tortuous rib runs to the left, enclosing a triangular pit and forming a deep sinus between the columella and basal margin. The interior of the aperture is very iridescent, but covered in part in the adult shells, by the porcellaneous internal rib.Schepman 1908–1913, The Prosobranchia of the Siboga Expedition; Leyden,E.

Another similar row, a little lower on the concentric ribs and a third, consists of compressed tubercles, (about 30 on the last whorl) near the base of the whorls. These tubercles, especially those of the peripheral row, are connected by spiral lirae, of which the lowest represents the keel. The convex base is sculptured by four spiral cords, of which that near the keel, bears strong, compressed tubercles. Those of the more central cord are smaller, and the innermost two are strongly beaded, the inner one borders the umbilicus.

It may be helpful to point out, to start with, that many problems in understanding concepts integral to East Asian culture have arisen simply due to divergent use of transcription, uncertain pronunciation and out-of-context translation, starting within the wider Asian community (Chinese into Japanese e.g.), and from there spreading by different pathways to the West. In martial arts, the Hara or Dantian is sometimes considered as equivalent to the lower of the three dantian (tanden in Japanese1). Various styles of martial arts describe this as being just below or directly behind the umbilicus.

The increase in suture complexity over the 108 m.y. duration resulted from the iterative of addition of umbilical lobes, serration of lobes, and the subdivision of lateral and ventral lobes. As many as 12–15 replicate, U-shaped umbilical lobes, originating at the umbilicus and migrating across the flanks were added to the sutures during both ontogeny and phylogeny. Not only did the Prolecanitida evolve their sutures differently than in the Goniatitda, by increasing the number of umbilical lobes rather than by subdivision of the lateral saddle, their body chambers were short by comparison.

A hernia is present at the site of the umbilicus (commonly called a navel or belly button) in newborns; although sometimes quite large, these hernias tend to resolve without any treatment by around the age of 2–3 years. Obstruction and strangulation of the hernia is rare because the underlying defect in the abdominal wall is larger than in an inguinal hernia of the newborn. The size of the base of the herniated tissue is inversely correlated with risk of strangulation (i.e., a narrow base is more likely to strangulate).

The vesico-urethral portion is the deepest, continuous with the allantois. It absorbs the ends of the Wolffian ducts and the associated ends of the renal diverticula, and these give rise to the trigone of urinary bladder and part of the prostatic urethra. The remainder of the vesico-urethral portion forms the body of the bladder and part of the prostatic urethra; its apex is prolonged to the umbilicus as a narrow canal, the urachus, which later is obliterated and becomes the median umbilical ligament of the adult.

Rosalina is a genus of foraminifera included in the rotaliid family Rosalinidae. Rosalina has a smooth plano-convex to concavo-convex trochospiral test in which the chambers are rapidly enlarging and all visible on the convex spiral side and subtriangular and strongly overlapping on the umbilical side, the final chamber taking up about one-third of the circumference. Sutures on the spiral side are depressed and oblique, curving back at the periphery. The umbilicus is open, partly covered by triangular umbilical flaps extending from each chamber of the final whorl.

Shell is solid, of a light ochre color, biconcave, regularly striated with very fine axial riblets, with numerous periostracal hairs (visible in this well cleaned sample as hair pits), covering the whole surface. The spire is deeply sunken, with 3¾-4½ whorls. Whorls are rounded, first whorls very narrow, the last one very large, and embracing the preceding one, distinctly descending in front. The umbilicus is deep, and very small (about 1/20 of the width of the shell) and partly hidden by the expanded columellar side of the peristome.

The statue was removed from the pillar in 1915 The Seffin Stone is said to mark the centre of Ireland. Mentioned by Geraldus Cambrensis, who referred to it as Umbilicus Hiberniae, the indentations on the stone are as old as megalithic sites, such as Newgrange. Myths claim that the indentations are from the hand of Finn MacCool, hence the origin of the name as Suigh Finn (pronounced "See-Finn"), the Seat of Finn. It is located to the left of the gates to St John's Hall, on John's Mall, close to Emmet Square.

