In the past, anatomists made little distinction between the posterior ciliary arteries and the short and long posterior ciliary arteries often using the terms synonymously. However, recent work by Hayreh has shown that there is both an anatomic and clinically useful distinction.Hayreh, SS. "Posterior Ciliary Artery Circulation In Health and Disease" Investigative Ophthalmology and Visual Science 2004 Mar;45(3):749-757.

The posterior division of the first cervical or suboccipital nerve is larger than the anterior division, and emerges above the posterior arch of the atlas and beneath the vertebral artery. It enters the suboccipital triangle and supplies the muscles which bound this triangle, viz., the Rectus capitis posterior major, and the Obliquus capitis superior and Obliquus capitis inferior; it gives branches also to the Rectus capitis posterior minor and the Semispinalis capitis. A filament from the branch to the Obliquus capitis inferior joins the posterior division of the second cervical nerve.
The gastrocnemius muscle is superficial to (closer to the skin than) the soleus, which lies below the gastrocnemius. The plantaris muscle and a portion of its tendon run between the two muscles. Deep to it (farther from the skin) is the transverse intermuscular septum, which separates the superficial posterior compartment of the leg from the deep posterior compartment. On the other side of the fascia are the tibialis posterior muscle, the flexor digitorum longus muscle, and the flexor hallucis longus muscle, along with the posterior tibial artery and posterior tibial vein and the tibial nerve.
The marginal arteries supply blood to the superficial portions of the right ventricle. On the posterior surface of the heart, the right coronary artery gives rise to the posterior interventricular artery, also known as the posterior descending artery. It runs along the posterior portion of the interventricular sulcus toward the apex of the heart, giving rise to branches that supply the interventricular septum and portions of both ventricles.
The cytoplasm of the egg not only determines cell fate, but also determines the dorsal/ventral axis. The cytoplasm in the vegetal pole specifies this axis and removing this cytoplasm leads to a loss of axis information. The yellow cytoplasm specifies the anterior/posterior axis. When the yellow cytoplasm moves to the posterior of the egg to become posterior vegetal cytoplasm (PVC), the anterior/posterior axis is specified.
The posterior inferior iliac spine is an anatomical landmark that describes a bony "spine", or projection, at the posterior and inferior surface of the iliac bone. It is one of two such spines on the posterior surface, the other being the posterior superior iliac spine. These two spines are separated by a bony notch. They appear as two dimples in the skin, at the level of the lower back.

It correlates with a large posterior temporal bulge. Curtin described five varieties, based on size, shape, and change in appearance of the optic nerve and retinal vessels, but the posterior pole type is the most common.Curtin, B.J., The posterior staphyloma of pathologic myopia. Trans Am Ophthalmol Soc, 1977.
The anterior cingulate is connected to the posterior cingulate at least in rabbits. Posterior cingulate gyrus is connected with retrosplenial cortex and this connection is part of the dorsal splenium of the corpus callosum. The anterior and posterior cingulate gyrus and retrosplenial cortex send projections to subiculum and presubiculum.
In nine out of ten people with tone deafness, the superior arcuate fasciculus in the right hemisphere could not be detected, suggesting a disconnection between the posterior superior temporal gyrus and the posterior inferior frontal gyrus. Researchers suggested the posterior superior temporal gyrus was the origin of the disorder.
Opisthoglyphous colubrids have enlarged, grooved teeth situated at the posterior extremity of the maxilla, where a small posterior portion of the upper labial or salivary gland produces venom.
Many annelids possess the capability to regenerate their anterior, posterior, or both ends of their body. C. teleta is capable of posterior regeneration. Both juveniles and adults can regenerate their posterior halves quite well. A staging system has been established, describing the sequential regeneration events in juveniles of C. teleta.
The aperture rather large, strongly channeled anteriorly and posteriorly. The posterior sinus is deeply notched and immediately below the summit. There is a slender stromboid notch a little posterior to the anterior termination of the outer lip. The space between this and the posterior sinus is protracted into a clawlike element.

A posterior capsular opacity (PCO) around a posterior chamber IOL (as seen on retroillumination in a slit lamp). Posterior capsule opacification (PCO), often referred to as "after cataract", is the most common complication of cataract surgery. In a small percentage of patients, posterior chamber intraocular lenses may form PCOs a few months after implantation. They are easily treatable, and typically only require a one-time capsulotomy procedure (using a Nd:YAG laser) to clarify.
Blood supply to the brain is normally divided into anterior and posterior segments, relating to the different arteries that supply the brain. The two main pairs of arteries are the Internal carotid arteries (supply the anterior brain) and vertebral arteries (supplying the brainstem and posterior brain). The anterior and posterior cerebral circulations are interconnected via bilateral posterior communicating arteries. They are part of the Circle of Willis, which provides backup circulation to the brain.
Its amphids are outlined; its oesophagus forms about 9–14% of its body length, and is slightly inflated at its anterior end; its posterior part (oesophagus) is overlapped by a large oesophageal gland with a substantial cell nucleus in the middle. Its excretory pore is located posterior to its nerve ring. Its testis slightly exceeds anteriorly the posterior end of the oesophagus. The posterior end of its body counts with two lateral U-shaped mounds.
Within the vertebrate eye, there are considered to be three chambers: anterior, posterior, and vitreous. It is important to note that the eye can also be classified as having two cavities: anterior and posterior. Both the anterior and posterior chambers are located within the anterior cavity, while the vitreous chamber is located in the posterior cavity. The best way to distinguish between the two cavities is to use the lens as a dividing point.
The females have a bluntly round posterior end compared to their male counterparts with a coiled posterior end. Their characteristic eggs are barrel-shaped and brown, and have bipolar protuberances.
In posterior rhinoscopy, the endoscope is advanced through the mouth to examine the back of the nasal cavity above the soft palate, and can be used to visualise the oropharynx below that. structures seen in posterior Rhinoscopy -posterior border of nasal septum, fossa of roosenmuller, eustachian tube opening, upper surface of soft palate.
The circumflex artery curves to the left around the heart within the coronary sulcus, giving rise to one or more left marginal arteries (also called obtuse marginal branches (OM)) as it curves toward the posterior surface of the heart. It helps form the posterior left ventricular branch or posterolateral artery. The circumflex artery ends at the point where it joins to form to the posterior interventricular artery in 15% of all cases, which lies in the posterior interventricular sulcus. In the other 85% of all cases the posterior interventricular artery comes out of the right coronary artery.
Posterior horn shown in red. The posterior horn of lateral ventricle, or occipital horn, impinges into the occipital lobe in a posterior direction, initially laterally but subsequently curving medially and lilting inferiorly on the lateral side. The tapetum of the Corpus Callosum continues to form the roof, which due to the lilt is also the lateral edge. However, the posterior and anterior ends of the Corpus Callosum are characterised by tighter bundling, known as forceps (due to the resulting shape), to curve around the central sulci; the edge of these forceps form the upper part of the medial side of the posterior horn.
Anconeus originates on the posterior surface of the lateral epicondyle of the humerus and inserts distally on the superior posterior surface of the ulna and the lateral aspect of the olecranon.

The anterior ethmoidal artery, is a branch of the ophthalmic artery in the orbit. It exits the orbit through the anterior ethmoidal foramen. The posterior ethmoidal artery is posterior to it.
HOXD9 and HOXD10 are expressed in the developing limb throughout the entire anterior-posterior axis, followed by HOXD11, HOXD12, HOXD13, which are each expressed in more posterior regions, with HOXD13 being restricted to only the most posterior regions of the limb bud. As a result, HOXD expression clusters around the posterior ZPA (where HOXD9, 10, 11, 12, and 13 are all expressed), while less expression occurs around the AER, where only HOXD9 and HOXD10 are expressed.
As well as being a key muscle and tendon for stabilization, the tibialis posterior also contracts to produce inversion and assists in the plantar flexion of the foot at the ankle. The tibialis posterior has a major role in supporting the medial arch of the foot. Dysfunction of the tibialis posterior, including rupture of the tibialis posterior tendon, can lead to flat feet in adults, as well as a valgus deformity due to unopposed eversion when inversion is lost.
The anterior and posterior petroclinoid ligaments are bands composed of collagen and elastic fibres that are densely packed in fascicles Their function: The anterior petroclinoid ligament acts to laterally limit the superior wall of the cavernous sinus. The posterior petroclinoid ligament limits the posterior wall of the cavernous sinus. The angle between the two ligaments varies from 20 to 55 degrees. Anatomical Relations and Clinical significance: The posterior petroclinoid ligament is in close proximity to the oculomotor nerve.
The Posterior Bronchial Branches (rami bronchiales posteriores; posterior or dorsal pulmonary branches), more numerous and larger than the anterior, are distributed on the posterior surface of the root of the lung; they are joined by filaments from the third and fourth (sometimes also from the first and second) thoracic ganglia of the sympathetic trunk, and form the posterior pulmonary plexus. Branches from this plexus accompany the ramifications of the bronchi through the substance of the lung.
The posterior end lifts out of the water and forms a right angle. It is then exposed to air and is used to exchange oxygen and carbon dioxide, although this exposes its posterior to its enemies. If the photo-receptors detect a shadow or movement, the posterior rapidly shortens in response to a threat.
The calf is composed of the muscles of the posterior compartment of the leg: The gastrocnemius and soleus (composing the triceps surae muscle) and the tibialis posterior. The sural nerve provides innervation.
It extends throughout the entire length of the medulla spinalis, and on transverse section appears as an oval area in front of the posterior column and medial to the posterior spinocerebellar tract.
The posterior border may be more or less closely united to the piriformis, or some of the fibers end on its tendon. The posterior fibres of gluteus medius contract to produce hip extension, lateral rotation and abduction. During gait, the posterior fibres help to decelerate internal rotation of the femur at the end of swing phase.

The Posterior Rhine rises in the Rheinwald below the Rheinwaldhorn.
The posterior scrotal branches (in men) or posterior labial branches (in women) are two in number, medial and lateral. They are branches of the perineal nerve, which is itself a branch of the pudendal nerve. The pudendal nerve arises from spinal roots S2 through S4, travels through the pudendal canal on the fascia of the obturator internus muscle, and gives off the perineal nerve in the perineum. The major branch of the perineal nerve is the posterior scrotal/posterior labial.
The posterior insula projects predominantly to the dorsal aspect of the lateral and to the central amygdaloid nuclei. In contrast, the anterior insula projects to the anterior amygdaloid area as well as the medial, the cortical, the accessory basal magnocellular, the medial basal, and the lateral amygdaloid nuclei. The posterior part of the insula is formed by a long gyrus. The posterior insula connects reciprocally with the secondary somatosensory cortex and receives input from spinothalamically activated ventral posterior inferior thalamic nuclei.
Engrailed mutant clones of posterior origin will gain anterior affinity and move towards the anterior compartment and intermix with those cells. Within the posterior compartment these clones will sort out and form an ectopicborder where they meet other posterior cells. Similarly, a clone of anterior cells expressing engrailed will gain posterior identity and create an ectopic boundary where the clone meets other anterior cells in this compartment. In addition, to its cell autonomous role in specifying posterior compartment identity, engrailed also has a non-cell autonomous function in the general growth and patterning of the wing disc, through the activation of signaling pathways such as Hedgehog (Hh) and Decapentaplegic (Dpp).
The function of the posterior cruciate ligament (PCL) is to prevent the femur from sliding off the anterior edge of the tibia and to prevent the tibia from displacing posterior to the femur. Common causes of PCL injuries are direct blows to the flexed knee, such as the knee hitting the dashboard in a car accident or falling hard on the knee, both instances displacing the tibia posterior to the femur. Surgery to repair the posterior cruciate ligament is controversial due to its placement and technical difficulty. The posterior drawer test is one of the tests used by doctors and physiotherapists to detect injury to the PCL.
The buccal surface of each post- canine is smooth. The teeth are also slightly angled so that the posterior of one tooth contacts the anterior of the next. The posterior accessory cusps of teeth 2 and 3 curve upwards towards the top of the tooth. The 4th tooth shows posterior accessory cusps as well as at least one cusp mesial to the main cusp. The 5th tooth only shows one posterior accessory cusp, but the lack of other accessory cusps is “probably due to wear.” The 6th tooth on to the 9th tooth have multiple posterior accessory cusps as well as at least one mesial cusp.
The flexor digitorum longus runs along the medial posterior side of the lower leg and aids in flexions of the toes (apart from the big toe). It arises from the posterior surface of the body of the tibia, from immediately below the soleal line to within 7 or 8 cm of its lower extremity, medial to the tibial origin of the Tibialis posterior; it also arises from the fascia covering the Tibialis posterior. The fibers end in a tendon, which runs nearly the whole length of the posterior surface of the muscle. This tendon passes behind the medial malleolus, in a groove, common to it and the tibialis posterior, but separated from the latter by a fibrous septum, each tendon being contained in a special compartment lined by a separate mucous sheath.
Zuckerkandl's fascia or fascia retrorenalis is a fibrous sheath covering the posterior side of the kidney. It constitutes the posterior layer of the renal fascia and was first described by Emil Zuckerkandl in 1883.
The origin of this artery is proximal to the origin of medial and lateral posterior choroidal branch of the posterior cerebral artery. The main collicular artery also gives branch to an accessory collicular artery.

The posterior intermuscular septum of leg, or posterior crural intermuscular septum is a band of fascia which separates the lateral compartment of leg. The deep fascia of leg gives off from its deep surface, on the lateral side of the leg, two strong intermuscular septa, the anterior and posterior peroneal septa, which enclose the Peronæi longus and brevis, and separate them from the muscles of the anterior and posterior crural regions, and several more slender processes which enclose the individual muscles in each region.
The posterior cortex is the “sensory” cortex, much as the frontal cortex is the “action” cortex. The posterior cortex is responsible for encoding the sensory content (visual, auditory, and tactile) of any experience (both real and imaginary experience). The posterior cortex with the exception of the primary sensory areas (Primary visual cortex (V1), primary auditory cortex, and somatosensory cortex) was called by Christof Koch and colleagues the posterior cortical hot zone for its close association with the minimal neural substrate essential for conscious perception.
In anatomy, there are two posterior tibial veins of the lower limb. They receive blood from the medial and lateral plantar veins and drain the posterior compartment of the leg and the plantar surface of the foot to the popliteal vein which it forms when it joins with the anterior tibial vein. Like most deep veins, posterior tibial veins are accompanied by an homonym artery, the posterior tibial artery, along its course. They receive the most important perforator veins: the Cockett perforators, superior, medial and inferior.
Cortical bone is known to resorb slower than the medullary bone. Therefore, cortical anchorage is used in orthodontics to allow for slower movement of teeth, especially molars in the posterior dentition. A clinician may produce a movement which allows the buccal roots of the permanent molars to move buccally (outside), eventually contacting the cortical bone. It is claimed that by using cortical bone against posterior teeth, mesial movement of posterior teeth can be prevented which helps in anchoring the posterior teeth in the back of the jaw.
It supplies motor innervation to iliopsoas, pectineus, sartorius, and quadriceps; and sensory branches to the anterior thigh, medial lower leg, and posterior foot. The nerves of the sacral plexus pass behind the hip joint to innervate the posterior part of the thigh, most of the lower leg, and the foot. The superior (L4-S1) and inferior gluteal nerves (L5-S2) innervate the gluteus muscles and the tensor fasciae latae. The posterior femoral cutaneous nerve (S1-S3) contributes sensory branches to the skin on the posterior thigh.
Climacostomum virens The body is somewhat flexible but non-contractile, roughly ovoid or harp- shaped, and flattened from back to front. It has a large posterior contractile vacuole, and a characteristic posterior indentation (more pronounced in underfed individuals). The posterior vacuole surrounds the cytoproct (anus), through which food waste is eliminated. The macronucleus of Climacostomum virens is normally long and wormlike (vermiform).
The posterior processes of the pterygoids are curved inward to join the quadrate. The posterior pterygoid process extends upward in a thin plate, including a large infra-temporal vacuity. The length of each interpterygoid vacuity is approximately three times greater than its width, or equal to about a third of the skull length. The interpterygoid vacuities set back in posterior half of skull.

The posterior surface of forearm, ventral half of flank, anterior and posterior surface of thigh, posterior surface of shank, and dorsal surface of foot are black with distinct, vermiform, bright yellow markings. The upper lip stripe is yellow while the lower lip is black. The belly is white.
The posterior auricular vein begins upon the side of the head, in a plexus which communicates with the tributaries of the occipital vein and superficial temporal veins. It descends behind the auricula, and joins the posterior division of the posterior facial vein to form the external jugular vein. It receive the stylomastoid vein, and some tributaries from the cranial surface of the auricula.
Lumbar plexus and branches The lumbar nerves are the five spinal nerves emerging from the lumbar vertebrae. They are divided into posterior and anterior divisions. Posterior divisions: The medial branches of the posterior divisions of the lumbar nerves run close to the articular processes of the vertebrae and end in the multifidus muscle. The laterals supply the erector spinae muscles.
Megalodiscus temperatus are flukes that contain a pair of posterior fluid filled pouch located in the oral sucker with a posterior sucker that is equal to the largest width of the body. The tegumental surface of this parasite contains various rows of indentations. The patterns of the indentation merge into several areas into folds with ridges that represent the posterior and genital pores.
1) the lobes are notably longer than the posterior sections. Basal glabellar width in hicksii is notably narrower (tr.) than each posterior cranidial border (tr.), in contrast to basal glabellar width in the Czech species which is clearly greater (tr.) than the posterior fixigenal width. In terms of comparative dimensions the Czech species is more akin to Plutonides? Illingi Lake (1935, p.

Similarly, expression is restricted to the posterior trunk of chicken embryos. In Zebrafish embryos expression of miR-10 is also restricted to the posterior trunk, later in development it is further restricted to the spinal cord.
Vitellaria lateral. Genital pore just anterior to the ventral sucker, usually somewhat to the left of the median line. Cirrus sac extends behind the acetabulum. Ovary posterior to or at the posterior level of cirrus sac.
The posterior pituitary consists mainly of neuronal projections (axons) of magnocellular neurosecretory cells extending from the supraoptic and paraventricular nuclei of the hypothalamus. These axons store and release neurohypophysial hormones oxytocin and vasopressin into the neurohypophyseal capillaries, from there they get into the systemic circulation (and partly back into the hypophyseal portal system). In addition to axons, the posterior pituitary also contains pituicytes, specialized glial cells resembling astrocytes assisting in the storage and release of the hormones. Classification of the posterior pituitary varies, but most sources include the two regions below: ;Pars nervosa: Also called the neural lobe or posterior lobe, this region constitutes the majority of the posterior pituitary and is the storage site of oxytocin and vasopressin.
In Bayesian statistics, the posterior probability of a random event or an uncertain proposition is the conditional probability that is assigned after the relevant evidence or background is taken into account. "Posterior", in this context, means after taking into account the relevant evidence related to the particular case being examined. For instance, there is a ("non-posterior") probability of a person finding buried treasure if they dig in a random spot, and a posterior probability of finding buried treasure if they dig in a spot where their metal detector rings. Similarly, the posterior probability distribution is the probability distribution of an unknown quantity, treated as a random variable, conditional on the evidence obtained from an experiment or survey.
Gracey curettes have sharp cutting edges on only one side of their blades. There are two site-specific Gracey curettes -- posterior mesial (white ring) and posterior distal (blue ring), in addition to the anterior curette (red ring).
It sweeps around the posterior border of the deltoideus and supplies the skin over the lower two-thirds of the posterior part of this muscle, as well as that covering the long head of the triceps brachii.
Lymphatic channels from the posterior half of the scalp drain to occipital and posterior auricular nodes. Lymphatic channels from the anterior half drain to the parotid nodes. The lymph eventually reaches the submandibular and deep cervical nodes.
The anterior spinal cord is at increased risk for infarction because it is supplied by the single anterior spinal artery, which has few collateral unlike the posterior spinal cord which is supplied by two posterior spinal arteries.
The inner lip is calloused, showing transverse plicae. The anterior and posterior canals are well developed. The siphonal canal at the anterior end is usually short. The anal canal at the posterior end is a deep slot.

The inferior posterior unciform facet is widely separated from the anterior one.
The posterior pituitary (or neurohypophysis) is the posterior lobe of the pituitary gland which is part of the endocrine system. The posterior pituitary is not glandular as is the anterior pituitary. Instead, it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary, and serve as a site for the secretion of neurohypophysial hormones (oxytocin and vasopressin) directly into the blood. The hypothalamic–neurohypophyseal system is composed of the hypothalamus (the paraventricular nucleus and supraoptic nucleus), posterior pituitary, and these axonal projections.
All successive isomers are similar to it, but gradually decrease in size and in angle of inclination from the anterior part (head) of the body to the posterior end. New isomers were added at the growth point at the posterior end of the proarticulate body. With age, the addition of new isomers slowed down and probably stopped, the growth point shifted from the posterior end, and the relative length of the posterior isomers increased, sometimes significantly. The overall number of body isomers amounts from several pairs (Vendia, Onega) to several hundreds (Dickinsonia).

In adults, the distance between the anterior and posterior walls (sulcal span) increases, while the surface area of walls, the sulcal length of the posterior wall, and the convolution (fractal dimension) for the right posterior wall of the central sulcus decrease. The posterior walls of the central sulcus appear to be affected more with age. Differences between genders regarding the average width of the central sulcus as one ages has also been shown. The average width of the central sulcus in males tends to increase more rapidly over time than that of females.
The genus differs from most colubrid genera in lacking hypapophyses on posterior dorsal vertebrae and in bearing nine maxillary teeth (the posterior-most teeth are subequal) and nine palatine teeth. Dorsal scale reduction is characterized by vertebral reductions, increase of scale rows posterior to neck, a single lateral reduction at midbody, and regular vertebral reductions in posterior half of the body. The rostral scale is not visible from above; a small presubocular scale is present. There are eight supralabials, the fourth and fifth ones are in contact with the orbit.
The middle third of the posterior surface is divided by a vertical ridge into two parts; the ridge begins at the popliteal line and is well- marked above, but indistinct below; the medial and broader portion gives origin to the Flexor digitorum longus, the lateral and narrower to part of the Tibialis posterior. The remaining part of the posterior surface is smooth and covered by the Tibialis posterior, Flexor digitorum longus, and Flexor hallucis longus. Immediately below the popliteal line is the nutrient foramen, which is large and directed obliquely downward.

