Their mouth and gill openings are situated on the ventral surface of the head (top right). In the most primitive forms, such as the Silurian genus Hanyangaspis (top), the median dorsal inhalent opening is broad and situated anteriorly. In other galeaspids, it is more posterior in position and can be oval, rounded, heart-shaped or slit-shaped. In some Devonian galeaspids, such as the hunanaspidiforms Lungmenshanaspis (middle) and Sanchaspis (bottom right), the headshield is produced laterally and anteriorly into slender processes.
|
|
After reaching the medial wall of the orbit, the OA again turns anteriorly. The posterior ethmoidal artery enters the nose via the posterior ethmoidal canal and supplies the posterior ethmoidal sinuses and enters the skull to supply the meninges. The OA continues anteriorly, giving off the anterior ethmoidal artery which enters the nose after traversing the anterior ethmoidal canal and supplies the anterior and middle ethmoidal sinuses, as well as the frontal sinus and also enters the cranium to supply the meninges.
|
|
The tibia is then drawn forward anteriorly. An increased amount of anterior tibial translation compared with the opposite limb or lack of a firm end-point may indicate either a sprain of the anteromedial bundle or complete tear of the ACL. If the tibia pulls forward or backward more than normal, the test is considered positive. Excessive displacement of the tibia anteriorly suggests that the ACL is injured, whereas excessive posterior displacement of the tibia may indicate injury of the posterior cruciate ligament.

The proximomedial margin is nearly straight, whereas the proximolateral margin is concave anteriorly and convex posteriorly. The oval cross-section of the upper shaft gradually transforms into a rounded D-shape at mid-shaft, with the long axis of the cross section extending transversely. This ‘D’ shape becomes more anteriorly compressed towards the distal end, with a transversely rounded anterior face and increasingly flattened posterior face. This is associated with the strong transverse expansion of the distal shaft and distal end of the bone, as originally described as a twisting of the bone.
|
|
When the scapula is moved laterally it lies in a sagittal plane with the glenoid cavity facing anteriorly. At this position, the lateral end of the clavicle is rotated anteriorly so that the clavicle lies in a frontal plane. While this slightly closes the angle between the clavicle and the scapula, it also widens the shoulder. The scapula can be elevated and depressed from the neutral position to a total range of ; at its most elevated position the scapula is always tilted so that the glenoid cavity is facing superiorly.

There are also subconfluent triangular blackish marginal dots around the apex and termen, separated anteriorly by ochreous-whitish or yellowish dots.
|
|
The forewings are rather dark grey with a rather oblique transverse elliptical blackish blotch at one-third, yellowish edged, nearly reaching the dorsum, not nearly reaching the costa.

Pederpes, a tetrapod from the Early Carboniferous period, also has hindlimbs containing 5 digits that are rotated to face anteriorly. Unlike previous tetrapods, who have been only partially adapted to land, Pederpes has the novel ability to bend its limbs and propel itself forwards in a terrestrial setting. This is attributed to the symmetry of the digits and limbs in Pederpes, allowing it to rotate its hindlimbs to an anteriorly facing position and propel itself from the edge of the foot when moving forward. This morphological development of bendable wrists and ankles can distinguish Pederpes the first true terrestrial tetrapod.

Aqueous humor flows from the ciliary processes into the posterior chamber, bounded posteriorly by the lens and the zonules of Zinn, and anteriorly by the iris. It then flows through the pupil of the iris into the anterior chamber, bounded posteriorly by the iris and anteriorly by the cornea. From here, the trabecular meshwork drains aqueous humor via the scleral venous sinus (Schlemm's canal) into scleral plexuses and general blood circulation. In open/wide-angle glaucoma, flow is reduced through the trabecular meshwork, due to the degeneration and obstruction of the trabecular meshwork, whose original function is to absorb the aqueous humor.

Dolichopteridae, which lived in the Silurian and Devonian periods, had outer surfaces that were either smooth with pustules and semilunar scales. Their compound eyes were arcuate and located anteriorly on the prosoma (head). Their abdomens had epimers (lateral projections). The telson, (tail) was lanceolate.
|
|
Aeolosaurus had vertebral lateral fossae that resembled shallow depressions. Fossae that similarly resemble shallow depressions are known from Saltasaurus, Alamosaurus, Malawisaurus, and Gondwanatitan. Its middle tail vertebrae's neural spines angled anteriorly when the vertebrae are aligned. These vertebrae resemble those of Cedarosaurus, Venenosaurus, and Gondwanatitan.

The surface of the entire shell is covered by close-set rounded spiral ribs that override the peripheral nodes. The aperture is elongate, extended anteriorly as a narrow siphonal canal. The inner lip is callused, the edge of the callus discrete.H. S. Ladd. 1982.
|
|
Air flows anteriorly (caudal to cranial) through the parallel parabronchi. These parabronchi have honeycombed walls. The cells of the honeycomb are dead-end air vesicles, called atria, which project radially from the parabronchi. The atria are the site of gas exchange by simple diffusion.
|
|
The thin, subdiaphanous, imperforate shell has a conoidal shape. The whorls display transverse series of granules, the last rounded on the periphery. The thick columella is spirally twisted posteriorly, ending anteriorly in an obtuse, prominent point. The thin outer lip is simple and acute.

|
The small, smooth, bright shell has a turbinate shape. The outlines of the spire are convex, variously maculated with rose color and reddish brown. The four whorls are very convex, and rapidly increasing. The body whorl is produced anteriorly, separated by well impressed sutures.
|
|
Chenoprosopus belongs to clade Edopoidea, a superfamily of temnospondyl. Edopoidea has several primitive characteristics of temnospondyls. These are namely the retention of intertemporal ossification, and the palatine rami of the pterygoids meeting anteriorly to exclude the palatines and vomers from the interpterygoid vacuity margins.
|
|
The ulnar olecranon process has a mediolaterally pinched posterior margin. The ulnar distal end bends anteriorly and is strongly expanded laterally. The proximal end of metacarpal II has a strong ventrolateral extension. Metacarpal III is laterally bowed and adorned with a longitudinal ventral groove.

|
|
All of the incised, spiral lines on base and spire are crossed by very slender, axial threads, which lend these channels a somewhat pitted appearance. The sutures are well impressed. The aperture is moderately large, oval, and effuse anteriorly. The posterior angle is acute.
|
|
The aperture is oval, effuse anteriorly. The posterior angle is acute. The outer lip is thin, showing the external sculpture within, rendered wavy by the keels. The columella is stout, reflected, reinforced by the base, and provided with a weak fold at its insertion.

|
The forewings are light brownish, faintly purplish tinged, sprinkled with fuscous and with a dark purplish-fuscous triangular blotch with indigo- blue reflections occupying nearly the median third of the costa, reaching more than halfway across the wing, edged anteriorly with whitish-ochreous suffusion. There is a small blackish dot on the fold at one-third of the wing, one towards the dorsum beyond this, one below the middle at two-thirds, and one obliquely beyond and above this. Some minute ill-defined blackish dots are found around the posterior part of the costa and termen. The hindwings are grey, paler and thinly scaled anteriorly.
|
|
The middle layer, known as the vascular tunic or uvea, consists of the choroid, ciliary body, pigmented epithelium and iris. The innermost is the retina, which gets its oxygenation from the blood vessels of the choroid (posteriorly) as well as the retinal vessels (anteriorly). The spaces of the eye are filled with the aqueous humour anteriorly, between the cornea and lens, and the vitreous body, a jelly-like substance, behind the lens, filling the entire posterior cavity. The aqueous humour is a clear watery fluid that is contained in two areas: the anterior chamber between the cornea and the iris, and the posterior chamber between the iris and the lens.
|
|
The forewings are fuscous grey, the margins narrowly dark fuscous and with the costal edge, hindmarginal edge, and all veins marked by bright carmine lines. There is a very ill-defined straight oblique cloudy dark grey transverse line from the middle of the costa to the inner margin at two-thirds. There is also a very ill-defined roundish pale yellow spot on middle of the inner margin, anteriorly or wholly carmine tinged, margined anteriorly by the transverse dark grey line. There is a round suffused blackish-grey spot on the inner margin at four-fifths, in some specimens very conspicuous, in others absent.

|
The posterior surface of the whorls, except for lines of growth, is smooth, with one row of nodules just inside the carina. The columella is not thickened, but somewhat twisted anteriorly. The outer lip is sharply angulated by the carina.George Washington Tryon, Manual of Conchology vol.
|
|
The columella is obliquely trimmed off in front, of a creamy brown, with a thin polished glaze. The axis is not pervious. The siphonal canal is rather deep, flaring a little anteriorly. Dall, W.H. (1890) Scientific results of explorations by the U.S. Fish Commission Steamer Albatross.
|
|
The rhinarium is bare, with an obtuse, triangular projection. Eyes are small and placed anteriorly. A short, broad rostrum for exhaling and a long, broad cranium define the relatively flat skull. The North American river otter's nostrils and ears close during submersion, keeping water from entering them.
|
|
The function of the pectoralis major is different for its different heads. The clavicular head flexes the humerus, and the sternocostal head adducts the humerus. As a whole the action is to adduct and medially rotate the humerus. It also draws the scapula anteriorly and inferiorly.
|
|
This sculpture becomes obscure toward the siphonal canal. Above the periphery is one well- marked cingulum slightly turretting the whorl which inclines from it to the suture in a flattened manner. The aperture is pointed in front, wider behind. The columella is simple, perfectly straight, anteriorly attenuated.
|
|
The length of an adult shell varies between 4.5 mm and 6 mm; its diameter 2.2 mm. (Original description) The narrow, fusiform shell is truncated anteriorly. The aperture measures one- third the length of the shell. The shell contains 9 whorls, of which the protoconch forms four.
|
|
Abduction of the thumb is defined as the movement of the thumb anteriorly, a direction perpendicular to the palm. The abductor pollicis brevis does this by acting across both the carpometacarpal joint and the metacarpophalangeal joint. It also assists in opposition and extension of the thumb.
|
|
Scutellum well developed; not abruptly elevated, or abruptly elevated; anteriorly simple; posteriorly broadly rounded or obtusely angulate, or truncate. Mesoscutum without stridulatory file.

|
|
The antitragus is a feature of mammalian ear anatomy. In humans, it is a small tubercle on the visible part of the ear; the pinna. The antitragus is located just above the earlobe and points anteriorly. It is separated from the tragus by the intertragic notch.
|
|
The aperture is pear-shaped, rather narrow posteriorily, and somewhat effuse anteriorly. The posterior angle is rendered obtuse by the tabulation. The outer lip is thin. The columella is short, curved, slightly reflected, reinforced by the attenuated base and provided with a weak fold at its insertion.
|
|
At either posterior angle of the hard palate is the greater palatine foramen, for the transmission of the descending palatine vessels and greater palatine nerve; and running anteriorly (forward) and medially (towards the center-line) from it is a groove, for the same vessels and nerve.
|
|
The wingspan is about 45 mm. The forewings are fulvous with almost obliterated transverse linear fasciae, the first practically obsolete and not anteriorly recurved, the second a little more distinct. The hindwings are croceous (deep redish yellow) without black spots on the abdominal area.Distant, W. L. 1903.
|
|
The size of the shell attains 20.4 mm. (Original description) The fusiform shell is acuminated at both ends. Its color is pale fulvous, obscurely spotted with brown, here and there tinged with light purple, and coloured anteriorly with a purplish band. The spire is acute, gradately turreted.

The retroinguinal space (or Bogros' space) is the extraperitoneal space situated deep to the inguinal ligament. It's limited by the fascia transversalis anteriorly, the peritoneum posteriorly and the iliac fascia laterally. This preperitoneal space communicates with prevesical space of Retzius. It is divided into two compartments.
|
|
They have relatively long hind legs for jumping. The dog flea can be distinguished from the very similar cat flea by its head, which is anteriorly rounded rather than elongate, and the tibiae of its hind legs, which exhibit eight setae-bearing notches rather than six.
|
|
Neural tube closure is not entirely understood. Closure of the neural tube varies by species. In mammals closure occurs by meeting at multiple points which then close up and down. In birds neural tube closure begins at one point of the midbrain and moves anteriorly and posteriorly.
|
|
These compound eyes are the main optical sense organ in adult brine shrimps. The median eye, or the naupliar eye, is situated anteriorly in the centre of the head and is the only functional optical sense organ in the nauplii, which is functional until the adult stage.
|
|
Above the lirae are coarse, smooth, and generally irregularly spaced. The interstices are smooth, as wide or wider than the ribs. Below they become more finely lirate The body whorl is well rounded and deflected anteriorly. The rounded aperture somewhat contracted, oblique, and pearly white within.
|
|
The forewings are light grey, mixed with white and with some scattered black scales. There is a streak of black suffusion from the base of the costa. The first line is white, edged with black suffusion posteriorly. The second line is white, edged with black anteriorly.
|
|
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 stylet is 100-140 micrometers long; it is very thin and flexible with rounded knobs. The excretory pore is posterior to median bulb. The esophageal gland is lobe-like and extends anteriorly over the intestine. The tail is 115-189 micrometers long with a rounded terminus.

Gondwanatitan had vertebral lateral fossae that resembled shallow depressions. Fossae that similarly resemble shallow depressions are known from Saltasaurus, Alamosaurus, Malawisaurus, and Aeolosaurus. Its middle tail vertebrae's neural spines are angled anteriorly when the vertebrae are aligned. These vertebrae resemble those of Cedarosaurus, Venenosaurus, and Aeolosaurus.
|
|
This is the type genus of the family, and has two species, O. coalescens, and O. latissima. O. coalescens resembles a hot water bottle with dorso-anteriorly positioned small eyes flanked by preorbital openings, and a prominent dorsal spine, while O. latissima is extremely broad in comparison.
|
|
Face is conspicuously produced anteriorly, lower face is shining black. Eyes are reddish brown. The third segment of the antennae is long and strap-like. Wings are hyaline, with few brown patches, mainly a partly brown costal cell and a rounded or band-like apical spot.
|
|
It has a thick, heavy shell intermediate between saddle-backed and domed, and not appreciably narrowed anteriorly. Males are larger and more saddle-backed; females are more domed. Until eradication programs, virtually all nests and hatchlings were destroyed by black rats, pigs, dogs, and cats.MacFarland 1974a.
|
|
Along the midline of the animal is a white patch that matches the white border. This patch sometimes encircles the gills and extends anteriorly between the rhinophores. The line is often broken into two patches anterior-posteriorly. The rhinophores and branchia (gills) have an orange-red tint.
|
|
It is marked by five almost equal and equally spaced spiral cords and two very slender lirations, the latter near the columella. The deep grooves between the spiral cords are marked by numerous slender axial lirations. The sutures are subchanneled. The aperture is irregular, somewhat channeled anteriorly.
|
|
The base of the body whorl is well rounded. It is marked by six spiral cords which are of unequal strength, separated by grooves of different widths, which are crossed by fine axial threads. The aperture is oval, and effuse anteriorly;. The posterior angle is obtuse.
|
|
The protoconch smooth. The height of the spire equals about that of the aperture with siphonal canal. Sculpture : Each whorl is tabulated below the suture, and the tabulation ends anteriorly in a prominent spiral thread. Then follows a second tabulation, terminating in a row of oval gemmules.
|
|
The tendons of the extensor pollicis longus and extensor pollicis brevis form what is known as the anatomical snuff box (an indentation on the lateral aspect of the thumb at its base) The radial artery can be palpated anteriorly at the wrist(not in the snuffbox).
|
|
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.

The siphonal canal is nearly straight, a little prolonged, distinctly constricted at its base by the incurvature of the outer lip. The columella is straight, tapering anteriorly, its inner edge forming a well-marked sigmoid curve. The epidermis is indistinct. The color of the shell is translucent bluish white.
|
|
The outer lip is sharp, simple, arched well forward, especially anteriorly. The body is without callus. The columella is thin, white, short, slightly twisted. The siphonal canal is short, very wide and hardly differentiated Dall, W.H. (1890) Scientific results of explorations by the U.S. Fish Commission Steamer Albatross.
|
|
They are somewhat irregularly waved and concave anteriorly. The shell shows an evanescent spiral strife, not always visible, and eight or ten spiral raised threads on the anterior third of the body whorl. The body whorl is otherwise smooth. The notch is deep, rounded and leaving no fasciole.
|
|
The body whorl descends anteriorly and is very broad. The oval aperture is finely sulcate within. It is nacreous, the predominant color being silvery or pinkish. The columella is a little expanded above, over a minute umbilical chink and surrounded by a crescentic opaque white, sharply defined tract.
|
|
The flanks are brownish black anteriorly and light greyish-brown posteriorly. Foot-flagging has not been observed in this species, presence of flashy colouration on dorsal surface of the hind limb together with the degree of webbing and habitat preference suggest that it might nevertheless possess this behaviour.
|
|
Fossils discovered later, nevertheless, showed that this was a toothed whale. In extant odontocetes, however, the dentition is atavistic with all teeth reduced to simple, undifferentiated conical shapes. In squalodonts the teeth resemble those of the archaic whales, Archaeoceti, with conical incisors anteriorly and low-crowned, serrated teeth posteriorly.
|
|
This saddle-backed species is one of the smallest of the Galápagos tortoises. Its brownish-gray, oblong carapace has only a very shallow cervical indentation, the anterior marginals little to much upturned, and the slightly serrated posterior marginals flared and upturned. The carapace is usually compressed or narrowed anteriorly.
|
|
An epispadias is a rare type of malformation in which the urethra ends, in males, in an opening on the upper aspect of the penis, and in females when the urethra develops too far anteriorly. It occurs in around 1 in 120,000 male and 1 in 500,000 female births.
|
|
The forewings are pale brownish-ochreous, irrorated with dark fuscous or blackish on the veins. The first line is white, suffused with whitish anteriorly and margined with dark posteriorly. The second line is white and there is a hindmarginal row of black dots. The hindwings are ochreous-grey- whitish.

|
|
The tentacles are very close to the edge of the mouth. The head is slightly widened around the jaw angle and narrows anteriorly. The body has 312–318 annuli in total. The annular grooves are dorsally complete but narrowly separate ventrally, except for the last one tenth of body.
|
|
In birds, the PGCs arise from the epiblast and migrate to anteriorly of the primitive streak to the germinal crest. From there, they use blood vessels to find their way to the gonad. The CXCR4/Sdf1 system is also used, though may not be the only method necessary.
|
|
Ovulinae typically have either an ovate (egg-shaped), lanceolate (lance-shaped) or pyriform (pear- shaped) shell. The spire is not prominent, and the funiculum is absent. The anal canal is twisted anteriorly. The extremities are usually short and the outer lip of the aperture has well-developed teeth.

|
Chenoprosopus milleri skull The skull is long and narrow broadly rounded anteriorly with the sides diverging slightly and regularly in the anterior four-fifths of the length. The orbit of Chenoprosopus milleri is nearly round and is about 32 mm. in diameter. It is smaller than Nigerpeton ricqlesi.
|
|
The sulcus is like the rest and is similarly sculptured. The base of the shell is well rounded, somewhat attenuated anteriorly, sculptured like the spaces between the sutures, having seven spiral keels. These keels diminish somewhat in size from the periphery to the umbilical area. The aperture is subovate.
|
|
Most notable of this specialization is the hindlimb morphology. The pelvic girdle consists of a small pubis and an ilium with anteriorly extensive but posteriorly rudimentary processes. The femoral head is offset from the bone, forming an s-shape, and the attachments for the ilio-femoralis muscles are significant.
|
|
Of the four engines, two were positioned in tandem, centrally to the cell above the fuselage, while each of the other two were positioned anteriorly, on the wings. The engines were started by compressed air, produced by a compressor unit located under the seat of the right hand rider.
|
|
Adults exhibit seasonal dimorphism. The summer form has pale orange forewings with brown scales scattered on the upper quarter of the costa. The costa is pale yellow anteriorly. There are two dark discal spots, one at the middle and a larger one at the end of the cell.
|
|
The eyes are small, dorsolaterally located, and under the skin (subcutaneous). The maxillary barbels do not extending beyond the head. The dorsal fin spine is serrate anteriorly and smooth posteriorly. S. chennua, S. rheophilus, and S. torosus grow to about SL. S. rabdophorus attains a length of about SL.
|
|
Two occipital knobs on each side. Tympanum small, one- > fourth or one-third the length of the palpebral border in diameter. Paratoid > gland small, rounded, lateral, studded with warts; the dorsal region is > similarly studded, most abundantly anteriorly. Sides, extremities and gular > region covered with smaller warts; belly areolate.
|
|
The body whorl scarcely descends anteriorly, above with 6 to 8 spiral closely granose cinguli, beneath with 7 to 9 similar concentric cinguli. The interstices both above and below are closely, sharply, obliquely, microscopically striate. The base of the shell is slightly convex. The oblique aperture is tetragonal.