Allonautilus scrobiculatus, also known as the crusty nautilus or fuzzy nautilus, is a species of nautilus native to the waters around New Guinea, specifically New Britain and Milne Bay, and the Solomon Islands. A. scrobiculatus is instantly recognizable by the large open umbilicus, which is around 20% of the shell diameter at its widest point. This species, along with the closely related A. perforatus, were originally placed in the genus Nautilus, but have recently been given their own genus on account of significant morphological differences.Ward, P.D. & W.B. Saunders 1997.

The whorls are generally a little carinated on the upper surface, especially the earlier whorls, by one or two prominent spiral riblets. Below they are full and rounded, with a small but well-marked umbilicus. The radiating sculpture of the lines of growth is occasionally irregular so as to form faint waves, but usually inconspicuous. The spiral sculpture consists of fine close little-raised threads, with on the upper surface one and on the periphery another stronger thread or carination, seldom nodulous, and stronger on the earlier whorls.

The intercalary threads appear on the penultimate whorl and on the first half of the body whorl they become numerous, covering the whole surface uniformly, but a little coarser on the verge of the umbilicus which is moderately wide and deep. This sculpture becomes obsolete and the last quarter of the body whorl is perfectly smooth and polished. The axial sculpture consists of numerous retractively arcuate threads beginning at the suture and extending feebly to the periphery on the upper part of the spire, later becoming obsolete. The base of the shell is rounded.

Three strong spirals girdle the whorls. The one at the shoulder is strongly beaded; one at the middle of the whorl is minutely undulate, and the third at the suture is simple, and obscured on all the whorls but the last by the suture being laid against it. On the body whorl there may be a few microscopic spiral threadlets between the shoulder and the median spiral. Between the anterior spiral and the edge of the umbilicus on the base there are six or eight fine-channeled spiral grooves.

The umbilicus is small, deep, and does not show any whorls. The aperture is somewhat oblique, circular with a slight sutural angle, and not modified by the body whorl to which the simple, continuous peritreme is but slightly attached. The aperture often has an indistinct thread just within the inner lip, fading out above and below, so that it extends but about halfway round the aperture. It is much nearer the edge along the columellar margin than at the ends and is evidently to prevent the thin operculum being drawn in too far.

The thorax and abdomen are separate and each twin has its own umbilicus and umbilical cord. The union may involve the entire diameter of the head or only a small portion. This suggests that although many different kinds of vulnerabilities are already known in the scientific community, there are an infinite number of variations that can occur. Most of these variations are based on the rotation of one twin's skull to the other and the different phenotype sub-groups of craniopagus twins are based on all these rotational conformations.

Minaselates is a monospecific genus erected to harbor Minaselates paradoxa, and one of the seven genera currently included in the family Epiphragmophoridae. It is apparently closely related to the genus Epiphragmophora, but its shell can be distinguished by the protoconch sculpture, outline of the apex, complex teleoconch microsculpture and closed umbilicus fused with the shell wall. Regarding the soft parts, the presence of a long and thin kidney that extends more than half the length of the pulmonary cavity, as well as a flagellar caecum and a smooth jaw also distinguish Minaselates from Epiphragmophora.

Abdominal regions are used for example to localize pain. To promote clear communication, for instance about the location of a patient’s abdominal pain or a suspicious mass, the abdominal cavity can be divided into either nine regions or four quadrants. ;Quadrants The abdomen may be divided into four quadrants, more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersect at the patient’s umbilicus (navel). The right upper quadrant (RUQ) includes the lower right ribs, right side of the liver, and right side of the transverse colon.

Below these there is a minutely white-speckled belt, and then at the periphery a series of red spots. On the base of the shell, the umbilicus is fleshy-whitish; outside of this there is a red area closely mottled with opaque white; and between this tract and the periphery there is a pale zone, sometimes marked with distant radial series of two red dots each. The surface is smooth except at and above the periphery, where there are several spiral striae. The 5½ whorls are slightly convex, parted by an impressed suture.

The height of the shell attains 9 mm, its diameter varies between 11 mm and 13 mm. The thick, solid, imperforate shell has a little hollow or depression at the place of the umbilicus. It is orbicularly conoid or subdepressed with 5 whorls. The first whorl is whitish, often eroded, the last brownish, purplish or red, obliquely striated, and ornamented with spiral granulose lirae, 3 on the penultimate whorl, 8 or 9 on the body whorl, of which the first is composed of larger beads, and the fourth forms the periphery.