As the supplying component of the vertebrobasilar vascular system, the vertebral arteries supply blood to the upper spinal cord, brainstem, cerebellum, and posterior part of brain. A stroke of the arteries may result in a posterior circulation stroke.
The forewings are brown, with the posterior half dark fuscous. There is a moderate evenly broad direct white fascia at two-thirds, with the anterior edge straight and the posterior irregular. The hindwings are grey.Meyrick, Edward (1916–1923).
The maxillary vein and the superficial temporal vein later join to become the retromandibular vein. The posterior branch of the retromandibular vein and posterior auricular vein then form the external jugular vein, which empties into the subclavian vein.
The premedian plate is thickens as you move posterior. The posterior wall of the premedian plate concaves to form the anterior wall of the orbito-nasal cavity and shows prerostral process. The pineal plate is small, trapezoidal, thin bone that covers the most posterior part of the orbito-nasal cavity. It has a rough ornamented surface and a smooth visceral surface that has a round pineal pit.
They can also be found in the ventral horn neurons and in the cholinergic laterodorsal tegmentum (LDT) and pedunculopontine tegmentum (PPT) nuclei. A comparison of peripherin expression in the posterior and lateral hypothalamus in mice showed a sixty-fold higher expression in the posterior hypothalamus. This higher expression is due to the presence of peripherin in the tuberomammillary neurons of the mouse posterior hypothalamus.
The posterior cerebral artery (PCA) is one of a pair of arteries that supply oxygenated blood to the occipital lobe, part of the back of the human brain. The two arteries originate from the distal end of the basilar artery, where it bifurcates into the left and right posterior cerebral arteries. These anastomose with the middle cerebral arteries and internal carotid arteries via the posterior communicating arteries.
Lantana, and on members of the families Cannabaceae, Oleaceae, Pedaliaceae and others. The larvae are stout with a posterior horn, as is typical of larvae of the Sphingidae. Most sphingid larvae however, have fairly smooth posterior horns, possibly with a simple curve, either upward or downward. In contrast, Acherontia species and certain relatives bear a posterior horn embossed with round projections about the thicker part.
The cingulate gyrus plays a key role in the limbic system's emotion formation and processing. The cingulate cortex is separated into an anterior and a posterior region, which corresponds to areas 24, 32, 33 (anterior) and 23 (posterior) of the Brodmann areas. The anterior region receives information mainly from the mamillary bodies while the posterior cingulate receives information from the subiculum via the Papez circuit.
Apart from the sensory and head cilia mentioned above, the ventral ciliation is continuous and dense, extending from the posterior edge of the mouth to the two-thirds of the pharynx. Then, the ciliary field separates in two bands running until the posterior part of the body. The very anterior part of the ciliary continuous dorsal field is wider than the more posterior part.
Many studies have suggested that the posterior superior temporal sulcus is associated the crossmodal binding of auditory and visual stimuli. The activation of this posterior portion of the superior temporal sulcus was reported in the detection of audio-visual incongruences and in voice perception. The posterior superior temporal sulcus has also been shown to be preferentially activated by lip reading.Uno T, Kawai K, Sakai K, et al.
Larvae of some species have ciliated patches. Those of Multicotyle purvisi have four patches on the anterior side of the posterior sucker and six at the posterior side, those of Cotylogaster occidentalis have an anterior ring of eight and a posterior ring of six, while larvae of Aspidogaster conchicola, Lobatostoma manteri, Rugogaster hydrolagi lack cilia altogether. Larvae of some species hatch from eggs, others do not.
Posterior urethral valve (PUV) disorder is an obstructive developmental anomaly in the urethra and genitourinary system of male newborns. A posterior urethral valve is an obstructing membrane in the posterior male urethra as a result of abnormal in utero development. It is the most common cause of bladder outlet obstruction in male newborns. The disorder varies in degree, with mild cases presenting late due to milder symptoms.
The axillary nerve or the circumflex nerve is a nerve of the human body, that originates from the brachial plexus (upper trunk, posterior division, posterior cord) at the level of the axilla (armpit) and carries nerve fibers from C5 and C6. The axillary nerve travels through the quadrangular space with the posterior circumflex humeral artery and vein to innervate the deltoid and teres minor.
Transactions and Proceedings of the Royal Society of New Zealand. 84: 297-307. The axostyle is a single, contractible appendage made of microtubules that originates from the posterior end of the preaxostyle, and is situated near the posterior pair of the basal bodies (known as blepharoplast in older cytological literature). The cytoskeleton is based around four basal bodies, an anterior pair and a posterior pair.
PION is less common than Anterior Ischemic Optic Neuropathy (AION). Blood supply and surrounding anatomy make the anterior and posterior portions of the optic nerve susceptible to different ischemic pressures. The posterior optic nerve receives blood primarily from the pial branches of the ophthalmic artery. The optic canal, a boney tunnel leading to the brain, surrounds the most posterior part of this optic nerve segment.
The posterior interventricular sulcus or posterior longitudinal sulcus is one of the two grooves that separates the ventricles of the heart and is on the diaphragmatic surface of the heart near the right margin. The other groove is the anterior interventricular sulcus, situated on the sternocostal surface of the heart, close to its left margin. In it runs the posterior interventricular artery and middle cardiac vein.
Only one muscle is attached to the cuboid bone; the tibialis posterior. The tibialis posterior inserts to the under surface of the cuboid bone. While the flexor hallucis brevis arises, by a pointed tendinous process, from the medial part of the under surface of the cuboid bone, from the contiguous portion of the lateral cuneiform bone, and from the prolongation of the tendon of the tibialis posterior.
The subcostal vein is a vein in the human body that runs along the bottom of the twelfth rib. It has the same essential qualities as the posterior intercostal veins, except that it cannot be considered intercostal because it is not between two ribs. Each subcostal vein gives off a posterior (dorsal) branch which has a similar distribution to the posterior ramus of an intercostal artery.

Median sagittal section through the occipital bone and first three cervical vertebræ, showing ligamentous attachments The posterior arch forms about two-fifths of the circumference of the ring: it ends behind in the posterior tubercle, which is the rudiment of a spinous process and gives origin to the Recti capitis posteriores minores and the ligamentum nuchae. The diminutive size of this process prevents any interference with the movements between the atlas and the skull. The posterior part of the arch presents above and behind a rounded edge for the attachment of the posterior atlantooccipital membrane, while immediately behind each superior articular process is the superior vertebral notch (sulcus arteriae vertebralis). This is a groove that is sometimes converted into a foramen by ossification of the posterior atlantooccipital membrane to create a delicate bony spiculum which arches backward from the posterior end of the superior articular process.
A diagnosis can be made following injections into the posterior sacroiliac transverse ligament.

The cercaria has two suckers: a ventral sucker and rounded subterminal sucker. Intestinal ceca bifurcate posterior to pharynx. Excretory bladders are located at posterior end of the cercarial body. The metacercarial cyst is elongated and oval-shaped with sensory papillae.
As for the associating microfibrillar bundle, it is a collection of microfilaments that links the kinetosomes (at the lamellae near the posterior kinetosomes) to the region of the posterior end of the ribbon. The bundle of microfilaments is located on the concave side of the right (posterior) ribbon, which resembles the string on a harp. The mastigote system is fully described in the research of the type species.
The size of the transverse processes indicate that these are most likely posterior dorsal vertebrae. A pair of small excavations are present dorsally on the neural arch, between and slightly posterior to the prezygapophyses. There is no evidence of ventral excavation of the centra for intercentra, a common feature of caseid posterior dorsal vertebrae. Thus, the morphology of the centra and neural arches are entirely in agreement with known caseid morphology.
Other posterior proteins, oskar (which tethers nanos mRNA), Tudor, vasa, and Valois, localize the germ line determinants and nanos to the posterior. In contrast to the anterior and the posterior, the positional information for the terminalia come from the follicle cells of the ovary. The terminalia are specified through the action of the Torso receptor tyrosine kinase. The follicle cells secrete Torso-like into the perivitelline space only at the poles.
The aortic valve normally has three cusps however there is some discrepancy in their naming. They may be called the left coronary, right coronary and non-coronary cusp. Some sources also advocate they be named as a left, right and posterior cusp. – "Heart: The Aortic Valve and Aortic Sinuses" Anatomists have traditionally named them the left posterior (origin of left coronary), anterior (origin of the right coronary) and right posterior.
The blood supply of these plexuses is from the posterior inferior cerebellar artery. The lateral ventricles also contains the right and left internal cerebral veins (which drain the choroid plexuses) at its roof (the two veins unite to form the great cerebral vein). The arteries carrying blood into the choroid plexuses are: # the anterior choroidal artery (branch from the internal carotid). # the posterior choroidal artery (branch from the posterior cerebral artery).
Posterior drawer test and tibial sag tests can determine the integrity of the posterior cruciate ligament. Similar to anterior drawer test, the knee should be flexed 90 degrees and the tibia is pushed backwards. If the tibia can be pushed posteriorly, then the posterior drawer test is positive. In tibial sag test, both knees are flexed at 90 degrees with the person in supine position and bilateral feet touching the bed.

Its anterior end, thin and pointed, is attached to the anterior intercondyloid fossa of the tibia, in front of the anterior cruciate ligament; Its posterior end is fixed to the posterior intercondyloid fossa of the tibia, between the attachments of the lateral meniscus and the posterior cruciate ligament. It is fused with the tibial collateral ligament which makes it far less mobile than the lateral meniscus. The points of attachment are relatively widely separated and, because the meniscus is wider posteriorly than anteriorly, the anterior crus is considerably thinner than the posterior crus.
Branches of the ophthalmic artery – the anterior and posterior ethmoidal arteries supply the roof, upper bony septum, and ethmoidal and frontal sinuses. The anterior ethmoidal artery also helps to supply the lower septal cartilage. Another branch is the dorsal nasal artery a terminal branch that supplies the skin of the alae and dorsum. Branches of the maxillary artery include the greater palatine artery; the sphenopalatine artery and its branches – the posterior lateral nasal arteries and posterior septal nasal branches; the pharyngeal branch; and the infraorbital artery and its branches – the superior anterior and posterior alveolar arteries.
The anterior/posterior axis is defined during the initial tilting of the embryo when the eggshell is being desposited. The egg is constantly being rotated in a consistent direction and there is a partial stratification of the yolk; the lighter yolk components will be near one end of the blastoderm and will become the future posterior. The molecular basis of the posterior is not known, however, the accumulation of cells eventually results in the posterior marginal zone (PMZ). The PMZ is the equivalent of the Nieuwkoop center is that its role is to induce Hensen's node.
When using a conjugate prior, the posterior distribution will be from the same family, but will have different hyperparameters, which reflect the added information from the data: in subjective terms, one's beliefs have been updated. For a general prior distribution, this is computationally very involved, and the posterior may have an unusual or hard to describe form, but with a conjugate prior, there is generally a simple formula relating the values of the hyperparameters of the posterior to the values of the hyperparameters of the prior, and thus the computation of the posterior distribution is very easy.
Posterior cord syndrome, in which just the dorsal columns of the spinal cord are affected, is usually seen in cases of chronic myelopathy but can also occur with infarction of the posterior spinal artery. This rare syndrome causes the loss of proprioception and sense of vibration below the level of injury while motor function and sensation of pain, temperature, and touch remain intact. Usually posterior cord injuries result from insults like disease or vitamin deficiency rather than trauma. Tabes dorsalis, due to injury to the posterior part of the spinal cord caused by syphilis, results in loss of touch and proprioceptive sensation.
Considerable anatomic variation exists in the circle of Willis. Based on a study of 1413 brains, the classic anatomy of the circle is only seen in 34.5% of cases. In one common variation the proximal part of the posterior cerebral artery is narrow and its ipsilateral posterior communicating artery is large, so the internal carotid artery supplies the posterior cerebrum; this is known as a fetal posterior communicating cerebral artery. In another variation the anterior communicating artery is a large vessel, such that a single internal carotid supplies both anterior cerebral arteries; this is known as an azygos anterior cerebral artery.
Mutually protected occlusion - Posterior disocclusion of teeth as the mandible is protruded (Institute of Dentistry Aberdeen University) The Journal of Prosthetic Dentistry (2017) defines mutually protected occlusion as ‘an occlusal scheme in which the posterior teeth prevent excessive contact of the anterior teeth in maximal intercuspal position, and the anterior teeth disengage the posterior teeth in all mandibular excursive movements’ In eccentric movements, damaging forces are applied to the posterior teeth and the anteriors are best suited to receiving these. Therefore during protrusive movements, the contact or guidance of the anteriors should be adequate to disocclude and protect the posterior teeth. In contrast, the posterior teeth are more suited to accept the forces that are applied during closure of the mandible. This is because the posteriors are positioned so the forces are applied directly along the long axis of the tooth and are able to dissipate them efficiently whereas the anteriors cannot accept these heavy forces as well due to their labial positioning and angulation.
The thorax tipped behind with a V-shaped white mark. The first two segments of the abdomen have some black on the posterior margin, followed by white on the following segment. The remainder has white posterior margins. A lateral white line is present.
The abductor pollicis longus muscle is innervated by the posterior interosseous nerve, which is a continuation of the deep branch of the radial nerve after it passes through the supinator muscle. The posterior interosseous nerve is derived from spinal segments C7 & C8.

The petroclinoid ligament is a fold of dura mater. It extends between the posterior clinoid process and anterior clinoid process and the petrosal part of the temporal bone of the skull. See posterior clinoid process page for full information on this ligament.
This type of anchorage is considered moderate, which involves 50% movement of both anterior and posterior teeth into the extraction space. The expectation in this type of anchorage is to see posterior teeth moving forward equally as compared to anterior teeth moving backwards.
Despite its name, the extensor carpi ulnaris is innervated by the posterior interosseous nerve (C7 and C8), the continuation of the deep branch of the radial nerve. It would therefore be paralyzed in an injury to the posterior cord of the brachial plexus.

The posterior surface of this forms a steeply inclined trough running from the suture to the distal extremity of the paraoccipital process. The ventral margin of this trough is formed by a narrow ridge which also divides the posterior and anterior surfaces of the bone. There is another ridge dividing the dorsal third of the bone from this posterior surface. The anterior surface is concave and widens towards the contact with the prootic.
It is sometimes visible on careful examination but usually more easily through an ophthalmoscope or slit-lamp. Anterior synechia causes closed angle glaucoma, which means that the iris closes the drainage way of aqueous humour which in turn raises the intraocular pressure. Posterior synechia also cause glaucoma, but with a different mechanism. In posterior synechia, the iris adheres to the lens, blocking the flow of aqueous humor from the posterior chamber to the anterior chamber.
The flexor hallucis longus muscle (FHL) is one of the three deep muscles of the posterior compartment of the leg that attaches to the plantar surface of the distal phalanx of the great toe. The other deep muscles are the flexor digitorum longus and tibialis posterior; the tibialis posterior is the most powerful of these deep muscles. All three muscles are innervated by the tibial nerve which comprises half of the sciatic nerve.
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.
In mammals, the primitive streak and other surrounding tissues produce the morphogenic compounds Wnts, BMPs, FGFs, Nodal and retinoic acid to establish the posterior region during late gastrula. These proteins form concentration gradients. Areas of highest concentration establish the posterior region while areas of lowest concentration indicate the anterior region. In fish and frogs, β-catenin produced by canonical Wnt signaling causes the formation of organizing centers, which, alongside BMPs, elicit posterior formation.
Its anterior parapodia count with about 9–10 compound chaetae, exhibiting dorsoventral gradation in length, being 26µm above and 12–13 µm below. The number of posterior compound chaetae declines to a number of 5–6 on the posterior parapodia. Salvatoria koorineclavata shows ventral simple chaetae on the majority of posterior parapodia of some specimens. Its anterior parapodia possess 2 aciculae each, one straight and one acuminate, while simultaneously showing solitary acicula in its midbody.
Climacostomum virens, from Alfred Kahl, 1932 Climacostomum virens has a flexible but non-contractile body, long, roughly ovoid or harp- shaped, and flattened from back to front. It has a large posterior contractile vacuole, and a characteristic posterior indentation, or dimple, that is more pronounced in underfed individuals. The posterior vacuole surrounds the cytoproct (anus), through which food waste is eliminated. The macronucleus of Climacostomum virens is normally long and wormlike (vermiform).
Similarly, the posterior cells of Koller's sickle form the posterior region of the primitive streak. This differential movement is due to expression of different mesodermal marker genes among the cells located in different areas of Koller's sickle. Chordin is expressed in cells of the anterior streak, while Wnt8c is expressed in cells of the posterior streak. The movement is coordinated by a Wnt signaling pathway which is activated by fibroblast growth factors from the hypoblast.

Dpp is produced in a stripe just anterior of the anterior/posterior border and diffuses out to the edges of the tissue.In the fly wing, the posterior and anterior halves of the tissue are populated by different kinds of cells that express different genes. Cells in the posterior but not the anterior express the transcription factor Engrailed (En).
The petroclinoid ligament is a fold of dura matter. It extends between the posterior clinoid process and anterior clinoid process and the petrosal part of the temporal bone of the skull. There are two separate bands of the ligament; named the anterior and posterior petroclinoid ligaments respectively. The anterior petroclinoid ligament is considered to be an extension of the tentorium cerebelli and the posterior petroclinoid ligament arises from the posteromedial extensions of the tentorial notch.
The new right-sided hemorrhage was centered on the posterior putamen with surrounding edema involving the posterior portion of the posterior limbs of the internal, external, and extreme capsules. Signal abnormalities extended into the right temporal lobe. The patient had no other neurologic deficits and spoke fluently, although with poor internal volume control of her voice. Otoscopic examination revealed normal-appearing external auditory canals, intact tympanic membranes bilaterally, and normal middle ear anatomy.
The posterior lobe develops as an extension of the hypothalamus, from the floor of the third ventricle. The posterior pituitary hormones are synthesized by cell bodies in the hypothalamus. The magnocellular neurosecretory cells, of the supraoptic and paraventricular nuclei located in the hypothalamus, project axons down the infundibulum to terminals in the posterior pituitary. This simple arrangement differs sharply from that of the adjacent anterior pituitary, which does not develop from the hypothalamus.
The acronematic posterior flagellum is trailed and sometimes forms an undulating membrane. It is typically directed straight behind the cell and is about 2 to 4 times the length of the cell. The proximal part of the posterior flagellum is accompanied with a paraxial rod and sometimes non- tubular mastigonemes. The cells use their posterior flagellum and rotate around their longitudinal axes to swim and glide along in rapid darts of straight lines.
The teeth are blunt with the dental formula . A characteristic yellowish-brown strip is formed on the dorsal side between the snout and the posterior tip. On the lateral side, a black strip runs from the anterior to the posterior side of the body. Within a week of metamorphosis, small bronzed-coloured strips appear on either sides of the lower jaw, between the snout and the posterior point of the fore limbs.
In Cnidaria larvae, neurons are not distributed homogenously along the anterior-posterior axis; Cnidaria demonstrate anatomical polarities during the differentiation of a nervous system. There are two main hypotheses that attempt to explain neuronal cell differentiation. The zootype hypothesis says that regulatory genes define an anterior-posterior axis and the urbilateria hypothesis says that genes specify a dorsal-ventral axis. Experiments suggest that developmental neurogenesis is controlled along the anterior-posterior axis.
Intracranial aneurysm, also known as brain aneurysm, is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel. Aneurysms in the posterior circulation (basilar artery, vertebral arteries and posterior communicating artery) have a higher risk of rupture. Basilar artery aneurysms represent only 3–5% of all intracranial aneurysms but are the most common aneurysms in the posterior circulation.

Minor workers have rectangular heads with weakly convex posterior margins in full face view Major workers have reddish brown to blackish brown bodies. Their heads are proportionately larger and almost square with convex posterior margin in frontal view. Mandibles of major workers are large and triangular, with an acute apical "tooth".
See also: Insular CortexThis image divides the insula into its anterior, mid, and posterior regions, with each being denoted by different colors. The insula is critically involved in the processing, integration, and cortical representation of visceral and interoceptive information. Lamina I spinothalamic and vagal afferents project via the brainstem and thalamus to the posterior and mid dorsal insula respectively. From there, information travels to the posterior and mid-insula, which combines visceral and somatosensory information.
Species of Hindeodus are divided into two groups based on the morphology of the posterior portion of the elements. Species such as H.parvus and H.eurypyge grow posteriorly and look rectangular from a lateral perspective. Elements grow by the addition of new denticles to the posterior margin. After one denticle fully grows, a bulge begins to form on the lower posterior margin of the element, and gradually grows upward until the denticle fully develops.
Genital ridges secrete a chemoattractant causing PGCs migration. Around week three, the mesenchyme cells migrate around the cloacal membrane forming a pair of cloacal folds laterally around the cloacal membrane. From week six, the anterior cloacal folds fuse to form genital tubercle, the posterior cloacal folds divide into anterior urogenital folds and posterior anal folds. The cloacal membrane, divides into urogenital and anal membranes, breaks to form anterior urogenital opening and posterior anal opening respectively.
The teres minor originates at the lateral border and adjacent posterior surface of the scapula. It inserts at the greater tubercle of the humerus. The tendon of this muscle passes across, and is united with, the posterior part of the capsule of the shoulder-joint.
These travel outwards, around the superior cerebellar peduncles, and along the top of the cerebellar tentorium, where it sends branches to supply the temporal and occipital lobes. Each posterior cerebral artery sends a small posterior communicating artery to join with the internal carotid arteries.
Surgical management options include extensive cervical laminectomy with or without an additional posterior arthrodesis, anterior decompression and arthrodesis, and posterior cervical laminoplasty.