Ziapelta sanjuanensis showed three unique derived traits or autapomorphies. The middle bone plate, caputegula, of the snout was large, prominent and roughly triangular in shape. Ziapelta had deep, anteriorly curved squamosal horns (measuring from the base to the tip). The rear base of the skull featured three deep grooves.
|
|
It then repeatedly swings its head in a small arc, raking its teeth downward in strokes. A second mode in which Sicyases sanguineus feed on them is to insert its teeth on the limpet's shell and then twist. This produces a characteristic break into the shell posteriorly and anteriorly.
|
|
The forewings are dark violet grey, suffusedly irrorated (sprinkled) with dark fuscous and with an obscure cloudy darker spot representing the second discal stigma, edged anteriorly by a small roundish ochreous-whitish spot. The hindwings are grey, darker towards the apex.Annals of the South African Museum. 17 (4): 285.
|
|
Duodenal ulcers are more common than gastric ulcers and unlike gastric ulcers, are caused by increased gastric acid secretion. Duodenal ulcers are commonly located anteriorly, and rarely posteriorly. Anterior ulcers can be complicated by perforation, while the posterior ones bleed. The reason for that is explained by their location.
|
|
Abdomen covered with white feathery waxy excrescences. The frons is longitudinally convex, genae anteriorly rotundate, neither frons nor genae produced in the middle. Ocelli distinct. Antennae: segments of the peduncle elongate, first extending considerably beyond the lateral margins of the genae, second about one-fifth longer than the first.
|
|
Both common iliac arteries are accompanied along their course by the two common iliac veins which lie posteriorly and to the right. Their terminal bifurcation is crossed anteriorly by the ureters. This is significant as the bifurcation of the common iliac artery is the second point of ureteric constriction.
|
|
The forewings are ochreous white with a narrow dark fuscous costal streak from the base to near the apex, finely attenuated anteriorly. There is a moderate dark fuscous streak along the dorsum from one-fourth to the tornus, narrowed towards the extremities. The hindwings are whitish ochreous, posteriorly infuscated.
|
|
The aperture is oval, effuse anteriorly. The posterior angle is obtuse; The outer lip is thin. The inner lip is very oblique, slender, curved, and decidedly reflected, but not appressed to the base. The columella is provided with a moderately strong fold a little anterior to its insertion.
|
|
The third vertebral is considerably longer than broad, subquadrangular, and its posterior border is straight or slightly convex. The fourth vertebral is longest, tapering anteriorly and forming a narrow suture with the third. The fifth vertebral is much broader than the others. The large plastron is feebly angulated laterally.
|
|
The splenial is preserved only at the joint, forming a bulge on the ventral margin. It is inferred then that the intramandibular joint is situated far anteriorly. This resembles that of Pachyrhachis. The tooth row extends the same length as exhibited in the upper jaw for equal alignment.

The Pacific crevalle jack is distinguished by yellow anal and caudal fins The Pacific crevalle jack is a relatively large fish, growing to a maximum recorded size of 101.6 cm in length and 19.7 kg in weight. It is similar to most other jacks of the genus Caranx, having a moderately deep and compressed, oblong body, with the dorsal profile more convex than the ventral profile, particularly anteriorly. The dorsal fin is in two distinct sections; the first consisting of eight spine and the second of one spine and 19 to 21 soft rays. The anal fin consists of two anteriorly detached spines followed by one spine and 16 to 17 soft rays.
|
|
The forewings are white with three suffused blotches of fuscous irroration, sprinkled with black specks, occupying most of the disc from near the base to near the apex, separated only by curved white streaks, the first blotch extending below the fold and indistinctly to the costa, the second extended anteriorly to the costa at two-fifths and limited beneath by the fold, the third resting on the tornus and not reaching the costa. There is some slight dark fuscous irroration towards the middle of the dorsum and a narrow yellow- ochreous apical fascia attenuated downwards to the middle of the termen, the edged anteriorly with some dark fuscous irroration. The hindwings are grey.
|
|
The bigeye trevally is one of the larger members of Caranx, growing to a maximum recorded size of 120 cm in length and 18.0 kg in weight. It is similar to most other jacks in having a compressed, oblong body, with the dorsal profile slightly more convex than the ventral profile, particularly anteriorly. The snout is slightly pointed, and is greater in length than the eye diameter. The dorsal fin is in two distinct sections; the first consisting of 8 spine and the second of 1 spine and 19 to 22 soft rays. The anal fin consists of 2 anteriorly detached spines followed by 1 spine and 14 to 17 soft rays.
|
|
The forewings are fuscous irrorated (sprinkled) with whitish and with a dark brown patch irregularly irrorated with blackish extending along the costa from one-third to near the apex, and reaching more than halfway across the wing, limited beneath before the middle by a large tuft of scales on the fold. A silvery-grey-whitish line crosses the wing at five-sixths, on the lower half dilated into a spot preceded and followed by light brownish-ochreous spaces and margined anteriorly by a dark fuscous tuft of scales. There is a silvery- whitish angulated transverse line immediately before the apex. The hindwings are dark grey, thinly scaled and semi-transparent in the disc anteriorly.

|
The most common disorder of a temporomandibular joint is disc displacement. In essence, this is when the articular disc, attached anteriorly to the superior head of the lateral pterygoid muscle and posteriorly to the retrodiscal tissue, moves out from between the condyle and the fossa, so that the mandible and temporal bone contact is made on something other than the articular disc. This, as explained above, is usually very painful, because unlike these adjacent tissues, the central portion of the disc contains no sensory innervation. In most instances of disorder, the disc is displaced anteriorly upon translation, or the anterior and inferior sliding motion of the condyle forward within the fossa and down the articular eminence.
|
|
The forewings are dark grey closely irrorated (sprinkled) with white points or partially suffused with ochreous whitish, especially towards the dorsum anteriorly. There are two spots of black suffusion beneath the costa near the base, alternating with whitish suffusion. There is an ochreous-yellow oblique irregular streak from the costa before the middle, reaching halfway across the wing, and an ochreous-yellow dorsal spot opposite its apex, these margined anteriorly by a curved transverse streak of blackish suffusion which also fills the space between them. An ochreous-yellow transverse spot is found in the disc at three-quarters, connected with the costa by a spot of dark fuscous suffusion, and with a smaller dark fuscous spot adjacent beneath.
|
|
The pelvic fins are short, and fit in fairly pronounced ventral grooves, similar to that of Atropus atropos The lateral line is moderately arched anteriorly, with the curved section containing 57 to 77 scales, while the straight section contains 25 to 43 elements, 11 to 24 of which are weak scutes. Another of the diagnostic traits of the longfin trevally is the scaleless breast, extending from the origin of the pelvic fins to the base of the pectoral fin and anteriorly to the gill cover. There are 24 vertebrae in the species. The longfin trevally's colour is variable with age, although maintains a general colouration of greyish blue above, fading to a whitish silver near the belly region.

Probergrothius sexpunctatus is a species of true bug found in West-Central Africa. The name has been misattributed for many decades to a related species, Probergrothius angolensis, a species that occurs farther to the south, and which feeds on the Welwitschia plant. P. sexpunctatus, as its name suggests, has six prominent black spots on its wings (3 per wing; 2 anteriorly and 1 posteriorly), distinguishing it from the visually similar P. angolensis where the two anterior wing spots are typically fused, making four wing spots (2 per wing; 1 anteriorly and posteriorly). P. sexpunctatus also typically has a reddish pronotum and legs, which are black (or almost black) in P. angolensis, however this character is less reliable.

The scleral flap is then extended to the limbus that is hinged anteriorly. A sclerotomy is then made with a punch followed by a peripheral iridectomy. An 8-0 nylon suture is then passed through the conjunctiva from the external aspect into the subconjunctival space. This process creates the cheesewiring effect.
|
|
In addition, they are tilted at 45 degrees and positioned more anteriorly than a human's vocal folds. The heart of an elephant weighs . It has a double-pointed apex, an unusual trait among mammals. In addition, the ventricles separate near the top of the heart, a trait they share with sirenians.

The forewings are whitish ochreous suffusedly irrorated (sprinkled) with fuscous and with some irregular dark fuscous markings towards the base, on the dorsum forming a suffused patch extending to one-third. There is a narrow oblique dark fuscous fascia from the costa about one-third, not reaching the dorsum, anteriorly edged by a whitish line continued on the dorsum around its lower extremity, posteriorly suffused. There is also an elongate dark fuscous mark in the middle of the disc, with crescentic whitish edging above. A trapezoidal dark fuscous blotch is found on the costa about three-fourths, narrowed downwards, anteriorly edged whitish, and posteriorly by an inwards- oblique whitish line continued to the dorsum before the tornus, followed in the middle by a blackish dash.
|
|
The forewings are fuscous with a rather broad light ochreous- yellow dorsal stripe throughout, the edge is broadly prominent at about two- thirds, where it reaches halfway across the wing, narrowed towards the tornus. There is a curved dark grey line from four-fifths of the costa to the tornus, edged anteriorly by a light greyish line becoming stronger and white towards the costa, preceded towards the costa by an obscure ochreous dark-edged line. The area beyond this is light ochreous yellow, marked on the upper part of the tornal prominence with a dark bronzy spot containing a round black dot, the apical projection is suffused with grey and contains a white longitudinal mark. The hindwings are grey, lighter anteriorly.

The short, sharply curved front section of the lateral line and blue spots distinguish the species The bluespotted trevally is a moderately large fish, growing to a known maximum length of 66 cm. It has a body shape characteristic of many of the larger species of Caranx, possessing a strongly compressed, oblong form with the dorsal profile, particularly anteriorly, much more convex than the ventral profile. The dorsal fin is in two distinct sections, the first consisting of eight spines while the second has one spine and 18 or 19 soft rays. The anal fin consists of two detached spines anteriorly followed by one spine and 15 to 17 soft rays, while the pelvic fin has 1 spine followed by 18 soft rays.

Hindeodus is characterized by a P element with a large cusp, denticles that increase in width anteriorly (toward the head) except for the anterior-most denticle and generally decrease in height anteriorly, except for the posterior-most three denticles (the ones furthest back) which are at equal heights. Their cusps are much higher than denticles, and they possess S elements with a short lateral processes that are slightly upturned laterally with denticles of variable size. Hindeodus is differentiated from other conodonts by having P elements with large fixed cusps located at the anterior end of the blade and usually grow primarily by adding new denticles only to the posterior end of the element. Other conodonts vary in growth pattern and location of their cusps.

|
The length of the shell attains 4 mm. (Original description) The short shell has a fusiform shape. Its color is orange or wax yellow, white along the upper part of the whorls and anteriorly. It shows very strong transverse ribs, about nine on each whorl, smooth on the summits, with unequal microscopic spiral elevated lines.
|
|
However, females are bigger and have a uniformly dark, saddle-like coloration, while males have spotty colorations. The pelages of the young transform through a series of colors during maturation. The undersides of black-spotted cuscuses have areas of yellow and white. Females possess four mammae and modified pouches for neonates that open anteriorly.
|
|
Platyceras has a distinctive, curved conical shape that is easily recognized. The cap-like shell is high and broad anteriorly. The posterior portion of the shell, at the apex, is usually slightly coiled in an asymmetrical fashion. Frequently, the front portions of the shells are broken, though the posterior sections are relatively well preserved.
|
|
The aperture is short and broad, widely open anteriorly, with scarcely any contraction for a siphonal canal. The outer lip is simple, rounded, with a deep notch at the suture.

|
Their centra begin as cylindrical, but become flattened closer to the pelvis. No neural arches are preserved in any dorsal vertebrae. Zygapophyses are weakly present, unlike in the cervical vertebrae, but the inter-arch articulations are still absent. The transverse processes are directed slightly anteriorly and dorsally, and become less pronounced towards the pelvis.
|
|
The forewings are white, sprinkled with ochreous brown and black. The basal area is ochreous brown, suffused with black and cut by a narrow white transverse line midway between the base and the first line. This first line is margined by black posteriorly, except in the middle. The second line is black margined anteriorly.
|
|
The posterior sinus is as broad as the subsutural band and rather shallow. The outer lip is considerably inflated, curving gradually toward the columella without forming a decided siphonal canal. The columella is nearly straight, curved slightly anteriorly, with a narrow, closely adhering strip of enamel. The suture is distinct, undulating and slightly channelled.

|
The supratrochlear artery branches from the ophthalmic artery and passes anteriorly through the superomedial orbit. It travels medial to the trochlear nerve. With the supratrochlear nerve, the supratrochlear artery exits the orbit through the supratrochlear notch (variably present), medial to the supraorbital foramen and its artery and nerve. It then ascends on the forehead.
|
|
Sarcophagidae larvae are white or pale yellow, cylindrical, and tapered anteriorly. All segments beyond the first have anterior and posterior bands of hairs. The mandibles are usually strong and curved, resembling a hook. Posterior spiracles are sunken in, which is a characteristic that can be used to distinguish between flesh fly and blow fly larvae.
|
|
There were typically five rows of spines, increasing in size anteriorly. The front spine was much larger, around 28 centimeters long, and was recurved. The fourth spine varies in length in each specimen, but remains shorter than the fifth in all of them. Desmatosuchus are the only aetosaurs known to have possessed spines like these.
|
|
Three distinctive characteristics were detected on the M. averyi specimen that separated the two species from one another. The greatly enlarged anterior emargination of the external nostrils were more anteriorly placed. The APV were widely separated without the prong of the premaxilla like M. casei. And there was a medial subrostral fossa in the premaxillae.
|
|
The metastoma is cordated anteriorly and narrowing to a rounded posterior. In 1971, E. serricaudatus and E. carinatus from the Early Wenlock age in Sweden were described by Kjellesvig-Waering. They were the only pterygotids in the area. The holotype of E. serricaudatus consists of the fixed ramus with acute termination of a large chelicera.

The uterine artery usually arises from the anterior division of the internal iliac artery. It travels to the uterus, crossing the ureter anteriorly, to the uterus by traveling in the cardinal ligament. Uterine artery It travels through the parametrium of the inferior broad ligament of the uterus. It commonly anastomoses (connects with) the ovarian artery.
|
|
Ladin's sign is a clinical sign of pregnancy in which there is softening in the midline of the uterus anteriorly at the junction of the uterus and cervix. It occurs and is detectable with manual examination at about 6 weeks' gestation.Alan H. DeCherney, Martin L. Pernoll, Lauren Nathan. Current Obstetric & Gynecologic Diagnosis & Treatment, page 196.

|
These snails all have a coiled shell present in their larval stage. But the shell is no longer present in the Pterotracheidae after metamorphosis. The keel (sharp ridge on a whorl of the shell) of the adult shell extends outwards in the Atlantidae and anteriorly in Carinariidae. The shell is calcareous in the Carinariidae.
|
|
Larval stages are poorly known, but those described are slender, narrowed anteriorly, with groups of ventral spicules on creeping welts. The larva is amphipneustic (having only the anterior and posterior pairs of spiracles). The mandibles are simple, hooked, and without additional teeth. The parastomal bars are long, thin structures, fused to the tentoropharyngeal sclerite.
|
|
The periphery of the body whorl is marked by a narrow spiral groove. The base of the shell is well rounded. It is marked by six strong broad rounded almost equal and equally spaced spiral cords, the grooved spaces between which are marked by numerous fine axial threads. The aperture is oval, slightly effuse anteriorly.

Cephalocaridans are found from the intertidal zone down to a depth of , in all kinds of sediments. Cephalocaridans feed on marine detritus. To bring in food particles, they generate currents with the thoracic appendages like the branchiopods and the malacostracans. Food particles are then passed anteriorly along a ventral groove, leading to the mouthparts.
|
|
Pseudecheneis species are easily distinguished among sisorids in having a thoracic adhesive apparatus consisting of a series of transverse ridges (laminae) separated by grooves (sulcae). The dorsal and pectoral fins have one spine each. The head is short and anteriorly depressed with a sharp snout and small mouth. The lips are thick, fleshy, and papillate.
|
|
The forewings are whitish, sprinkled with dark fuscous with a broad clear white longitudinal suffusion extending from the base to three-fourths, anteriorly nearly or quite reaching the costa, posteriorly discal and suffusedly edged above with yellow ochreous. There is sometimes a black basal median dot. The stigmata is raised and black. The hindwings are light grey.
|
|
It is probable that the parabasisphenoid was in contact with the prootic bone, but it was definitely not attached to the opisthotic. Two small foramina, resembling slits, are immediately anterior to the parabasisphenoid- basioccipital suture. They extend anteriorly as canals into the bone and are probably the entrances of the cerebral carotid arteries, although positioned unusually far posteriorly.
|
|
Most of these fibers synapse in the lateral geniculate nucleus or the pretectal nucleus. The crossing of the nasal half of macular fibers of central vision occurs posteriorly in the chiasm. The inferior and superior fibers remain inferior or superior, respectively. However, the inferonasal fibers pass more anteriorly in the chiasm while the superonasal fibers pass more posteriorly.

E pronoe Esp. (= arachne Hbn.) (37 c). Dark black -brown, with a red -brown band which is anteriorly broader and posteriorly narrower and bears costally 2 white-centred ocelli and towards the hindmargin an additional smaller one. The band of the hindwing consists of 3 rounded russet-brown spots with black eye-dots which have occasionally white pupils.
|
|
The axial sculpture consists of (on the body whorl eight) prominent angular ribs with wider interspaces, beginning abruptly at the shoulder rapidly dwindling anteriorly and obsolete on the base. These ribs are crossed by (on the body whorl about 14) widely spaced slender cords, slightly nodulous at the intersections. The aperture is narrow. The anal sulcus is shallow.
|
|
The trophosome can be differentiated between anterior and a posterior area due to incremental changes in host tissue organization, the amount of bacteriocytes, the size and shape of symbionts. The trophosome consisted anteriorly of a small number of bacteriocytes and extensive mesenchyma, while the posterior of trophosome subsequently consisted of a large population of bacteriocytes and a peripheral peritoneum.
|
|
The specific characteristics that distinguish the genus relate to specific anatomical details, with these being a gill raker count between 20 and 31 on the first gill arch, 2 to 4 canines anteriorly positioned in each jaw, and dorsal and anal rays which are never produced into filaments as seen in genera such as Alectis and Carangoides.
|
|
The length of the shell attains 5.3 mm, its diameter 2 mm. (Original description) The dull white shell is high, attenuate anteriorly. It contains six whorls, strongly angular, and including a smooth blunt two-whorled protoconch. A strong keel angles the periphery, another less strong halfway to the lower suture, and a third margins the suture.
|
|
In conjunction with this, the deltopectoral crest (a large flattened structure near the humeral head) is oriented more anteriorly than laterally. Both the humeral head and the tip of the lower extremity of the bone were covered with deep grooves. Just above the lower extremity was a depression, and just lateral to this depression was a distinct ectepicondylar groove.
|
|
The length of the shell attains 24 mm. (Original description) The shell is of moderate size, rather stout, very thin and fragile, delicately tinted with brown below the chestnut-brown tip. It consists of four obtusely shouldered whorls besides the protoconch. The aperture is long, rather broad, pinched in anteriorly, forming a moderately long, narrow siphonal canal.

|
Also, an extended CVD created by a wide opening and big duroplasty can cause a cerebellar "slump". This complication needs to be corrected by cranioplasty. In certain cases, irreducible compression of the brainstem occurs from in front (anteriorly or ventral) resulting in a smaller posterior fossa and associated Chiari malformation. In these cases, an anterior decompression is required.
|
|
The panetals form a suture behind the interparietal; The nuchols are frequently indistinct. The fifth upper labial is below the centre of the eye. The ear-opening is small and oval, with one or two small lobules anteriorly. There are 26 or 28 scales around the middle of the body, all of which are smooth and subequal.
|
|
In human anatomy, the acromion (from Greek: akros, "highest", ōmos, "shoulder", plural: acromia) is a bony process on the scapula (shoulder blade). Together with the coracoid process it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly. It articulates with the clavicle (collar bone) to form the acromioclavicular joint.

The skull was roughly 30 mm long and 12 mm tall. The eyes were large and the snout was narrow. Towards the tip of the snout were two small premaxillary teeth, which were separated by a diastema from at least 22 small maxillary teeth. The orbits were directed anteriorly, suggesting that Megalancosaurus had good binocular vision.