The outer lip is dilated, undulated, tinged with black, or a deep brown upon the edge. The inner lip is whitish, spread out in a very thin plate upon the belly of the body whorl. The columella is smooth, polished, and forms at the left of the umbilicus a thick rib, marked by transverse striae, which terminates at the emargination of the base. The external surface of this shell is of a uniform reddish fawn color ; nevertheless the ribs are varied with wide spots or irregular brown and white blotches which are very remarkable.

Pruritic urticarial papules and plaques of pregnancy (PUPPP), known in United Kingdom as polymorphic eruption of pregnancy (PEP), is a chronic hives-like rash that strikes some women during pregnancy. It presents no long-term risk for either the mother or unborn child despite frequently severe pruritus. PUPPP frequently begins on the abdomen and spreads to the legs, feet, arms, chest, and neck. Papules and plaques usually first appear on the abdomen (although not on the umbilicus/belly button) and often spread to the legs, chest, underarms, etc.

The columella is smooth, polished, and forms at the left of the umbilicus a thick rib, marked by transverse striae, which terminates at the emargination of the base. Kiener (1840). General species and iconography of recent shells : comprising the Massena Museum, the collection of Lamarck, the collection of the Museum of Natural History, and the recent discoveries of travellers; Boston :W.D. Ticknor,1837 (described as 'Dolium perdix) The ground color of the shell is a bluish white, covered with irregular spots of a red brown, bordering upon the violet.

Caput medusae is the appearance of distended and engorged superficial epigastric veins, which are seen radiating from the umbilicus across the abdomen. The name caput medusae (Latin for "head of Medusa") originates from the apparent similarity to Medusa's head, which had venomous snakes in place of hair. It is also a sign of portal hypertension. It is caused by dilation of the paraumbilical veins, which carry oxygenated blood from mother to fetus in utero and normally close within one week of birth, becoming re-canalised due to portal hypertension caused by liver failure.

The families are described as: The Clydonautilidae, named by Hyatt in 1900, were the first to be defined and provide the name for the superfamily. Clydonautilids are characterized by generally smooth, involute, globular to compressed shells with a very small to occluded (hidden) umbilicus and sutures with prominent lobes and saddles. Their range is from the mid to Upper Triassic. The Liroceratidae, named by Miller and Youngquist in 1949, are the ancestral family, which gave rise to the other four, and which has the longest duration, from the Upper Devonian to the Upper Triassic.

The vesico-urethral portion is the deepest portion, continuous with the allantois. It absorbs the ends of the mesonephric ducts and the associated ends of the renal diverticula, and these give rise to the trigone of urinary bladder and part of the prostatic urethra. The remainder of the vesico- urethral portion forms the body of the bladder and part of the prostatic urethra; its apex is prolonged to the umbilicus as a narrow canal, the urachus, which later is obliterated and becomes the median umbilical ligament of the adult.

The whorls are prominently keeled above the suture, the keel being finely crenulate. The base of the shell is a little convex, excavated towards the peripheral keel, with three fine spirals at some distance from the periphery and a few, scarcely visible ones towards the central part, moreover with numerous very fine curved growth striae. The umbilicus is moderately large, pervious, scalar, with a rib at its margin and a groove just around this rib. The aperture is subtriangular, its margins broken, the upper one convex, the basal one nearly straight.

One or two spiral elevated striae may be observed on part of the upper whorls. Moreover the whole shell is covered with fine growth striae, which form a large sinus above near the suture and are protracted below near the keel, following the direction of the riblets. The base of the shell is rather smooth, but sculptured by similar striae as on the upper part, being partly riblike. The whole base is covered with spiral striae, most conspicuous towards the umbilicus and keel, leaving a smoother median space.

The aperture is perpendicular, rhomboidal, the basal and palatal lines being parallel, the other two are somewhat diverging and curved, broader than high. The outer lip is sharp and thin, not patulous, not descending, with a shallow open sinus below the suture, then, about the middle of the whorl, it advances with a rounded sweep, retreating sharply across the carina to form the open rounded basal sinus toward the outer edge of the base. The columellar lip is sharp and thin. It rises from the body a good way within the edge of the umbilicus.