English-speaking medical students use the phrase in memorizing the order of an artery, and a nerve, and the three tendons of the flexor retinaculum in the lower leg: the T, D, A, N and H of Tom, Dick, and Harry correspond to tibialis posterior, flexor digitorum longus, posterior tibial artery, tibial nerve, and flexor hallucis longus. This mnemonic is used to remember the order of the tendons from anterior to posterior at the level of the medial malleolus just posterior to the malleolus.Netter, Frank H. (2011) Atlas of Human Anatomy, 5th Ed. Saunder: Philadelphia. A variation of this is Tom Dick And Very Nervous Harry.
The development of the posterior cerebral artery (PCA) in the fetal brain occurs relatively late and arises from the fusion of several embryonic vessels near the caudal end of the posterior communicating artery. The PCA begins as a continuation of the posterior communicating artery in 70-90% of fetuses with the remainder of PCAs having a basilar origin. The fetal carotid origin of the PCA usually regresses as the vertebral and basilar arteries become dominant and it finds a new origin in the basilar artery. About 20% of adults retain PCA origin from the posterior communicating artery, and in turn, the internal carotid arteries.
The intact teeth in GAA 00246-2 are smaller than the teeth anterior and posterior to them, and they carry the same kind of vertical fluting lingually as seen in the upper teeth. The apex of each tooth carries anterior and posterior carinae, with a slight hint of an accessory cusp associated with the fanning of the anterior fluting from the central cone of tooth. There is no evidence of a posterior cusp where the fluting extends to the posterior carina. These teeth also appear to have a slightly posteriorly tilted central cone, but in typical caseid fashion there is clear evidence of a pronounced lingual tilt to the crown.
Researchers suggest that mesoderm invagination provides an anterior-posterior pulling force that contributes to germ-band extension through passive cell shape changes. Although anterior-posterior patterning mutants fail to fully extend their germ-bands, during the fast phase the elongation length is normal despite defects in polarized cell intercalation. Time-lapse analysis revealed that an increase in cell shape stretching in the anterior-posterior axis was compensating for aberrant cell intercalation, independent of anterior-posterior patterning. Furthermore, during wild type development, it has been suggested that intercalary cell behavior relaxes the stress imposed on the germ-band, allowing stretched cells to restore to isometric shapes.
A second spiral of similar character and almost equal elevation is a short distance behind it, the two separated from one another by a shallow interspace in which a medial secondary and two microscopically fine tertiaries are symmetrically intercalated. Both of the peripheral spirals are broadly and regularly scalloped by the axial undulations. The area between the posterior peripheral primary and the posterior suture is feebly concave, lirated with a strongly elevated primary directly in front of the suture and 3 equal and closely spaced secondaries between the posterior primary and the posterior peripheral spiral. A microscopically fine tertiary in some specimens is introduced directly behind the periphery.
In the coronary circulation, the posterior interventricular artery (PIV, PIA, or PIVA), most often called the posterior descending artery (PDA), is an artery running in the posterior interventricular sulcus to the apex of the heart where it meets with the anterior interventricular artery or also known as Left Anterior Descending artery. It supplies the posterior third of the interventricular septum. The remaining anterior two-thirds is supplied by the anterior interventricular artery which is a septal branch of the left anterior descending artery, which is a branch of left coronary artery. It is typically a branch of the right coronary artery (70%, known as right dominance).
The first-order neuron is a left When an action potential is generated by a mechanoreceptor in the tissue, the action potential will travel along the peripheral axon of the first- order neuron. The first-order neuron is pseudounipolar in shape with its body in the dorsal root ganglion. The action signal will continue along the central axon of the neuron through the posterior root, into the posterior horn, and up the posterior column of the spinal cord. Axons from the lower body enter the posterior column below the level of T6 and travel in the midline section of the column called the gracile fasciculus.
Species of the family Moniliformidae are usually pseudosegmented and have a cylindrical proboscis with longitudinal rows of hooks that have posteriorly directed roots. Moniliformidae are further characterized by the presence of a simple, double-walled proboscis receptacle with the outer wall having spirally aligned muscle fibers (with the exception of Australiformis), brain at posterior end of receptacle, and dorsal and ventral lacunar canals. The proboscis retractor muscles pierce both the posterior and ventral end or just posterior end of the receptacle. The cerebral ganglion is in the imd to posterior region, and the lemnisci are long and flat and not bound to the body wall.
In humans, the soleus is a complex, multi-pennate muscle, usually having a separate (posterior) aponeurosis from the gastrocnemius muscle. A majority of soleus muscle fibers originate from each side of the anterior aponeurosis, attached to the tibia and fibula. Other fibers originate from the posterior (back) surfaces of the head of the fibula and its upper quarter, as well as the middle third of the medial border of the tibia. The fibers originating from the anterior surface of the anterior aponeurosis insert onto the median septum and the fibers originating from the posterior surface of the anterior aponeurosis insert onto the posterior aponeurosis.
No trypsin activity occurs before the blood meal, but activity increases continuously up to 30 hours after feeding, and subsequently returns to baseline levels by 60 hours. Aminopeptidase is active in the anterior and posterior midgut regions before and after feeding. In the whole midgut, activity rises from a baseline of approximately three enzyme units (EU) per midgut to a maximum of 12 EU at 30 hours after the blood meal, subsequently falling to baseline levels by 60 hours. A similar cycle of activity occurs in the posterior midgut and posterior midgut lumen, whereas aminopeptidase in the posterior midgut epithelium decreases in activity during digestion.

It arises from the posterior surface and lateral border of one arytenoid cartilage, and is inserted into the corresponding parts of the opposite cartilage. It consists of oblique and transverse parts.
Zooxanthellae in the zoospore stage exhibit motility as forward movement or gyratory movement. In moving forward, the organism rotates on the posterior flagellum’s axis whilst simultaneously propelling through the water column. The zoospore gyrates through the water column via attachment of the posterior flagellum to a substrate.

The articulation of all the vertebrae together is very snakelike. Yet the construction of the vertebrae themselves are very unlike such. The anterior vertebrae are smaller than the more posterior. The neural arches grow to be more swollen moving anterior to posterior, indicative of pachystotic nature.
The anterior edge is host to up to fifteen teeth while the posterior edge has a maximum of ten. The Trigonoconcha ranges in shell length from and has a height between . When described, the genus name Trigonoconcha was chosen by Sánchez in reference to the triangle created by the anterior and posterior margins of the shell. Similarly, the species epithet acuta was coined as a reference to the acute angle formed by the anterior and posterior margins.
The posterior part of the medulla between the posterior median sulcus and the posterolateral sulcus contains tracts that enter it from the posterior funiculus of the spinal cord. These are the gracile fasciculus, lying medially next to the midline, and the cuneate fasciculus, lying laterally. These fasciculi end in rounded elevations known as the gracile and the cuneate tubercles. They are caused by masses of gray matter known as the gracile nucleus and the cuneate nucleus.
When listening to semantic jokes, the left posterior middle temporal gyrus was again activated, as were the left posterior inferior temporal gyrus, the right posterior middle temporal gyrus, and the cerebellum. Brain activity in the medial ventral prefrontal cortex was associated with ratings of funniness that the participants gave after the brain scan and initial humor response. This response may stem from the mood or emotional change that occurs after hearing humor.Goel, V., & Dolan, R. (2001).
The siphonal notch is a noticeable notch situated at the most posterior part of the aperture of the shell, through which the siphon is extended when the animal is active. The notch at the posterior end of the aperture is also called the anal notch, anal sinus, anal canal or posterior canal. Instead of a simple siphonal notch, some gastropods have an elongated siphonal canal, a hard shell tube which extends out from the anterior edge of the aperture.
After gathering the function evaluations, which are treated as data, the prior is updated to form the posterior distribution over the objective function. The posterior distribution, in turn, is used to construct an acquisition function (often also referred to as infill sampling criteria) that determines the next query point. There are several methods used to define the prior/posterior distribution over the objective function. The most common two methods use Gaussian Processes in a method called Kriging.
These previous studies reflective the premise of the study, that the Aha! effect occurs in the anterior cingulate cortex, while this study finds results indicating the posterior cingulate cortex is responsible. It was found that there was a N350 in the posterior cingulate cortex for successful guessing of logographs, not in the anterior cingulate cortex. The posterior cingulate cortex seems to play a more non-executive function in monitoring and inhibiting the mind set and cognitive function.
The pituitary gland is divided into two sections: the anterior pituitary and the posterior pituitary. The hypothalamus controls the anterior pituitary's hormone secretion by sending trophic hormones down the hypothalamohypophysial portal system. For example, thyrotropin-releasing hormone stimulates the secretion of thyroid-stimulating hormone by the anterior pituitary. The posterior pituitary is innervated by the hypothalamus; the hormones oxytocin and vasopressin are synthesized by neuroendocrine cells in the hypothalamus and stored at the nerves' ends in the posterior pituitary.
Tachina sp. fly showing white calypters at the base of the wings Tachinid A calypter is either of two posterior lobes of the posterior margin of the forewing of flies between the extreme posterior wing base and the alula, which covers the halteres. The lower calypter is the proximal calypter (synonyms: squama (of some authors), tegula ) and the upper calypter is the distal calypter (synonym: squamula). Species of the subsection Acalyptratae are noted for lacking calypters.
Neurons in higher auditory pathway centers are tuned to specific stimuli features, such as periodicity, sound intensity, amplitude and frequency modulation. There are also neuroanatomical associations of ASA through the posterior cortical areas, including the posterior superior temporal lobes and the posterior cingulate. Studies have found that impairments in ASA and segregation and grouping operations are affected in patients with Alzheimer's disease.Goll, J., Kim, L. (2012), "Impairments of auditory scene analysis in Alzheimer's disease", Brain 135 (1), 190-200.
This posterior neuron produces a train of impulses, which excites the other posterior neurons. The heart contracts when the posterior neurons activate the five anterior neurons, which send impulses to the muscle cells. This is how the Frank–Starling mechanism works within crustaceans. The Frank-Starling mechanism refers to the vitally important intrinsic control of the heart; mainly, the stretching of the cardiac muscle tends to increase the force of its contraction by an effect at the cellular level.
The auricular branch of posterior auricular artery is a small artery in the head. It branches off the posterior auricular artery and ascends behind the ear, beneath the posterior auricular muscle, and is distributed to the back of the auricula, upon which it ramifies minutely, some branches curving around the margin of the cartilage, others perforating it, to supply the anterior surface. It anastomoses with the parietal and anterior auricular branches of the superficial temporal artery.
The posterior semicircular canal is a part of the vestibular system that detects rotation of the head around the antero-posterior (sagittal) axis, or in other words rotation in the coronal plane. This occurs, for example, when you move your head to touch your shoulders, or when doing a cartwheel. It is directed superiorly, as per its nomenclature, and posteriorly, nearly parallel to the posterior surface of the petrous bone. The vestibular aqueduct is immediately medial to it.
The Bicoid protein blocks translation of caudal mRNA so Caudal protein is of lower concentration at the anterior part of the embryo and at higher concentration at the posterior part of the embryo. This is of opposite direction of the Bicoid protein. The caudal protein then activates later to turn genes on to form the posterior structures during the segmentation phase. Nanos protein creates a posterior-to-anterior slope and is a morphogen that helps in abdomen formation.
The anterior side of the coccyx has attachments to the levator ani muscle, coccygeus, iliococcygeus, and pubococcygeus, anococcygeal raphe. Attached to the posterior side is the gluteus maximus, which extends the thigh at the hip joint. The ligaments attached to the coccyx include the anterior and posterior sacrococcygeal ligaments which are the continuations of the anterior and posterior longitudinal ligaments that stretches along the entire spine. The lateral sacrococcygeal ligaments complete the foramina for the last sacral nerve.
There are three distinct routes from the dentate nucleus to the ventrolateral thalamus, including a direct, posterior, and anterior route. The direct route passes in the anterolateral direction under the thalamus and enters from the ventral side. Axons following the posterior pathway turn dorsally from the midline at the posterior side of the thalamus, entering the thalamus from various positions. Axons following the anterior route pass laterally in the subthalamus and enter the external medullary lamina.
Bicoid and Nanos both encode morphogens that have the opposite effect on Hunchback mRNA translation – Bicoid activates translation, whereas Nanos represses it. As such, Hunchback mRNA is translated so that Hunchback protein is present in the concentration gradient which decreases along the anterior – posterior axis. This Hunchback gradient indirectly results in an anterior boundary for Knirps expression. Other factors induce a posterior boundary, so that Knirps is expressed in a stripe in the posterior region of the embryo.
The center of the hypostome is an ovoid, typically convex part called the median body, often divided into an anterior lobe and a posterior lobe. Either side of the median body is a border with various extensions, including anterior and posterior wings, sometimes bearing knob-like processes. The hypostome is hollow, and encloses the mouthparts, the anterior digestive tract, and the bases of the antennae. Trilobite antennae pass through notches between the anterior and posterior wings, then forward.
Apex posterior, extending a little beyond the margin, with a spiral nucleus of 1 whorl, visible on the right side. The apex is generally on the left side, but sometimes near the middle of the posterior margin. The aperture is large, oval, the thin sharp margin generally rounded, but the posterior part of it is occasionally straightened and forming more or less distinct angles with the lateral sides, which themselves may become almost straight. The inside is polished.
In the United States acetabular labrum tears usually occur in the anterior or anterior-superior area, possibly due to a sudden change from labrum to acetabular cartilage. The most common labrum tears in Japan are in the posterior region, likely due to the customary practice of sitting on the floor. Posterior labrum tears in the Western world usually occur when a force drives the femoral head posteriorly which transfers shear and compressive forces to the posterior labrum.
These arteries, together with the pancreatic branches of the splenic artery, form connections or anastomoses with one another, allowing blood to perfuse the pancreas and duodenum through multiple channels. The artery supplies the anterior and posterior sides of the duodenum and head of pancreas, with the anterior branch supply the anterior surface and similarly for the posterior. At 42 letters, the posterior superior pancreaticoduodenal artery is also the artery with the longest name in the human body.
In contrast to other Osteolepiformes, which similarly possess a posterior supraorbital bone that extends ventrally along the orbital fenestra, the contact with the lachrymal by the posterior supraorbital bone is a diagnostic character of Eusthenodon and results in the separation of the jugal and postorbital bones from meeting the orbital fenestra. The positions and relative sizes of additional fenestra present in Eusthenodon, including the fenestra exonarina, pineal foramen, and pineal fenestra are further diagnostic characters of the genus. The triangular pineal fenestra is well known in Eusthenodon for its large size and the distinctive posterior tail of the fenestra coming near or in-contact to the posterior frontal margin. On the contrary, the pineal foramen is much smaller in size and is positioned distinctively posterior both to the center of radiation of the frontal and the postorbital bone of the frontoethmoidal shield.
At the side of the articular processes are the four posterior sacral foramina; they are smaller in size and less regular in form than those at the front, and transmit the posterior divisions of the sacral nerves. On the side of the posterior sacral foramina is a series of tubercles, the transverse processes of the sacral vertebrae, and these form the lateral sacral crest. The transverse tubercles of the first sacral vertebra are large and very distinct; they, together with the transverse tubercles of the second vertebra, give attachment to the horizontal parts of the posterior sacroiliac ligaments; those of the third vertebra give attachment to the oblique fasciculi of the posterior sacroiliac ligaments; and those of the fourth and fifth to the sacrotuberous ligaments. Lateral surface The lateral surface of the sacrum is broad above, but narrows into a thin edge below.
Functionally, the external ear is served by three (3) ear muscles, the auricularis posterior muscle (rear ear-muscle), the auricularis superior muscle (upper ear-muscle), and the auricularis anterior muscle (front ear-muscle), the most notable of which is the auricularis posterior muscle, which functions to pull the ear backwards, because it is superficially attached to the ponticulus (bridge) of the conchal cartilage, and to the posterior auricular ligament (rear ligament of the ear). The posterior muscle of the ear is composed of 2–3 fascicles (skeletal-muscle fibers contained in perimysium connective tissue), originates from the mastoid process of the temporal bone and is inserted to the lower part of the cranial surface of the concha, where it is surrounded by fibroareolar tissue deep within the temporal fascia. The posterior auricular artery irrigates the ear tissues with small, branch-artery blood vessels (rami). Likewise, the rear muscle of the ear is innervated with fine rami of the posterior auricular nerve, which is a branch of the facial nerve.
On core jakobids and excavate taxa: The ultrastructure of Jakoba incarcerata. Journal of Eukaryotic Microbiology, 48(4), 480-492. doi:10.1111/j.1550-7408.2001.tb00183.x.. The anterior flagella are usually shorter than the body length while the posterior flagella are usually more than twice longer than the cell; the posterior flagella of S. incarcerata are generally shorter, usually about 1.5 times the cell length The anterior flagellum of S. incarcerata has single root made of two slightly separated microtubules, which originates close to the anterior basal body in the ventral, posterior end.. The posterior flagellum has two main microtubular roots: the left one is associated with three different non- microtubular fibres as well as a composite fibre, and the right one of one type. In addition, a singlet “root” circles the posterior basal body and supports the shape of the groove A dorsal vane attaches on the posterior flagellum, which is supported by a paraxonemal lamella that originates near the axoneme.. The axoneme is composed of the typical eukaryotic 9 x 2 motif.

Cytoarchitectonically, the lateral and medial sides of the MFS are dissociable. The anterior and posterior portion of the MFS also have different long-range connections. The vertical occipital fasciculus terminates in the posterior aspects of the MFS, while the arcuate fasciculus terminates in the anterior portions of the MFS.
The extensor digitorum muscle (also known as extensor digitorum communis) is a muscle of the posterior forearm present in humans and other animals. It extends the medial four digits of the hand. Extensor digitorum is innervated by the posterior interosseous nerve, which is a branch of the radial nerve.
The brain is supplied with blood by the internal carotid arteries and also by the posterior cerebral arteries; the posterior communicating arteries connects the two systems. This provides redundancies or collaterals in the cerebral circulation so that, if one system is blocked or narrowed, the other can take over.
Her technique has also permitted her to shed light on the development of the blood and immune systems. Her work on antero-posterior patterning of the vertebrate digestive tract laid the grounds for future work, leading to a better understanding of antero-posterior patterning in the digestive tract.
The anterior lobes of the foot show a posterior right angle. The posterior end of the foot has a folded tubercle that is not divided by longitudinal wrinkle in the middle. The distal extremities of the fins are rounded. It lacks a shell except during its early embryonic stage.
Lightbulb sign indicative of posterior shoulder dislocation shown on the left. On the right, the same shoulder after reduction. Posterior dislocations are uncommon, and are typically due to the muscle contraction from electric shock or seizure. They may be caused by strength imbalance of the rotator cuff muscles.
Studies have shown that the earliest serotonergic neurons were started in the anterior rhombomeres. The most dorsal group of neurons originated from rhombomere 1, and the posterior raphe—which forms from the rhombomeres—is believed to derive from the posterior rhombomeres at a slightly later stage of embryonic development.

5th edition. Dee Unglaub Silverthorn It fills both the anterior and the posterior chambers of the eye, and is not to be confused with the vitreous humour, which is located in the space between the lens and the retina, also known as the posterior cavity or vitreous chamber.
Haglund's syndrome is a group of symptoms: Haglund deformity (which is an exostosis of the posterior calcaneal tuberosity) in combination with retrocalcaneal bursitis. It is often accompanied by Achilles tendinitis. Haglund deformity typically presents with a prominent bump on the upper posterior calcaneus. Its causes are not fully understood.
1 at right: # Opisthokont. Posterior whiplash flagella, a characteristic of Chytridiomycota, and a proposed uniting trait of the Opisthokonts, a large clade of eukaryotes containing animals and fungi. In most of these, there is a single posterior flagellum (Fig. 1a), but in Neocallimastigales, there are up to 16 (Fig.
The posterior angle is acute. The shell is slightly channeled anteriorly. The outer lip is thin, with a white band at the periphery. The remainder is brown with darker colored lines, reinforced deeply within by five spiral cords, two of which are posterior and three anterior to the periphery.
During sexual intercourse in the missionary position, the tip of the penis reaches the anterior fornix, while in the rear-entry position it reaches the posterior fornix. The fornices appear to be close to one reported erogenous zone, the cul-de-sac, which is near the posterior fornix.
The posterior humeral circumflex artery (posterior circumflex artery, posterior circumflex humeral artery) arises from the third part of axillary artery at the lower border of the subscapularis, and runs posteriorly with the axillary nerve through the quadrangular space. It winds around the surgical neck of the humerus and is distributed to the deltoid muscle and shoulder- joint, anastomosing with the anterior humeral circumflex and deep artery of the arm. It supplies the teres major, teres minor, deltoid, and (long head only) triceps muscles.
Pimenta's Point is an anatomical landmark for easy location of the posterior tibial artery or tibialis posterior artery (a peripheral pulse on the inside of your ankle). An imagined line is drawn between the bony prominence of the medial malleolus and the insertion of the achilles tendon. At the exact midpoint of this line place three fingers parallel to the leg and you will either feel the posterior tibial pulsation (normal) or will not (peripheral vascular disease or calcification, anatomical variant).
The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle. Their mastoid lymph nodes receives lymph from the posterior part of the temporoparietal region, the upper part of the cranial surface of the visible ear and the back of the ear canal. The lymph then passes to the superior deep cervical glands.
Sonic hedgehog is turned on in the posterior region via the early expression of HoxD genes, along with the expression of Hoxb8. Shh is maintained in the posterior through a feedback loop between the ZPA and the AER. Shh cleaves the Ci/Gli3 transcriptional repressor complex to convert the transcription factor Gli3 to an activator, which activates the transcription of HoxD genes along the anterior/posterior axis. It is evident that different Hox genes are critical for proper limb development in different amphibians.
The dorsal ramus of spinal nerve (or posterior ramus of spinal nerve, or posterior primary division) is the posterior division of a spinal nerve. The dorsal ramus (Latin for branch, plural rami ) is the dorsal branch of a spinal nerve that forms from the dorsal root of the nerve after it emerges from the spinal cord. The spinal nerve is formed from the dorsal and ventral rami. The dorsal ramus carries information that supplies muscles and sensation to the human back.
The term posterior cortical hot zone was coined by Christof Koch and colleagues to describe the part of the neocortex closely associated with the minimal neural substrate essential for conscious perception. The posterior cortical hot zone includes sensory cortical areas in the parietal, temporal, and occipital lobes. It is the “sensory” cortex, much as the frontal cortex is the “action” cortex. When parts of the posterior cortex are damaged, whole modalities of sensory experience disappear from both waking and dreaming.
The posterior tibial artery pulse can be readily palpated halfway between the posterior border of the medial malleolus and the achilles tendon and is often examined by physicians when assessing a patient for peripheral vascular disease. It is very rarely absent in young and healthy individuals; in a study of 547 healthy individuals only one person did not have a palpable posterior tibial artery.Robertson GS, Ristic CD, Bullen BR. The incidence of congenitally absent foot pulses. Ann R Coll Surg Engl.
The DNA base excision repair pathway has a central role in the process of genome-wide demethylation. Upon commencement of gastrulation, the primitive streak, a visible, morphological groove, appears on the posterior epiblast and orients along the anterior- posterior embryo axis. Initiated by signals from the underlying hypoblast, formation of the primitive streak is predicated on epiblast cell migration, mediated by Nodal, from the lateral-posterior regions of the epiblast to the center midline.Shen MM. Nodal signaling: developmental roles and regulation.
Each segment, except for the anal segment, had a belt of small, well-developed spines going towards the posterior margins. The anterior and posterior regions were similarly narrow while the middle appeared broad. Two hooks were found on the pseudo-cephalic segment of the maggot which enabled them to attach to the mucosal lining of the intestine. The appearance of spiracular slits on the solid plate on the peritreme of the posterior spiracle narrowed the results down to the genus Muscina.
When the cast is removed, the AFO is worn to prevent the foot from returning to the old position. For feet with partial correction of deformity with non-operative treatment, surgery may be less extensive and may involve only the posterior part of the foot and ankle. This might be called a posterior release. This is done through a smaller incision and may involve releasing only the posterior capsule of the ankle and subtalar joints, along with lengthening the Achilles tendon.
The posterior cingulate cortex lies behind the anterior cingulate cortex, forming a part of the posteromedial cortex, along with the retrosplenial cortex (Brodmann areas 29 and 30) and precuneus (located posterior and superior to the PCC). The PCC, together with the retrosplenial cortex, forms the retrosplenial gyrus. The posterior cingulate cortex is bordered by the following brain regions: the marginal ramus of the cingulate sulcus (superiorly), the corpus callosum (inferiorly), the parieto-occipital sulcus (posteriorly), and Brodmann area 24 (anteriorly).
In the sphenoid bone, the anterior boundary of the sella turcica is completed by two small eminences, one on either side, called the anterior clinoid processes, while the posterior boundary is formed by a square-shaped plate of bone, the dorsum sellæ, ending at its superior angles in two tubercles, the posterior clinoid processes, the size and form of which vary considerably in different individuals. The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli.
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 deltoid is innervated by the axillary nerve. The axillary nerve originates from the anterior rami of the cervical nerves C5 and C6, via the superior trunk, posterior division of the superior trunk, and the posterior cord of the brachial plexus. Studies have shown that there are seven neuromuscular segments to the deltoid muscle. Three of these lie in the anatomical anterior head of the deltoid, one in the anatomical middle head, and three in the anatomical posterior head of the deltoid.
The superficial temporal vein is a vein of the side of the head. It begins on the side and vertex of the skull in a network of veins which communicates with the frontal vein and supraorbital vein, with the corresponding vein of the opposite side, and with the posterior auricular vein and occipital vein. It ultimately crosses the posterior root of the zygomatic arch, enters the parotid gland, and unites with the internal maxillary vein to form the posterior facial vein.
The left bundle branch subdivides into two fascicles: the left anterior fascicle and the left posterior fascicle. Other sources divide the left bundle branch into three fascicles: the left anterior, the left posterior, and the left septal fascicle. The thicker left posterior fascicle bifurcates, with one fascicle being in the septal aspect. Ultimately, the fascicles divide into millions of Purkinje fibres, which in turn interdigitate with individual cardiac myocytes, allowing for rapid, coordinated, and synchronous physiologic depolarization of the ventricles.
Symptoms relate to impaired brain function in areas supplied by the posterior circulation, as seen in posterior circulation strokes. However, symptoms may be far briefer than those seen in stroke. Vertigo is a relatively common symptom that can result from ischemia to the cerebellum, medulla or (rarely) the internal auditory artery which supplies the vestibular system of the inner ear. While vertigo is a common feature of VBI or posterior circulation stroke, VBI only rarely presents with vertigo alone (without other neurological signs).
At the outside centre points of both arches there is a tubercle, an anterior tubercle and a posterior tubercle, for the attachment of muscles. The front surface of the anterior arch is convex and its anterior tubercle gives attachment to the longus colli muscle. The posterior tubercle is a rudimentary spinous process and gives attachment to the rectus capitis posterior minor muscle. The spinous process is small so as not to interfere with the movement between the atlas and the skull.
Females have one ovary and the vulva located posterior. Males possess small spicules and small bursae or alae.
For some authors, the deep branch of the radial nerve is the same as the posterior interosseous nerve.