Mesoceras is a mid Silurian discosorid from central Europe named by Barrande in 1877, with a short, anteriorly contracted body chamber and an aperture that is a long transverse slit. (Teichert 1964). The cross section is slightly oval with the dorso-ventral dimension slightly less than the lateral. Sutures are straight and transverse, the siphuncle is subcentral.
|
|
The palps of the male have a dorsally directed patellar apophysis, which is nearly as long as male's palpal tibia. The epigyne has a reddish-brown median part, and is broadly rounded anteriorly. The body colour is dark brown, with a whitish pattern on the dorsum. The legs are black, with bright hairs and strikingly robust spines.
|
|
Due to the small interbracket distance in the lingual braces, compare to the buccal braces, compensatory bends which can be made in finishing phase are tough to create. The distance between brackets anteriorly in lingual braces is about 40% smaller than the buccal braces. Despite the bends, making loops to close spaces also becomes mechanically tough.
|
|
Paleognathes are named for a characteristic, complex architecture of the bones in the bony palate. Cracraft (1974) defined it with five characters. # The vomer is large and articulates with the premaxillae and maxillopalatines anteriorly. Posteriorly the vomer fuses to the ventral surface of the pterygoid, and the palatines fuse to the ventral surface of this pterygovomer articulation.

They become obsolete upon the base of the body. The spirals are low, flattened, and rather obscure, usually 3 upon the antepenultimatwhorl 15 upon the ultima, the 6 upon the columella are slightly more elevated than those upon the body. Ssecondaries are fortuitously introduced upon the base of the body. The fasciole exhibits an obscure spiral liration anteriorly.
|
|
The base of the shell is well rounded. It is marked by four low, broad cords and seven exceedingly fine incised lines, the latter about the umbilical area. The narrow, strongly incised grooves which separate the cords are crossed by numerous fine axial threads, which give them a pitted appearance. The aperture is oval, and slightly effuse anteriorly.
|
|
It is marked by twelve slender, spiral cords which are a little wider than the spaces that separate them and become successively narrower and more closely spaced from the periphery to the umbilical area. The spaces between the cords are marked by numerous slender, axial threads. The aperture is pyriform, and slightly effuse anteriorly. The posterior angle is acute.
|
|
Peirosaurus has a ziphodont dentition that is somewhat heterodont, with conical premaxillary teeth and serrated maxillary and posterior mandibular teeth. The rostrum is laterally compressed with a grove between the maxilla and premaxilla to accommodate for an enlarged mandibular tooth. A maxillary wedge-like anterior process is also present. The external nares face slightly forward and anteriorly protrude.

The family Monstrillidae is characterised by having a well-developed fourth pair of swimming legs, but a rudimentary or absent fifth pair. Adults have no oral appendages, and the mouth leads only to a short, blind pharynx. They also lack second antennae, but show large, multiramous and setatious antennulae. These antennulae are rigid and anteriorly oriented.
|
|
The forewings are white, suffused with light greyish fuscous or yellowish fuscous, and irregularly irrorated (sprinkled) with black. There is a short thick interrupted cloudy blackish streak from the base of the costa. The first line is whitish, margined by triangular black spots posteriorly on the costa and inner margin. The second line is white, anteriorly dark-margined.
|
|
Aperture narrow to broad, usually wider anteriorly. Lip slightly to distinctly thickened, flared posteriorly in some species, smooth on inside edge to weakly denticulate, lacking lirae, external varix absent. Shell lacking a siphonal notch and posterior notch. Shell with weak parietal callus wash or weak parietal callus deposits in some species, but lacking collabral parietal callus ridge.

The triclads are characterized by triply branched intestine and anteriorly situated ovaries, next to the brain. Today the order Tricladida is split into three suborders, according to their phylogenetic relationships: Maricola, Cavernicola and Continenticola. Formerly, the Tricladida was split according to habitats: Maricola, which is marine; Paludicola, which inhabits freshwater; and Terricola, which is land- dwelling.Hallez P. (1892).

|
The intercentra of the region where the vertebral column contacts the shoulder girdle are flat anteriorly and posteriorly. The neural arches have almost vertically set prezygapophyses (vide postcervical vertebrae). This suggests that in this region the lateral bending of the vertebral column was very limited. It was probably connected through articulation of the vertebral column with the shoulder girdle.
|
|
Elements of Ctenopterus (1-7) Stylonurids, which lived from the Ordovician to Lower Permian periods, were small to very large forms with scales developing into tubercules and knobs. The prosoma (head) exhibited variable shape, with arcuate compound eyes located subcentrally, or anteriorly. Their abdomens were slender. Their walking legs were long and powerful, sometimes characterized by spines.

The sculpture consists of narrow spiral riblets with interstitial smaller threads. The interstices are finely latticed by raised close longitudinal striae. The spire contains about four whorls with the last 1½ very rapidly widening, descending anteriorly. The large aperture is oblique, oval, lightly sulcate within and brilliantly iridescent, with red, skyblue and green reflections, neither predominating.
|
|
The spire is conoidal with scarcely convex outlines. The about 6 whorls are somewhat convex and separated by well impressed sutures. The body whorl is large and deflected anteriorly. It bears 18 or 19 crowded, closely granose cinguli, of which the 1st, 3d, 5th, 7th, 9th and two upon the base are composed of alternate black and white granules.
|
|
The about 6 whorls are slightly convex, and spirally lirate. The body whorl is encircled by about 14 granose separated lirae, of which about 6 are on the upper surface, their interstices bearing spiral stripe. The body whorl is obtusely angular at the periphery, slightly convex beneath, a little descending anteriorly. The aperture is rounded-tetragonal.
|
|
It contains about 6 whorls. The upper ones are nearly fiat, the penultimate and last convex, the former with 7 or 8 spiral distinctly granose lirae, the last with about 18, of which the 7th usually is upon the periphery. The intersticesare finely obliquely striate. The body whorl is deflected anteriorly, and rounded at the periphery.

Restoration Cistecephalus was one of the most atypical dicynodont genera. However, it was broadly similar in anatomy to other cistecephalids, all of which share similar adaptations to digging. Its skull was broad, with laterally-directed temporal openings and a sharply tapering snout, similar to extant fossorial animals. However, it has relatively large, anteriorly-directed orbits, suggesting binocular vision.

The upper tooth row of Neoaetosauroides runs anteriorly to the tip of the elongated snout, evidence that is incompatible with the theory of a keratinous beak proposed for other aetosaurs.Desojo, J. B. and Báez, A. M. (2007). Cranial morphology of the Late Triassic South American archosaur Neoaetosauroides engaeus: evidence for aetosaurian diversity. Palaeontology 50(1):267-276.

The forewings are dark violet grey with a narrow ochreous-yellow fascia near the base, with projections outwards on the costa and in the disc, anteriorly blackish edged on the costa and with two blackish tufts rather obliquely placed in the disc about one-third. The hindwings are dark grey.Transactions of the Entomological Society of London. 1914: 234.

|
It is smooth and subtriangular, its apex directed posteriorly and it ends at the foramen magnum. Its sides are delimited anteriorly by short parietal crests. Particularly useful externally is the interorbital crest shape. In Anaxyrus hemiophrys the posterior ends of the crests almost invariably diverge at least slightly where they join the postorbital crests (usually not evident externally).

Westergaardites is an Upper Cambrian trilobite that is known from the Eastern Tian Shan (Central Asia). It is related to Triarthrus, but can easily be distinguished from it by an extremely long exoskeleton, anteriorly placed eyes, a thorax of 19 segments with an extremely wide axis, and very narrow pleural regions, pleural spines, and a pygidium with marginal spines.
|
|
The mesial margin of some of its teeth have a pronounced distal curvature. Additionally, its palatines are strongly convex with a pronounced ridge along the midline. In palatal view, the palatine width narrows anteriorly from the suborbital fenestrae to the midline, in a distinct elongate triangular shape. The maxillopalatine suture midline terminus is level to the fourth maxillary alveolus.
|
|
Cell division adds to the length produced by convergent extension. Some of the cells from the anterior portion of the epiblast contribute to the formation of Hensen's node. The Hensen's node is the organizer for gastrulation in the vertebrate embryo. Simultaneously, the secondary hypoblast (endoblast) cells continue to migrate anteriorly from the blastoderm's posterior marginal zone.

Spatalistis aglaoxantha is a species of moth of the family Tortricidae. It is found in China (Sichuan, Zhejiang).Spatalistis at funet The wingspan is about 16 mm. The forewings are bright clear yellow with two or three small ferruginous dots towards the dorsum anteriorly and an irregular violet-fuscous costal band becoming reddish-ochreous on the posterior half.
|
|
The species in the family Percohidae are elongated, benthic fishes with an anteriorly depressed head, a broad flat snout which gives rise to the common name duckbills. The mouth is large with a prognathous lower jaw and exposed maxilla. They have large closely placed eyes. There are two spines on the opercula and one on subopercule.
|
|
The auriculotemporal nerve passes between the neck of the mandible and the sphenomandibular ligament, gives off parotid branches and then turns superiorly, posterior to its head and moving anteriorly, gives off anterior branches to the auricle. It then crosses over the root of the zygomatic process of the temporal bone, deep to the superficial temporal artery.
|
|
Males measure and females in snout–vent length. Dorsum is olive-brown with dark brown dorsal blotches and flanks with a dark brown stripe. There are oblique lateral stripes extending from anterior corner of the eye to the groin, with cream and golden traces, olive-tan anteriorly. Two small golden glands are at each side of the eye.
|
|
Scales are small and present from the primary annulus 175. Coloration is uniform lavender, becoming lighter anteriorly and ventrally. The coloration is caused by tiny, closely spaced pinkish-cream punctate glands on darker background; when these become closer together and eventually fuse, they give rise to the more pinkish appearance of the head and ventral region.
|
|
The orbits are oriented anterodorsally, facing upward and slightly forward. The dentition of Cerrejonisuchus is generally homodont, although the third maxillary tooth is enlarged and the fourth is somewhat smaller than the rest. They are conical, labiolingually compressed, each having a relatively rounded apex. The carinae, or tooth edges, are strongly developed both anteriorly and posteriorly.
|
|
Weak supratympanic folds are present. Another pair of more or less distinct skin folds starts near the eyes, converge in the scapular region, and then diverge and fade out. Preserved specimens are dorsally gray to light tan. A dark mark above the posterior edge of the tympanum is usually present, sometimes continuing anteriorly as an ill-defined postocular streak.
|
|
The outer lip is rather thick, not showing the external sculpture within. The columella is somewhat twisted, revolute anteriorly, re-enforced by the attenuated base, and provided with a weak fold at its insertion. The parietal wall is covered by a callus—which joins the columella with the posterior angle of the aperture and renders the periostracum almost complete.
|
|
Polyeunoa laevis has 75 segments, with 15 pairs of elytra. the dorsum is covered with numerous dark brown cross lines on every segment that are especially dense anteriorly. The lateral antennae inserted ventrally (beneath prostomium and median antenna). The notochaetae can be distinctly thicker than the neurochaetae, or about as thick as the neurochaetae, with bidentate neurochaetae absent.
|
|
The uterine isthmus is the inferior-posterior part of uterus, on its cervical end — here the uterine muscle (myometrium) is narrower and thinner. It connects superiorly-anteriorly to the complementary parts of the uterus: the body and the fundus. The uterine isthmus can become more compressibile in pregnancy, which is a finding known as Hegar's sign.
|
|
Female upperside: dark brown. Forewing: basal two-thirds brilliant purplish blue, much brighter than the purple sheen in the male. Hindwing: a medial area from base extended outwards for about two-thirds the length of the wing, purplish blue as on the forewing. This colour not extended anteriorly to the costa or posteriorly to the dorsum.

Aeolanthes diacritica is a moth of the family Depressariidae. It is found in India (Assam).Aeolanthes at funet The wingspan is about 19 mm. The forewings are shining white, the costa tinged ochreous anteriorly and with an irregular ferruginous-orange basal spot reaching the costa but not the dorsum, sending a short streak along the fold.
|
|
A black dot is found on the tornus and there is some irregular pale grey irroration (sprinkling) on the apical third, as well as a black dash resting on the termen beneath the apex. The hindwings are grey, thinly scaled and iridescent anteriorly, and with the veins and termen darker.Journal of the Bombay Natural History Society. 22 (1): 161.

|
Chionodes argentipunctella is a moth in the family Gelechiidae. It is found in North America, where it has been recorded from Vermont, south-eastern Ontario, New Jersey, Illinois and Connecticut.Chionodes at funetmothphotographersgroup The wingspan is about 17 mm. The forewings are very dark purplish with a white spot on the costa at the apical third, shaded with black anteriorly.
|
|
The origin of the compressor urethrae muscle is the right and left inferior pubic ramus and it wraps anteriorly around the urethra so when it contracts it squeezes the urethra against the vagina. The external urethrae, like in males, wraps solely around the urethra. Congenital abnormalities of the female urethra can be surgically repaired with vaginoplasty.
|
|
The larva is metapneustic (with only one pair of spiracles, these on the anal segment of the abdomen), but often with vestigial lateral spiracles (rarely apneustic). The head capsule is sclerotized anteriorly and deeply incised ventrally and often dorsolaterally. The mandibles are opposed and move in the horizontal or oblique plane. The abdominal segments have transverse creeping welts.
|
|
Its middle tail vertebrae's neural spines are angled anteriorly when the vertebrae are aligned. These vertebrae resemble those of Gondwanatitan, Venenosaurus, and Aeolosaurus. The related Venenosaurus had unusual lateral fossae, which looked like deep depressions in the outside walls of the vertebral centra. Some fossae are divided into two chambers by a ridge inside the depression.
|
|
The first human case was seen in 1879 in Taiwan. An autopsy was done and adult trematodes were found in the lungs. The adult flukes have a reddish-brown in color with an ovoid shape. They have two muscular suckers, the first an oral sucker located anteriorly and the second a ventral sucker located mid-body.
|
|
Two nearly complete specimens of Oreochima ellioti (specimens AMNH 9910 and AMNH 9916) have an average total length of about 60 mm, with incomplete specimens represent individuals of similar size. The frontals taper anteriorly and were slightly notched where they were in contact with the nasals. The opercular bone was about twice as high as the subopercular.
|
|
The eyes are small to medium. The caudal fin is slightly emarginate to forked, with the lower lobe longer than the upper lobe. The dorsal flap of the iris is present. The lips are wide and fairly thin; the upper lip has small, round papillae and the lower lip has medium-sized papillae anteriorly and smaller ones posteriorly.
|
|
The anal fin has 2 anteriorly detached spines followed by 1 spine and 18 to 20 soft rays. The lateral line has a low anterior arch, with this curved section being longer than the posterior straight section. The straight section contains 20 to 26 scales followed by 11 to 18 small scutes. The breast is completely scaled.
|
|
The shell contains 3½ whorls, including a protoconch of 1½ whorl. The protoconch shows fine spiral grooves, continued on the adult as broad, shallow furrows, which are broadest at the suture becoming smaller and closer anteriorly. On the body whorl are twenty- two spiral ribs, on the penultimate whorl six. The latter are latticed by fine radial riblets.
|
|
The last whorl is with nearly parallel sides, rounded and slightly attenuated base. The columella is stout, strongly twisted, white, short. The outer lip is nearly straight, somewhat thickened, especially anteriorly, not lirate or denticulate internally. The shell is with two revolving ridges, the posterior one is fainter and placed in advance of the middle of the whorl.
|
|
Primitive sauropods had vertebrae that were either flat on both ends (amphiplaty) or concave on both (amphicoely). Venenosaurus may have had a condition intermediate between the two. The possession of amphiplatyan caudal centra with anteriorly facing neural spines is a unique identifier of this species. Sometimes the form of central articulations change within a single individual's vertebral column.
|
|
Anteriorly, it has a pattern of dark crossbands on a light ground color. Posteriorly, the crossbands are replaced by three rows of alternating squarish blotches. The light spaces between the crossbands or blotches are wider than the dark markings. On the belly, the crescent-shaped markings on the ventrals tend to form two stripe-like series.
|
|
Like all insects, harlequin bugs have an open circulatory system. Blood is pumped to the head (anteriorly) through the dorsal blood vessel and posteriorly through the ventral body cavity. To map out the circulation of blood in these insects, Craig et al. injected radioactive phosphorus into the posterior end of the heart and traced it through the body cavity.
|
|
The dorsum has three pairs of longitudinal skin folds anteriorly and four to five pairs posteriorly. The finger and toe tips are bluntly rounded. The toes are about two-thirds webbed. The dorsal colouration consists of rows of black, oblong spots and a broad mid-dorsal light band, with a more or less distinct light vertebral line.
|
|
The supratrochlear nerve branches from the frontal nerve midway between the base and apex of the orbit. It travels anteriorly above the levator palpebrae superioris and exits the orbit through the supratrochlear notch in the superomedial margin of the orbit. It then ascends onto the forehead beneath the corrugator supercilii and frontalis muscles. It then divides into sensory branches.
|
|
The forewings are shining white, with a faint ochreous tinge and a semi-oval leaden-grey spot along the lower half of the termen, edged anteriorly with a dark fuscous line. There are two outwardly oblique dark fuscous lines from the costa towards the apex and a black apical dot, preceded by orange. The hindwings are light grey.
|
|
There is a very broad fascia from the costa beyond the middle to the anal angle, both margins irregularly dentate. A dark-fuscous longitudinal streak is found at the apex, attenuated anteriorly. Between this and the costa is an ochreous-brown area with two white dots on the costa. The hindmarginal part of the disc is irrorated with fuscous.
|
|
They are marked between the sutures by four feebly incised spiral grooves of which the second one above the periphery is the weakest. The periphery of the body whorl is somewhat inflated. The base of the shell is well rounded posteriorly and somewhat attenuated anteriorly. It is marked by four subequal but unequally spaced incised spiral lines.
|
|
There are about 30 of these threads upon the last turn between the summit and the periphery and about 60 on the base. The aperture is very large, patulous anteriorly;. The outer lip is thin at the edge but very thick within. The columella is decidedly curved, and revolute, reinforced to the very edge by the attenuated base.
|
|
Dark brown or black both dorsally and ventrally, with several deep red blotches on the sides anteriorly, rarely along the full length of the body. Similar deep red blotches about the tail. Adults may attain a total length of 38 cm (15 inches). Dorsal arranged in 17 rows at midbody (in 19 rows behind the head).
|
|
The surface is sculptured with numerous alternating larger and smaller spiral threads crossed by fine wavy lines and by irregularly spaced oblique ribs, about twenty in number on the body whorl. The ribs are strongest at the shoulder, gradually disappearing both posteriorly and anteriorly. The shell is somewhat excavated behind the shoulder. The aperture is narrow.
|
|
A narrow band appears about the summit showing its junction with the preceding turn. The periphery and the base of the body whorl is inflated and well rounded. The entire surface of the base and the spire is marked by very fine lines of growth and numerous microscopic wavy spiral striations. The aperture is rather large, somewhat effuse anteriorly.
|
|
The remaining whorls are moderately rounded, with a strong spiral cord at the summit and another one at the periphery, the two being closely appressed at the sutures. The base of the shell is prolonged, marked by low spiral cords. The aperture are irregularly oblong, decidedly effuse anteriorly. The columella is provided with a strong fold at its insertion.
|
|
The wingspan is about 27 mm.Novitates Zoologicae 4: 12 Adults are pale fawn colour, the hindwings pale yellow anteriorly. There are two oblique dark brown lines crossing both wings, between which are three small whate discal spots. There is a pale submarginal line and the exterior border of both wings is defined by a brown line.
|
|
The belly is a yellowish or cream- colored, with diffused, dark mottling along the sides. The head has a dark postocular stripe that extends from behind the eye backwards and downwards to the lip; the back of the stripe touches the angle of the mouth. Anteriorly and posteriorly, the postocular stripe is bordered by distinct white or yellow stripes.
|
|
These factors prevent the expulsion of promastigotes during excretion of the insect. #During 4–7 days the peritrophic matrix is degraded by the activity of chitinases. This release the more actively motile "nectomonad promastigotes" which migrate anteriorly until they reach the opening of the thoracic gut. #Another transformation takes place by which they turn into "leptomonad promastigotes".