In the next interstice they are concave and at last convex towards the basal liration. The body whorl is rounded, with a strong peripheral keel, being the basal one of the upper whorls, and a convex base. There is another spiral at some distance from the peripheral keel, and 12 basal spirals of which three more spaced ones, at a larger distance from the subperipheral spiral, and 9 more central spirals, which are flatter, at subequal distances, the innermost bordering the umbilicus. These spirals are connected by small radiating riblets in the interstices.

In the growing fetus, a major source of blood to the liver is the umbilical vein, which supplies nutrients to the growing fetus. The umbilical vein enters the abdomen at the umbilicus and passes upward along the free margin of the falciform ligament of the liver to the inferior surface of the liver. There, it joins with the left branch of the portal vein. The ductus venosus carries blood from the left portal vein to the left hepatic vein and then to the inferior vena cava, allowing placental blood to bypass the liver.

The Roman Kingdom's earliest shrines and temples were located on the southeastern edge. These included the ancient former royal residence, the Regia (8th century BC), and the Temple of Vesta (7th century BC), as well as the surrounding complex of the Vestal Virgins, all of which were rebuilt after the rise of imperial Rome. Other archaic shrines to the northwest, such as the Umbilicus Urbis and the Vulcanal (Shrine of Vulcan), developed into the Republic's formal Comitium (assembly area). This is where the Senate—as well as Republican government itself—began.

Otherwise, the incision is made over McBurney's point (one-third of the way from the anterior superior iliac spine to the umbilicus), which represents the most common position of the base of the appendix. #The various layers of the abdominal wall are opened. In order to preserve the integrity of abdominal wall, the external oblique aponeurosis is split along the line of its fibers, as is the internal oblique muscle. As the two run at right angles to each other, this reduces the risk of later incisional hernia.

It typically has a single prominent median ridge on the rostrum, but can have faint lateral ridges, which are more pronounced in calves. Bryde's whale, on the other hand, has three prominent ridges on the rostrum. It has 45 to 95 ventral grooves that extend past the umbilicus. The type specimen (NSMT-M32505) had 203-208 pairs of baleen plates that were "short and broad with uncurled, stiff, grayish-white fringes", while NRIFSF6 had an estimated 181-190 on the right side – fewer than any other species in its genus.

There is usually, too, a third ridge or carina, generally coarsely nodose, between the two already described. The base of the shell is more or less convex, generally shows microscopic concentric striae under a lens, and has about 5 low, narrow, separated spiral lirulae. The columella and the inside of the umbilicus are either green or white.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia (described as Chlorostoma coronulatum) This species is thus characterized by the two angulations on the body whorl and the fine, spiral sculpture between the two keels.

The height of the shell attains 3.3 mm. The small, thin shell has a subconic shape with four rounded whorls and a minute glassy nucleus. The radiating sculpture consists of fine oblique incremental lines, which on the early whorls rise into very fine threads, visible crossing the interspaces of the spiral sculpture. The spiral sculpture consists of (on the body whorl) about seven strong smooth even cinguli on the top of the whorl, and fourteen or fifteen more rather smaller from the periphery to the brink of the umbilicus.

Olive- brown in color, they are surrounded by a uniform gelatinous sheath about 6 μm thick, and have an umbilicus (a single compact strand of fused hyphae) at the top. The primary septum is initially laid down in the lower third of the ascospore, and the larger, upper hemispores are subsequently divided by a transverse septum. The ascospores germinate readily from one or several cells. When grown in pure culture, the fungus forms conidiomata that make ellipsoidal, one-celled, brown conidia, measuring 4.5–7 by 2.5–3.5 μm.

A paraumbilical (or umbilical) hernia is a hole in the connective tissue of the abdominal wall in the midline with close approximation to the umbilicus. If the hole is large enough there can be protrusion of the abdominal contents, including omental fat and/or bowel. These defects are usually congenital and are not noticed until they slowly enlarge over an individual's life time and abdominal contents herniate through the hole creating either pain or a visible lump on the abdominal wall. If abdominal contents get incarcerated (or stuck) in the hole this can cause pain.