For vertebrate lenses, measures of anterior and posterior spheroidicity are required because these lenses are asymmetrical, oblate spheroids.
A similar enlargement of the chondral junctions of the sternum may be found on examining its posterior surface.
Axons from the upper body enter at or above T6 and travel up the posterior column on the outside of the gracile fasciculus in a more lateral section called the cuneate fasciculus. These fasciculi are in an area known as the posterior funiculus that lies between the posterolateral and the posterior median sulcus. They are separated by a partition of glial cells which places them on either side of the posterior intermediate sulcus. The column reaches the junction between the spinal cord and the medulla oblongata, where lower body axons in the gracile fasciculus connect (synapse) with neurons in the gracile nucleus, and upper body axons in the cuneate fasciculus synapse with neurons in the cuneate nucleus.
The space within the triangle is dark brown; but the parts, near the shoulders, are lighter, having a greyish cast or hue, and contain many small transverse curved streaks, extending to the anterior edges, where they are large, black, and very conspicuous, like stripes. Some transverse markings of this kind, are dispersed on the posterior edges of the superior wings, and also on the abdominal edges of the posterior. On the outside the triangle, both on the anterior and posterior wings, is a fascia, of light brown, about half an inch broad, which deepens into a dark brown. On the posterior wings, after becoming dark, it softens again into the same light colour, continuing to the external edges.
A case study described recently in The Irish Medical Journal discussed the role the posterior commissure plays in the connection between the right occipital cortex and the language centers in the left hemisphere. This study explains how visual information from the left side of the visual field is received by the right visual cortex and then transferred to the word form system in the left hemisphere though the posterior commissure and the splenium. Disruption of the posterior commissure can cause alexia without agraphia. It is evident from this case study of alexia without agraphia that the posterior commissure plays a vital role in transferring information from the right occipital cortex to the language centers of the left hemisphere.
The superior part of the posterior border constitutes the habenular commissure, while more centrally it the pineal gland, which regulates sleep and reacts to light levels. Caudal of the pineal gland is the posterior commissure; nerve fibres reach the posterior commissure from the adjacent midbrain, but their onward connection is currently uncertain. The commissures create concavity to the shape of the posterior ventricle border, causing the suprapineal recess above the habenular, and the deeper pineal recess between the habenular and posterior commissures; the recesses being so-named due to the pineal recess being bordered by the pineal gland. The hypothalmic portion of the third ventricle (upper right), and surrounding structures The anterior wall of the ventricle forms the lamina terminalis, within which the vascular organ monitors and regulates the osmotic concentration of the blood; the cerebrum lies beyond the lamina, and causes it to have a slightly concave shape.
A modification in the posterior end of the esophagus forms a muscular posterior bulb, which can generate a pumping action similar to that of a metacorpus in other plant parasitic nematodes. The lumen of esophageal bulb contains 3 ducts which allow for the passage of secretions from the esophageal glands.
The maxillary sinus is supplied by superior alveolar nerves from the maxillary and infraorbital nerves. The frontal sinus is supplied by branches of the supraorbital nerve. The ethmoid sinuses are supplied by anterior and posterior ethmoid branches of the nasociliary nerve. The sphenoid sinus is supplied by the posterior ethmoidal nerves.
The frontal part of the scalp is drained to the parotid, submandibular, and deep cervical lymph nodes. The posterior part is drained to the posterior auricular and occipital lymph nodes. Malignancies of the scalp can metastasize to these lymph nodes. Brain tumors, however, tend to metastasize haematogenously (through the blood).
The fibular artery typically arises from the posterior tibial artery. Therefore, the posterior tibial artery proximal to the fibular artery origin is sometimes called the tibial-peroneal trunk or tibial-fibular trunk and it could be said that the popliteal artery bifurcates into the tibial-fibular trunk and anterior tibial artery.
A few sources include the pars intermedia as part of the posterior lobe, but this is a minority view. It is based upon the gross anatomical separation of the posterior and anterior pituitary along the cystic remnants of Rathke's pouch, causing the pars intermedia to remain attached to the neurohypophysis.
The little developed median frontal lobe is rounded. The drawn out lateral lobes are equal in length and width of the eyes or the face. Both epimera, posterior margin, posterior angles, and the first three segments of the thorax are straight. The fifth, sixth, and seventh segments are bend backwards.
The posterior interventricular artery, a branch of right coronary artery, supplies the posterior 1/3 of the interventricular septum. The remaining anterior 2/3 is supplied by the anterior interventricular artery which is a septal branch of the left anterior descending artery, which is a branch of left coronary artery.
The surgery aims to cover the thinning posterior pole with a supportive material to withstand intraocular pressure and prevent further progression of the posterior staphyloma. The strain is reduced, although damage from the pathological process cannot be reversed. By stopping the progression of the disease, vision may be maintained or improved.
The nasal is also dotted with tiny foramina. Progalesaurus has a parietal foramen, which is used for light sensing in extant taxa. Posterior to the parietal foramen the parietals are fused, forming a sagittal crest. The crest narrows posterior to the foramen like Galesaurus and Cynosaurus, and unlike more derived cynodonts.
The species was once confused with Pseudophilautus rus. However new studies revealed that P. conniffae is different from its relative in many ways. It has a conical median lingual process which is absent in P. rus. Black patches are found on the posterior flank, anterior and posterior edges of the thigh.
P2–M2 have two widely separated roots, accessory denticles on the anterior and posterior cutting edges, and anastomosing striae on the enamel. P1 is caniniform with a single root. P2–4 have laterally compressed crowns and accessory denticles on the anterior and posterior cutting edges. P4 is the largest lower tooth.
Scissor bite is a type of bite seen in some mammals such as dogs and humans. This type of bite involves outward positioning of the upper posterior teeth and inward positioning of the lower posterior teeth. The reason for this happening is an expanded upper arch and constricted lower arch.
The posterior proper fasciculus arises from cells in the posterior column; their axons bifurcate (fork) into ascending and descending branches which occupy the ventral part of the funiculus close to the grey column. They are intersegmental and run for varying distances sending off collaterals and terminals to the grey matter.
Colobopsis anderseni is light brown and glossy. Like any arthropod, its body contains three sections. The first part is called the prosoma while the middle part is called the mesosoma, and the posterior part is called the metasoma. The dorsum, or posterior side, of the mesosoma on C. anderseni is flattened.
The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain. Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome.
Its highest point reaches 2.1mm forming a blunt tip and concave posterior outline on the shorter edge. The jawbone is approximately 1m thick. The anterior end represents the antorbital part of the jaw. A notable posterior concave outline represents the orbital opening as well as the beginning of the lacrimal.
The tail is marked by acrescent-shaped fold in the cuticle surrounding the posterior portion of the cloacal opening.
The eminentia conchae is crossed by a vertical ridge, the ponticulus, which gives attachment to the Auricularis posterior muscle.
Brain stroke in a region affecting auditory function such as a posterior circulation infarct has been associated with deafness.
The presence of a freely protruding lip at the posterior portion of the columella is also a distinctive character.
The posterior half of the forewings is white. The hindwings are light grey. Adults are on wing in June.
The osteoderms are compressed inwards from the side, have a slope positioned anteriorly, and a square-shaped posterior edge.
It is pierced by posterior division of the obturator nerve as well as the middle genicular nerve and vessels.
Left posterior cerebral artery syndrome presents alexia without agraphia; the lesion is in the splenium of the corpus callosum.
Toes have rudimentary webbing. Tarsal fold is absent. Calcar is absent. Snout, interorbital area and posterior dorsum are smooth.
This is created by the Nanos protein whose existence is at a declining slope from posterior to anterior ends.
Like all the muscles in the posterior forearm, ECR brevis is supplied by a branch of the radial nerve.
Both lungs are innervated primarily by the posterior pulmonary plexus; it accounts for 74–77% of the total innervation.
In this thyroplasty, the relaxation of the vocal cords is done by antero-posterior shortening of the thyroid ala.
The body is elongated. The posterior margin of the third tergite of the abdomen shows three small wide teeth.
The myelencephalon or afterbrain is the most posterior region of the embryonic hindbrain, from which the medulla oblongata develops.
The sequence of the zoeal description is based on the malacostracan somite plan and described from anterior to posterior.
The labia majora are thicker in front, and form the anterior labial commissure where they meet below the mons pubis. Posteriorly, they are not really joined, but appear to become lost in the neighboring integument, ending close to, and nearly parallel to, each other. Together with the connecting skin between them, they form another commissure the posterior labial commissure which is also the posterior boundary of the pudendum. The interval between the posterior commissure and the anus, from 2.5 to 3 cm in length, constitutes the perineum.
The anterior end is deeply serrated and articulates with the zygomatic bone. The posterior end is connected to the squamous part by two roots, the anterior and posterior roots. The posterior root, a prolongation of the upper border, is strongly marked; it runs backward above the external auditory meatus, and is continuous with the temporal line. The anterior root, continuous with the lower border, is short but broad and strong; it is directed medialward and ends in a rounded eminence, the articular tubercle (eminentia articularis).
Vertical strokes are used on the anterior regions of the mouth and on the distal and mesial surfaces of the posterior teeth, while oblique strokes are used on the facial and lingual surfaces of the posterior teeth. When working on the line angles of posterior teeth and the midlines of the facial or lingual surfaces of anterior teeth, horizontal strokes are used. The number of strokes should be limited to areas where calculus is present as to minimize stress to the muscles of the hand.
Unusually, the posterior process of the maxilla extends as far back as the orbit, and about halfway along it, possibly even projecting into the orbit at points. The maxillary dental groove is extremely shallow, only deep. The lacrimal-nasal contact is elongated, so that the lacrimal, rather than the prefrontal, forms the posterior edge of the naris. The anterior process and shaft of the jugal are unusually narrow, but the posterior plate is well-developed and extends as high as the middle of the orbit.
The digestive organs include an anterior, terminal mouth, a muscular pharynx, and a posterior intestine with two lateral blind-ending branches. Each adult contains male and female reproductive organs. According to Ariola, the male reproductive organs include an anterior genital atrium with spines, posterior to the intestinal bifurcation; a vas deferens opening in the genital atrium; and a number of testes posterior to the ovary and arranged in two simple and parallel rows. Each testes has a canalicum, which sends its products in the common vas deferens.
The location of these lacerations is usually based on a woman's reproductive anatomy. It is common for women to have a uterus that lies slightly to the right, this exposes the right fornix and makes it easier for some type of tearing or trauma to occur. Lacerations to the posterior peri- cervical vagina tend to occur in the missionary position, hips and legs hyperflexed. Other positions can also expose the posterior vaginal wall that usually protected by the cervix, this allows for posterior fornix tears.
A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina. It refers to the separation of the posterior hyaloid membrane from the retina anywhere posterior to the vitreous base (a 3–4 mm wide attachment to the ora serrata). The condition is common for older adults; over 75% of those over the age of 65 develop it. Although less common among people in their 40s or 50s, the condition is not rare for those individuals.
It lies on the posterior aspect of the tibialis posterior and flexor digitorum longus muscles, and medial to the belly of flexor hallucis longus. It also gives rise to medial plantar artery and lateral plantar artery. During surgery, these neurovascular bundles, both superficial and deep, should be protected in order to prevent neurological damage. A common anatomically informed, surgical technique to avoid damaging neurovascular bundles is to undermine anteriorly to the posterior tibial margin after reaching the fascia, in order to avoid the saphenous vein and nerve.
The skull is anteriorly broad and posteriorly short relative to its length and is shallow dorsoventrally. The skull roof is deeper in the posterior portions because of a slight doming of the parietal bones and the angled ventral cheek margin. The posterior margin of the skull is slightly inclined anterodorsally, and the occipital bone follows this inclination, projecting slightly beyond the posterior margin of the skull. In dorsal view the outline of the skull roof is spade shaped with the cheek region wider than the skull table.
The frontal band of each of the lateral parts of the thorax segments (in the so-called pleural region) are not adorned. The posterior bands have a row of distinct small spines. The large tailshield (or pygidium) has 11 pairs of spines along the edge, and one in the middle, and 10–11 pairs of well-defined segments. The frontal pleural bands of each segment on the pygidium is lower compared to the posterior pleural band, and lacks the small spines of the posterior pleural band.
Unlike other tapeworms, the body of amphilinids is not divided into segments, instead being leaf-shaped and laterally flattened. There is a proboscis and several frontal glands at the anterior end, and an ovary and a seminal receptacle at the posterior end. The uterus extends from the posterior end, forward to the anterior end, back to the posterior end and then forward again to the anterior end, before opening at the female gonopore. Small testes and yolk cells are scattered throughout most of the tissue.
400px The Bithorax complex (BX-C) is one of two Drosophila melanogaster homeotic gene complexes, located on the right arm of chromosome 3. It is responsible for the differentiation of the posterior two-thirds (posterior thorax and each abdominal segment) of the fly by the regulation of three genes within the complex: Ultrabithorax (Ubx)', abdominal A (abd-A), and Abdominal B (Abd-B). A complete deletion of this complex results in the posterior segments of the Drosophila embryo becoming copies of the second thoracic segment.
The anterior meniscofemoral ligament (ligament of Humphry) is a small fibrous band of the knee joint. It arises from the posterior horn of the lateral meniscus and passes superiorly and medially in front of the posterior cruciate ligament to attach to the lateral surface of medial condyle of the femur. It may be confused for the posterior cruciate ligament during arthroscopy. In this situation, a tug on the ligament while observing for motion of the lateral meniscus can be used to tell the two apart.
The postcardinal veins or posterior cardinal veins join with the corresponding right and left cardinal veins to form the left common cardinal veins, which empty in the sinus venosus. Most of the posterior cardinal veins regress, what remains of them forms the renal segment of the inferior vena cava and the common iliac veins. Later in the development stages, the posterior cardinal veins are replaced by the subcardinal and supracardinal veins. The subcardinal veins form part of the inferior vena cava, renal veins and gonadal veins.
In the first vertebrae there are very large secondary protuberances on both sides of the hyposphene. The central and posterior vertebrae have an additional crest located between the posterior crest that extends from the lateral protrusion to the vertebral body and the secondary crest running parallel to the main crest. The frontal vertebrae of the tail have a protrusion in the posterior hyposphenic secondary joint. Choconsaurus was classified in its description article of 2017 within the clade Titanosauria in a basal position, outside the clade Eutitanosauria.
Posterior ramus syndrome, also referred to as thoracolumbar junction syndrome, Maigne syndrome and dorsal ramus syndrome is caused by the unexplained activation of the primary division of a posterior ramus of a spinal nerve (dorsal ramus of spinal nerve). This nerve irritation causes referred pain in a well described tri-branched pattern. The diagnosis is made clinically with the variable presence of four criteria. Descriptions of clinical involvement of posterior rami were found as early as 1893, but not until 1980 that LDRS was so precisely described.
Aminopeptidase in the anterior midgut is maintained at a constant, low level, showing no significant variation with time after feeding. Alpha-glucosidase is active in anterior and posterior midguts before and at all times after feeding. In whole midgut homogenates, alpha-glucosidase activity increases slowly up to 18 hours after the blood meal, then rises rapidly to a maximum at 30 hours after the blood meal, whereas the subsequent decline in activity is less predictable. All posterior midgut activity is restricted to the posterior midgut lumen.
The base, costal and posterior margins from the base to three-fourths are black greyish and there is a distinct dark spot at three- fourths of the posterior margin. The hindwings are grey. Adults are on wing in early May., 2005: A review of the genus Athrips (Lepidoptera: Gelechiidae) in the Palaearctic region .
A decrease in pain or apprehension or an increase in range of motion is a positive sign for anterior instability. Anterior pain may be caused by laxity in anterior ligaments or capsular structures or a tear of the labrum. Posterior pain may be caused from internal impingement of the posterior capsular or labrum.
The ZPA forms where the Hox8 region joins the AER. 250px These regions are dependent on signaling in order for the appropriate induction events to occur. The AER expresses FGF8 which induces Shh expression in the posterior mesoderm. Shh then stimulates FGF4 to be expressed in the posterior part of the AER.
Posterior edge of pronotum more or less straight or evenly rounded, or distinctly sinuate or variously lobed; simple; not or vaguely margined, or with narrow raised margin or bead. Discal carinae of pronotum absent, or located on posterior angles only. Pronotal disc without paired basal impressions. Pronotum without median longitudinal groove or line.
In average it measures 5–8 mm long and 3–5 mm wide. The disc-shaped body is divisible into anterior conical and posterior discoidal regions. The anterior region is a conical projection bearing a prominent oral sucker. The posterior portion is relatively broad, up to 8 mm wide, discoidal, and ventrally excavated.
A small scattering of setae occur on the body. Its posterior extremity is bilobed: the ventral portion bears stout, submedian, chitinous, upcurved processes, and each has an indistinct basal tooth anteriorly. The extremities at its posterior extremity are prehensile. The dorsal lobe is broad and obliquely truncate as seen from the side.
Morphological details of the Piopilidae The family differs from the closely related family Sepsidae in several characters, particularly in having the costa broken at the end of the subcosta, the setulose mesonotum and the absence of a hair or fine bristle arising on the posterior edge of the posterior spiracle of the thorax.
The tadpole of Microhyla rubra has a transparent body with a long, tapering whip like tail. In dorsal view, body clearly differentiated into two parts, a longer and wider anterior region and a narrower posterior region. Anterior region almost twice as long and wide as posterior region. Eyes small and snout rounded.
The posterior cutaneous nerve of forearm is a nerve found in humans and other animals. It is also known as the dorsal antebrachial cutaneous nerve, the external cutaneous branch of the musculospiral nerve, and the posterior antebrachial cutaneous nerve. It is a cutaneous nerve (a nerve that supplies skin) of the forearm.
Anne K. Churchland is a neuroscientist at Cold Spring Harbor Laboratory. Her laboratory studies the function of the posterior parietal cortex in cognitive processes such as decision-making and multisensory integration. One of her discoveries is that individual neurons in rodent posterior parietal cortex can multitask i.e. play a role in multiple behaviors.
The forewings are dark grey, the posterior half irrorated (sprinkled) with black and with a slightly curved moderate white postmedian fascia, anteriorly black edged, the posterior edge suffused with grey.