Anterior horn shown in red. The anterior horn of the lateral ventricle is also known as the frontal horn as it extends into the frontal lobe. The anterior horn connects to the third ventricle, via the interventricular foramen. This portion of the lateral ventricle impinges on the frontal lobe, passing anteriorly and laterally, with slight inclination inferiorly.
|
|
The majority of the inferior horn's floor is formed by the fimbria hippocampi (from which the fornix emerges), and then, more anteriorly, by the hippocampus itself. As with the posterior horn, the remainder of the boundary - in this case the lateral side of the floor - is directly in contact with the white matter of the surrounding lobe.
|
|
Its sculpture shows a dozen prominent, distant, thin radial ribs descending the last two whorls perpendicularly, broadening at the periphery. These there produce a marked angle to the contour of the shell. The spiral threads lattice the interspaces and denticulate the edges of the ribs. The round aperture adheres anteriorly to the body whorl for a short space.
|
|
Lower incisors are high-crowned and spatulate, and I2 is slightly larger than I1. Size differences between the few preserved lower canines in Sivaladapis suggests possible sexual dimorphism in the genus. P2 is single rooted and caniniform with a honing facet for the upper canine. P3 is double rooted with a prominent protoconid with a paracristid that orients anteriorly.
|
|
On the forewing the patch above the tornus is prominent and in some specimens very large. The antennae are reddish brown and the head and thorax anteriorly are covered with reddish-brown hairs. The upperside of the thorax is grey with white hairs and the abdomen is black. The underside of the head, thorax and abdomen are white.
|
|
Male upperside, forewing: black; a medial triangular area that extends from base outwards to the disc white, suffused at base and anteriorly with iridescent blue that spreads upwards on to the black of the costa; along the dorsum the black ground colour is much paler, in most specimens diffuse fuscous. Hindwing: white, basal third and costal margin broadly suffused with fuscous, the fuscous at base posteriorly overlaid with iridescent blue; a subterminal series of fuscous-black dots and a distinct but very slender black anteciliary line. Underside: white very slightly tinged with bluish; markings all fuscous black, minute and very slender. Forewing: a short discocellular line followed by on anteriorly, strongly curved, discal series of very short detached lines and a more or less obsolescent transverse series of subterminal dots.
|
|
The forewings are leaden grey, sometimes irrorated (sprinkled) with white and with a blackish spot or very oblique mark on the fold about one-fourth. There is a blackish dot in the middle of the disc and an oblique whitish strigula from the costa before the middle, edged on both sides with black, the posterior edging confluent with a dark fuscous fascia preceding the subterminal line, suffused anteriorly and blackish on the costa. The subterminal line from three-fourths of the costa to the dorsum before the tornus is nearly straight and whitish and the terminal area beyond this is more or less whitish irrorated (sprinkled), especially towards the costa, with three or four more or less indistinct blackish pre-marginal dots. The hindwings are dark fuscous, somewhat thinly scaled in the disc anteriorly.
|
|
The forewings are pale ochreous with an irregular blackish patch extending along the dorsum from near the base to near the tornus, widest before the middle of the wing, where it extends halfway across, the edge is sinuate before and beyond this, narrow towards the posterior extremity, the apex truncate and followed by slight whitish suffusion. There is a broad blackish streak along the costa from before the middle to the apex, pointed anteriorly, cut by an oblique whitish strigula at two-thirds and a less oblique grey-whitish strigula at three- fourths, the lower edge between this and the apex semicircularly excavated. There is also an oval silvery-white spot on the middle of the termen containing an elongate black dot. The hindwings are grey, lighter and bluish tinged anteriorly.

The bluefin trevally is a large fish, growing to a maximum known length of 117 cm and a weight of 43.5 kg, however it is rare at lengths greater than 80 cm. It is similar in shape to a number of other large jacks and trevallies, having an oblong, compressed body with the dorsal profile slightly more convex than the ventral profile, particularly anteriorly. This slight convexity leads to the species having a much more pointed snout than most other members of Caranx. The dorsal fin is in two parts, the first consisting of 8 spines and the second of 1 spine followed by 21 to 24 soft rays. The anal fin consists of 2 anteriorly detached spines followed by 1 spine and 17 to 20 soft rays.
|
|
The stigmata are cloudy and dark fuscous, the plical obliquely beyond the first discal, the second discal transverse, edged with whitish anteriorly. There is a small spot of white irroration surrounded with dark fuscous suffusion on the middle of the dorsum and an irregular line of cloudy dark fuscous marks edged anteriorly with white irroration, from two-fifths of the costa very obliquely outwards to beyond the cell, then downwards to the dorsum. A fine dark fuscous streak is found along the costal sinuation and there is an indistinct curved waved fuscous line from three-fourths of the costa to the tornus, the apical space beyond this irrorated with white. A marginal series of cloudy dark fuscous dots is found around the apical part of the costa and termen.
|
|
The forewings are pale ochreous, with a narrowly black base. The costal area is tinged with crimson anteriorly and there is an oblong dark fuscous patch occupying the dorsal two-thirds of the wing from near the base to two-third, followed posteriorly and above beyond the middle by some fuscous suffusion and dark fuscous irroration. The hindwings are light grey.Exotic Microlepidoptera.
|
|
They have "tufted" tails which are brown with white stripes on the sided and the tuft at the end of the tail being dark brown with scattered white hairs. They have large rounded bicolour ears. Their incisors are unique and are used to identify them, they are anteriorly flattened and broad, like chisels, which is where their name comes from.
|
|
The protoconch contains two , homostrophe, convex whorls with 20 fine spiral incisions ending abruptly in a varix. The spire whorls show angulation at one-fourth the distance from the lower suture. They are uniformly concave between the angulations. Their sculpture shows axial ribs, valid, rounded nearly as wide as the interspaces, and spiral lirae, wider anteriorly, wider than their interspaces, crossing the ribs.
|
|
Flattened and spheroid in shape, the torso has a somewhat boxy cross-section. There are sixteen dorsal (back) vertebrae in Tatenectes, which, when articulated, form a considerably flatter arch than seen in related taxa. The dorsal neural spines are inclined anteriorly. The dorsal ribs articulate with the vertebrae horizontally and are deflected backwards, contributing to the flatness of the body.
|
|
The outer lip is thin, curving very gently to join the columella with but a very slight bending in anteriorly, not forming a well-defined siphonal canal. The columella shows a thin, narrow strip of enamel extending its entire length. The suture is inconspicuous. The subsutural band is rather broad, oblique, crossed by delicate slightly curved riblets, most distinct on the upper whorls.
|
|
The pronephros is the first in a sequence of kidneys that form in vertebrate embryos. The pronephric primordium develops from the intermediate mesoderm, lying between the paraxial (somitic) mesoderm and the lateral plate. In many organisms (e.g. amphibians) this primodium forms anteriorly then migrates posteriorly to fuse with the cloaca, while in others it forms along the length of the intermediate mesoderm.
|
|
E. scipio Bsd. (37b). Rather large, the wings narrow and elongate, the distal margin but little curved. The russet-red band of the forewing is interrupted by the veins, being costally rather broad and narrowing posteriorly. There are anteriorly 2 equal-sized white-centred ocelli standing close together and being followed by 2 additional small black ocelli wliich have likewise white pupils.
|
|
The body whorl is subacutely angled above, then a trifle convex at the sides, and being much attenuated anteriorly has a somewhat piriform appearance. It is sculptured with fine lines of growth and transverse indistinct striae or shallow grooves, which around the base are much deeper. The aperture is very narrow. The outer lip is thin and moderately sinuated above the angle.

Libellula semifasciata, the painted skimmer, is an uncommon eastern North American skimmer dragonfly, found from New Brunswick, Canada as far south as Texas and Florida. It is a medium-sized species, at long. Each wing is amber coloured at the base and wing tip and has several brown spots. The abdomen has a lateral strip that is white anteriorly and yellow posteriorly.
|
|
There are ten cervical vertebrae present in A. suessi and none of them are pachyostotic. The shoulder girdle is placed after the tenth presacral and the following vertebrae connect to large, pachyostotic ribs. This can infer that the distinction between the cervical and dorsal vertebrae was between vertebrae 10 and 11. The neural arch is wide with both anteriorly and posteriorly lateral expansions.

Cyphoryctis xylodoma is a moth in the family Xyloryctidae, and the only species in the genus Cyphoryctis. The species and genus both were described by Edward Meyrick in 1934 and are found in Tanzania.funet.fiAfro Moths The wingspan is about 26 mm. The forewings are rather light rufous-brownish with the extreme costal edge yellow-whitish anteriorly, becoming dark fuscous posteriorly.
|
|
The forewings are glossy dark violet fuscous with an oblique ochreous-whitish strigula on the costa at three-fourths and a faint line from this to the tornus. There is an ochreous-yellow streak along the termen from the apex to near the tornus, attenuated downwards, with three acute projecting teeth anteriorly. The hindwings are dark fuscous.Journal of the Bombay Natural History Society.
|
|
The forewings are mixed brownish and dark grey, appearing fuscous, becoming dark fuscous anteriorly, and narrowly along the termen. There is a broad pale greyish-ochreous costal streak from the base to about two-thirds, posteriorly suffused with five or six black specks just beneath the costa and a small black mark at the base. The hindwings are grey.Meyrick, Edward (1916–1923).
|
|
The forewings are ochreous red, deeper towards the costa and inner margin anteriorly. There is a dark fuscous dot in the disc beyond one-third, a second on the fold beneath the middle, a third in the disc at three-fifths, and a fourth between the second and third. The hindwings are pale yellowish ochreous, the apex slightly reddish tinged.

|
Kenyanthropus platyops was singled out by the morphology of the maxilla, characterized by a flat and relatively orthognathic subnasal region, an anteriorly placed zygomatic process and small molars. In other words, the Kenyanthropus had small molars and a flat face which resembled anatomically modern humans. Other features of the Kenyanthropus are thick enamel, steep nasal cavity entrance and moderate mandibular depth.

Morocco: Casablanca, Morocco is notable for being the home of Clinique de Parc, Dr. Georges Burou's clinic for transgender women. Burou is considered one of the pioneers of SRS. A French gynecologist, Burou created the anteriorly pedicled penile skin flap inversion vaginoplasty, still considered the "gold standard" of skin-lined vaginoplasty. He is credited with having performed over 3000 MtF surgeries.

|
Usually it has weak or effaced furrows. The front of the glabella does not touch the furrow that defines the border, permitting the cheeks to join anteriorly in short preglabellar field or these are separated by a depression. As most backward part of the glabella the occipital ring is defined by a furrow. It may or may not carry a backward-directed spine.
|
|
The pelvic fins consists of 1 spine and 17 to 18 soft rays, while the caudal fin is strongly forked and the pectoral fin falcate. The species lateral line is moderately arched anteriorly, with 49 to 50 scales in this section, while the straight section contains 0 to 3 scales and 27 to 36 strong scutes. The breast is completely covered in scales.
|
|
In Type B species, this cone is narrow, and arises only from the base of the basal body. The flagellar apparatus is positioned anteriorly and aids in movement. The exterior of the cell is covered in a thin, unevenly distributed layer of organic filamentous material. These filaments run parallel to the cell and are 1 µm at their thickest point.
|
|
The combination of these two elements gives to the surface a peculiar effect, resembling the scales on some butterfly wings. This sculpture extends to the basal fasciole. The fasciole itself and the area immediately posterior to it, as well as the rest of the columella, are marked by spiral threads. The aperture is moderately long and broad and strongly channeled anteriorly.
|
|
The prosoma ("head") was trapezoid and somewhat narrow anteriorly, being close to that of Eurypterus. It was surrounded by a wide marginal border. The lateral eyes were small (about 1.5 millimetres or 0.06 inches long), reniform (bean-shaped) and close to the prosoma, resembling Nanahughmilleria. The ocelli (simple eye-like sensory organs) occupied a subcentral (almost central) position, immediately behind the eyes.
|
|
One variety has a pair of dark converging lines. The forewings have two conspicuous raised tufts of scales, one lying anteriorly, and a larger one posteriorly with a small tuft between the two. The hindwings are cream-coloured with long hairs posteriorly. The male can usually be distinguished from the female by the long hairs on the end of the abdomen.
|
|
There are seven white wedge-shaped marks from the costa on the posterior half, anteriorly somewhat oblique, posteriorly direct, one from the tornus and a dot on the termen beneath the apex, the space between these with violet and bronzy reflections. There is also a round deep black spot at the apex. The hindwings are light grey, with bronzy and purple reflections.
|
|
The dorsal surface is mottled brownish-grey with darker speckling. The patagium (winglike membrane) is dark brown near the edge and paler brown near the body, with six transverse pale-edged bands. The ventral surface is yellow or pinkish, with the gular pouch a creamy yellow anteriorly, and bluish-grey and black posteriorly. The underside of the patagium is yellowish-brown.
|
|
After the fusion of the main nerve trunks of the nonclamp side, some prominent nerves arise to innervate the lappet. The innervation is different from that of Gastrocotyle trachuri. This is probably due to the attitude of clamps formation of P. trachuri, that occur in a posteroanterior direction, thus, the “prehaptoral” ganglion moves more anteriorly, close to the anteriormost clamps.
|
|
The forewings are ochreous brownish, more ochreous towards the costa anteriorly. The costal edge is blackish towards the base. The stigmata is moderate, dark fuscous, with the discal approximated, the plical spot is obliquely before the first discal. The posterior portion of the wing is slightly infuscated with an indistinct curved transverse shade of ground colour at about four-fifths.

Species of Gattyana are short-bodied scale worms with about 34 to 40 segments and 15 pairs of elytra which cover the dorsum completely and have a marginal fringe of papillae. The prostomium is bilobed anteriorly and a pair of cephalic peaks is present. The lateral antennae are inserted ventrally directly beneath the median antenna. The neuropodial lobe is elongate and tapering.
|
|
Through directional migration - which requires multiple genes to work, one being the Columbus (clb) gene, which codes for Drosophila HMG CoA reductase - the germ cells move towards the somatic gonadal precursor cells and associate with them. These two associated cell types then migrate together anteriorly, until they coalesce into the embryonic gonad at the future site of the mature gonad.
|
|
The forewings pale brownish-ochreous, irrorated with white on the veins, and with scattered dark fuscous scales. The base of the costa is suffused with dark fuscous and there are some blackish scales on the submedian fold before the first line. This line is whitish, posteriorly margined with dark fuscous. The second line is also whitish and anteriorly dark-margined.
|
|
The dorsal surface of the first body segment (pronotum) has a darker brown, patchy colouration at the apex. The crown of the pronotum has a longer, denser fringe of setae than anywhere else on the body. The setae on the pronotum can be clustered or not. The pronotum is transverse and arcuates anteriorly so that it projects over the head.
|
|
The length of the shell varies between 7 mm and 12 mm. (Original description) The small shell is elongate and ovate, compressed. it has about six whorls and a rather large smooth protoconch. The transverse sculpture of, on the body whorl, consists of about twenty- six broad flattened waves, strongly flexed, most elevated over the fasciole, and becoming narrower and less prominent anteriorly.
|
|
The spiral costulae are close together, round, larger on the ventral part of the body whorl, smaller anteriorly. Two small cords (the posterior one is filamentous) run over the anterior part of the sutural border. The outer lip is frail, wrinkled, arched. The columella is smooth, excavated posteriorly, almost straight at the origin of the siphonal canal, which is short and wide.
|
|
C. tarzan is approximately in total length, in snout-vent length (SVL), with anteriorly fused rostral crests to form a "spade-like" snout that projects 1 millimeter beyond its snout tip. The chameleon has green to light yellow coloration and has a dark transversal band when it is stressed. This species has a very low casque in comparison to other chameleons.
|
|
The thoracic inlet is essentially a hole surrounded by a bony ring, through which several vital structures pass. The thoracic inlet is bounded by: the first thoracic vertebra (T1) posteriorly; the first pair of ribs laterally, forming lateral C-shaped curves posterior to anterior; and the costal cartilage of the first rib and the superior border of the manubrium anteriorly.
|
|
The bone forms an ancestral component of the dermal roof and is typically thin compared to other skull bones. The squamosal bone lies ventral to the temporal series and otic notch, and is bordered anteriorly by the postorbital. Posteriorly, the squamosal articulates with the quadrate and pterygoid bones. The squamosal is bordered anteroventrally by the jugal and ventrally by the quadratojugal.
|
|
The forewings are dark fuscous with a large ochreous-yellow triangular blotch, edged anteriorly with ochreous whitish, extending on the costa from two-fifths to four-fifths, its apex touching the dorsum beyond the middle. The second discal stigma is blackish, resting on the posterior edge of this blotch. There is a terminal series of ochreous-whitish dots. The hindwings are grey.

In: K. G. Ross & R. W. Matthews (eds.), The Social Biology of Wasps. Ch 6, pp. 191–231. Cornell University Press, Ithaca, New York In Apoica pallens, queens and workers are usually about the same total size, but queens tend to be smaller than workers anteriorly and significantly larger posteriorly. This differentiation is thought to be the result of differences in ovary development.

Ancillista lineata Kiener, 1844 is cream, the spire callus on the apex is sometimes yellow. Central area of the body whorl with faint light brown zigzag axial lines and a spiral row of brown blotches anteriorly. Ancilista fusiformis Petterd, 1886 is slender, with light cream-brown coloring on the body with a white stripe at the suture. Ancillista ngampitchae sp. nov.

The prosoma (head) was large, with a subquadrate (almost square) to semielliptic (nearly elliptic), horseshoe-like outline. It was anteriorly surrounded by a broad and flat marginal rim that reached its posterior corners. The carapace (the exoskeleton part covering the prosoma) was rounded in the front. Its surface was somewhat inflated, being distinguished several narrow grooves and ridges, most of them wrinkle-like.
|
|
While this could happen in a single specimen, it is impossible to be in so many. Kjellesvig-Waering realized this and erected the species N. clarkei in 1964, named after Clarke, who described the original Shawangunk eurypterid fauna. This small species of only 4 cm (1.6 in) had a lanceolate carapace with intramarginal eyes located anteriorly. The telson was broad and lanceolate.
|
|
Males have a dark dusky brown upperside smeared with purple on the exterior margin of the fore-wing and hind-wing with a broad band to the exterior margin, whitish anteriorly, bluish posteriorly, with a central longitudinal row of small, dusky spots. The underside is light brown, with greyish exterior margins, discoidal marks and a submarginal row of indistinct blackish spots.
|
|
The exact phylogenetic position of Kiareopterus is uncertain. It was originally classified as a stylonurid by Waterston (1979). Later studies revealed important similarities with Brachyopterus, including the large eyes converging anteriorly, the lack of a cuticular ornament and simple rectangular appendage podomeres with pronounced ridges. These similarities prompted it to be classified as a close relative of Brachyopterus, within the family Rhenopteridae.
|
|
It is 11.5 mm (0.45 in) long and 11.9 mm (0.47 in) wide. The walking legs are only known by two joints which have large, curved spines, one on each side. These walking legs are characteristic of most carcinosomatids in which the legs were flattened and with the venter (abdomen) turned anteriorly. They were different from the highly differentiated legs of Megalograptus.
|
|
The moth flies from June to September depending on the location. Larva dirty lead grey, bearing a yellow dorsal stripe with dark edges and three raised black transverse spots anteriorly, posteriorly and in the centre, and black markings laterally. The larvae feed on lichen and algae, especially on Pinophyta, but also on oak and Calluna. Until June, on lichens on trees.
|
|
Xiphasia matsubarai has an elongated body that resembles an eel, and has a dorsal fin that covers the whole length of the body. They have gray-brown stripes that cover the length of their bodies starting at the head. The head is small and it is rounded anteriorly. The eyes are slightly smaller and located near the lateral sides of the head.
|
|
The shell is sculptured with about 5 lirulae, anteriorly granulose. The umbilicus is large, closely ornamented with about 3 spiral distant lines, and radiating costulations continued from the base. The umbilicus is bounded by a granular keel, but has three other distant spiral lines crossing the lirulae. The rounded aperture is indentated by the carinae, scarcely in contact parietally, iridescent inside and nacreous.
|
|
The height of the shell varies between 8 mm and 13 mm. The conic shell is well elevated. Its color is pale yellowish or reddish-brown, with broad dark brown oblique flammules. It is anteriorly somewhat articu-ated with red and yellowish-white in fine concentric lines with many elevated granulous spiral lines, of which three larger are next above the suture.
|
|
The junctions of the axial ribs with the spiral cords form slender tubercles, while the spaces enclosed between them appear as well rounded, strongly impressed pits. On the anterior half of the base, the axial riblets become much enfeebled, so that here the pitting is less apparent. The sutures are strongly constricted. The aperture is moderately large, decidedly channeled posteriorly and anteriorly.
|
|
Like other sloth lemurs and indriids, Mesopropithecus had rapid tooth development. Despite the similarities, there are several features that distinguish Mesopropithecus skulls from those of living indriids. The skull, including the zygomatic arch, is more robustly built. The temporal lines join together anteriorly into a sagittal crest and there is a distinct nuchal ridge that joins the rear of the zygomatic arch.
|
|
Species of Arthurdendyus are characterized by a bell-shaped pharynx and ovaries placed laterally to the male copulatory apparatus, while most land planarians species have ovaries located much more anteriorly, usually close to the brain or to the pharynx. Other characteristic shared with closely related genera, such as Artioposthia and Newzealandia, is the presence of adenodactyls in the copulatory apparatus.
|
|
PVD may also occur in cases of cataract surgery, within weeks or months of the surgery. The vitreous membrane is more firmly attached to the retina anteriorly, at a structure called the vitreous base. The membrane does not normally detach from the vitreous base, although it can be detached with extreme trauma. However, the vitreous base may have an irregular posterior edge.
|
|
The periphery of the body whorl is rounded. The base of the shell is inflated, well rounded, and somewhat attenuated anteriorly. The surface is covered by numerous equal and equally closely spaced slender wavy spiral striations, of which there are about forty between the summit and the periphery of the body whorl. The base is marked like the space posterior to it.