The parietal wall is thinly glazed. The anterior canal is long, very slightly curved, with proximate parallel margins.
Brain, 106:271-311. It may be caused by disease of the sensory cortex or posterior columns. People suffering from Alzheimer's disease show a reduction in stereognosis. Astereognosis can be caused by damage to the posterior association areas of the parietal, temporal, or occipital lobes, or the postcentral gyrus of either hemisphere.
Recently, increased computational resources allow inference of the posterior distribution of model parameters, which can directly be used for experiment design. proposed an approach that uses the posterior predictive distribution to assess the effect of new measurements on prediction uncertainty, while suggest maximizing the mutual information between parameters, predictions and potential new experiments.
Gobioclinus gobio has an anatomy common in Labrosomids, with a small, elongated body. The blenny has cycloid (meaning smooth to the touch) scales on the posterior body. Scales in the series 40-69 are in a lateral line, which aids in movement. Some posterior scales in the series don’t have sensory tubes.
The posterior cingulate cortex (PCC) is the caudal part of the cingulate cortex, located posterior to the anterior cingulate cortex. This is the upper part of the "limbic lobe". The cingulate cortex is made up of an area around the midline of the brain. Surrounding areas include the retrosplenial cortex and the precuneus.
The anterior section is covered by two carapace-like un-mineralized shells that are fused together. A crown-like structure formed of three concentric circular features surrounds the mouth. An antenna-form structure just posterior to the mouth may be a sensory organ. The posterior section is composed of 40 to 50 segments.
The muscles of the posterior compartment of the forearm are innervated by the radial nerve and its branches. The radial nerve arises from the posterior cord of the plexus. The somatomotor fibers of the radial nerve branch from the main radial nerve at the level of the radial groove of the humerus.
The posterior carpometacarpal ligament consists of a series of bands on the posterior surface of the carpometacarpal joints. They connect the carpal bones to the bases of the second to fifth metacarpals. The second metacarpal bone is connected to the trapezium, trapezoid, and capitate. The third metacarpal is connected to the capitate.
Schematic diagram of the human eye showing. Sub-Tenon injection is an ocular route of drug administration. It involves administration of a medication to the area between the sclera and the Tenon capsule. Posterior sub-Tenons steroid injections (PSTSI) is used in the treatment of posterior ocular inflammation, such as chronic uveitis.
Head shape is circular with posterior margin flat to feebly concave medially in full-face view. Antenna is 11-segmented with apical three segments forming a distinct club. Antennal insertion is surrounded by a raised and unbroken lamella. Frontal carina is distinct and extends just past the level of the posterior eye margin.
This area is also known as ventral posterior cingulate area 23. It is a subdivision of the cytoarchitecturally defined cingulate region of cerebral cortex. In the human it occupies most of the posterior cingulate gyrus adjacent to the corpus callosum. At the caudal extreme it is bounded approximately by the parieto- occipital sulcus.
The pectoral fin has a shallowly concave posterior margin. The first dorsal fin is moderately high with a short spine.Compagno, Dando, & Fowler, Sharks of the World, Princeton University Press, New Jersey 2005 Coloration is light grey above, paler below, with no white spots. The pale dorsal fins have dusky tips and posterior margins.
The concave occiput is tilted up, which is shown when it is aligned vertically, the snout faces downward. The supraoccipital sits anterior to the paraoccipital. The size of the basioccipital is considered to be small. The majority of the occipital surface, posterior “horn”, and posterior lateral margins are made from the squamosal.
The ciliary ganglion is a parasympathetic ganglion located just behind the eye in the posterior orbit. Three types of axons enter the ciliary ganglion but only the preganglionic parasympathetic axons synapse there. The entering axons are arranged into three roots of the ciliary ganglion, which join enter the posterior surface of the ganglion.

Tailless protein inhibits knirps gene expression in the posterior part of the embryo, allowing the knirps protein to be expressed only in the central part of the embryo (but more posterior compared to Krüppel). This is due to the ability of both hunchback and tailless to bind to the enhancer regions of knirps.
They pierce the fascia of the urogenital diaphragm, and run forward along the lateral part of the urethral triangle in company with the posterior scrotal branches of the perineal artery; they are distributed to the skin of the scrotum or labia and communicate with the perineal branch of the posterior femoral cutaneous nerve.
Vidria vespa is a proetid trilobite belonging to the family Phillipsiidae. The fossils are found in Middle Permian-aged marine strata of Western Texas. It is unique among Permian-aged trilobites in having a posterior spine emanating from the pygidium of the adult (two such posterior spines are present in immature individuals).
The posterior superior alveolar nerve of the maxillary nerve goes from the pterygopalatine fossa to the infratemporal region via this fissure. The pterygopalatine plates are separated laterally from the posterior surface of the body of the maxilla by the pterygomaxillary fissure. In older texts, the pterygomaxillary fissure is sometimes called the pterygopalatine fissure.
An autapomorphy is a distinctive anatomical feature that is unique to a given organism or group. According to Nesbitt et al. (2009) Tawa can be distinguished based on the following features: the prootic bones meet on the ventral midline of the endocranial cavity, the anterior tympanic recess is greatly enlarged on the anterior surface of the basioccipital and extends onto the prootic and the parabasisphenoid, a deep recess is present on posterodorsal base of the paroccipital process, a sharp ridge extending dorsoventrally on the middle of the posterior face of the basal tuber, an incomplete ligamental sulcus is present on the posterior side of the femoral head, a semicircular muscle scar/excavation is present on the posterior face of femoral head, a small semicircular excavation on posterior margin of medial posterior condyle of proximal tibia, a "step" is present on the ventral surface of the astragalus, metatarsal I is similar in length to the other metatarsals.

The first mandibular molar has an anterior cap merging with two open triangles, three closed triangles, and a posterior lobe.
Although this is infrequently distracting in posterior segment imaging, it can be quite confusing when imaging near the iris plane.
The rectus capitis posterior major (or rectus capitis posticus major, both being Latin for larger posterior straight muscle of the head) arises by a pointed tendon from the spinous process of the axis, and, becoming broader as it ascends, is inserted into the lateral part of the inferior nuchal line of the occipital bone and the surface of the bone immediately below the line. A soft tissue connection bridging from the rectus capitis posterior major to the cervical dura mater was described in 2011. Various clinical manifestations may be linked to this anatomical relationship. It has also been postulated that this connection serves as a monitor of dural tension along with the rectus capitis posterior minor and the obliquus capitis inferior.
The posterior surface is traversed by a shallow groove directed obliquely downward and medialward, continuous with a similar groove on the posterior surface of the talus and serving for the passage of the tendon of the Flexor hallucis longus. The lateral surface presents a triangular rough depression for the attachment of the inferior interosseous ligament connecting it with the fibula; the lower part of this depression is smooth, covered with cartilage in the fresh state, and articulates with the fibula. The surface is bounded by two prominent borders (the anterior and posterior colliculi), continuous above with the interosseous crest; they afford attachment to the anterior and posterior ligaments of the lateral malleolus. The medial surface -- see medial malleolus for details.
When an individual loses enough posterior teeth to make it difficult to chew, he or she may need to cut their food into very small pieces and learn how to make use of their anterior teeth to chew. If enough posterior teeth are missing, this will not only affect their chewing abilities, but also their occlusion; posterior teeth, in a mutually protected occlusion, help to protect the anterior teeth and the vertical dimension of occlusion and, when missing, the anterior teeth begin to bear a greater amount of force for which they are structurally prepared. Thus, loss of posterior teeth will cause the anterior teeth to splay. This can be prevented by obtaining dental prostheses, such as removable partial dentures, bridges or implant-supported crowns.
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.
C. teleta has a narrow, segmented body with reduced parapodia and is red in color. There are nine anterior thoracic segments and many more abdominal segments. New segments are added throughout the lifespan from a posterior subterminal growth zone, called the posterior growth zone. Like other polychaetes, C. teleta has fine bristles or setae.
Ossification of the posterior longitudinal ligament (OPLL) is a process of fibrosis, calcification, and ossification of the posterior longitudinal ligament of the spine, that may involve the spinal dura. Once considered a disorder unique to people of Asian heritage, it is now recognized as an uncommon disorder in a variety of patients with myelopathy.
The left valve has a single anterior lateral tooth and there are no posterior lateral teeth on either valve. The periostracum is thin and covered with a thick ferruginous deposit. This obscures the sculpture of concentric lines with a small number of faint radial lines. The anterior adductor scar is larger than the posterior one.
Two pairs of spinnerets are present: the posterior median pair being short and unsegmented, the posterior lateral pair are longer, but still short, and have three segments, the apical one being the shortest. The female spermathecae have a single lobe. The male palpal bulb has a thin embolus, and is borne on a spineless cymbium.

A lateral dislocation of the knee They may be divided into five types: anterior, posterior, lateral, medial, and rotatory. This classification is based on the movement of the tibia with respect to the femur. Anterior dislocations are the most common, followed by posterior dislocations. They may also be classified based on what ligaments are damaged.
The posterior process of the postorbital bones reached far back into the temporal arches, underneath the temporal fossae. The whole skull was highly ventrodorsally compressed. It had temporal tubercles, but they were small, and restricted solely to the posterior ends of the squamosal bones. Its occiput was deeply excavated and its entire braincase very small.
Normal fetal position (occiput anterior); back labour may occur if the fetus faces the opposite direction (occiput posterior). Back labor can be painful. Relief may be sought by trying to find a comfortable position or using a birth ball. Back labor (less commonly called posterior laborMoore, Mary Lou & Ora Strickland, Realities in Childbearing, p.

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.
A. flavissima typically have a mesoscutum (the middle thoracic segment of the insect) that is dark yellow with outstanding bristles. The gaster (the enlarged posterior of the abdomen) is pale yellow along with the humeral plate. The posterior ocelli of the species are widely separated from the eyes. In addition, the wing length is typically .
O. bursa has four pairs of legs, three of which are located on the sternal plate. Towards its posterior end, its body narrows slightly. These two features distinguish it from another member of the genus, Ornithonyssus sylviarum, whose posterior end narrows considerably and which possesses only two pairs of legs on its sternal plate.
Posterior parapodia, on the other hand, possess 4 compound chaetae each, with unidentate blades provided with short spines as well. The dorsal simple chaetae from the proventricular segments are unidentate and show marginal spines. Its ventral simple chaetae on the posterior parapodia are sigmoid, smooth and unidentate. Its acicula is bent to a right angle.
Observed in life, D. translucida is almost perfectly transparent except for its eyes. It has a distinctive pattern of melanophores. There are no melanophores on the dorsal surface except on the head over the posterior part of the brain. On the posterior half of the body, there a few melanophores following the horizontal midline.

Auturus evides is a species of flat-backed millipede in the family Euryuridae. It is found in North America. Auturus evides is dark brown with light orange spots on the posterior part of each segment. The lateral portion of each segment has a spot of the same color which widens toward the posterior end.
The cirrus is long and is 65% of seminal vesicle length. The testis is seen to be single, medial, looped, lacking lobed marginal and is found posterior to the intestine. The post ovary space comprises 1/3rd the body length. The uterus post-gonadal is found dorsal to posterior-most end of the seminal vehicle.
Brachionus nilsoni is a euryhaline (tolerates a wide range of salinity) rotifer in the Family Brachionidae. The species is distinguishable from all brachionids by lacking posterior spines, by the shape of the foot apertures and the posterior portion of its lorica, and the long thin occipital spines. It is named after Börje Carlin-Nilsson.
An article of Simon Tavaré et al. was first to propose an ABC algorithm for posterior inference. In their seminal work, inference about the genealogy of DNA sequence data was considered, and in particular the problem of deciding the posterior distribution of the time to the most recent common ancestor of the sampled individuals.
The lateral corticospinal tract (also called the crossed pyramidal tract or lateral cerebrospinal fasciculus) is the largest part of the corticospinal tract. It extends throughout the entire length of the spinal cord, and on transverse section appears as an oval area in front of the posterior column and medial to the posterior spinocerebellar tract.
The first part of the surgery should be to make an incision along the posterior border of the deltoid. The muscle is exposed to its insertion on the humerus. Next the part of the muscles that originates from the spina scapulae, the posterior one third to one half, is isolated from the anterior portion of the muscle. The insertion of the posterior deltoid is then elevated of the muscle and the distance between the mobilized deltoid tendon to the olecranon is measured to determine the length of the interposition graft needed.
The vertebrae were procoelous in the neck, back, and part of the tail, and the procoelous shape was most strongly developed in the neck vertebrae. Procoely is a type of vertebral articulation, based on the shape of the anterior and posterior faces of the vertebral centrum. In procoelous vertebrae, the vertebrae articulate with a concave leading surface and a convex posterior surface. The vertebrae of Pachycheilosuchus had a slight dimple or concavity on the posterior surface as well, making these bones different from the procoelous vertebrae that are a hallmark of derived eusuchian crocodilians.
In 1970, by means of clonal analysis, the Anterior-Posterior boundary was identified. The founder cells, found at the border between parasegments 4 and 5 of embryo, are already determined at the early blastoderm stage and defined into the two populations they will generate by stripes of the engrailed gene. The selector gene, engrailed (en), is a key determinant in boundary formation between the anterior and posterior compartments. As the wing imaginal disc expands, posterior, but not anterior cells will express engrailed and maintain this expression state as they expand and form the disc.
The sternohyoid muscle is a thin, narrow muscle attaching the hyoid bone to the sternum, one of the paired strap muscles of the infrahyoid muscles serving to depress the hyoid bone. It is innervated by the ansa cervicalis. The muscle arises from the posterior border of the medial end of the clavicle, the posterior sternoclavicular ligament, and the upper and posterior part of the manubrium sterni. Passing upward and medially, it is inserted by short tendinous fibers into the lower border of the body of the hyoid bone.
When Shh diffuses from the ZPA, it predominates in the posterior region of the limb bud, activating Gli3 in the posterior region, while the repressor is still active in the anterior region. This leads to activation of other genes such as Hox genes, FGF genes and BMP genes in the posterior region, setting up digit patterning. BMP, plays a role in limb morphology, specifically, digit positioning, but the specific regulation of BMP is unclear. 550px In particular, the Hox genes A and D are likely to be controlled by Shh within the ZPA.
Posterior open bite is caused when posterior teeth such as molars or premolars fail to touch their counterpart tooth. This is more likely to occur in segments where there may be unilateral open bite or open bite related to one or more teeth. Failure of eruption of teeth either due to primary failure or mechanical obstruction during eruption phase can cause the open bite. Sometimes lateral tongue thrust may also prevent the eruption of the posterior teeth, thus eliminating this habit maybe key to eruption in those instances.
Ulegyria can affect many parts of the brain including the cerebral cortex, parasagittal areas and posterior regions of the brain, such as the parietal and occipital lobes. These areas are situated either near artery rich regions or near a major cerebral artery. For instance, specifically in neonatal children, ulegyria-affected areas are found near the posterior cerebral artery or near the artery rich region between the middle and posterior regions of the brain, often referred to as watershed regions. Neurons affected by ulegyria exhibit properties that differ from normally functioning neurons.
The major regions involved are the left posterior ventrolateral prefrontal cortex, the left premotor cortex, and the left posterior parietal cortex. Within the ventrolateral prefrontal cortex, Broca's area is the main location responsible for verbal rehearsal and the articulatory process. The dorsal premotor cortex is used in rhythmic organization and rehearsal, and finally the posterior parietal cortex shows a role in localizing objects in space. The cortical areas in the brain believed to be involved with auditory sensory memory exhibited by mismatch negativity response have not been localized specifically.
On the one hand PAR-3, PAR-6 and aPKC (called anterior PAR proteins) occupy both plasma membrane and the cytoplasm prior to symmetry breaking. PAR-1, the C. elegans specific ring-finger-containing protein PAR-2, and LGL-1 (called posterior PAR proteins) are present mostly in the cytoplasm. The male centrosome provides a cue, which breaks an initially homogenous membrane distribution of anterior PARs by inducing cortical flows. These are thought to advect anterior PARs towards one side of the cell, allowing posterior PARs to bind to other pole (posterior).
So, during inhalation, both the posterior and anterior air sacs expand, the posterior air sacs filling with fresh inhaled air, while the anterior air sacs fill with "spent" (oxygen-poor) air that has just passed through the lungs. During exhalation the intrapulmonary bronchi were believed to be tightly constricted between the region where the ventrobronchi branch off and the region where the dorsobronchi branch off. But it is now believed that more intricate aerodynamic features have the same effect. The contracting posterior air sacs can therefore only empty into the dorsobronchi.
The centrosomes deposited by the sperm are responsible for the establishment of the posterior pole within the zygote. Sperm with mutant or absent centrosomes fail to establish a posterior pole. The establishment of this polarity initiates the polarized distribution of a group of proteins present in the zygote called the PARD proteins (partitioning defective), which are a conserved group of proteins that function in establishing cell polarity during development. These proteins are initially distributed uniformly throughout the zygote and then become polarized with the creation of the posterior pole.
The glottis is defined as the true vocal folds and the space between them. It is composed of an intermembranous portion or anterior glottis, and an intercartilaginous portion or posterior glottis. The border between the anterior and posterior glottises is defined by an imaginary line drawn across the vocal fold at the tip of the vocal process of the arytenoid cartilage. The anterior glottis is the primary structure of vocal fold vibration for phonation and the posterior glottis is the widest opening between the vocal folds for respiration.
A venous sinus (the circular sinus) surrounds the superior portion of the tuber cinereum; the circular sinus is in fact simply a portion of the two lateral cavernous sinuses, joined together by a posterior and anterior intercavernous sinus. The mammillary bodies form the floor posterior of the tuber cinereum, acting as the link between the fornix and the hypothalamus. Posterior of the mamillary bodies, the ventricle becomes the opening of the cerebral aqueduct, the inferior borders becoming the crus cerebri (sometimes historically called the cerebral peduncle) of the midbrain.
In dentistry, the term posterior teeth usually refers as a group to the premolars and molars, as distinguished from the anterior teeth, which are the incisors and canine teeth. The distinction is one of anterior (front of the body) versus posterior (rear of the body). The distinction holds in both the upper jaw (maxilla) and lower jaw (mandible). As a rough guide, it can be said that the anterior teeth are tailored to biting (breaking the food into chewable chunks) whereas the posterior teeth are tailored to chewing (comminuting the food into swallowable particles).
Any lesion occurring within or affecting the corticobulbar tract is known as an upper motor neuron lesion. Any lesion affecting the individual branches (temporal, zygomatic, buccal, mandibular and cervical) is known as a lower motor neuron lesion. Branches of the facial nerve leaving the facial motor nucleus (FMN) for the muscles do so via both left and right posterior (dorsal) and anterior (ventral) routes. In other words, this means lower motor neurons of the facial nerve can leave either from the left anterior, left posterior, right anterior or right posterior facial motor nucleus.
It is derived from their ventral rami, in spite of the fact that the latissimus dorsi is found in the back. The thoracodorsal nerve is a branch of the posterior cord of the brachial plexus, and is made up of fibres from the posterior divisions of all three trunks of the brachial plexus. It follows the course of the subscapular artery, along the posterior wall of the axilla to the Latissimus dorsi, in which it may be traced as far as the lower border of the muscle. It supplies latissimus dorsi on its deep surface.
As for most cervicals, the neural arches and spines are short, the anterior articular processes are strongly developed in that direction, and the anterior lobes of the diapophyses (bony projections to the lateral sides) extend to the bottom and lateral directions to articulate with tubercles. Seventh and eighth cervicals are the longest with long centra and posterior to them, the vertebral size slightly narrows. In most posterior cervicals, the centra are opisthocoelous with shallow posterior grooves. The dorsal vertebrae centra, unlike in the cervicals, are narrow and platycoelous with an average length of .
This area includes not only V4, but two other areas in the posterior inferior temporal cortex, anterior to area V3, the dorsal posterior inferior temporal cortex, and posterior TEO. Area V4 was initially suggested by Semir Zeki to be exclusively dedicated to color, but this is now thought to be incorrect. In particular, the presence in V4 of orientation-selective cells led to the view that V4 is involved in processing both color and form associated with color. Color processing in the extended V4 occurs in millimeter-sized color modules called globs.
Aqueous humor produced by the epithelium of the ciliary body is secreted into the posterior chamber, from which it flows through the pupil to enter the anterior chamber. The hypermature cataractous lens or,the intraocular lens (IOL) implanted after cataract surgery may obstruct the aqueous flow through the pupil. The block in flow of aqueous from the posterior to the anterior chamber will lead to a condition known as Iris bombe. In this condition, pressure in the posterior chamber rises, resulting in anterior bowing of the peripheral iris and obstruction of the trabecular meshwork.
The cytostome-cytopharynx complex functions as follows: macromolecules to be taken up by a cell enter the cytostome. Macromolecules then pass into the lumen of the cytopharynx and are transported to the posterior end of the cell where they are put into budding vesicles that are transported to others parts of the cell. The cytopharynx in this way acts much like a straw that sucks macromolecules to the posterior end of the cell. The passage of macromolecules from the entrance of the cytostome to the posterior end of the cytopharynx takes at least 2 minutes.
Since the vertebral body in a retrolisthesis moves in a posterior direction, the grading used for spondylolistheses is of little use. It is however useful to divide the anterior to posterior dimension of the intervertebral foramina (IVF) (4) into four equal units. A posterior displacement of up to ¼ of the IVF is graded as Grade 1, ¼ to ½ as Grade 2, ½ to ¾ as Grade 3, ¾ to total occlusion of the IVF as Grade 4. Alternatively, a measurement of the amount of displacement can also made by measuring the bone displacement in millimetres.
Pathological changes can be noticed as well in the posterior roots of the cord and, to lesser extent, in peripheral nerves. In the brain itself, changes are less severe: They occur as small sources of nervous fibers decay and accumulation of astrocytes, usually subcortically located, and also round hemorrhages with a torus of glial cells. MRI of the brain may show periventricular white matter abnormalities. MRI of the spinal cord may show linear hyperintensity in the posterior portion of the cervical tract of the spinal cord, with selective involvement of the posterior columns.
The posterior is where the uterus lies. In the parasite's midsection lie the vitelline glands that are involved in egg formation.
The basal half of the costal area and the subcostal, posterior area are distinctly suffused brown. The hindwings are brownish cream.
Finally, the autobiographical memory differences may be attributed to a smaller posterior hippocampal volume in any individuals going through cumulative stress.
Pre-LC neurons project heavily to the diencephalon, particularly to subregions of the midline thalamus and the posterior and lateral hypothalamus.
Anterior and posterior PAR proteins then maintain polarity until cytokinesis by mutually excluding each other from their respective cell membrane areas.
A relative past tense is sometimes called an anterior tense, while a relative future tense may be called a posterior tense.
In addition, degradation of oral debris by microorganisms produce organosulfur compounds (volatile sulphur compounds) on the posterior (rear) of the tongue.
The apex of tusk shells is the small, open posterior end, and the opening itself is usually called the apical aperture.
The posterior half of the forewings is yellow, with one or two semicircular yellow markings. The hindwings are reflective grey-fuscous.
The underlying pathology is thought to affect the posterior thalamus which is the fundamental brain structure that controls body upright posture.
End branches of the medial posterior choroidal arteries, superior thalamostriate, superior choroid veins and septal veins also pass through the foramen.
The capsule varies from 2 to 28 micrometres in thickness, being thickest near the equator and thinnest near the posterior pole.
For this reason the left, right and posterior aortic sinuses are also called left-coronary, right- coronary and non-coronary sinuses.
The furrows between the posterior pygidial segments are faint, while segmentation in the pleural region of the pygidium is barely discernable.
The fingers are weakly webbed while the toes are extensively webbed. Males have a vocal sac on the posterior throat region.
The dorsal fin free rear tips and the caudal fin posterior margin are white. The largest known specimen measures in length.
The hindwings are light yellow, becoming pale orange on the posterior one-third and bright orange on the apical one-fourth.
Mento-posterior positions cannot be delivered vaginally in most cases (unless rotated) and are candidates for Cesarean section in contemporary management.
The joint will want to subluxate posterior, but this is easily corrected with the subscapularis repair and rotator cuff interval imbrication.
The posterior median sulcus of medulla oblongata (or posterior median fissure or dorsal median sulcus) is a narrow groove; and exists only in the closed part of the medulla oblongata; it becomes gradually shallower from below upward, and finally ends about the middle of the medulla oblongata, where the central canal expands into the cavity of the fourth ventricle.
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.
Some are thought to be derived from the posterior part of the thalamus and from the superior colliculus, whereas others are believed to be continued downward into the medial longitudinal fasciculus. For the pupillary light reflex, the olivary pretectal nucleus innervates both Edinger-Westphal nuclei. To reach the contralateral Edinger-Westphal nucleus, the axons cross in the posterior commissure.
A single spiral runs between the angulation and the upper suture, and in the body whorl bounds the front of the posterior sinus. Another lies midway between the angulation and the lower suture. In the suture, the second angulation of the body whorl may appear as a sutural cord. This bounds the back of the posterior labral sinus.
Ramírez-Velasco et al. (2012) diagnosed Huehuecanauhtlus by a unique combination of characters. For example, two teeth exposed on the occlusal plane of the rostral third and the posterior third of the dentary and maxilla, respectively. It had seven sacral vertebrae and tall neural spines of posterior vertebrae, being between 3.5 and 4 times taller than their corresponding centra.
The middle segment is the mesothorax, with the major features being the second pair of legs and the anterior wings. The third and most posterior segment, abutting the abdomen, is the metathorax, which features the third pair of legs and the posterior wings. Each segment is dilineated by an intersegmental suture. Each segment has four basic regions.
In some cases of spontaneous paralysis of the nerve, releasing this fibrous band released pressure on the nerve and restored function Spinner, Morton. "The Arcade of Frohse and Its Relationship to Posterior Interosseous Nerve Paralysis." The Bone and Joint Journal 50.4 (1968): 809-12. Print. Considerably diminished in size, it descends as the posterior interosseous nerve.
The hip joint includes the articulation of the femoral head (of femur) and the acetabulum of the pelvis. In hip dislocation, the femoral head is dislodged from this socket. Posterior dislocation is the most prevalent, in which the femoral head lies posterior and superior to the acetabulum. This is most common when the femur is adducted and internally rotated.
While the whole story is unknown for neural induction, FGFs seem to play a role in mesoderm and neural induction. The anterior/posterior patterning of the embryo requires signals like cerberus from the hypoblast and the spatial regulation of retinoic acid accumulation to activate the 3' Hox genes in the posterior neuroectoderm (hindbrain and spinal cord).
RFN models identify rare and small events in the input, have a low interference between code units, have a small reconstruction error, and explain the data covariance structure. RFN learning is a generalized alternating minimization algorithm derived from the posterior regularization method which enforces non-negative and normalized posterior means. RFN were very successfully applied in bioinformatics and genetics.
This large weevil has a dark exoskeleton, covered in small hair-like coppery-brown scales. On the sides and posterior, the colouration is lighter with a prominent white streak along the centre of its thorax. It has obvious prominences on its sides and posterior. Its rostrum is as long as its thorax with a wide channel in the centre.
Sometimes (incorrectly) considered synonymous with the posterior pituitary, the pars nervosa includes Herring bodies and pituicytes. ;Infundibular stalk: Also known as the infundibulum or pituitary stalk, the infundibular stalk bridges the hypothalamic and hypophyseal systems. The median eminence is only occasionally included as part of the posterior pituitary. Other sources specifically exclude it from the pituitary.
Punctate inner choroiditis (PIC) is an inflammatory choroiditis which occurs mainly in young females. Symptoms include blurred vision and scotomas. . Gray-white or yellow lesions are mainly present in the posterior pole and are between 100 and 300 micrometres in size. PIC is one of the so-called White dot syndromes which come under the heading posterior uveitis.
Posterior to it is the posterior commissure of the labia minora and the frenulum of labia minora. The sides of the vestibule are visible as Hart's line on the inside of the inner lips. Hart's line is the outer edge of the area and marks the change from vulvar skin to the smoother transitional skin of the vulva.
Multiview videofluoroscopy is a radiographic technique to view the length and movement of the velum (soft palate) and the posterior and lateral pharyngeal (throat) walls during speech. The advantage of this technique is that the entire posterior pharyngeal wall can be visualized. Disadvantages include the following: 1. This procedure requires radiation, which is a particular concern for children. 2.
Losken A, Williams JK, Burstein FD, et al. An outcome evaluation of sphincter pharyngoplasty for management of velopharyngeal insufficiency. Plast Reconstr Surg. 2003. 112(7):1755-61 Because the distal parts (posterior tonsillar pillars, which the palatopharyngeal muscles are attached to) are sutured to the other side of the posterior wall, the pharyngeal port will become smaller.
The envelope method, often called the pocket technique, requires suturing of tissue around the prolapse, encasing it in a layer of conjunctiva. Pocket techniques are easiest for doctors to learn. Pocket methods also have anterior and posterior versions. Posterior suturing techniques are the most commonly used because they cause the least complications, with no alterations in tear production.
Additional electrodes may rarely be placed to generate other leads for specific diagnostic purposes. Right-sided precordial leads may be used to better study pathology of the right ventricle or for dextrocardia (and are denoted with an R (e.g., V5R). Posterior leads (V7 to V9) may be used to demonstrate the presence of a posterior myocardial infarction.
The anterior border is serrated. It articulates with the palatine process of maxilla. The posterior border is concave, free, and serves for the attachment of the soft palate. Its medial end is sharp and pointed, and, when united with that of the opposite bone, forms a projecting process, the posterior nasal spine for the attachment of the musculus uvulae.
The Tile classification system is based on the integrity of the posterior sacroiliac complex. In type A injuries, the sacroiliac complex is intact. The pelvic ring has a stable fracture that can be managed nonoperatively. Type B injuries are caused by either external or internal rotational forces resulting in partial disruption of the posterior sacroiliac complex.
The digestive organs include an anterior, terminal mouth, a muscular pharynx, and a posterior intestine with two lateral blind-ending branches. Each adult contains male and female reproductive organs. The reproductive organs include an anterior genital atrium, with spines, a dorsal vagina, a single ovary, and a number of testes which are posterior to the ovary.
The posterior tibial artery gives rise to the medial plantar artery, lateral plantar artery, and gives rise to the fibular artery. Often, the branch of the fibular artery is said to rise from the bifurcation of the tibial-fibular trunk and the posterior tibial artery. In addition a calcaneal branch to the medial aspect of the calcaneus.
The snout is broad, and the skull widens toward the occiput or posterior margin. Two large holes behind the eye socket called temporal fenestrae occupy most of the posterior skull. Between these fenestra is a narrow sagittal crest. In front of this crest, the skull roof bones are weakly pitted with small bumps and ridges for blood vessels.
The adult hookworms are white and about 6–10 mm long. They are generally stouter than A. braziliense. The anterior end is bent dorsally, which gives the body a characteristic "hooked" or J-shaped appearance, hence the common name hookworm. Females have a tapered narrow posterior end, while males have a feathery posterior end owing to their copulatory bursa.
Oriented cell divisions in the extending germband of Drosophila. Development 134, 3049–3054. During this process the ventral germ-band extends around the posterior end of the embryo, effectively folding over onto the dorsal side of the egg. Multiple individual cells intercalating mediolateral to the anterior-posterior axis drive the resulting global elongation of the embryo.
Wnt8 induces ventral, lateral, and posterior regions of embryonic tissue. Wnt also has inhibitors like noggin to allow for the formation of dorsal tissue. In order to aid in proper development fish have an organizer center called the Nieuwkoop center. Anterior and posterior axis formation seems to be the result of interplay of FGFs, Wnt, and retinoic acid.
Fragment released from the posterior end of an adult worm. All species of Bipalium are hermaphroditic, but Bipalium kewense has rarely been observed using sexual reproduction as a primary means of reproduction. Asexual fragmentation is the primary means of reproduction in B. kewense in temperate regions. Long specimens usually release body fragments at the posterior end by transverse fission.
The aperture is auriform, moderately large, and oblique. The posterior angle is acute, slightly channeled at the junction of the outer lip and columella. The columella is rather strong, very oblique, revolute showing only the lamellar posterior fold when the lip is complete. This fold is situated a little anterior to the insertion of the columella.
The intercondylar area is the separation between the medial and lateral condyle on the upper extremity of the tibia. The anterior and posterior cruciate ligaments and the menisci attach to the intercondylar area. The intercondyloid eminence is composed of the medial and lateral intercondylar tubercles, and divides the intercondylar area into an anterior and a posterior area.
In contrast to the posterior pre-SMA, the anterior pre-SMA is connected with most of the prefrontal but not somatomotor areas. Overall, the SMA is strongly connected to the thalamus and epithalamus, the posterior pre-SMA to putamen, pallidum, and STN and anterior pre-SMA to the caudate nucleus, with the caudate showing significant hemispheric asymmetry.
There are both external and internal ligaments joining the valves and there are no teeth on the hinge. On the inside of the valve, the posterior adductor muscle scar is large and triangular while the anterior one is long and thin. The pallial sinus is small. The valves gape at the posterior end where the two separate sinuses emerge.
It was named for French zoologist Georges Louis Duvernoy who first described the gland in 1832. The Duvernoy's gland is positioned posterior to the eye, encased in a thin cover of connective tissue, and consists mostly of serous cells. A single, short duct extends anteromedially from the lumen of the gland to the base of the posterior fangs.
Adult T. canis are found only within dogs and foxes and the males are 4–6 cm in length, with a curved posterior end. The males each have spicules and one “tubular testis.” Females can be as long as 15 cm, with the vulva stretching one third of their bodylength. The females do not curve at the posterior end.
The pulvinar varies in importance in different animals: it is virtually nonexistent in the rat, and grouped as the lateral posterior-pulvinar complex with the lateral posterior thalamic nucleus due to its small size in cats. In humans it makes up roughly 40% of the thalamus making it the largest of its nuclei.LaBerge, D. (1999). Attention pp. 44-98.
Axons from the third-order neurons in the ventral posterior nucleus in the thalamus, ascend the posterior limb of the internal capsule. Those originating from the head and the leg swap their relative positions. The axons synapse in the primary somatosensory cortex, with lower body sensation most medial (e.g., the paracentral lobule) and upper body more lateral.
Both border and border furrow of the cephalon are relatively narrow. The transglabellar furrow is straight or curved slightly towards posterior. The posterior glabellar lobe is parallel sided, has two pairs of lateral furrows and small basal lobes; there is no median node. The pygidial border is flattened and wide with posterolateral angles, but no spines.
The wings are transparent with a darkened brownish apex. The hind wings are often bluish at the base. The front wings (tegmina) are dark with clear markings. This species is rather similar to Aiolopus thalassinus from which it differs for the larger posterior femora, the transparent-blue wings and the coarse punctuation in the posterior part of the pronotum.
The posterolateral tract (fasciculus of Lissauer, Lissauer's tract, tract of Lissauer, dorsolateral fasciculus, dorsolateral tract, zone of Lissauer) is a small strand situated in relation to the tip of the posterior column close to the entrance of the posterior nerve roots. It is present throughout the spinal cord, and is most developed in the upper cervical regions.
Apart from the above neck muscles, the following muscles have also been observed contributing to respiration: serratus anterior, pectoralis major and pectoralis minor, trapezius, latissimus dorsi, erector spinae, iliocostalis, quadratus lumborum, serratus posterior superior, serratus posterior inferior, levatores costarum, transversus thoracis, subclavius (Kendall et al., 2005). The levator labii superioris alaeque nasi muscle lifts the sides of the nostrils.
Posterior sub-Tenon's Steroid Injections for the Treatment of Posterior Ocular Inflammation: Indications, Efficacy and Side Effects This route is also reported to be used to administer triamcinolone acetonide (a corticosteroid) in the treatment of macular telangiectasia type 1. Also, it is used in the ocular anesthesia (e.g. peribulbar and retrobulbar anaesthesia).Sub-Tenon anaesthesia, Eye Wiki.
There are multiple posterior percutaneous approaches, but no clinical evidence suggests that any one technique is more efficient than the rest. The posterior approaches generally utilize two needles, one at each side of the L1 vertebral body pointing towards the T12 vertebral body. Increasing the spread of the injection may increase the efficacy of the neurolysis.
Banffidae is an extinct family of vetulicolians that is the only family of the order Banffiata and class Heteromorphida, also known as Banffozoa. It contains the genera Banffia, Heteromorphus, and Skeemella. Banffids differ from vetulicolians of the class Vetulicolida in having a posterior body section with numerous segments, rather than the seven-segmented posterior body of vetulicolidans.
The adapicle part is a semicircular shape with a lower-central opening, while the posterior region has a wide, concaved curve. The sclerite that sits on top of the surface of the adapicle portion contains a simple, rugged array of 5-6 small, protruding bumps; the posterior region's sclerite carries along an alternating array of 10-14 spines.
NCBI Expression data. This microarray study RNA-seq was performed of tissue samples from 95 human individuals representing 27 different tissues in order to determine tissue-specificity of all protein- coding genes. (Embryonic anterior and posterior palate). This study indicated that the posterior palate gene level expression was much higher than that of the anterior palate.
The brain has a dual blood supply that comes from arteries at its front and back. These are called the "anterior" and "posterior" circulation respectively. The anterior circulation arises from the internal carotid arteries and supplies the front of the brain. The posterior circulation arises from the vertebral arteries, and supplies the back of the brain and brainstem.
The skin of the dorsum is shagreened and bears small, round tubercles, more prominently so on the posterior part of the body and the thighs. The coloration is bright green, with darker green or gray tubercles. The flanks and posterior surfaces of thighs are mottled with gray or brown. The venter is dull white, suffused heavily with pale gray.
Floaters are generally harmless, but the sudden onset of recurring floaters may signify a posterior vitreous detachment or other diseases of the eye. Posterior vitreous detachment: Once liquid vitreous enters the sub-hyaloid space between the vitreous cortex and the retina, it may strip the vitreous cortex off the retina with each eye movement (see Saccade).
The superficial branch enters the deep surface of the gluteus maximus, and divides into numerous branches, some of which supply the muscle and anastomose with the inferior gluteal artery, while others perforate its tendinous origin, and supply the integument covering the posterior surface of the sacrum, anastomosing with the posterior branches of the lateral sacral arteries.
The shell is broadly oval to quadrate with the umbones distinctly anterior. The posterior hinge line is straight, the posterior margin truncate, and the anterior hinge line grades into the down-sloping anterior margin. It is prominent posteriorly, where the shell is conspicuously decussate. The surface has a sculpture of fine concentric striae and bolder radiating lines.
A parapharyngeal abscess is a deep neck space abscess of the parapharyngeal space (or pharyngomaxillary space), which is lateral to the superior pharyngeal constrictor muscle and medial to the masseter muscle. This space is divided by the styloid process into anterior and posterior compartments. The posterior compartment contains the carotid artery, internal jugular vein, and many nerves.
Members of this genus have large, elongated oval shells with two equal sized valves. The anterior end is somewhat sharply curved but the posterior end is more rounded. The valves gape slightly at both ends, more so at the posterior end. The shell is fairly thick and is sculptured with fine concentric lines corresponding to periods of growth.
The female species posterior edge is distinct and U-shaped. The vigina of the sinus is funnel shaped, and is wider than the width of the doctus borsae. Their doctus seminalis is small and oval shaped, and is placed next to the posterior part of doctus borsae. The species is similar to Mompha bradleyi, Mompha confusella, and Mompha subdivisella.
The ovate shell is oblong, transverse, equilateral, inequivalve, and inflated. The beaks are small, that of the left slightly notched. The valves are white, delicate, and diaphanous, rounded upon the anterior side, truncated obliquely upon the posterior sid. The side is bounded outwardly by an obtuse angle, which extends from the beak to the lower and posterior edges.
Unlike other chroniosuchids, Madygenerpeton lacks an antorbital fontanelle in front of the eyes.The postparietal or posterior area of the skull is concave.
The frenulum of labia minora (fourchette or posterior commissure of the labia minora) is a frenulum where the labia minora meet posteriorly.
In this case, the gallbladder position is often anomalous as well – it is often located anterior to the liver, rather than posterior.
Pituicytes are glial cells of the posterior pituitary. Their main role is to assist in the storage and release of neurohypophysial hormones.
There is a marginal series of blackish elongate dots around the posterior part of the costa and termen. The hindwings are grey.
The posterior spiracles are then fully developed with three spiracular openings. The spine on the anal segment has a bell-shaped appearance.
This involves a repeated exploration combined with a posterior neurectomy. This procedure has been shown to be beneficial in 50% of cases.
Several Bayesian methods have been proposed to compute the posterior distribution of the number of cointegrating relationships and the cointegrating linear combinations.
A rusty colour appears towards the posterior end. Setae arise from black dots. Pupation occurs within a silken cell woven between leaves.
The plantar ligaments have a similar arrangement to the dorsal, and are strengthened by slips from the tendon of the tibialis posterior.
The terminology posterior is based on viewing the heart from the "Valentine" position, not by the heart's actual position in the body.
When the left circumflex supplies the posterior descending artery in those 15% of cases, it is known as a left dominant circulation.
The aperture is broadly ovate. The posterior angle is acute. The outer lip is thin. The columella is slender, curved, decidedly revolute.
The plantar ligaments have a similar arrangement to the dorsal, and are strengthened by slips from the tendon of the tibialis posterior.
Haller cells are infraorbital ethmoidal air cells lateral to the lamina papyracea. These may arise from the anterior or posterior ethmoidal sinuses.
The supraspinous ligament, along with the posterior longitudinal ligament, interspinous ligaments and ligamentum flavum, help to limit hyperflexion of the vertebral column.
The posterior lumbar aponeuroses are situated just on top of the epaxial muscles of the thorax, which are multifidus spinae and sacrospinalis.
It is perforated by the ulnar nerve, the superior ulnar collateral artery, and the posterior branch of the inferior ulnar collateral artery.
The small saphenous vein (also short saphenous vein or lesser saphenous vein), is a relatively large superficial vein of the posterior leg.
While Bayesians acknowledge the importance of likelihood for calculation, they believe that the posterior probability distribution is the proper basis for inference.
The medial orbital gyrus presents a well-marked antero-posterior sulcus, the olfactory sulcus. Its depth is an indicator of congenital anosmia.
A culdotomy or posterior colpotomy is an incision or needle puncture into this "cul-de-sac" pouch by way of the vagina.
Scales on venter imbricate, with rounded posterior edges. A single series of 5 pre-anal pores in a shallow pre-cloacal depression.
Gene expression percentiles in the posterior palate averaged approximately 75th%, while in the anterior palate, gene expression was in the 25th percentile.
The aperture is oval. The posterior angle is acute. The outer lip is thin. The inner lip is decidedly curved and reflected.
It is marked like the spire. The ovate aperture moderately large. The posterior angle is obtuse. The outer lip is evenly curved.
The outer lip is simple. The posterior sinus is shallow. The columella is lightly curved. The anterior canal is short and broad.
Valves bent rather sharply to the right at the posterior end, orange coloration of its siphons and periostracum is usually very prominent.
The greater the posterior displacement, the more significant it is for producing a dysfunctional spinal cord or even a cauda equina syndrome.
As the bird inhales, tracheal air flows through the intrapulmonary bronchi into the posterior air sacs, as well as into the dorsobronchi, but not into the ventrobronchi (Fig. 18). This is due to the bronchial architecture which directs the inhaled air away from the openings of the ventrobronchi, into the continuation of the intrapulmonary bronchus towards the dorsobronchi and posterior air sacs. From the dorsobronchi the inhaled air flows through the parabronchi (and therefore the gas exchanger) to the ventrobronchi from where the air can only escape into the expanding anterior air sacs. So, during inhalation, both the posterior and anterior air sacs expand, the posterior air sacs filling with fresh inhaled air, while the anterior air sacs fill with "spent" (oxygen-poor) air that has just passed through the lungs.
M P Snead, D R J Snead, A J Richards, J B Harrison, A V Poulson, A H C Morris, R M Sheard, J D Scott; Clinical, histological and ultrastructural studies of the posterior hyaloid membrane; "Eye", July 2002, Volume 16, Number 4, Pages 447-453. The anterior hyaloid membrane separates the front of the vitreous from the lens. Andres Bernal, Jean-Marie Parel, Fabrice Manns; Evidence for posterior zonular fiber attachment on the anterior hyaloid membrane; "Investigative Ophthalmology and Visual Science" 2006, 47, 4708-4713. Bernal et al. describe it "as a delicate structure in the form of a thin layer that runs from the pars plana to the posterior lens, where it shares its attachment with the posterior zonule via Weigert’s ligament, also known as Egger’s line".
The external surface, known as the dorsum ossis ilium, is directed backward and lateralward behind, and downward and lateralward in front. It is smooth, convex in front, deeply concave behind; bounded above by the crest, below by the upper border of the acetabulum, in front and behind by the anterior and posterior borders. This surface is crossed in an arched direction by three lines—the posterior, anterior, and inferior gluteal lines. The posterior gluteal line (superior curved line), the shortest of the three, begins at the crest, about 5 cm in front of its posterior extremity; it is at first distinctly marked, but as it passes downward to the upper part of the greater sciatic notch, where it ends, it becomes less distinct, and is often altogether lost.
The teeth in general, and particularly the posterior ones, also occupied a lot of the skull area, particularly in the palate. The auditory region is situated much higher than the palate in lateral view and curves upwards in its posterior part. In P. macfaddeni the premaxilla has an additional pair of very small alveoli, suggesting that it may have had a third pair of barely developed incisors, and their molars are distinguished by having a well-defined valley that separates the anterior and posterior lophs. The dental formula in P. romeroi is (2I/0C/3PM/3M, 1i/0c/2pm/3m) The mandible was robust and had a well-developed, long and narrow symphysis extending to the second molar, a marked foramen posterior to the third molar, and a large maseteric fossa.
Genital synus presented. Ventral and genital suckers usually not combined. Cirrus and bursa absent. Two testes located in posterior part of the body.

They are marked like the spaces between the sutures. The aperture is suboval. The posterior angle is acute. The outer lip is thin.
It is common to find more coil in the posterior region. The males also have paired spicules but lack a gubernaculum and bursa.
Through the posterior of these it receives a branch from the chorda tympani nerve which runs in the sheath of the lingual nerve.
The presence of these channels in the posterior root ganglion gives reason to believe that other sensory neurons may contain them as well.
Autobiographical memory maintenance is predominantly observed as changing patterns of activity within posterior sensory regions; more specifically, occipitotemporal regions of the right hemisphere.
Communication branch to posterior tibial artery. Perforating branch to Anterior lateral malleolar artery. A calcaneal branch to the lateral part of the calcaneus.