The skull of Zambiasaurus submersus was reconstructed by using eighteen different juvenile fossil fragments and fragments of an adult Zambiasaurus. The immature skull had the dimensions of long and wide while the adults had a skull long and wide. There are no teeth in both upper and lower jaws making it a herbivorous species. Skull tapers anteriorly, widest across occiput.
|
|
Males of T. spiralis measure between 1.4 and 1.6 mm long, and are more flat anteriorly than posteriorly. The anus can be found in the terminal end, and they have a large copulatory pseudobursa on each side. The females of T. spiralis are about twice the size of the males, and have an anus found terminally. The vulva is located near the esophagus.
|
|
At the apical fourth is an oblique narrow white streak directed outward and nearly meeting a similar but curved dorsal streak directed upward and outward. Both streaks are slightly edged with black anteriorly. The area between the dorsal streak and the edge of the wing is white, mottled finely with black, each scale being tipped with black. The hindwings are dark purplish fuscous.
|
|
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.
|
|
The forewings are pale brownish ochreous, more or less suffusedly irrorated (sprinkled) with dark grey, and the apical three-fifths irregularly suffused with dark brown. There are spots of blackish irroration in the disc beyond the middle and at two-fifths, as well as a small blackish apical spot, edged anteriorly with whitish suffusion. The hindwings are dark grey.Meyrick, Edward (1916–1923).
|
|
The scleral spur is an annular structure composed of collagen in the human eye, a protrusion of the sclera into the anterior chamber. It is the origin of the longitudinal and circular fibres (which swerve acutely from the spur to run circumferentially as a sphincter near the periphery of the lens) of the ciliary muscle and is attached anteriorly to the trabecular meshwork.
|
|
The forewings are brownish orange, speckled with dark brown scales throughout and with a large, pale orange semi-ovate area well presented pre-apically, bordered by greyish-brown scales anteriorly, with two or three dark brown spots on the inner side. The termen is slightly oblique, with the fringes dark brown, relatively short on the termen, longer on the inner margin.

No canal or groove in floor of basioccipital or basisphenoid for basilar artery. Suprastapedial process of quadrate distally expanded. Dorsal edge of surangular thin lamina of bone rising anteriorly to posterior surface of coronoid...At least 31, usually 42–45 presacral vertebrae present. Length of presacral series exceeds that of postsacral, neural spines of posterior caudal vertebrae elongated to form distinct fin.
|
|
There is a triangular blackish blotch occupying the median third of the costa, and reaching two-thirds of the way across the wing. The hindwings are fuscous, thinly scaled and subhyaline (almost glass like) anteriorly, with strong violet-blue iridescence and with the veins, apical area, and termen suffused with dark fuscous.Journal of the Bombay Natural History Society. 22 (1): 162.
|
|
Each abdomen segment of the abdomen has paired patches of tiny spines which show through the scales. The resting position is horizontal with the front end raised and the cilia give the hind tip a frayed and upturned look if the wings are rolled around the body. C. adjunctella characteristics include:- Head brownish. Antennae dark fuscous, faintly ringed anteriorly with whitish.
|
|
Hindwing: a basal short, brownish-black, anteriorly attenuate bar placed obliquely, a transverse subbasal band of four large coalescent black spots, a transverse curved discal band twice broken as on the forewing and similar postdiscal subterminal and terminal markings. Antennae black, shafts ringed with white, head, thorax and abdomen dark brownish black; beneath: the palpi black, thorax and abdomen down the middle white.
|
|
The forewings are dark purple-fuscous with a direct transverse whitish-ochreous streak just before the middle, slightly angulated inwards towards the costa. There is a fine series of scattered whitish-ochreous scales from a dot on the costa at four-fifths to the dorsum before the tornus, angulated outwards in the middle. The hindwings are dark grey, lighter in the disc anteriorly.

|
Cephalotropis is diagnosed by the following features: a long sagittal crest, a more anteriorly produced angle of the supraoccipital angle, among other features.Case, E. C., 1904. Systematic Paleontology, Miocene, Mammalia, in Clark, W. B., Shattuck, G. B., and Dall, W. H., The Miocene There is insufficient information to determine how big Cephalotropis was, but it probably grew to about 16–20 feet long.
|
|
The upper border of the ramus of mandible is thin, and is surmounted by two processes, the coronoid process anteriorly and the condyloid process posteriorly, separated by a deep concavity, the mandibular notch, or sigmoid notch. It allows the passage of the masseteric nerve (a branch of the mandibular nerve (V3) division of the trigeminal nerve), masseteric artery and masseteric vein.
|
|
In order to be classified as BSS, the anterior flexion (the lower back bending) must be of 45 degrees anteriorly. This classification differentiates it from a similar syndrome known as kyphosis. Although camptocormia is a symptom of many diseases, there are two common origins: neurological and muscular. Camptocormia is treated by alleviating the underlying condition causing it through therapeutic measures or lifestyle changes.

Otolaryngol Head Neck Surg. 2001 Jan. 124(1):68-71. [Medline]. This modified procedure involves a judicious excision of 3.5–4 mm C-shaped wedge in posterior vocal cord from the open edge of the membranous cord using carbon dioxide laser. Excision is made anteriorly to the vocal process, continuing 4 mm laterally on to the ventricular band without exposing the cartilage.
|
|
While any (or all) of the three branches may present themselves, their constancy of location is what allows this to be defined as a distinct syndrome. One branch sets off anteriorly to the groin or pubic region. A second branch remains posterior, innervating the lower back and upper gluteal region. Thirdly a lateral take-off passed down the anterolateral thigh or trochanter region.
|
|
The talus then moves laterally, shearing off the lateral malleolus or, more commonly, breaking the fibula superior to the tibiofibular syndesmosis. If the tibia is carried anteriorly, the posterior margin of the distal end of the tibia is also sheared off by the talus. A fractured fibula in addition to detaching the medial malleolus will tear the tibiofibular syndesmosis.Moore and Agur.

Exiguodon is distinguished from other hyainailourines by the following features: diminutive dimensions, lower molars (m3 – m2) with greatly reduced talonid; protoconid and paraconid similar in size. Paraconid of the molars lingually oriented. M2 and M1 close in size and morphology. Occlusal outline sub-triangular, with greatly reduced protocone, which appears like an antero-lingual cingulum which extends anteriorly and buccally.
|
|
Upperside fuscous black. Forewings and hindwings: jet-black anteciliary slender lines and on the hindwing, traces of a subterminal line of black spots. Cilia, forewing: dusky brown; hindwing: white alternated with brown at the apices of the veins. Underside: white with a greyish tint on the forewing except on the posterior terminal third and on the hindwing on the basal area anteriorly.

|
The five whorls of the teleoconch are increasing rapidly in size, early ones well rounded, later ones less so, their summits being closely appressed to the preceding whorl. The simple sutures are well impressed. The periphery and the base of the body whorl are well rounded, the latter somewhat elongated. The aperture islarge, ovate, somewhat effuse anteriorly, milk-white within.

Alvarez' syndrome is a medical disorder in which the abdomen becomes bloated without any obvious reason, such as intestinal gas. It may be caused when the muscles of the superior abdominal wall contract and push the contents of the abdomen inferiorly and anteriorly. It may be a psychogenic disorder. It was discovered by and named for Walter C. Alvarez in the late 1940s.
|
|
The periphery of the body whorl is well rounded, marked by a low spiral cord. The base of the shell is strongly rounded posteriorly and attenuated anteriorly. It is marked by seven spiral cords, which grow successively weaker from the periphery toward the umbilical region and are separated by slender, deeply incised spiral lines. The aperture is large and broadly oval.
|
|
In addition to these spiral cords the whorls are marked by weak axial ribs which extend only feebly to the first supra-peripheral cord, rendering the junction with the cords feebly nodulous. The sutures are strongly constricted, not channeled. The periphery of the body whorl is marked by a spiral cord. The base of the shell is rounded, slightly channeled anteriorly.
|
|
The dorsal process of the stapes in Theriognathus is greatly reduced or entirely absent. The dentary is short, shaped like a banana, and continuously tapers anteriorly to a narrow edge. The dentarys’ lateral surface is smooth. The posterodorsal terminal end of the coronoid process is more rounded, and the dorsal extent terminates below the middle of the orbit in adults.
|
|
The forewings are ochreous fuscous with four, narrow, elongate ochreous-whitish costal spots, the first before the middle, the second beyond the middle, the third at three-fourths and the fourth midway between this and the apex. There is a blackish ante-apical dot in the disc, edged anteriorly with white. The hindwings are fuscous.Transactions of the Royal Society of South Australia.

Anteriorly, T. cincinnatus has several long feeding tentacles and two pairs of filiform branchia. The ventral lobes are thick and many eye spots can be seen. Notochaetae can be observed from the segment where the second branchia occurs, and uncini occur from the third segment. The worm itself is pink orange or brown with lighter colouration on the ventral side.
|
|
The forewings are white, slightly sprinkled with pale greyish ochreous except towards the costa anteriorly, the terminal edge is pale greyish ochreous. The stigmata are small and black and there is a strongly curved series of minute scattered black specks from beneath the costa at three-fourths to above the dorsum at two-thirds. The hindwings are grey whitish.Meyrick, Edward (1912–1916).

The growth lines are directed at right angles to the growth direction of the cone, but become flexuous or sinuous on the lower whorls. The base of the body whorl is well rounded. The sutures are well impressed. The narrowly oval aperture is rather large and occupies about ⅓ of the total length, and is somewhat effuse anteriorly The posterior angle is obtuse.
|
|
The forewings are ochreous, more or less sprinkled with fuscous except towards the costa anteriorly. The costal edge is black towards the base. The stigmata is black, the plical rather obliquely before the first discal. There is a moderate dark grey terminal fascia, sprinkled with black, the anterior edge slightly convex, suffused with black and preceded by a clear ochreous shade.
|
|
The shell is marked by seven rather broad spiral cords, which are separated by narrow channels. The aperture is short, decidedly channeled anteriorly and posteriorly, the posterior channel being deeply notched and at the summit of the shell. There is a broad varix half a whorl behind the aperture. The outer lip is protracted between the sinus and the basal portion.

|
The upper labials and the ventrum are yellowish. The ventrals are 178-183, and the subcaudals are 172-202. (Both these counts are higher than in C. carinatus.) The dorsal scales are arranged in 12 rows anteriorly and at midbody, in 10 rows posteriorly. (C. carinatus has 8 rows posteriorly.) Adults may attain a total length of , with a tail long.
|
|
The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint of the inguinal ligament, halfway between the anterior superior iliac spine and pubic tubercle, is the landmark for the femoral nerve.
|
|
The forewings are light ochreous, slightly brownish tinged. The discal stigmata are minute and rather dark fuscous. There is a curved subterminal series of small groups of rather dark fuscous scales becoming obsolete towards the margins. The hindwings are pale grey, tinged with ochreous whitish anteriorly and with an inwards-oblique mark of dark grey suffusion from the posterior edge of the concavity.
|
|
The dorsal fin spine is smooth, and the pectoral fin spine is smooth anteriorly and finely serrate posteriorly. The dorsal, pectoral, and caudal fin lobes sometimes with filamentous extensions. The head and body is entirely or almost entirely covered by heavily keratinized skin superficially differentiated into unculiferous plaques or tubercles. Bagarius species lack a thoracic adhesive apparatus and paired fins are unplaited.
|
|
The heavier incremental lines terminating anteriorly in the spiral line of pits divide the space between the spiral lines into scalelike elements suggesting the scales of some butterfly wings, each scale being bordered by a deeper axial depression and marked by microscopic axial striations, as well as the microscopic spiral lines, the axial striations being a little stronger. The columella has a moderately strong basal fasciole, which is bordered posteriorly by three feeble spiral threads and crossed by two more, whereas anterior to the basal fasciole the columella bears aboutsix feebly impressed spiral threads. The aperture is moderately large, rather broad, slightly channeled anteriorly with the posterior channel deeply incised and its wall reflected as a strong callus over the parietal wall. The stromboid notch at the anterior end of the outer lip is rather short and shallow.
|
|
The wingspan is about 13 mm. The forewings are leaden grey with a rather oblique violet-golden-metallic streak from the costa at one-third, edged with black on both sides, more broadly towards the costa anteriorly, almost meeting a similar erect streak from the dorsum in the middle, edged black anteriorly. Beyond these is a broad brownish-ochreous transverse band dilated towards the costa, limited posteriorly by an inwards-oblique pale yellowish black-edged mark from the costa at four-fifths and an erect violet-golden-metallic streak from the dorsum at four-fifths. A rather down-curved light blue-grey line connects the apices of the two dorsal streaks and from the apex of the yellowish mark, a violet-golden-metallic line runs to the apex of a rather oblique blue-grey fasciate streak from the middle of the costa.
|
|
The carapace is brown to gray or black. The plastron covers much of the carapacial opening, is slightly upturned anteriorly, and is posteriorly notched. The intergular scute completely separates the gulars, but not the humerals, and is slightly shorter than, or about the same length as, its distance from the abdominals. The plastral formula is variable, but the femoral, abdominal and intergular scutes are usually longest.
|
|
The surface is everywhere crossed by conspicuous, flexuous lines of growth. The protoconch is rather large, composed of 2½ regularly coiled, nearly smooth, somewhat shining whorls, the second having a row of minute nodules or beads on the periphery. The aperture lis ong, narrow, of nearly uniform width. The outer lip is thin, nearly straight, broadly rounded anteriorly, with a decided sinus just below the suture.
|
|
From October to July on Poa. Pupa anteriorly bone -yellow marked with dark, abdomen cinnamon with dark incisions; so covered among the roots of grass that only the head is visible (Gross-Steyer). The butterfly appears in August and September, fluttering with a jerky flight in meadows and on grassy slopes of the mountain and alpine regions. In some years not rare, occurring up to 6000 ft.
|
|
The suture is appressed behind a faint anal fasciole. The whorls are moderately rounded. The spiral sculpture is uniform, consisting of fine attenuated close-set spiral threads covering the whole surface and crossed by minutely sharp incremental lines giving a peculiarly rough effect. The other axial sculpture consists of (on the body whorl about 12) rather feeble rounded ribs obsolete anteriorly with about equal interspaces.
|
|
The subsequent whorls show about ten axial riblets, slightly flexuous near the suture and becoming obsolete anteriorly. The peripheral part of the body whorl is smooth or destitute of spiral sculpture, which on the base and the siphonal canal is well developed and consists of fine striation. The notch is short, subcircular, leaving no fasciole. The outer lip is slightly thickened, not lirate within.

|
Members of the genus Atractaspis share the following characters. Venom fangs enormously developed; a few teeth on the palatines, none on the pterygoids; mandibles edentulous anteriorly, with 2 or 3 very small teeth in the middle of the dentary bone. Postfrontal bone absent. Head small, not distinct from neck, covered with large symmetrical shields; nostril between 2 nasals; no loreal; eye minute, with round pupil.
|
|
The spotted blue-eye has an elongated body generally up to 2.5 cm (1 in), or rarely 3 cm (1.2 in) in length. The overall colour is transparent to pale silver-white, sometimes with tints of tan or yellow. The rear half of the body is marked with three horizontal black lines, breaking up into spots anteriorly. The fins are yellow with black markings.
|
|
The cuneus (Latin for "wedge"; plural, cunei) is a smaller lobe in the occipital lobe of the brain. The cuneus is bounded anteriorly by the parieto- occipital sulcus, inferiorly by the calcarine sulcus. The cuneus (Brodmann area 17) receives visual information from the same-sided superior quadrantic retina (corresponding to contralateral inferior visual field). It is most known for its involvement in basic visual processing.
|
|
Each whorl spreads in a broad shelf above, and thence narrows anteriorly. Sculpture:—On the body whorl there are four, and on the earlier two, spiral cords, the topmost running along the angle of the shell. The radials which over-ride these are thin elevated lamellae, commencing at the suture and ending as imbricating scales on the snout. There are sixteen on the body whorl.
|
|
In addition to the spiral sculpture the whorls are marked by axial ribs which have their beginning in the nodulose spiral threads on the first postnuclear whorl. These axial ribs are slightly protractively slanting. They extend but very slightly posteriorly to the posterior sulcus, and evanesce anteriorly on the base of the body whorl. They are more than twice the width of the spaces that separate them.

Caponiidae is a family of ecribellate haplogyne spiders that are unusual in a number of ways. They differ from other spiders in lacking book lungs and having the posterior median spinnerets anteriorly displaced to form a transverse row with the anterior lateral spinnerets. Most species have only two eyes, which is also unusual among spiders. A few species of Caponiidae variously have four, six or eight eyes.

The creek whaler (Carcharhinus fitzroyensis) is a common species of requiem shark, and part of the family Carcharhinidae, endemic to northern Australia. It frequents shallow waters close to shore, including estuaries. This small, stocky shark usually grows to long and is brownish in color without conspicuous fin markings. It can be identified by its long snout, large, triangular pectoral fins, and large, anteriorly positioned first dorsal fin.
|
|
The columellar wall is reflected as a heavy callus. The parietal wall shows a heavy callus that forms a knob at the exterior angle. The sculpture consists of strong axial ribs that extend from the anterior limit of the concave area, where they are strongest over the base, growing feebler anteriorly. Fine incremental lines are also present on the ribs and in the intercostal spaces.
|
|
The pelvic outlet is the margin of the true pelvis. It is bounded anteriorly by the pubic arch, laterally by the ischia, and posteriorly by the sacrum and coccyx. The superior pubic ramus is a part of the pubic bone which forms a portion of the obturator foramen. It extends from the body to the median plane where it articulates with its fellow of the opposite side.

The right humerus is very fragmented, only preserving the proximal end and although the distal expansion is missing, it has a notable reduced distal end. Anteriorly, it preserves a developed depression for muscular attachment. The preserved right femur is more gracile compared to other elements, indicating that the animal had stronger forelimbs. This is seen as a possible and potential autapomorphy for this species.
|
|
The thorax and tegula are ochreous brown tinged with yellow. The forewing is broad, nearly rectangular and the apex is slightly protruding anteriorly. The ground color is yellow, with scattered pale ochreous scales medially, densely covered with ochreous brown scales along the dorsal area. The markings are ochreous brown with sparse brownish black scales: the costal margin with two dots near the base and a triangular spot.

One of the earliest fossil brain endocast studies has been performed for Triconodon. The olfactory lobe is large, with a teardrop-shaped outline, suggesting a well developed sense of smell. The cerebral hemisphere is long, oval and flat, lacking the inflated appearance present in monotremes, multituberculates and therians. The cerebrum is neither expanded anteriorly to overlap the posterior part of the olfactory lobe, nor is it hemispherical.
|
|
The first upper labial is not fused to the nasal and is completely separated by a suture. The supraoculars are large, 5-9 scales in a line between them. The internasals are usually not in contact with one another, separated by 2 small suprapostrostral scales. There are 7-10 upper labials, the second of which is usually fused to the scale bordering the facial sensory pit anteriorly.