The lumbar nerves are the five pairs of spinal nerves emerging from the lumbar vertebrae. They are divided into posterior and anterior divisions.
The rear portion of a male's carapace is wider than it is long. Finally, the posterior plates of the carapace often flange outward.
Other ocular findings can include conjunctival and retinal vascular abnormalities and anterior/posterior spoke-like cataract. Visual reduction from these manifestations is uncommon.
Smaller arteries extend from sides and posterior end of the heart. A thin-walled sac, known as the pericardium, completely surrounds the heart.
The posterior half of the forewings is white. The hindwings are light grey. Adults are on wing from late May to early June.
The forewings are mainly brown, each having a large black triangular patch on the posterior part. The antennae and legs are yellowish-brown.
Early instars are blood red with honey yellow at the anterior and posterior, the red fading and the body becoming greener with growth.
The internal obturator muscle is also innervated by the nerve to internal obturator (L5, S1). Muscles of the gluteal and posterior femoral regions.
The plantar cuboideonavicular ligaments have a similar arrangement to the dorsal, and are strengthened by slips from the tendon of the tibialis posterior.
It is derived from spinal nerves L4 to S3. It contains fibers from both the anterior and posterior divisions of the lumbosacral plexus.
The anterior and posterior intercostal membranes are aponeuroses located between the ribs and are continuations of the external and internal intercostal muscles, respectively.
Before hatching, larvae move the body and lower jaw against the inner wall of the egg until they break through the posterior section.
The posterior ethmoidal artery is an artery of the head which supplies the nasal septum. It is smaller than the anterior ethmoidal artery.
Although the anterior leaflet takes up a larger part of the ring and rises higher, the posterior leaflet has a larger surface area.
The release of pituitary hormones by both the anterior and posterior lobes is under the control of the hypothalamus, albeit in different ways.
Phasmids slightly posterior to mid-tail. Male is extremely rare, not essential for reproduction. Similar to female except for sexual dimorphism. Spicules slender.
The hindwings are dark fuscous, darker and somewhat coppery tinged on the posterior half.Transactions of the Entomological Society of London. 1894 (1): 18.
The term sclerotome, distinct from dermatome for anterior rami involvement, has been proposed to describe the pattern of pain produced from posterior rami.
The lateral sacral arteries arise from the posterior division of the internal iliac artery; there are usually two, a superior and an inferior.
It can be caused by a lesion at any point in the urinary tract. Causes include urolithiasis, posterior urethral valves and ureteral herniation.
In front, they are continuous with the periphery of the iris. Their posterior surfaces are connected with the suspensory ligament of the lens.
The hypostomal sclerite is not fused with any others and has anterior rami—particular branches—that are wider than on its posterior side.
The sutures are moderately impressed. The aperture is large, slightly effuse anteriorly. The posterior angle is acute. The outer lip is very thin.
The Daka calvaria temporal squamae measure at approximately 5.7mm thick centrally. The posterior temporal is approximately 10.6mm thick adjacent to the occipitomastoid suture.
There is 1 anterior temporal, and there are 2 posterior temporals.Boulenger, G.A. (1896). Catalogue of the Snakes in the British Museum (Natural History).
Damage to the glossopharyngeal nerve can result in loss of taste sensation to the posterior one third of the tongue, and impaired swallowing.
The former usually anastomosed with the sulcal branch of RCA while the later extended downwards on the posterior surface of the left ventricle.
The knife is drawn from a point just posterior to the lateral fin nearly to the tail, then curvingly around to the belly.
Normal antero-posterior (AP) radiographs are useful to look for Segond fractures and fibular head avulsion fractures. Bilateral varus stress AP radiographs comparing the injured leg to the normal side are useful in assessing the lateral joint space for opening after a potential injury. More than a 2.7 mm increase between sides indicates a fibular collateral ligament tear, while greater than 4.0 mm indicates with a grade III posterolateral knee injury. Posterior stress radiographs taken with the patient kneeling show the amount of posterior tibial translation in both knees and are helpful to diagnose PCL insufficiency and combined injuries.
The saphenous nerve from the femoral nerve provides sensory innervation to the medial side of the foot as well as the medial side of the leg. Likewise, the sural nerve provides sensory innervation to the skin on the lateral side of the foot as well as the skin on the posterior aspect of the lower leg. The tibial nerve from the sciatic nerve provides sensory innervation to the skin of the sole and toes, and the dorsal aspect of the toes. It provides motor innervation to plantaris, tibialis posterior, flexor hallucis longus, flexor digitorum longus as well as posterior muscles in the leg.
The maxilla is fairly typical in shape, with a short anterior process (front branch), a slanted dorsal process (upper branch), a long posterior process (rear branch), and an antorbital fenestra defined between the dorsal and posterior processes. The anterior process has a notch at its front tip followed by a pit, as with a few other archosauromorphs. The dorsal and posterior processes both taper rearwards like other early archosauriforms, and there may be a subtle antorbital fossa (depressed area) in front of the antorbital fenestra. The inner surface of the maxilla has an arched ledge overlooking broad interdental plates.
Similar to the flexor hallucis longus and tibialis posterior muscles, the flexor digitorum longus muscle functions to plantar flex and invert the foot. The flexor digitorum longus muscle is responsible for the movement and curling of the second, third, fourth and fifth toes. This muscle makes it possible for the toes to grip the surface of floors, which is important when it comes to maintaining postural balance on surfaces that are rough or uneven. The other deep muscles are the flexor hallucis longus and tibialis posterior; the tibialis posterior is the most powerful of these deep muscles.
ZPA mouse, right forelimb In 1968, Saunders and Gasseling did transplantation studies using tissue from chick limb bud. Removing cells from the posterior region of the limb, they transplanted them to the anterior region and noticed that extra digits formed in the anterior area and these digits were mirror images to the normal ones. This posterior mesenchyme was the ZPA, which is now known to express the protein sonic hedgehog (Shh). One hypothesis is that at high concentrations, this unknown morphogen causes mesenchyme to form on the posterior side, while low concentrations induces meshenchyme to form on the anterior end.
Its inner end is closed, by the tympanic membrane which originates from the tympanic sulcus; the upper limit of its outer orifice is formed by the posterior root of the zygomatic process, immediately below which there is sometimes seen a small spine, the suprameatal spine, situated at the upper and posterior part of the orifice. The auditory bulla (pl. bullae) is a hollow bony structure on the ventral, posterior portion of the skull that encloses parts of the middle and inner ear. In most species, it is formed by the tympanic part of the temporal bone.
The Polonaise Movement is key for the formation of the primitive streak. Cells overlaying Koller's Sickle in the posterior end of the chick embryo move towards the midline, meet and change direction towards the center of the epiblast. Cells from the lateral posterior marginal zone replace those cells that left Koller's Sickle by meeting at the center of this region, changing direction and extending anteriorly. As these cells move and concentrate at the posterior end of the embryo, the streak undergoes a single- to multi-layered epithelial sheet transition that makes it a macroscopically visible structure.
The fibular artery arises from the bifurcation of tibial- fibular trunk into the fibular and posterior tibial arteries in the upper part of the leg proper, just below the knee. It runs towards the foot in the deep posterior compartment of the leg, just medial to the fibula. It supplies a perforating branch to both the lateral and anterior compartments of the leg; it also provides a nutrient artery to the fibula. Some sources claim that the fibular artery arises directly from the posterior tibial artery, but vascular and plastic surgeons note the clinical significance of the tibial-fibular trunk.
The digestive organs include an anterior, terminal mouth, a pharynx nearly circular in outline, a short oesophagus and a posterior intestine with two lateral branches hidden in large part by the vitellaria and do not extend in the haptor. Each adult contains male and female reproductive organs. The reproductive organs include an anterior spacious genital atrium , armed with numerous somewhat conical spines, a medio-dorsal vagina, a single ovary and 14-24 testes that extend from the posterior edge of the ovary to a point a little in front of the posterior end of the vitellaria.
Auricular prominence: in the occipital area, behind the pinna, a protruding mastoid process is a proximate cause of bat ears. The soft tissues of the ear: the anatomic location of the posterior muscle of the ear (auricularis posterior) in relation to the pinna. Otoplasty: The cranial surface cartilage of the right ear; the ponticulus (ctr rt.) and the cauda helicis (right) also can be proximate causes of prominent ears. The soft tissues of the right ear: the three muscles that serve the pinna (external ear) the auricularis posterior (left), the auricularis superior (above), and the auricularis anterior (right) as considered for otoplasty correction.
To understand how posterior cruciate ligament injury can occur, one must consider the anatomical and physiological properties of the PCL. The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement. It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface. In this medial view of the extended knee, the lateral femoral condyle has been removed to reveal the structure of the PCL.
Huelsenbeck and Bollback first proposed a hierarchical Bayes method to ancestral reconstruction by using Markov chain Monte Carlo (MCMC) methods to sample ancestral sequences from this joint posterior distribution. A similar approach was also used to reconstruct the evolution of symbiosis with algae in fungal species (lichenization). For example, the Metropolis-Hastings algorithm for MCMC explores the joint posterior distribution by accepting or rejecting parameter assignments on the basis of the ratio of posterior probabilities. Put simply, the empirical Bayes approach calculates the probabilities of various ancestral states for a specific tree and model of evolution.
The risk of either occurring is around one in 100. It is unclear whether NSAIDs or corticosteroids are superior at reducing postoperative inflammation. Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'. Growth of natural lens cells remaining after the natural lens was removed may be the cause, and the younger the patient, the greater the chance of this occurring.
There are four series of suckers on the dactylus arranged in 27 transverse rows with the dorsal suckers being smaller than those in more ventral sitings. There is a carpal locking apparatus which has 1 or 2 low knobs, no smooth- ringed suckers; this apparatus is rather indistinct in some individuals. Photophores are distributed in a similar way to O. antillarum, i.e. there are three visceral photophores, an oval, anal photophore, a posterior intestinal photophore and an elongated posterior visceral photophore which forms a strip of pinkish bioluminescent tissue extending from the small photophore to the posterior tip of the mantle cavity.
More specifically, the damage was in a part of the nerve tract called the arcuate fasciculus, for which the mechanism of action is unknown, though it is known to connect the posterior (back) of the brain to the anterior (front) and vice versa. While anomic aphasia is associated with lesions throughout the left hemisphere, severe and isolated anomia has been considered a sign of deep temporal lobe or lateral temporo-occipital damage. Damage to these areas is seen in patients showing infarction limited to regions supplied by the dominant posterior cerebral artery (PCA) and is referred to as Posterior Cerebral Artery Disease.
Colporrhaphy (also vaginal wall repair, anterior and/or posterior colporrhaphy, anterior and/or posterior vaginal wall repair, or simply A/P repair or A&P; repair) is a surgical procedure in humans that repairs a defect in the wall of the vagina. It is the surgical intervention for both cystocele (protrusion of the urinary bladder into the vagina) and rectocele (protrusion of the rectum into the vagina).Encyclopedia of Surgery The repair may be to either or both of the anterior (front) or posterior (rear) vaginal walls, thus the origin of some of its alternative names.
The elongate-conic shell has a wax yellow color, with two yellowish-brown spiral bands The posterior one of which encircles the turns a little above the periphery, while the anterior one, which is a little wider, is immediately posterior to it, the two being separated by a space about as wide as the posterior band. Its length attains 8.5 mm. The whorls of the protoconch are decollated in the type specimen. The 8½ remaining whorls of the teleoconch are very slightly rounded, moderately contracted at the periphery, and closely appressed to the preceding turn at the summit.
Mandibular anterior calculus In dentistry, the term anterior teeth usually refers as a group to the incisors and canine teeth as distinguished from the posterior teeth, which are the premolars and molars. The distinction is one of anterior (front of the body) versus posterior (rear of the body). The distinction holds in both the upper jaw (maxilla) and lower jaw (mandible). As a rough guide, it can be said that the anterior teeth are tailored to biting (breaking the food into chewable chunks) whereas the posterior teeth are tailored to chewing (comminuting the food into swallowable particles).
The posterior longitudinal ligament is situated within the vertebral canal, and extends along the posterior surfaces of the bodies of the vertebrae, from the body of the axis, where it is continuous with the tectorial membrane of atlanto-axial joint, to the sacrum. The ligament is thicker in the thoracic than in the cervical and lumbar regions. In the thoracic and lumbar regions, it presents a series of dentations with intervening concave margins. The posterior longitudinal ligament is narrow at the vertebral bodies, where it covers the basivertebral veins, and widens at the intervertebral disc space.
Common causes of injuries are direct blows to the flexed knee, such as the knee hitting the dashboard in a car accident or falling hard on the knee, both instances displacing the tibia posterior to the femur. An additional test of posterior cruciate ligament injury is the posterior sag test, where, in contrast to the drawer test, no active force is applied. Rather, the person lies supine with the leg held by another person so that the hip is flexed to 90 degrees and the knee 90 degrees.Posterior Sag Test From The University of West Alabama, Athletic Training & Sports Medicine Center.
It begins on the side and vertex of the skull in a network () which communicates with the frontal vein and supraorbital vein, with the corresponding vein of the opposite side, and with the posterior auricular vein and occipital vein. From this network frontal and parietal branches arise, and join above the zygomatic arch to form the trunk of the vein, which is joined by the middle temporal vein emerging from the temporalis muscle. It then crosses the posterior root of the zygomatic arch, enters the substance of the parotid gland, and unites with the internal maxillary vein to form the posterior facial vein.
The middle third of the volar border is indistinct and rounded. The lower fourth is prominent, and gives insertion to the pronator quadratus muscle, and attachment to the dorsal carpal ligament; it ends in a small tubercle, into which the tendon of the brachioradialis muscle is inserted. The dorsal border (margo dorsalis; posterior border) begins above at the back of the neck, and ends below at the posterior part of the base of the styloid process; it separates the posterior from the lateral surface. is indistinct above and below, but well-marked in the middle third of the bone.
The condylar canal (or condyloid canal) is a canal in the condyloid fossa of the lateral parts of occipital bone behind the occipital condyle. Resection of the rectus capitis posterior major and minor muscles reveals the bony recess leading to the condylar canal, which is situated posterior and lateral to the occipital condyle. It is immediately superior to the extradural vertebral artery, which makes a loop above the posterior C1 ring to enter the foramen magnum. The anteriomedial wall of the condylar canal thickens to join the foramen magnum rim and connect to the occipital condyle.
A gradually attenuated streak is found from the middle of the fold to the blue discal portion of the posterior line and there is a short line along the apical portion of the fold, and an arrowhead above it terminated by the posterior line. The apical area beyond the posterior line is tawny fuscous on the costa with three very short whitish marks before the apex, the last limiting a round black apical dot preceded by a pale metallic-blue dot. The hindwings are grey with a blackish apical dot surrounded by whitish suffusion.Meyrick, Edward (1916–1923).
Anterior () describes what is in front, and posterior () describes what is to the back of something. For example, in a dog the nose is anterior to the eyes and the tail is considered the most posterior part; in many fish the gill openings are posterior to the eyes but anterior to the tail. In projectional radiography terminology, an anteroposterior (AP) projection is taken with the X-ray generator anteriorly (such as in the front of a human), and the X-ray detector posteriorly. In contrast, a posteroanterior (PA) projection is taken with the X-ray generator posteriorly.
The ZPA secretes shh protein, which induces formation of the distal segment of the limb, or autopod, with its posterior side facing the ZPA. When ZPA cells, non-ZPA cells made to express shh, or simply shh protein-soaked beads are implanted in the anterior side of a limb bud, the end of the resulting limb is duplicated, as in diplopodia. The posterior autopod on that limb has the normal orientation, and the extra, anterior autopod has a reversed anterior-posterior axis. This is because the original ZPA and the added source of shh signaling each induce the formation of an autopod.
The actinotroch larva is transparent and has a ring of ciliated tentacles just behind the mouth, a straight gut and an anus at the posterior end. Metamorphosis is very rapid and in the course of half an hour, new tentacles appear and the body is transformed. The metasomal sac protrudes from the ventral surface and turns inside out, with the posterior end of the worm uniting with the anterior end while the previous ventral region becomes the new posterior end. In the process, the gut is bent double into the U-shape typical of this phylum.
Anterior and posterior dorsal vertebrae from AMNH FARB 30680-30683) The vertebral column is represented by four cervical, ten dorsal, seven sacral and thirty three caudal vertebrae of several specimens. The vertebrae are mostly similar to those of other hadrosauroids but some traits can be noted. The cervical vertebrae of specimens AMNH FARB 30671-30673 have centra that are opisthocoelous (concave on their posterior sides), heart-shaped in a posterior view and flattened on the inner side. The centra of the anterior dorsals in AMNH FARB 30674-3068 appear to be less opisthocoelous but they also have heart-shaped facets.
The lateral cutaneous branch of the second intercostal nerve does not divide, like the others, into an anterior and a posterior branch; it is named the intercostobrachial nerve. It pierces the Intercostalis externus and the Serratus anterior, crosses the axilla to the medial side of the arm, and joins with a filament from the medial brachial cutaneous nerve. It then pierces the fascia, and supplies the skin of the upper half of the medial and posterior part of the arm, communicating with the posterior brachial cutaneous branch of the radial nerve. It is often the source of referred cardiac pain.
It is separated from the subarachnoid space by the diaphragma sella, therefore the arachnoid mater and thus cerebral spinal fluid cannot enter the sella turcica. The pituitary gland is divided into two lobes, the anterior lobe (which accounts for two thirds of the volume of the gland), and the posterior lobe (one third of the volume) separated by the pars intermedia. The posterior lobe (the neural lobe or neurohypophysis) of the pituitary gland is not, despite its name, a true gland. The posterior lobe contains axons of neurons that extend from the hypothalamus to which it is connected via the pituitary stalk.
A long terminal lappet is present, and is armed with two pairs of hooks. There are also two buccal suckers at the anterior extremity. The digestive organs include an anterior mouth, a pharynx larger than buccal suckers, a long wide oesophagus without diverticula and a posterior intestine that bifurcates in two lateral branches. The intestinal branches are provided with medial and lateral diverticula, joined in posterior part of opisthaptor and extending as a single branch with short diverticula to level of most posterior clamps, or not joined and one branch terminate some distance in front of the other.
Vacuoles are demonstrated in the posterior parts of the cornea. The vesicles are located on the endothelial surface. The corneal endothelium is normally a single layer of cells that lose their mitotic potential after development is complete. In posterior polymorphous corneal dystrophy, the endothelium is often multilayered and has several other characteristics of an epithelium, including the presence of desmosomes, tonofilaments, and microvilli.
Positron emission tomography (PET) scans found increased blood flow to the secondary sensory cortex, posterior parietal cortex, premotor cortex, and the superior temporal cortex. The pattern of activation, however, was with less spatial extent. Some parts of the brain were less activated than normal patients during noxious stimulus processing. These were the posterior cingulate, medial prefrontal cortex, and the occipital cortex.
Therefore, Fridén studied the architectural properties of the deltoid and triceps muscle in cadavers and concluded that the posterior deltoid would be a very suitable transfer to provide elbow extension. Since the tendon of the triceps is not long enough to reach the posterior deltoid muscle, an interposition graft is needed. Different procedures have been described to achieve the transfer.
FEMALE The fastigium is concave with upraised margins and bumps laterally on posterior margin. Posterior margin of pronotum sinuate with broad indent medially, sometimes with small v within the broad indentation (Bigelow, 1967). The character differentiating S. minutus from S. childi is the absence of a second pronotum suculus. MALE Genitalia: principal lobes of lophi tongue- shaped, Mesal lobes very round projecting medially.
In biological, but not cultural, transmissions the carriers (also known as vectors) may include other species. The two main biological modes of transmission are anterior station and posterior station. In anterior station, transmission occurs via the bite of an infected organism (the vector), like in malaria, dengue fever, and bubonic plague. Posterior station is transmission via contact with infected feces.
In the temporal bone, in the portion beneath the falciform crest are three sets of foramina; one group, just below the posterior part of the crest, situated in the area cribrosa media, consists of several small openings for the nerves to the saccule; below and behind this area is the foramen singulare, or opening for the nerve to the posterior semicircular canal.
To prevent anastomosis over-constriction, the 2 stay-sutures should also be tied. This marks the completion of the posterior wall anastomosis. # Suturing of the anterior wall of the anastomosis is achieved similarly to the posterior wall. Continuation of the 2 continuous sutures from each of their corners results in both sutures meeting at the middle anterior portion of the anastomosis.
496Grant, J. & Basmajian J., 1965, Grant's Method of Anatomy, 7th ed., The Williams & Wilkins Company, Baltimore, pp. 163-164 Some sources consider it to be part of the posterior compartment of the arm, while others consider it part of the posterior compartment of the forearm. The anconeus muscle can easily be palpated just lateral to the olecranon process of the ulna.
Gaab, Keenan & Schlaug (2003) found a difference between males and females in the processing and subsequent memory for pitch using fMRI. More specifically, males showed more lateralized activity in the anterior and posterior perisylvin regions with greater activation in the left. Males also had more cerebellar activation than females did. However, females showed more posterior cingulate and retrosplenial cortex activation than did males.
The most common complications of the posterior pharyngeal wall flap are hyponasality, nasal obstruction, snoring, and sleep apnea. Rarer complications include flap separation, sinusitis, postoperative bleeding, and aspiration pneumonia. Possible complications of the sphincter pharyngoplasty are snoring, nasal obstruction, difficulty blowing the nose. Some researches suggest that sphincter pharyngoplasty introduces less hyponasality and obstructive sleep symptoms than the posterior pharyngeal wall flap.
In the Malagasy region, this medium-sized Pheidole is easily distinguished from the teneriffana group and other species revised here by minor workers that combine a distinct promesonotal posterior process with a convex postpetiolar ventral process and major workers that combine the distinct promesonotal posterior process with a more elongate head shape and posterolateral lobes that are not rugose or reticulate.
This flap can be used for various defects in the head and neck area. Based on the dominant blood supply there are three different variations of the PMF: superior, posterior or inferior based. Only the superior and posterior based PMF is suitable for oral and facial reconstruction. The thin, quadrangular shaped, and paired platysma muscles lie in the superficial fascia of the neck.
This species grows to an average size of 10 mm and individual reaching a size of 23mm was ever recorded (the holotype one). The shell is extremely thin, outline of aperture oval, anterior broader than posterior, margin of aperture not in one plane. Periostracum light to dark greenish-brown, tightly adhering, enveloping shell edge. Shell interior lacking thickened transverse ridge at posterior.
Another type of specification is syncytial specification, characteristic of most insect classes. Specification in sea urchins uses both autonomous and conditional mechanisms to determine the anterior/posterior axis. The anterior/posterior axis lies along the animal/vegetal axis set up during cleavage. The micromeres induce the nearby tissue to become endoderm while the animal cells are specified to become ectoderm.
The posterior margin is yellowish white at the base. The antemedian line is yellowish white and straight, its posterior half is tinged with black on the inside and ocherous yellow on the outside. The postmedian and subterminal lines are greyish white, slightly sinuate and nearly parallel. The cilia is rosy mixed with greyish brown, with a fine yellowish-white basal line.
There is usually an area of localized tenderness on or near the bone and generalized swelling in the area. Percussion or palpation to the bone may reproduce symptoms and reveal crepitus in well-developed stress fractures. Anterior tibial stress fractures elicit focal tenderness on the anterior tibial crest, while posterior medial stress fractures can be tender at the posterior tibial border.
Collier's sign (also known as Collier's tucked lid sign or posterior fossa stare) is bilateral or unilateral eyelid retraction. It is an accepted medical sign of a midbrain lesion, first described in 1927 by J Collier.J. Collier, Nuclear Ophthalmoplegia with special reference to retraction of the lids and ptosis and to lesions of the posterior commissure. Brain (journal) 1927; 50; 488 - 498.
The Acanthocephala are dioecious (an individual organism is either male or female). There is a structure called the genital ligament which runs from the posterior end of the proboscis sheath to the posterior end of the body. In the male, two testes lie on either side of this. Each opens in a vas deferens which bears three diverticula or vesiculae seminales.
Both sides bent downwards and the posterior border was rounded. This segment measured approximately 1.1 cm (0.4 in) in length and 1.9 cm (0.7 in) in width. The telson was flat and trapezoidal, with the posterior edge being concave, although this may be due to poor preservation. It measured 1.3 cm (0.5 in) long and 2 cm (0.8 in) wide.
The base, apical area and two broad fascia at one-third and two-thirds are dark brown and there is a distinct black spot in the middle of the wing posterior to the fascia at one- third. A cream-yellow fascia is found posterior to the fascia at two-thirds. The hindwings are grey. Adults are on wing from late July to August.
Benton, M. J. (1990). The Species of Rhynchosaurus, A Rhynchosaur (Reptilia, Diapsida) from the Middle Triassic of England. Philosophical Transactions of the Royal Society B: Biological Sciences, 328(1247), 213-306. doi:10.1098/rstb.1990.0114 Hyperodapedon had a longitudinal stapedial canal on the posterior side of the spatulate paroccipital process which the lagenar crest extended laterally to limit the posterior end.
The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body. It contains the ciliary muscle, vessels, and fibrous connective tissue. Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber. The aqueous humor then flows through the pupil into the anterior chamber.
Its anterior border projects as the posterior obturator tubercle. From its posterior border there extends backward a thin and pointed triangular eminence, more or less elongated in different subjects, the ischial spine, origin of the gemellus superior muscle. Above the spine is a large notch, the greater sciatic notch; Below the spine is a smaller notch, the lesser sciatic notch.
The posterior lobe lacks a spine. The occipital ring has been squeezed aside into two basal lateral lobes. The border is convex, moderately wide, more so in front of the glabella and extends back to back of glabella in some species. The axis of the pygidium is conical, has seven or eight rings, and may or may not reach posterior border furrow.
The ventral surface is scaly. The posterior margin of the merus of the fifth pereopod has a strong subdistal spine. The posterior margin of the pleopods are denticulate, with an oval dactyl. The colour of the carapace is greenish- brown except for the margins and embossed granules which are paler in colour while the interior margins of the limbs are mustard coloured.
The dorsal surface and basal portions of pelvic fins have brown spots on a light brown background. Three brown streaks are noted on the posterior distal pectoral fins. Ventral surface is pale brown, with no variation noted. Dorsal areas are covered in dermal denticles except for two symmetric patches on the disc and along the posterior margin of the pectoral and pelvic fins.
Generalized filtering furnishes posterior densities over hidden states (and parameters) generating observed data using a generalized gradient descent on variational free energy, under the Laplace assumption. Unlike classical (e.g. Kalman-Bucy or particle) filtering, generalized filtering eschews Markovian assumptions about random fluctuations. Furthermore, it operates online, assimilating data to approximate the posterior density over unknown quantities, without the need for a backward pass.
Additionally, there is a distinct ridge on the posterior surface of each dorsal eminence. Dorsal eminences are small projections on the surfaces of paramedian scutes that line the back of the animal on either side of the vertebral column. In Sierritasuchus, the dorsal eminence touches the posterior margin of the paramedian scute. Each paramedian scute is covered in a random pattern of pits.
Endothelial keratoplasty (EK) has been introduced by Melles et al. in 1998. Today there are three forms of EK. Deep Lamellar Endothelial Keratoplasty (DLEK) in which the posterior part of the recipient cornea is replaced by donor tissue. Descemet's Stripping (Automated) Endothelial Keratoplasty (DSEK/DSAEK) in which the diseased Descemet's membrane is removed and replaced by a healthy donor posterior transplant.
The interorbital crests are narrow, relatively sharp-edged, non-porous and are widely separated. They run relatively parallel throughout most of their length, as far posterior as the level of the coronal crests. Posterior to that level they flare laterally to join the postorbital crests, delimiting the anterolateral edge of the postcoronal plane. Postcoronal plane is clearly defined and sloped posteroventrally.
These SAR muscles can be further divided into anterior (SARA) and posterior (SARP). The first muscle to be activated is the SARA, which is located near the back of the head. The SARA remains active until the tongue makes contact with the prey. Next, the posterior SARP, located further back on the medial and lateral sides of the salamander is activated.
Barolineocerus is long. The head is yellow to white with brown margins on the face. The pronotum is yellowish white in the middle bordered with white and a thick black line on the posterior margin with the remainder of the pronotum being brown. The wings are yellow to yellow green with white borders and a thick black line on the posterior border.
Usually the posterior most pair has the larger globular structure, although exceptions have been observed. All lateral appendages are slightly ramified and whitish at the tip. There are three principal tripinnate branchial leaves, which do not form a complete circle around the anus. The posterior portion of the foot forms a well- developed keel that has a small crest tipped with white.
The dorsal trigeminal tract, dorsal trigeminothalamic tract, or posterior trigeminothalamic tract, is composed of second-order neuronal axons. These fibers carry sensory information about discriminative touch and conscious proprioception in the oral cavity from the principal (chief sensory) nucleus of the trigeminal nerve to the ventral posteromedial (VPM) nucleus of the thalamus. The dorsal trigeminothalamic tract is also called the posterior trigeminal lemniscus.
The lobed stingaree has a rounded pectoral fin disc much wider than long, with nearly straight leading margins. The snout is fleshy and forms an obtuse angle; the tip may protrude slightly past the disc. The medium-sized eyes are followed by teardrop-shaped spiracles, which have a rounded posterior margin. The outer posterior corner of each nostril forms a visible lobe.
Otto's younger brother Henry also claimed the throne, contrary to his father's wishes. According to her biography, Vita Mathildis reginae posterior, their mother had favored Henry as king: in contrast to Otto, Henry had been "born in the purple" during his father's reign and shared his name.Vita Mathildis reginae posterior, chapter 9. Otto also faced internal opposition from various local aristocrats.
The ground color of the forewings is whitish, covered by irregular, dark brownish longitudinal streaks and spots. The posterior half before the middle and the terminal area is paler. There are two spots near the base of the posterior half, the inner one very small and the outer one distinct. The hindwing ground colour are whitish basally, becoming brownish at the apical area.
These are the retroperitoneal lymph sac, the cysterna chyli, and paired posterior lymph sacs. The posterior lymph sacs are associated with the junctions of the external and internal iliac veins. These four new lymph sacs function in the collection of lymph from the trunk and lower extremities of the body. The cysterna chyli drains into a pair of thoracic lymphatic ducts initially.
The posterior cruciate ligament (PCL) is a ligament in each knee of humans and various other animals. It works as a counterpart to the anterior cruciate ligament (ACL). It connects the posterior intercondylar area of the tibia to the medial condyle of the femur. This configuration allows the PCL to resist forces pushing the tibia posteriorly relative to the femur.
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.
This species is dimorphic with the males being ovate and the females being less compressed laterally and with the posterior end truncated and sometimes with a notch on the posterior margin. Villosa arkansasensis shows great similarity in general appearance to Obovaria jacksoniana. However, its shell morphology and life cycle are different, as are the species of host fish with which it is associated.
The zoospores are 1.2-1.8 micrometers in diameter and possess two flagellae — an anterior (transverse) one and a shorter posterior one. They also possess alveoli, a refractile body, a mitochondrion with tubular cristae, micronemes, rhoptries and a pseudoconoid. They also have a heteromorphic pair of central microtubules in the anterior axoneme. The micronemes have bulbous posterior ends and are associated with the pseudoconoid.
Probalign is a sequence alignment tool that calculates a maximum expected accuracy alignment using partition function posterior probabilities.U. Roshan and D. R. Livesay, Probalign: multiple sequence alignment using partition function posterior probabilities, Bioinformatics, 22(22):2715-21, 2006 (PDF) Base pair probabilities are estimated using an estimate similar to Boltzmann distribution. The partition function is calculated using a dynamic programming approach.
The elytra bear parallel longitudinal grooves, are mainly smooth but pubescent at their rear end and sides, and are sloping downward at their posterior end. Platypus apicalis exhibits sexual dimorphism. The elytrae of males bear tooth like projections at their posterior end. The body of females is more pubescent than this of males, lack elytral teeth, and have a more rounded shape.
The blackfin grenadier has two dorsal spines and between 25 and 39 dorsal rays. It has a large head, large eyes, and a pointed snout. The body tapers into a posterior point starting behind the first dorsal fin. The scales of the blackfin grenadier are covered in fine, conical spinules except on the posterior and ventral parts of the trunk and tail.
Dead arm syndrome starts with repetitive motion and forces on the posterior capsule of the shoulder. The posterior capsule is a band of fibrous tissue that interconnects with tendons of the rotator cuff of the shoulder. Four muscles and their tendons make up the rotator cuff. They cover the outside of the shoulder to hold, protect and move the joint.
The tricuspid valve usually has three leaflets, named the anterior, posterior, and septal leaflets. Each leaflet is connected via chordae tendineae to the anterior, posterior, and septal papillary muscles of the right ventricle, respectively. Tricuspid valves may also occur with two or four leaflets; the number may change over a lifetime.Richard Van Pragh: Cardiac anatomy in A. C. Chang et al.
Because the attachment of mylohyoid (the mylohoid line) becomes more superior towards the posterior of the mandible, posterior infected teeth are more likely to drain into the submandibular space, and infected anterior teeth are more likely to drain into the sublingual space, since the apices of the teeth are more likely to be below and above the mylohoid line respectively (see diagram).
Despite the multitude of specimens present in the bone bed that was examined, only a single pathology has been recorded in A. madagaskarensis. Specimen UA 7-16-99-620, one of the three preserved interclavicles, had been malformed so that the long posterior process had been sharply bent to the right, compared to the normal straight posterior processes of the other two interclavicles.
The temporal branch travels out from the left and right posterior components. The inferior four branches do so via the left and right anterior components. The left and right branches supply their respective sides of the face (ipsilateral innervation). Accordingly, the posterior components receive motor input from both hemispheres of the cerebral cortex (bilaterally), whereas the anterior components receive strictly contralateral input.
'Linear occlusal concept' was introduced by Frush in 1967. In this, the mesiodistal ridge of the lower posterior teeth contacted the upper posterior teeth with flat occlusal surface in order to achieve balanced occlusion. He relied on the intraoral corrections to obtain balanced occlusion. Again, his main goal was to eliminate deflective occlusal contacts and therefore increase stability of the prostheses.
Size of Bagaraatan ostromi compared to a human Posterior part of left mandible of Bagaraatan ostromi, stereophotographs in lateral, posterior, dorsal, and medial views Holtz classified Bagaraatan as a basal tyrannosauroid, Coria identified it as a troodontid, and Rauhut placed it in Maniraptora.O. W. M. Rauhut (2003). The interrelationships and evolution of basal theropod dinosaurs. Special Papers in Palaeontology 69: 1-213.
For angle and posterior body fractures, when the angle of the fracture line is angled back (more posterior at the top of the jaw and more anterior at the bottom of the jaw) the muscles tend to bring the fracture segments together. This is called favorable. When the angle of the fractures is pointing to the front, it is unfavorable.
With age, the enlarging maxillary sinus may even begin to surround the roots of the maxillary posterior teeth and extend its margins into the body of the zygomatic bone. If the maxillary posterior teeth are lost, the maxillary sinus may expand even more, thinning the bony floor of the alveolar process so that only a thin shell of bone is present.
The air pressure is temporary as the posterior segment will soon re-fill with fluid. Air/gas exchange – In some cases, gas can be used to help hold the retina in place. Gas, or more typically mixed gas and air, is injected through the sclera and into the posterior segment of the globe. This procedure is often referred to as pneumatic retinopexy.
The splitting is not preceded by the development of the tissues to be lost. Prior to splitting, the animal may develop furrows at the zone of splitting. The headless fragment has to regenerate a complete head. In paratomy, the split occurs perpendicular to the antero-posterior axis and the split is preceded by the "pregeneration" of the anterior structures in the posterior portion.
The pleurocentra, which also comprise the centra, are slender and crescentic in both genera. Unlike Slaugenhopia, Kourerpeton lacks an incisure, or notch, on the pterygoid bone of the palate. In Slaugenhopia, this incisure appears as a deep notch in the posterior margin of the central palate. In Kourerpeton, the posterior edge of the skull table is strongly undulated, and has a medial concavity.