BAMONA In Seitz iit is described thus - E. discoidalis Krb. (= lena Christ.) (37 h). The forewing narrow, with the apex rounded, the costal margin being brownish grey and striated with whitish grey and brown. The dull brown disc broadly bordered with dark chocolate anteriorly and posteriorly, this border being narrow on the distal side, the dark apex of the wing feebly dusted with grey.
|
|
The forewings are ochreous brown, with scattered dark fuscous scales and a blackish streak irregularly interrupted and spotted with ground colour extending along the costa from the base to three-fourths. The stigmata are undefined, fuscous, with the discal approximated, the plical rather before the first discal. A streak of blackish irroration (sprinkles) runs along the termen, suffused with grey anteriorly. The hindwings are iridescent grey.
|
|
The wingspan is about . The forewings are greyish ochreous, strigulated with ferruginous brown and with a small blackish spot on the base of the costa and a dot beneath the costa near the base. The costal edge is pale rosy anteriorly, strigulated with blackish. There is a triangular blackish spot on the costa before the middle, reaching one-third of the way across the wing.
|
|
Other distinguishing features include 67 to 70 lateral line scales and a total of 34 vertebrae. The species has a known maximum length of 20 cm. The swim bladder has two anterior extensions which extend forward and diverge before terminating above the auditory capsule. Two lateral extensions commence anteriorly, sending tubules to the anterior and extending below the abdominal wall adjacent to the swimbladder.
|
|
Male upperside: shining purplish black. Forewing: costa narrowly and evenly for three-fourths of its length from base, apex broadly and terminal margin decreasingly jet black; cilia black. Hindwing: costa and apex broadly, termen narrowly, bordered with black; a subterminal series of small round black spots that merge anteriorly into the black at apex j cilia black, tipped with white. Underside: opaque chalk white.

|
This species of Neptosternus is easily recognized by its dark appearance, and by the shape and position of its elytral yellow spots. It differs from Neptosternus starmuehlneri (Wewalka, 1973) in being longer and comparatively narrower, and in having the yellow markings less developed. Its length is between , while its breadth is . It has an elongate, oval shape, more attenuated posteriorly than anteriorly and not strongly convex dorsally.
|
|
The forewings are white, becoming pale greyish ochreous posteriorly, with a few fine scattered black scales, towards the apex and termen sprinkled with grey. The posterior half of the costa has short oblique alternate strigulae of grey suffusion and white and there is a fine white terminal line edged anteriorly by a row of black dots preceded by fuscous suffusion. The hindwdngs are whitish.Meyrick, E. (1910).
|
|
The distribution of the degeneration is crescent or arcuate shaped. The cornea just above the region of thinning is of normal thickness, and may protrude anteriorly, which creates an irregular astigmatism. This is described as a "beer belly" appearance since the greatest protrusion occurs below the horizontal midline (unlike keratoconus). Normally, PMD does not present with vascularization of the cornea, scarring, or any deposits of lipid.
|
|
Alpheus fasqueli has a carapace length of about , a total length of and chela length of . Its carapace is smooth, possessing shallow grooves latero-anteriorly, and scattered setae dorsally. Its pterygostomial angle is rounded, while its rostrum is well developed and descendant; its orbital hoods are inflated, lacking teeth. Its corneas are well developed, while its eyes have small anterior processes, and its antennular peduncles are stout.
|
|
Its anterior nares are large, almost equal to the diameter of its eyes. The ethmoid region between its anterior nares is broad, with a rounded anterior margin. Its eye position is lateral, and its premaxilla contains 13–15 teeth which are disposed in a single row along the outer margin. These teeth are shaped roughly as an arrow-head anteriorly, while being conical posteriorly.
|
|
Restoration of S. spinipes. Stylonurella was a small stylonuroid, possessing a subquadrate prosoma with approximately the same length as width. The midsection was slightly constricted and the eyes were parallel and anteriorly located in the anterior half of the carapace. The metastoma and first two appendages are unknown, the third and fourth prosomal legs are very short and the last two walking legs are very long.
|
|
The zonules of Zinn are difficult to visualize using a slit lamp, but may be seen with exceptional dilation of the pupil, or if a coloboma of the iris or a subluxation of the lens is present. The number of zonules present in a person appears to decrease with age. The zonules insert around the outer margin of the lens (equator), both anteriorly and posteriorly.
|
|
The third lamella supports the third vane, which is located more distally and lies perpendicular to the other two vanes or lamellae. All three lamella have striations when viewed in a longitudinal section and these striations are perpendicular to the ‘9+2’ axoneme. Carpediemonas contains a single ovate nucleus, located anteriorly in the cell. The nucleolus can also be found subcentrally within the nucleus.
|
|
E. stygne O. (= pirene Hbn).) (35 g). Upperside of both wings dark black-brown. The forewing has before the distal margin a russet-brown band which is broad anteriorly, strongly tapering behind, and bears in its upper portion 2 white-centred black ocelli; towards the hindmargin an additional, somewhat smaller ocellus is visible. The hindwing has 3—4 white-centred ocelli which are edged with brown.
|
|
Other distinguishing features include 67 to 72 lateral line scales and a total of 33 to 35 vertebrae. The species has a known maximum length of over 16 cm. The swim bladder is similar to the Japanese whiting, characterised by a short central anterior extension with two anteriorly facing anterolateral projections, which may be well or poorly developed. There is a single median posterior extension.
|
|
The veins are faintly yellowish-tinged, near apex more fuscous ; costal edge anteriorly finely dark fuscous, near apex more strongly; costal cilia fuscous or dark fuscous except at base and tips. Hindwings rather dark grey.Meyrick, E., 1895 A Handbook of British Lepidoptera MacMillan, London pdf Keys and description Only reliably identified by dissection and microscopic examination of the genitalia. Adults are on wing from June to July.
|
|
The origins of anal and pelvic fins are displaced anteriorly, while the origin of pectoral fins is displaced posteriorly. Pelvic and pectoral fins and last anal-fin ray are longer in the new species. Unlike the other phylogenetically related species, the Lisbon's arched-mouth nase shows external sexual dimorphism, with males having longer pelvic fins whose extremities pass the anus and often overlap with the anal fin.
|
|
The forewings are ochreous-whitish, suffused with pale ochreous- yellowish in the disc and sprinkled with dark fuscous. The first line is ochreous-white, edged posteriorly with dark fuscous suffusion. The second line is ochreous-white, edged anteriorly with dark fuscous. The terminal area is irrorated with dark fuscous and there is an ochreous-whitish subterminal line, as well as an interrupted ochreous-white terminal line.
|
|
Adult males measure and adult females in snout–vent length. The tympanum is well-defined and pale anteriorly. An oblique lateral pale line extends halfway from groin to the eye- Adult males with solid black throat, with the black pigmentation usually extending onto the chest and the anterior belly; adult females have white (unpigmented) or faintly pigmented gray or brown chest. The toes are moderately webbed.
|
|
In certain model systems, it has been shown that the daughter cells of stem cell-like progenitor cells which come from the primitive streak or site of gastrulation migrate out and localize in the posterior paraxial mesoderm. As the primitive streak regresses and somites bud off anteriorly, new cells derived from these stem-cell like precursors constantly enter the posterior end of the paraxial mesoderm.
|
|
The semilunar hiatus or hiatus semilunaris, is a crescent-shaped groove in the lateral wall of the nasal cavity just inferior to the ethmoid bulla. It is the location of the openings for maxillary sinus. It is bounded inferiorly and anteriorly by the sharp concave margin of the uncinate process of the ethmoid bone, superiorly by the ethmoid bulla, and posteriorly by the middle nasal concha.
|
|
Females and juveniles are black and have three light cream stripes, which are yellow on the head, running down the lizard's back. The middle stripe is narrow and broken near the rear, and the tail is straw-colored. The throat is white, while the belly is mainly black. Adult males have a yellow head and a dark red body with several large, whitish spots anteriorly.
|
|
Gases are exchanged in the numerous filaments, and oxygen absorption is especially facilitated by hemocyanin. Red king crabs exhibit unidirectional ventilation. This can be described as the flow of water in a U-shaped course; water passes posteriorly from the incurrent opening, an opening in the carapace near the base of the chelipeds, dorsally over the gills, and anteriorly to exit beside the head.
|
|
The sutures are strongly constricted. The periphery of the body whorl is marked by a spiral groove, crossed by the continuations of the axial ribs, which terminate at the posterior edge of the first basal keel. The base of the shell is well rounded posteriorly, somewhat attenuated anteriorly. It is marked by six almost equal spiral keels, which are less developed about the umbilical area.
|
|
Oxymonas is found to be sub- elliptical in its body shape and has a pointed posterior end. Oxymonas is distinguishable by the rostellum, which can be thought of as a elongated proboscis. The rostellum projects anteriorly from the organism and ends in a holdfast apparatus that allows for the attachment to the gut of the termite. The rostellum is composed of a system of microtubules.
|
|
Cochlosoma species have asymmetrical ovoidal shaped bodies (6-18 µm) that are broader anteriorly and narrower posteriorly. Their anterior end is truncated by a spiraled adhesive disc that is used to attach to the intestinal mucosa of the host. A lateral groove develops along the side of the body from the disc. Six flagella of varying lengths arise from the anterior end of the cell.
|
|
Primary cysts come in various sizes and number but are usually fluid- filled, with regular borders and a smooth surface. The iris could be slightly displaced anteriorly because of a primary cyst, but normally no problems occur with primary cysts. Secondary cysts cause most of the times problems, and thus also need treatment. Secondary cysts usually have a rough surface, irregular borders, solitary and unilateral.
|
|
The lateral line is strongly curved anteriorly, with a section of 6 to 11 scutes toward the tail. Juveniles and often adults have long, filamentous trailing first anal and dorsal fin spines, a trait of all members of Alectis. The species grows to at least 1 m in length. The African threadfish is silver in colour, often with blue and greenish tints and reflection, especially when fresh.
|
|
This occlusal scheme was first described by Dr. M. M. DeVan in 1951. Monoplane occlusion involves having non-anatomic denture teeth with a 0˚ incisal guidance angle, arranged on a flat occlusal plane. As a consequence, when patients with monoplane occlusion occlude anteriorly, an interocclusal gap appears posteriorly. This is termed the 'Christensen phenomenon' and forms the basis for categorising monoplane occlusion as non- balanced.
|
|
The pelvic skeleton is formed posteriorly (in the area of the back), by the sacrum and the coccyx and laterally and anteriorly (forward and to the sides), by a pair of hip bones. Each hip bone consists of 3 sections, ilium, ischium, and pubis. During childhood, these sections are separate bones, joined by the triradiate cartilage. During puberty, they fuse together to form a single bone.
|
|
Coronal section through pubic symphysis The two hip bones are joined anteriorly at the pubic symphysis by a fibrous cartilage covered by a hyaline cartilage, the interpubic disk, within which a non-synovial cavity might be present. Two ligaments, the superior and inferior pubic ligaments, reinforce the symphysis.Platzer (2004), p. 188 Both sacroiliac joints, formed between the auricular surfaces of the sacrum and the two hip bones.
|
|
The anterior interosseous nerve is a branch of the median nerve, with a large sensory branch to the wrist bones, which arises just below the elbow. It passes distally, anteriorly along the interosseous membrane and innervates flexor pollicis longus, flexor digitorum profundus to index and middle finger as well as pronator quadratus, and supplies sensory feedback from the wrist bones, ie the carpal tunnel, not skin.
|
|
Yukoniidae are typically isopygous, belonging to the Superfamily Eodiscoidea. The narrow glabella is usually parallel sided, anteriorly rounded and separated from smooth anterior border by broad (sag.) preglabellar field which occupies about 25% of cephalic length excluding occipital spine. Posterior glabellar furrows are reduced to a pair of slits low on sides of glabella and directed backwards. Occipital ring bears a strong backwardly directed spine.
|
|
The forewings are pale brownish ochreous, irregularly irrorated (sprinkled) with and partially suffused with dark fuscous, especially towards the dorsum and posteriorly. There is a spot of whitish-ochreous suffusion beneath the costa near the base. The stigmata are dark fuscous, very obscure, the plical beneath the first discal, the second discal more distinct, partially surrounded with whitish-ochreous suffusion. The hindwings are fuscous, paler anteriorly.
|
|
While the houndfish has no spines, its dorsal fin has 21–25 soft rays, and its anal fin has 19–22. They are also known to have 80–86 vertebrae. A key way of distinguishing the houndfish from other members of the genus Tylosurus is that the houndfish's teeth point anteriorly when the fish is a juvenile. The teeth of other species are straight at all ages.
|
|
The vocal folds are located within the larynx at the top of the trachea. They are attached posteriorly to the arytenoid cartilages, and anteriorly to the thyroid cartilage. They are part of the glottis which includes the rima glottidis. Their outer edges are attached to muscle in the larynx while their inner edges, or margins, are free forming the opening called the rima glottidis.
|
|
Internally, the head is divided into four glandular cervical sacs that attach near the esophagus, as well as four hollow spaces called ballonets, each being continuous with a cervical sac via a central canal.Barnes, R. 1987. Invertebrate Zoology. Orlando, Florida: Dryden Press The body is typically pink and is also covered anteriorly with circles of flat spines, which become sparser and single-tipped further toward the end.
|
|
The stroma of the cornea (or substantia propria) is a fibrous, tough, unyielding, perfectly transparent and the thickest layer of the cornea of the eye. It is between Bowman's membrane anteriorly, and Descemet's membrane posteriorly. At its centre, human corneal stroma is composed of about 200 flattened lamellæ (layers of collagen fibrils), superimposed one on another. They are each about 1.5-2.5 μm in thickness.
|
|
Arivaca poohella is a species of snout moth described by Jay C. Shaffer in 1968. It is found in the US from southern Arizona through New Mexico to Texas. There is a white costal band on the forewing, extending halfway from the cell to the costa, it is bordered anteriorly with light orange. The hindwings are dark brown in males and light brown in females.
|
|
The primary contributing factor to labial fusion is low estrogen levels. A vulva with low estrogen exposure, such as that of a preadolescent, has delicate epithelial lining and is therefore vulnerable to irritation. Conditions causing irritation, such as infection, inflammation and trauma, cause the edges of the labia minora to fuse together. The fusion typically begins at the posterior frenulum of the labia minora and continues anteriorly.
|
|
The forewings are shining snow white with the extreme costal edge ochreous, becoming indistinct at around the apex and fuscous at the base. There is a broad light fuscous longitudinal streak along the inner margin, from near the base to the anal angle, and continued right through the cilia, somewhat attenuated anteriorly. The hindwings are pale grey. The larvae feed on Grevillea species, including Grevillea mimosoides.
|
|
The ocelli show through distinctly above and are yellow in the middle with white crescents and sharply ringed with black. On the forewing four or five, on the hindwing always four eyespots, the apical one sometimes doubled, being accompanied anteriorly by a halved eyespot. The species flies rather high; Garlepp met with it at Cocapata in Bolivia at elevations of about 2600 m.Fruhstorfer, H., 1913.
|
|
The second and third vertebrals are broader than long in the young, nearly as long as broad in the adult, narrower than the costals. The plastron is large, angulate laterally, truncate anteriorly. The posterior lobe of the plastron is much narrower than the opening of the shell, nearly as long as the width of the bridge, deeply notched posteriorly. The head is rather large.
|
|
The arched, elliptical carapace (to 23 cm) is widest behind the middle and unserrated posteriorly. The medial keel is prominent with a strong spinelike posterior projection on the 3rd vertebral. Vertebrals 2 and 5 are broader than long, while 1, 3, and 4 are longer than broad. Vertebral 3 is posteriorly pointed while the 4th is anteriorly pointed, making the seam between these two scutes very short.

Franklin's bumblebee is distinguished from other bumblebees by a solid black abdomen, with yellow anteriorly on the thorax in a U-shaped design.Franklin's bumble bee may be extinct. Phys.org. 26 May 2009. Females have black hair on their faces and the vertices, with some light hairs mixed above and below their antennal bases, while most similar bumblebee species have yellow.Bumble bees: Franklin’s bumble bee (Bombus franklini).

In contrast to the jaw, Pachyophis teeth clearly resemble that of snakes. Their dentition show thecodont nature, their teeth fitted into bowl like alveoli lined on the jaw bones. The enamel layer of the teeth is well developed with large, hollow pulp cavities possessing small openings leading into them. The tooth row extends the entirety of the jaw with the teeth curving backwards anteriorly.
|
|
The base of the forewings is black, the costa is marked with cinereous (ash gray) to the middle. The ground color is light brownish fuscous, darker basally and faintly irrorated (sprinkled) with cinereous. There is a strongly marked, longitudinal black dash in the cell, edged anteriorly with cinereous. There is a series of indistinct, blackish spots around the termen at the ends of the veins.
|
|
Preaxial polydactyly occurs in SSTM 5025, where extra digits only develop anteriorly to digit I. This condition is seen in earlier stem tetrapods from the Devonian period, such as Ichthyostega and Acanthostega. SSTM 5025 possessed seven digits on the forelimbs and six on the hindlimbs. The wide manus and pes of the specimen resemble the limb-like fins of extant frogfishes.Clack, J. A. (2002).
|
|
The aperture is quadrate and very oblique, the basal portion smooth inside. The columella is pearly, anteriorly terminating in a solid tubercle, and ascending with a semicircular sweep. The thin operculum is horny, multispiral with a central nucleus. Tectus royanus is allied to Tectus pyramis (Born, 1778), an Indo-Pacific species, but differs in colour and in sculpture, which is much finer than that in T. pyramisW.
|
|
These are wide anteriorly, and narrow to become acutely angled posteriorly. The of Europasaurus stands vertically, a basal feature not seen in Brachiosaurus or more derived sauropods. A series of all complete is only known from a single specimen, DFMMh/FV 100, which was destroyed in a fire in 2003. All five vertebrae, the characteristic number of more basal neosauropods, are incorporated into the .
|
|
The periphery and the base of the body whorl well rounded, the latter somewhat inflated and marked by six spiral cords, which are successively closer spaced and a little less strongly developed from the periphery to the umbilical area. The channels between the cords are crossed by many very slender raised vertical threads. The aperture is oval, slightly effuse anteriorly. The outer lip is thin.
|
|
The forewings are light brownish ochreous slightly speckled with fuscous, paler towards the costa and with the costal edged whitish tinged except towards the apex. The stigmata are cloudy, dark fuscous, the plical beneath the first discal, these edged posteriorly and the second discal anteriorly by a few whitish scales. There is a terminal series of minute indistinct dark fuscous dots. The hindwings are grey.
|
|
The suture is simple, narrowly margined. The body whorl is roundly contracted at the base. The aperture is elongate-oval, opening widely into a short siphonal canal. The outer lip is simple, thin, crenulated outside; with a deep rounded posterior sinus near the suture, having a thickened and slightly erect edge, with a shallow excavation anteriorly where it is pinched to form the canal.
|
|
Shell obliquely conical, thin, semitransparent, horn- colour, covered by a blackish coating. Apex inclined to the right, situated at the posterior third of the length; convex anteriorly, slightly concave on the posterior slope; a few concentric lines of growth. Aperture oval; peritreme sharp, extremely fragile. The shell length is up to 4 mm, the width up to 2.75 mm, and height up to 1.5 mm.
|
|
Brodmann area 4 refers to the primary motor cortex of the human brain. It is located in the posterior portion of the frontal lobe. Brodmann area 4 is part of the precentral gyrus. The borders of this area are: the precentral sulcus in front (anteriorly), the medial longitudinal fissure at the top (medially), the central sulcus in back (posteriorly), and the lateral sulcus along the bottom (laterally).
|
|
The forewings are light grey with a faint yellowish tinge and a slightly irregular fuscous line from the middle of the costa to the dorsum before the tornus, obscurely pale edged anteriorly, sometimes faint but with darker marks on the costa and in the middle. There is a scalloped dark fuscous terminal line. The hindwings are pale greyish, with a suffused grey terminal fascia.
|
|
The forewings are dark fuscous, faintly purplish tinged. There is a wedge-shaped ochreous-white mark from the costa near the apex and a fine white denticulate terminal line. The hindwings are dark fuscous, lighter anteriorly. There are broad median and dorsal prismatic-violet-tinged hyaline (glass like) longitudinal patches, confluent towards the base, the upper extending to about three-fourths, the lower nearly to the termen.
|
|
The wingspan is 27–28 mm. The forewings are brown, faintly rosy tinged, with a few scattered dark fuscous scales. The stigmata are small and dark fuscous, the first discal sometimes edged anteriorly by a small whitish dot, the plical obliquely beyond this. Small white subtriangular spots are found on the costa at two-fifths and two-thirds, the edge between these sometimes rosy.
|
|
They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. All toads are frogs, but not all frogs are toads. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (except in tailed frogs).
|
|
The diagnosis of retroperitoneal fibrosis cannot be made on the basis of the results of laboratory studies. CT is the best diagnostic modality: a confluent mass surrounding the aorta and common iliac arteries can be seen. On MRI, it has low T1 signal intensity and variable T2 signal. Malignant retroperitoneal fibrosis usually give uneven MRI signals, bulky, extend above the origins of renal arteries, or displace aorta anteriorly.
|
|
The spiral sculpture consists of a thickened band between the suture and the somewhat constricted anal fasciole. At the shoulder there is a blunt angulation, in front of which are two obscure threads followed by a more distinct thread on which the suture is laid. On the body whorl in front of the angulation there are about 18 threads growing smaller and more close-set anteriorly. There is no siphonal fasciole.
|
|
The crossing of these two sets of lines produces a finely cancellated sculpture over the whole surface, but the transverse lines are usually more evident on the convexity of the whorls, while the spiral lines are more conspicuous anteriorly, and on the siphon. The aperture is relatively large, oblong-elliptical, slightly obtusely angled posteriorly. The sinus is shallow, but distinct, evenly concave. The outer lip is elsewhere evenly convex.
|
|
The outer lip is thin, smooth inside, moderately arcuate, with a hump-like varix behind it. The inner lip and the straight columella are covered with a thin layer of enamel, raised anteriorly at the edge. The short siphonal canal is not deep and is hardly differentiated from the aperture.Dall (1919) Descriptions of new species of Mollusca from the North Pacific Ocean; Proceedings of the U.S. National Museum, vol.
|
|
The larger semilunar medial meniscus is attached more firmly than the loosely fixed, more circular lateral meniscus. The anterior and posterior horns of both menisci are secured to the tibial plateaus. Anteriorly, the transverse ligament connects the 2 menisci; posteriorly, the meniscofemoral ligament helps stabilize the posterior horn of the lateral meniscus to the femoral condyle. The coronary ligaments connect the peripheral meniscal rim loosely to the tibia.
|
|
It is white, with an ashy pale- brown epidermis. The aperture measures less than half the length of the shell. The suture is distinct, not channeled The anal notch is rather anterior, about as deep as wide, separated from the suture behind by a somewhat excavated area. The spiral sculpture consists of, in front of the suture, a plain, strong thread, in front of that three or four anteriorly diminishing threads.
|
|
To the right of the septum primum, the septum secundum begins to form. This thick, muscular structure initially takes on the same crescent shape as the septum primum, except that it originates anteriorly, whereas the septum primum originates posteriorly. As the septum secundum grows, it leaves a small opening called the foramen ovale. The foramen ovale is continuous with the ostium secundum, again providing for continued shunting of blood.
|
|
Dicerodiscus is an extinct genus from a well-known class of fossil marine arthropods, the trilobites. It lived during the early part of the Botomian stage, in China (Guizhou and Sichuan). Four species have been assigned to it. Dicerodiscus is unique for an eodiscoid in having conspicuous and curved spines that are attached anteriorly, and at their base are directed outward perpendicular to the midline, before gradually bending further backwards.
|
|
The size of an adult shell varies between 20 mm and 44 mm. This small to medium-sized shell is shaped like a small Conus geographus but with smaller coronations on the shoulder. The shell is subcylindrical, violaceous, with chestnut blotches, forming two interrupted bands, and faint lines of minute chestnut and white articulations. The aperture is very wide anteriorly caused by a concave lower half of the columella.
|
|
The chief action of abductor pollicis longus is to abduct the thumb at the carpometacarpal joint, thereby moving the thumb anteriorly. It also assists in extending and rotating the thumb. By its continued action it helps to abduct the wrist (radial deviation) and flex the hand. The APL insertion on the trapezium and the APB origin on the same bone is the only connection between the thumb's intrinsic and extrinsic muscles.
|

Hypomeron without pit. Anterior portion of prosternum at midline shorter than prosternal process, or as long as prosternal process, or longer than prosternal process. Lateral portion of prosternum in front of coxae shorter than mid length of procoxal cavity, or as long as mid length of procoxal cavity, or longer than mid length of procoxal cavity. Anterior edge of prosternum not produced anteriorly, or distinctly produced forming chin piece (rare).
|
|
The stigmata are black, on the margin of the angulated fascia, the plical somewhat before the first discal, the second discal sometimes absent, a black mark also on dorsal angle of the fascia. The costal edge of these markings is more or less tinged with blackish and there is an irregular line of black and rosy-brown scales along the termen. The hindwings are bluish grey, lighter anteriorly.
|
|
There are four white blotches, the first elongate, extending along the dorsum from one-fourth to three-fourths, widest anteriorly and reaching halfway across the wing, then irregularly attenuated, the second oval, beneath the costa slightly beyond the middle, third roundish, on the tornus, fourth semi oval, on the costa towards the apex. There is a slender irregular white streak along the termen. The hindwings are whitish grey.
|
|
Other potential synapomorphies include a hypertrophied tuber hypothesized for the attachment of the m. triceps brachii on the posterolateral surface of the proximal scapula blade. Unlike other archosauriforms that have a small tuber in the same location, the size of the tuber in erpetosuchids is exceptionally large in relation to the overall size of the scapula. Furthermore, as Krebs (1976) hypothesized the scapula blade slightly arc anteriorly in both taxa.
|
|
The amount of vertebrae are also diagnostic, having 34 in total. The swim bladder is the most accurate diagnostic feature, having two posterior extensions and two anterior extensions. The two anterior extensions extend forward and diverge to end on each side of the basioccipital above the auditory capsule. Two lateral extensions also commence anteriorly, each of them sending a blind tubule anterolaterally and then extending along the abdominal wall.
|
|
The superior border of the mastoid part is broad and serrated, for articulation with the mastoid angle of the parietal. The posterior border, also serrated, articulates with the inferior border of the occipital between the lateral angle and jugular process. Anteriorly, the mastoid portion is fused with the descending process of the squama above; below, it enters into the formation of the ear canal and the tympanic cavity.
|
|
The supraspinatous fossas are divided by a "secondary spine" and the bronchi are divided anteriorly. Otariids consist of two types: sea lions and fur seals. Sea lions are distinguished by their rounder snouts and shorter, rougher pelage, while fur seals have more pointed snouts, longer fore-flippers and thicker fur coats that include an undercoat and guard hairs. The former also tend to be larger than the latter.

Meyrick describes it -Antennae in male bipectinated. Forewings brown-grey, slightly purplish-tinged ; first, median, and second lines somewhat darker, especially on costa ; orbicular and reniform darker, outlined with pale ; subterminal line pale greyish-ochreous, edged anteriorly in middle with two small red-brown or black marks. Hindwings grey. Larva pale green or greenish-whitish ; dorsal, subdorsal, and spiracular lines whitish ; head pale greenish-ochreous, more or less blackmarked.

The Athyma perius male has black wings with a series of white markings, while the female is a blackish brown. The underside of the wings are ochre yellow with the white markings as on the upperside but heavily margined and defined with black. The antennae are black and there is a spot of ochre between the eyes. The thorax has a band or two of bluish spots anteriorly and posteriorly.
|
|
The forewings are rather dark bronzy fuscous, obscurely irrorated (sprinkled) with grey whitish. The stigmata are cloudy, obscure, dark fuscous, the discal approximated, the second transverse, the plical rather obliquely before the first discal. There is a distinct angulated thick dark coppery-fuscous line from three-fourths of the costa to the tornus, edged anteriorly by a faint line of whitish irroration. The apical edge is coppery bronze.

The digestive tract of sipunculans starts with the esophagus, located between the introvert retractor muscles. In the trunk the intestine runs posteriorly, forms a loop and turns anteriorly again. The downward and upward sections of the gut are coiled around each other, forming a double helix. At the termination of the gut coil, the rectum emerges and ends in the anus, located in the anterior third of the trunk.
|
|
The forewings are leaden grey with a blackish dot towards the costa near the base, finely whitish edged above. There is a narrow direct blackish finely whitish-edged fascia at one-third. There are two blackish dots on the end of the cell, the lower rather posterior. There is a slender transverse fascia of blackish irroration (sprinkling) at three-fourths, edged with ochreous-whitish suffusion anteriorly towards the costa.

The Viper's Bugloss (Hadena irregularis) is a species of moth of the family Noctuidae. It is found in Europe. The wingspan is 32–36 mm.Meyrick describes it - Forewings whitish-ochreous, irregularly suffused with pale ochreous brownish ; first and second lines edged externally with ochreous brownish, internally with dark brown ; median line ochreous brown ; orbicular and reniform outlined with pale ; subterminal line pale, edged anteriorly with ochreous-brown ; termen unmarked; cilia barred.
|
|
The lateral line has an irregular zigzag pattern. The head is flattened anteriorly with a terminal mouth. There are three pairs of thread- like barbels, one pair maxillary and two pairs mandibular. The dorsal fin and pectoral fins have large spines; the dorsal fin spine has a lower degree of serration than the pectoral fin spines, which is always serrated strongly on the entire length of both margins.

Despite the similarity of name, an epispadias is not a type of hypospadias, and involves a problem with a different set of embryologic processes. Women can also have this type of congenital malformation. Epispadias of the female may occur when the urethra develops too far anteriorly, exiting in the clitoris or even more forward. For females, this may not cause difficulty in urination but may cause problems with sexual satisfaction.

Primitive macropodines have the straight molar row in common. Ekaltadeta also has plesiomorphic features in that the dental canal and masseteric canal are separated anteriorly, below premolar three and the first molar, with the masseteric canal terminating in a cul-de-sac.

The length of the shell attains 13 mm, its width 4 mm. (Original description) The specimens of this small shell are quite imperfect; The spire is long and slender and contains six convex whorls showing in the best specimen. The suture is impressed with a well-marked border anteriorly. The whorls show eighteen radial ridges, which extend from suture to suture and are strongly twisted forward at the anterior end.
|
|
There is no clear distinction between body parts (or tagmata) such as head, trunk and tail, although the frontal segment is rounded anteriorly, and the posterior segments become narrower, the final one ending rounded with a small backward directed spine. Each segment overlaps the front of the following one. There is one median node or spine and two lateral nodes or spines on every segment. Camptophyllia is known from 11 fossils.
|
|
The moth flies from June to September depending on the location. In the south of the area there is occasionally a second brood. Larva slate grey, with thin longitudinal lines, a transverse black spot each across the back anteriorly, in the centre and behind, and subdorsally there are longitudinal rows of small reddish yellow warts. The larvae feed on lichen and algae growing on trees, especially oak, walls and stones.
|
|
The internal, subepidermal vas deferens extends along the right body side to the right rhinophore connecting to the anterior male copulatory organs. The short posterior-leading vas deferens joins the large, tubular prostate gland. Anteriorly, the long and highly coiled, muscular ejaculatory duct arises from the prostate. The ejaculatory duct enters the muscular penis at its base and discharges at the top of the penis through a long hollow stylet.
|
|
In the lower half of each whorl these are crossed by three spiral threads, in the intervals of which there are about three very low spirals. On the body whorl there are about 20 major spirals. They are closer anteriorly, where there are fewer of the low minor spirals, there being four in the upper intervals, down to one in the lower. The aperture is of nearly the same width throughout.
|
|
The supraorbital nerve branches from the frontal nerve midway between the base and apex of the orbit. It travels anteriorly above the levator palpebrae superioris and exits the orbit through the supraorbital foramen (or notch) in the superior margin orbit. It exits the orbit lateral to the supratrochlear nerve. It then ascends onto the forehead beneath the corrugator supercilii and frontalis muscles and divides into a medial branch and lateral branch.
|
|
The periphery of the body whorl is marked by a cord fully as strong as those posterior to it. The base of the shell is moderately prolonged, slightly rounded, marked by three spiral cords which are almost as strong as those on the spire and of about equal spacing with them. The aperture is feebly channeled posteriorly, decidedly so anteriorly. The outer lip is rendered sinuous by the spiral cords.
|
|
It shows strong ventral recurving and the dorsal surface is convex, smooth and creamy white in colour. The bone's long, straight spine and posterior quarter are covered with an ochre-coloured smooth glaze. The dorsal median rib of the bone is indistinct and broadens slightly anteriorly; the bone's ribs are bordered laterally by obvious grooves and the lateral ribs are marked. The whole margin of the cuttlebone is surrounded by chitin.
|
|
The spinal cavity (or vertebral cavity or spinal canal) is the cavity that contains the spinal cord within the vertebral column, formed by the vertebrae through which the spinal cord passes. It is a process of the dorsal body cavity. This canal is enclosed within the vertebral foramen of the vertebrae. In the intervertebral spaces, the canal is protected by the ligamentum flavum posteriorly and the posterior longitudinal ligament anteriorly.

|
A molecular study on the phylogeny of the subfamily Geoplaninae nested the genus Supramontana inside the genus Luteostriata. The two genera formed a monophyletic clade with the genus Issoca. The clade is supported by at least one synapomorphy, the presence of a cephalic retractor muscle derived from the longitudinal cutaneous ventral musculature that anteriorly dissipates by detaching its fibers, making them open in a fan-like fashion towards the body margins.
|
|
In more severe cases, fractures can occur to any of the cervical vertebrae as they are suddenly compressed by rapid deceleration. Again, since the vertebral foramen is large there is less chance of spinal cord involvement. The worst-case scenario for these injuries is that dislocation or subluxation of the cervical vertebrae occurs. This often happens at the C2 level, where the body of C2 moves anteriorly with respect to C3.
|
|
The presacral fascia lines the anterior aspect of the sacrum, enclosing the sacral vessels and nerves. It continues anteriorly as the pelvic parietal fascia, covering the entire pelvic cavity. The presacral fascia is limited postero-inferiorly, as it fuses with the mesorectal fascia, lying above the levator ani muscle, at the level of the anorectal junction. These two fascias have been erroneously confused, though they are in fact, separate anatomical entities.

|
The vagina includes a sclerotized part, which is a complex structure. The redescription by Kritsky, Bakenhaster & Adams in 2015 includes the following: Body flattened dorsoventrally. Tegumental scales with rounded anterior margins extending from peduncle anteriorly into posterior trunk. Cephalic region broad, with two terminal and two bilateral poorly developed cephalic lobes, three bilateral pairs of head organs, pair of bilateral groups of cephalic-gland cells at level of pharynx.

The arrangement of soft tissue and any additional articulations connecting these elements is collectively known as the jaw suspension. There are several archetypal jaw suspensions: amphistyly, orbitostyly, hyostyly, and euhyostyly. In amphistyly, the palatoquadrate has a postorbital articulation with the chondrocranium from which ligaments primarily suspend it anteriorly. The hyoid articulates with the mandibular arch posteriorly, but it appears to provide little support to the upper and lower jaws.

L. homeyeri Tancre (57c) is somewhat more narrow-winged than the previous forms [sydi, camilla, helmanni, doerriesi] , but very similar lo them, being more delicately marked. The middle spots of the discal row of the forewing as in doerriesi project less distally, the band of the hindwing however is anteriorly narrower and there is a row of distinct venata. small white spots in the marginal area of the hindwing.

Life restoration of D. menneri Like the other chasmataspidids, D. menneri was a small arthropod. The biggest specimen, PIN 5116/1, reached a total length of 2.64 centimetres (1.04 inches). This size is, however, notable among diploaspidids. The prosoma (head) was subquadrate (almost square) to parabolic (nearly U-shaped), with a carapace (dorsal plate of the prosoma) rather vaulted and somewhat rounded anteriorly and laterally and flat medianly and posteriorly.
|
|
Compared to other cetaceans, the infraspinous fossa is smaller, the caudal border is less curved and not oriented posteriorly. The glenoid cavity is very shallow and directed posteriorly, rather than ventrally like in other cetaceans. Likewise, the oddly folded acromion is pointing ventrally and posteriorly, and not anteriorly as in other cetaceans. Unlike in other basilosaurids, the humerus of Ancalecetus is flattened and has a relatively small head.
|
|
On the head there are two thin tentacles, located on the side of the trunk, about which there are the eyes, the tentacles are about 20 mm. The pallial siphon, located anteriorly, measuring 15 mm. The small radula is rachiglossa, comprising a series of transverse teeth acuminata, three for the first row is a lateral tooth, the second (middle) is a tooth rachidian and the last is a lateral tooth.

|
The extracellular signals that propagate through the extracellular matrix surrounding neurons play a prominent role in axonal development. These signaling molecules include proteins, neurotrophic factors, and extracellular matrix and adhesion molecules. Netrin (also known as UNC-6) a secreted protein, functions in axon formation. When the UNC-5 netrin receptor is mutated, several neurites are irregularly projected out of neurons and finally a single axon is extended anteriorly.
|
|
The upper surface is broadly radiately maculate with crimson, the flames not extending below the periphery, which, with the base, is dotted with the same shade. The spire is usually attenuated toward the acute rose-colored apex. The about 6 whorls are convex, the last one deflected anteriorly. They are spirally sculptured with about 18 closely granose cinguli, of which 5 to 8 principal ones are above the periphery.
|
|
The curved and straight sections intersect below the 10th to 12th soft rays of the second dorsal fin. The breast is devoid of scales, with the scaleless area extending to the origin of the pelvic fins and up to the base of the pectoral fins. Both jaws have bands of villiform teeth, which are widest anteriorly. It has a total of 20 to 27 gill rakers and 24 vertebrae.
|
|
The forewings are whitish, the dorsal half ochreous tinged and more or less sprinkled with dark fuscous. The stigmata are dark fuscous, rather obscure, with the plical obliquely beyond the first discal. There is a wedge-shaped dark fuscous blotch, suffused beneath with yellow ochreous, along the costa from the middle to three- fourths, acute anteriorly. There is also some ochreous suffusion towards the apex, edged on the costa with blackish.
|
|
The feeding method of tadpole shrimps is similar to that proposed for the ancestral crustacean. The anterior appendages (second pair to tenth pair) stir sediments and swirl muddy water into the wide, midventral food groove. The gnathobases (inward-facing lobes at the base of the leg) guide food anteriorly to the mouth. The large flat exopods (outward-facing lobes at the end of the leg) stir and lift the sediments.
|
|
The forewings are whitish, more or less sprinkled or irrorated with grey, especially on the dorsal two-thirds. The costal edge is blackish anteriorly, with a fine oblique black strigula at one- fourth, and an elongate black spot in the middle. There are indistinct dark fuscous dots obliquely placed above and below the fold at one-fourth. The stigmata are indistinct and dark fuscous, the plical obliquely before the first discal.

The channels between the keels are about equal to the keels in width and are crossed by numerous very slender raised threads, which extend up on the sides of the keels but do not cross them. About five of these threads fall in the space between two tubercles on the spire, in the first supra-peripheral groove. The oval aperture is large, effuse anteriorly. The posterior angle is obtuse.
|
|
The forewings are ochreous brown, considerably sprinkled with dark fuscous and with the base of the costa infuscated. The discal stigmata are dark fuscous, the first forming a rather large dot, the second a roundish spot of irroration (sprinkles) edged anteriorly by a transverse mark, lying below the middle and touching the groove. There is also a streak of dark fuscous suffusion along the termen. The hindwings are grey.
|
|
The forewings are deep orange, with the markings shining purplish leaden grey, with a small basal patch. There is a small spot in the disc at one-fifth and a very large patch occupying the entire apical two-thirds except towards the margins anteriorly, enclosing an irregularly triangular patch of ground colour in the disc at about three- fifths. The hindwings are grey.Journal of the Bombay Natural History Society.
|
|
The forewings are light shining bronzy fuscous, the costa suffused with ochreous yellow, except a basal spot. The dorsum is suffused with ochreous yellow anteriorly, connected with the costal suffusion near the base, and by a bar at one-fifth. There is an indistinct ochreous-yellowish transverse mark below the middle of the disc. The hindwings are light grey, yellowish tinged, towards the costa suffused with yellow ochreous.
|
|
A long fin extends posteriorly, along half the tail fin, forming the second dorsal fin. Evidence of the first dorsal fin is incomplete, but scientists believe that a fossil element found was its fin support. Ventrally, the large anal fin extends back beneath the anterior part of the tail fin. Scales that overlap anteriorly have been found, the smallest being only 5 mm across, and the largest 22 mm.

Zeliszkella is a genus of trilobite in the order Phacopida, with species of average size. Species are known from the Middle and Upper Ordovician and have been found in the Czech Republic, France, Morocco, Portugal and Spain. Z. torrubiae The cephalon has a rather narrow frontal area, and the anterior sections of the facial sutures run close to frontal lobe anteriorly. The large mosaic (schizochroal) eyes reach far backward.
|
|
Where the premaxilla meets with the naris there is a straight suture instead of the Varanopid typical V shaped one. The jugal and quadratojugal have pinched tubercular ornamentation on the lateral sides. The quadratojugal has the elongated and slender shape distinct to the Varanopids, as well as a slender groove on the dorsal edge. This serves as an attachment for the squamosal, which extends anteriorly under the lateral temporal fenestra.
|
|
Two of the juvenile individuals of the aggregate have radii with a slightly bowed shape. The metacarpals and phalanges of H. scholtzi have a long and slender shape to them. Pelvic girdles are preserved in both fossils and shows the anteroposteriorly elongated ischium typical of synapsids as well as a blade like distal shape and a well-developed pubic foramen. The ilium is also elongated and rises anteriorly above the acetabulum.
|
|
The frontal nerve branches from the ophthalmic nerve immediately before entering the superior orbital fissure. In then travels superolateral to the annulus of Zinn between the lacrimal nerve and inferior ophthalmic vein. After entering the orbit it travels anteriorly between the roof periosteum and the levator palpebrae superioris. Midway between the apex and base of the orbit it divides into two branches, the supratrochlear nerve and supraorbital nerve.
|
|
Hindwing: some two or three obscure dark subterminal spots towards the tornus. In some specimens the series complete from apex to tornus, more obscure anteriorly than posteriorly. Forewings and hindwings: both with slender dark anteciliary line. Underside: ground colour slightly paler, but the markings very similar to those in the male; the transverse brown bars beyond apex of cell on the forewing longer, almost extended to the dorsal margin.

|
The mandibular incisive canal (indicated here by coral green arrows) continuing anteriorly (to the right) from the mandibular canal (purple arrows) after the mental foramen (light green circle). The mental foramen is one of two foramina (openings) located on the anterior surface of the mandible. It transmits the terminal branches of the inferior alveolar nerve and vessels (the mental artery). The mental foramen descends slightly in toothless individuals.
|
|
The wingspan is 19–20 mm. The forewings are brownish-ochreous, paler towards the costa anteriorly. The first discal stigma is indistinct and fuscous, sometimes with a faint oblique shade from this to the dorsum. There is an indistinct oblique fuscous line from the middle of the costa to the dorsum before the tornus and a faint curved line from three-fourths of the costa to the tornus sometimes indicated.

Anatomical drawing of the female pelvis The pelvic girdle consists of the two hip bones. The hip bones are connected to each other anteriorly at the pubic symphysis, and posteriorly to the sacrum at the sacroiliac joints to form the pelvic ring. The ring is very stable and allows very little mobility, a prerequisite for transmitting loads from the trunk to the lower limbs. Thieme Atlas of Anatomy (2006), p.
|
|
The axial sculpture consists of, on the spire, obscure nodulations at the shoulder (about 15 on the penultimate whorl) which do not form ribs and are absent from the body whorl. The incremental lines are fine but obscure. Beside these there are minute, anteriorly obliquely retractive lines somewhat microscopically reticulated by the lines of growth.tTere is no spiral sculpture except on some specimens a few obsolete lines on the base.
|
|
There are two coronary sulci in the heart including left and right coronary sulci. The left coronary sulcus originates posterior to the pulmonary trunk, and travels inferiorly separating the left atrium and left ventricle. The location of the left coronary sulcus is marked by the circumflex branch of left coronary artery and coronary sinus. Similarly, the right coronary sulcus begins anteriorly and superiorly on the sternocostal surface of the heart.
|
|
The dorsal nasal artery is a terminal branch of the ophthalmic artery in the superomedial orbit. It passes anteriorly to exit the orbit between the trochlea superiorly and the medial palpebral ligament inferiorly. First it gives a branch to the lacrimal sac. Then it bifurcates into a branch that anastomoses with the terminal part of the facial artery and a branch that travels along the dorsum of the nose.
|
|
Functional zygosphenes and zygantra were found on two of the cervical vertebrae. Vertebral hypapophyseal peduncles were found on all four vertebrae and are very short and end as small laterally compressed oval facets. These facets are posteriorly inclined and located posteriorly on the ventral surfaces of the centra. The synapophyses are large, located anteriorly on the centra, and do not extend below the ventral margin of the centrum.
|
|
The anal fin consists of 2 detached spines anteriorly followed by 1 spine and 17 or 18 soft rays. Both the anal and dorsal fins are elongate, with the dorsal lobe being over twice the length of the head. The pectoral fin is falcate, and also longer than the head. The lateral line has a short, strong anterior arch, with 40 to 45 scutes on the straight posterior section.
|
|
They are marked by numerous slender, wavy subequal and subequally closely spaced spiral striations, of which about 33 occur upon the last turn between the summit and the periphery. The periphery of the body whorl is marked by a slender raised keel, decidedly angulated. The base of the shell is short, moderately rounded. It is narrowly attenuated anteriorly to reinforce the columella, sculptured like the posterior portion of the whorls.
|
|
From there it diffuses anteriorly, laterally to the growth direction of the limb. In the mutant mirroring smaller ectopic expression in a new organiser region is seen on the posterior side of the limb. This ectopic expression causes cell proliferation delivering the raw material for one or more new digits. An identical sequence at this position serves the same function in human and mice and cause similar symptoms when mutated.

Soluta is an extinct class of echinoderms that lived from the Middle Cambrian to the Early Devonian. The class is also known by its junior synonym Homoiostelea. Soluta is one of the four "carpoid" classes, alongside Ctenocystoidea, Cincta, and Stylophora, which made up the obsolete subphylum Homalozoa. Solutes (or solutans) were asymmetric animals with a stereom skeleton and two appendages, an arm extending anteriorly and a posterior appendage called a homoiostele.
|
|
The anal fin has two spines followed by a single spine and 15 or 16 soft rays. The pectoral fin is long and curved, extending beyond the junction of the straight and curved sections of the lateral line. The body appears to be scaleless, but on closer inspection has minute, deeply embedded scales. The lateral line is strongly curved anteriorly, with a section of 6 to 11 scutes toward the tail.
|
|
The periphery of the body whorl is marked by a spiral groove. The base of the body whorl is well rounded, and marked by eight spiral cords which grow successively weaker and closer spaced from the periphery to the umbilical area. The wide grooves between the spiral cords are marked by slender, raised, axial threads, which correspond to the ribs on the spire. The aperture is ovate and somewhat effuse anteriorly.
|
|
The base of the shell is well rounded, marked by six slender spiral keels, which are a little less strongly developed and more closely spaced at the umbilical area than at the periphery. The grooves separating these keels are about twice as wide as the keels, crossed by slender axial threads which correspond to the ribs. The aperture is ovate, somewhat effuse anteriorly. The posterior angle is obtuse.
|
|
The periphery and the base of the body whorl are inflated, the latter marked by lines of growth and eight strongly incised, punctate spiral lines, which are a little less strongly impressed and a little more closely spaced at the umbilical area than at the peripheral part of the base. These lines equal those of the spire in strength. The sutures are constricted. The aperture is very large, somewhat effuse anteriorly.
|
|
Plastron is angulate laterally in the young. The anterior and posterior lobes are rather narrow and shorter than the width of the bridge, truncate anteriorly and are openly notched posteriorly. The longest median suture is between the abdominals and the shortest is between the gulars, which equals about one half that between the humerals. The suture between gulars and humerals forms an obtuse angle, as does that between humerals and pectorals.
|
|
The forewings are pale greyish, irregularly sprinkled with dark fuscous and blackish, forming fine strigulae along the costa. The discal stigmata is small, black and rather approximated, while the second is hardly beyond the middle. There is a blotch of dark grey suffusion on the costa at two-thirds and a blackish apical dot, edged anteriorly by a slight indistinct whitish mark. The hindwings are grey, but paler towards the base.
|
|
When the mouth is closed the meniscus is bordered medially and superiorly by the glenoid fossa of the petrous portion of the temporal bone. When the mouth is opened maximally, the meniscus is distracted anteriorly and inferiorly along the slope of the inferior portion of the temporal bone towards the tubercle, or articular eminence, in order to remain interposed between the condyle and the temporal bone in all jaw positions.
|
|
The forewings are grey whitish, with the apex of scales dark grey, forming a close rather irregular striolation, more or less largely suffused with ochreous brown except anteriorly. There are three small black dots in a longitudinal row in the disc from one-fourth to three-fourths and several dark grey transverse spots from the costa, as well as a black apical dot. The hindwings are grey.Exotic Microlepidoptera.
|
|
The posterior angle is acute. The outer is lip decidedly curved backward anteriorly, very thick within but beveled to form a sharp edge. The columella is extremely short, somewhat reflected and connected posteriorly with the very strong parietal callus. This callus is fully as thick as the edge of the outer lip and connects with it at the posterior angle of the aperture, thus forming a complete periostracum.
|
|
They are subtabulately shouldered at the summit, marked by numerous fine lines of growth and equally abundant, loosely placed, wavy spiral striations. These lines of growth and spiral markings give the surface a finely reticulated appearance when viewed under high magnifications. The periphery and base of the body whorl are decidedly rounded and inflated, marked like the space between the sutures. The aperture is large, suboval, slightly effuse anteriorly.
|
|
The forewings are light grey finely speckled with white and with the costal edge finely white except towards the apex. The stigmata are cloudy, with the dark grey plical obliquely beyond the first discal, the second discal forming an oblique mark. There is an elongate black mark on the costa beyond the middle, pointed anteriorly, as well as a small black apical dot. The hindwings are light grey.
|
|
The forewings are dark fuscous, irrorated (sprinkled) with whitish. The stigmata are very indistinct, cloudy and dark fuscous, the plical obliquely before the first discal. There is a nearly straight or slightly curved ochreous-whitish transverse streak from two-thirds of the costa to the dorsum before the tornus, sometimes produced anteriorly along the costa. The apical area beyond this is darker, with some undefined blackish marginal dots.
|
|
The color pattern consists of a brownish green to green to grayish green ground color overlaid with a series of pairs of crossbars. These crossbars are dark brown or black and bordered with yellow or yellowish white. This pattern usually breaks up anteriorly, resulting in spots of both colors. Occasionally, a row of yellowish ventrolateral spots, each covering 1-3 scales, is present and extends to the tail.
|
|
This configuration resembles that of the procolophonids, turtles, and neopiapsids and results in the exclusion of the lacrimal from the posterior border of the nares. Slightly more than one third of the total length of the skull is contributed by the frontal. It is constricted anteriorly by the prefrontals, but otherwise expanded above the orbits. Generally, in early amniotes the largest element was the occiput of the supraoccipital.
|
|
The middle colic artery is a branch of the superior mesenteric artery that mostly supplies the transverse colon. It arises just below the pancreas. It passes inferiorly and anteriorly between the layers of the transverse mesocolon, and divides into left and right branches. The right branch anastomoses with the right colic artery, and the left anastomoses with the left colic artery, a branch of the inferior mesenteric artery.
|
|
The wingspan is 17–18 mm. The forewings are dark reddish brown with the costal edge dull reddish on the basal two-fifths and a very small carmine-white mark on the costa at two- fifths, the extreme costal edge between this and the sinuation dark fuscous. There is a wedge-shaped white spot on the costal sinuation, edged anteriorly with carmine red. The hindwings are dark fuscous.
|
|
There is an irregular white ring in the middle of the disc, partly tinged with ochreous, anteriorly projecting into the preceding whitish fascia. There is also a raised blackish transverse mark extending from the tornus more than halfway across the wing, surmounted with pale ochreous. Beyond this is some whitish suffusion towards the costa and some black irroration (sprinkles) towards the apex. The hindwings are grey, darker posteriorly.

The abdominal aorta begins at the level of the diaphragm, crossing it via the aortic hiatus, technically behind the diaphragm, at the vertebral level of T12. It travels down the posterior wall of the abdomen, anterior to the vertebral column. It thus follows the curvature of the lumbar vertebrae, that is, convex anteriorly. The peak of this convexity is at the level of the third lumbar vertebra (L3).

Underside of blue Mormon Males have the upper wings rich velvety black. The forewing has a postdiscal band composed of internervular broad blue streaks gradually shortened and obsolescent anteriorly, not extended beyond interspace 6. The hindwing has the terminal three-fourths beyond a line crossing the apical third of the cell pale blue, or greyish blue, with superposed postdiscal, subterminal and terminal series of black spots—the postdiscal spots elongate, inwardly conical; the subterminal oval, placed in the interspaces, the terminal irregular, placed along the apices of the veins and anteriorly coalescing more or less with the subterminal spots. The underside is black with and on the base of the cell in the forewing is an elongate spot of dark red; the postdiscal transverse series of streaks as on the upperside but grey tinged with ochraceous and extended right up to the costa; in some specimens similar but narrow streaks also in the cell.

It differs from Graphium antiphates chiefly in the greater width of the black markings on the upperside, especially of the basal and subbasal bands that cross the forewing, both of which also extend to the dorsum. On the hindwing the black markings of the underside on the basal and discal areas are not only seen by transparency from below, but are actually represented, though only partially, by black scaling; the width of the dark grey terminal portion is also greater, and it has a tendency to turn to dusky black anteriorly, so that the sub-terminal series of black lunules are obscured anteriorly and are difficult to make out. Underside: markings similar to those of the typical form, but broader; forewing with the discal transverse band that reaches from costa to vein 1; hindwing: the black bands that cross the cell broader and proportionately closer together. Has a 94–100 mm expanse.

Erethistes species lack a thoracic adhesive apparatus, a smooth to granulate anterior margin on a strong dorsal fin spine, a papillate upper lip, and 8-12 anal fin rays. The pectoral fin spine is serrated anteriorly and posteriorly. The anterior margin of the pectoral fin spine either has serrations all pointing toward tip of spine; arranged in divergent pairs; or outwardly directed and not divergent. The head is large and broad with a conical snout.

The axial sculpture consists of more or less distinct incremental lines, and on the upper spire of about 15 very oblique anteriorly protracted riblets chiefly visible at the shoulder and obsolete on or entirely absent from the last two whorls. The anal sulcus is wide, deep, rounded, the fasciole slightly impressed. The outer lip is thin, sharp and arcuately produce The inner lip is erased. The columella is short, white, obliquely attenuated in front.

The Fitzroy River turtle is light to dark brown in color and grows to approximately 260 mm in carapace length. The shells of hatchlings (up to 95 mm long) are highly serrated while adults have rounded, smooth-edged shells. The plastron is lighter in color and tapers anteriorly and posteriorly. The carapace is highly reticulated to the naked eye, but this resolves as a series of parallel ridges with occasional cross ridging under low magnification.

Thomas's pika measures in length, and weighs . The fragile skull is broader anteriorly, and smaller, flatter, and narrower than other pika species. The greatest skull length is . The anterior palatine foramen (funnel-shaped opening in the bony plate of the skull, located in the roof of the mouth, immediately behind the incisor teeth where blood vessels and nerves pass) and the palatal foramen are attached, and there is no oval foramen above the frontal bone.

These pass gradually into slightly oblique, rounded riblets, which begin in front of the notch-band with a slight shoulder, then continue across the whorl, and are somewhat attenuated by the time they reach the suture. Of these there are about fifteen on the body whorl, less distinct anteriorly. The lines of growth are tolerably prominent, and especially so on the body whorl. Of the revolving sculpture there is little or none.

The shell contains 7 whorls including a protoconch of two depressed whorls. Its sculpture consists of eight thick and prominent ribs to a whorl These descend the shell vertically and continuously; on the base they are slightly flexed, and each terminates anteriorly in a bead. Both ribs and interstices are engraved by very minute and dense spiral striae. The snout is traversed by a few coarse spirals, which cease at the bead row.

The paravertebral block provides unilateral analgesia, but bilateral blocks can be performed for abdominal surgeries. Since it is a unilateral block, it may be chosen over epidurals for patients who can't tolerate the hypotension that follows bilateral sympathectomy. The paravertebral space is located a couple centimeters lateral to the spinous process and is bounded posteriorly by the superior costotransverse ligament and anteriorly by the parietal pleura. Complications include pneumothorax, vascular puncture, hypotension, and pleural puncture.

They are broad anteriorly (4–7 mm), white or whitish, in age flushed with pink, often with sordid-brownish stains, and with edges pallid and even. The stem is long, thick, very brittle and cartilaginous, equal, and tubular. It sometimes has a well-developed pseudorrhiza that resembles white cotton, and the base is covered with stiff white hairs, and often it stains reddish brown. The surface has fine straight or sometimes twisted longitudinal striations.

Like all Agnostida, Dicerodiscus is diminutive and the headshield (or cephalon) and tailshield (or pygidium) are of approximately the same size (or isopygous) and outline. The central raised area of the cephalon (or glabella) is conical and without transverse furrows. The most backward part of the glabella (called occipital ring or LO) usually carries small spine. The cephalon carries a pair of long, anteriorly fixed spines, running sideways from frontal border before curving gradually backwards.

In fact, species of Allopseudaxine have a large body tapering anteriorly, and a unilateral, oblique haptor, (which means that they have a single oblique row of clamps,) giving them a triangular appearance. By this triangular shape, they resemble Allopseudaxine. However, species of Allopseudaxinoides can be distinguished from Allopseudaxine by a complete absence of vaginae or the presence of rudimentary ones, the presence of thickenings of clamps capsule, and an accessory clamp sclerite.

There is a large irregular cuneiform (wedge-shaped) patch from the base below the costa, its lower edge emitting a long slender streak along the inner margin to the anal angle. There is also a large irregular lunate mark in the middle of the wing, connected with the basal patch anteriorly by a short bar. The hindmarginal line is narrow and yellowish. The hindwings are pale fuscous, with a pale yellow basal patch.

The last vertebra is convex anteriorly and posteriorly, and diagnostically the middle vertebrae are strongly compressed in width. Like other derived titanosaurs, all caudal vertebrae of Neuquensaurus are strongly and vertically compressed. There is a prominent ventral depression like in Saltasaurus and Rocasaurus, but contrasting the other genera there is no ridge dividing this depression. Additionally, the neural spines of vertebrae become progressively more reclined, and a prespinal lamina is present in all vertebrae.

In human anatomy, the left and right posterior communicating arteries are arteries at the base of the brain that form part of the circle of Willis. Each posterior communicating artery connects the three cerebral arteries of the same side. Anteriorly, it connects to the internal carotid artery (ICA) prior to the terminal bifurcation of the ICA into the anterior cerebral artery and middle cerebral artery. Posteriorly, it communicates with the posterior cerebral artery.

Head small, body long and slender anteriorly; scales on thickest part of body juxtaposed; 5-6 maxillary teeth behind fangs; 17-21 scale rows around neck, 30-36 around thickest part of body (increase from neck to midbody 18-24); ventrals divided by a longitudinal fissure; prefrontal in contact with third upper labial; ventrals 220-287. Total length males 950 mm, females 1025 mm; tail length males 80 mm, females 95 mm.

Hydrophis fasciatus has a small head, long body and is slender anteriorly. The scales on thickest part of body are subquadrangular or hexagonal in shape, juxtaposed or slightly imbricate. It has 5-6 maxillary (upper jaw bone) teeth behind fangs and 2 anterior temporals. Body scales in 28-33 rows around the neck, 47-58 around midbody (increase in number of rows from neck to midbody 20-27); ventral scales 414-514 (average 460).

The anterior teeth were angled anteriorly, while the posterior teeth were shorter and more upright. The upper and lower teeth interlocked; according to Bennett (2013) they formed a basket for sieving food items from water, though the lack of a pumping mechanism suggests a function more akin to spoonbill jaws, wading with the jaws open and closing them when catching individual prey, much as in other ctenochasmatoids.Wilton, Mark P. (2013). Pterosaurs: Natural History, Evolution, Anatomy.

Rubeostratilia is differentiated from other amphibamiforms by: (1) a pterygoid sutured only to the ectopterygoid anteriorly; and (2) the presence of four, equally sized foramina along the surface of the lacrimal that forms the anterior orbital margin. It shares a number of features with Pasawioops mayi, which at the time was known only from the Richards Spur locality in Oklahoma but which was subsequently reported from the Archer City Formation in Texas.

The infraorbital nerve travels with the infraorbital artery and vein. It branches from the maxillary nerve in the pterygopalatine fossa and travels through the inferior orbital fissure to enter the orbit. It runs anteriorly along the floor of the orbit in the infraorbital groove to the infraorbital canal of the maxilla. Within the infraorbital canal it has three branches, the posterior superior alveolar nerve, middle superior alveolar nerve and anterior superior alveolar nerve.

The crura are the proximal portions of the arms of the wishbone. Ending at the glans of the clitoris, the tip of the body bends anteriorly away from the pubis. Each crus (singular form of crura) is attached to the corresponding ischial ramus – extensions of the copora beneath the descending pubic rami. Concealed behind the labia minora, the crura end with attachment at or just below the middle of the pubic arch.

The kazacharthrans are distinguished from tadpole shrimp in that they were much larger (carapace length ranging from 0.6 to 5 centimeters), had uniquely shaped, heavily sclerotized, heavily mineralized carapaces, and plate-shaped telsons The carapace, or headshield had a distinctive pattern of tubercles, typically with a central-anteriorly located tubercle that may or may not have housed the compound eyes, and other, distinctively shaped tubercles that may represent attachment sites for mandibles.

The forewings are yellow ochreous, variably spotted and blotched with fuscous except towards the costa anteriorly, especially around the stigmata, along the dorsum and termen, and towards the costa beyond the middle, but these markings are sometimes little developed. The costa is dotted with dark fuscous on the anterior half, the edge black towards the base. The stigmata is black, distinct, with the plical obliquely before the first discal. The hindwings are light grey.

The so-called "brush" is not fibrous as was originally believed, but consists of a number of parallel, membranous tubules made of globular calcified cartilage. The brush base and basal plate are covered in a thin, acellular bone layer. Zangerl asserts that these tubules are similar to erectile tissues in humans, and thus the complex may have been inflatable. The complex itself is covered in up to nine rows of large denticles pointing anteriorly.

Like most marsupials, female sugar gliders have two ovaries and two uteri; they are polyestrous, meaning they can go into heat several times a year. The female has a marsupium (pouch) in the middle of her abdomen to carry offspring. The pouch opens anteriorly, and two lateral pockets extend posteriorly when young are present. Four nipples are usually present in the pouch, although reports of individuals with two nipples have been recorded.