The temporal muscle is the most powerful muscle of the temporomandibular joint. The temporal muscle can be divided into two functional parts; anterior and posterior. The anterior portion runs vertically and its contraction results in elevation of the mandible (closing the mouth). The posterior portion has fibers which run horizontally and contraction of this portion results in retrusion of the mandible.
Arca imbricata grows to about 2 ins (5 cm) in length. The valves have a roughly rectangular shape with a rounded anterior end and a slightly pointed posterior end. They are usually purplish- white in colour, but live specimens are covered in a thin brown protective periostracum. There are some distinct ribs on the posterior end and the margin is smooth.

A large irregular leaden- grey circular spot is present on the upper angle of the cell. A whitish wedge- shaped patch can be found on the posterior corner of the forewing.
Sometimes, three deep temporal nerves are present branching from the anterior division of the mandibular nerve. In this case the extra nerve is situated between the anterior and posterior and called the middle deep temporal nerve. The anterior deep temporal nerve is sometimes a branch of the buccal nerve. The posterior deep temporal nerve is sometimes a branch of the masseteric nerve.

The angular prominence between the posterior margin of the vaginal process and the medial border of the scaphoid fossa is named the pterygoid tubercle, and immediately above this is the posterior opening of the pterygoid canal. On the under surface of the vaginal process is a furrow, which is converted into a canal by the sphenoidal process of the palatine bone, for the transmission of the pharyngeal branch of the internal maxillary artery and the pharyngeal nerve from the sphenopalatine ganglion. The pharyngeal aponeurosis is attached to the entire length of the posterior edge of the medial plate, and the constrictor pharyngis superior takes origin from its lower third. Projecting backward from near the middle of the posterior edge of this plate is an angular process, the processus tubarius, which supports the pharyngeal end of the Eustachian tube.

By contrast, velociraptorines often have larger serrations on the posterior side of the tooth, than the anterior, or no serrations on the anterior side at all. Genus List for Holtz 2012 Weight Information According to Turner et al.
There are also two buccal suckers at the anterior extremity. The digestive organs include an anterior mouth, a pharynx, an oesophagus and a posterior intestine that bifurcates at about the level of genital pore in two lateral branches. The intestinal branches terminate at posterior end of body proper, the left limb extends along the haptor and reaches the lappet. Each adult contains male and female reproductive organs.
They are posterior to the medial femoral condyle. The synovial sac of the knee joint can, under certain circumstances, produce a posterior bulge, into the popliteal space, the space behind the knee. When this bulge becomes large enough, it becomes palpable and cystic. Most Baker's cysts maintain this direct communication with the synovial cavity of the knee, but sometimes, the new cyst pinches off.
The posterior thoracic nucleus is a major relay center for unconscious proprioception. Sensory information from muscle spindles and tendon organs is carried by axons of larger neurons in dorsal root ganglia, which synapse onto neurons in the spinal cord including the posterior thoracic nucleus. From here information continues rostrally until it reaches the cerebellar cortex. This relay pathway is generally known as the dorsal spinocerebellar tract.
The anterior portion is sub-circular and is thought to be the true narial opening. The posterior portion likely held the salt gland. The expansion of the posterior portion may not be an accommodation for the salt gland, but rather a means of coping with cranial stresses during feeding. The postcranial skeleton is well known in Tambachia, given the completeness of the holotype specimen.
Group A11 is a small group of dopaminergic cells located in the posterior periventricular nucleus and the intermediate periventricular nucleus of the hypothalamus in the macaque. In the rat, small numbers of cells assigned to this group are also found in the posterior nucleus of hypothalamus, the supramammillary area and the reuniens nucleus. Dopaminergic cells in A11 may be important in the modulation of auditory processing.

These injuries are associated with diving injuries, falls and car accidents. Anterior compression vector results in mild height loss, whereas hyper-extension often occurs with the posterior displacement of the head in car crashes. Severe hyper-extension injury leads to pinching of the spinal cord along the posterior margin of the body. A common form of strain on ligaments and tendons in the arm.
Assume that q(\mu,\tau) = q(\mu)q(\tau), i.e. that the posterior distribution factorizes into independent factors for \mu and \tau. This type of assumption underlies the variational Bayesian method. The true posterior distribution does not in fact factor this way (in fact, in this simple case, it is known to be a Gaussian-gamma distribution), and hence the result we obtain will be an approximation.
GDF11 belongs to the transforming growth factor beta superfamily that controls anterior-posterior patterning by regulating the expression of Hox genes. It determines Hox gene expression domains and rostrocaudal identity in the caudal spinal cord. During mouse development, GDF11 expression begins in the tail bud and caudal neural plate region. GDF knock-out mice display skeletal defects as a result of patterning problems with anterior-posterior positioning.
The shell of Fabulina fabula is brittle and flattened and grows to a length of twenty millimeters. The outline is oval but the shell is asymmetric with the hinge slightly off centre and the beaks slightly behind the midline. The anterior dorsal margin curves gently and the anterior margin is rounded. The posterior dorsal margin is straighter and the posterior margin is somewhat pointed.
Axons from the rostral (gustatory) part of the solitary nucleus project to the ventral posterior complex of the thalamus, where they terminate in the medial half of the ventral posterior medial nucleus. This nucleus projects in turn to several regions of the neocortex which includes the gustatory cortex (the frontal operculum and the insula), which becomes activated when the subject is consuming and experiencing taste.
Posterior urethral valves (PUV) is an obstruction at the level of the urethra. It occurs in approximately 1 in every 5000 to 8000 live births and only occurs in males. Since PUV always affects both sides of the urinary tract, patients with posterior urethral valves are at the greatest risk for developing chronic kidney disease and end-stage renal disease due to obstructive uropathy.
Anterior sensillae and posterior sensillae are both nude. It presents a short line behind its sensillae's sockets, as well as two lines below and laterally to the posterior sensillae's sockets. Its idiosoma has eight setae between coxae I and II ventrally, 36 setae between coxae II and III and behind coxae III there are about 46 setulose setae. Its coxala Ib is its longest.
Four of those are arranged on the dorso- lateral part of the elytron. The two anterior spots form an roughly half-moon shaped oval with the convexity directed towards the suture of the elytron. The two posterior ones make a more irregular shape, formed by the intersection of two circular spots. Finally, the fifth spot covers the length of the elytron's suture, enlarging towards the posterior stretch.
The postorbitals are quite small, and there is weak sculpturing on the posterior processes. The squamosals, which form the posterior margins of the upper temporal fenestrae, are large and triradiate, with forked anterior processes. Their lateral processes just descend to meet the lower jaw. The quadratojugal is barely exposed at all, but the quadrate is just noticeable near the location of the occipital condyle.
The Notch of Rivinus is a small defect in the posterior edge of the bony annular tympanic ring. The defect is located just superior to the tympano- mastoid suture line in the posterior ear canal. Following identification of the spine of Henle it is possible to follow the tympano-mastoid suture line medially towards the annular ring. At this location the Chorda Tympani Nerve is often identified.
The inner end of the external acoustic meatus is closed, in the recent state, by the tympanic membrane; the upper limit of its outer orifice is formed by the posterior root of the zygomatic process, immediately below which there is sometimes seen a small spine, the suprameatal spine also called the spine of Henle, situated at the upper and posterior part of the orifice.
As many as 50% of people with radiographic instability are actually asymptomatic. Initial radiography should include flexion and extension lateral X-rays in addition to static anterior/posterior and lateral views. These views are often repeated every 2–3 years, especially in patients with new symptoms or possibly requiring future intubation. Progression of disease is measured via anterior atlantodental interval (AADI), and posterior atlantodental interval (PADI).
The digestive organs include an anterior, terminal mouth, a pharynx, an oesophagus and a posterior intestine with two lateral branches provided with numerous secondary branches. Each adult contains male and female reproductive organs. The reproductive organs include an anterior genital atrium, armed with numerous very spines, a medio-dorsal vagina , a single ovary and a number of testes which are posterior to the ovary.
There are no genal spines. Thorax of two segments; pleurae fulcrate with anterior pleural tips pointing backwards and those of the posterior segment directed forwards to enable enrolment. Pygidial axis is well defined, reaching or overhanging the posterior border, usually with five rings and commonly extending backwards into a prominent postaxial spine. The hypostome is a convex subquadrate plate, positioned directly under frontal part of the glabella.
The forewings are yellowish brown, with the basal and subbasal line black. The subbasal line has a purplish luster, and is triangularly broadened near to the posterior margin. The antemedian line in the costal half is slightly oblique and black, also with a purplish luster except at the margins. The hindwings are yellowish orange in the anterior half and dark brown in the posterior half.
It also shows a single band posterior to its last anal fin ray. Its head is not banded, the colour of which is dark brown dorsally, grading to a lighter brown ventrally, with no freckles. Its pectoral fin rays are brown, while its anal fin's membrane is divided into three parts: the anterior 40% is brown, the mid 40% is black, and the posterior 20% is translucent.
In the largest specimen (the paratype), the carapace was 18 mm (0.7 in) wide and 13 mm (0.5 in) long. Five parallel lines along the front margin that make up the ornamentation can be seen on the surface of the carapace. In the posterior portion, a series of small irregularly distributed tubercles (rounded protuberances) appear. In the posterior margin, there is a strip of fine triangular scales.
Capillary plexuses and lymphatic vessels spread from the retroperitoneal lymph sac to the abdominal viscera and diaphragm. The sac establishes connections with the cisterna chyli but loses its connections with neighbouring veins. The last of the lymph sacs, the paired posterior lymph sacs, develop from the iliac veins. The posterior lymph sacs produce capillary plexuses and lymphatic vessels of the abdominal wall, pelvic region, and lower limbs.
Banded archerfish have four dorsal spines, 11 to 13 dorsal soft rays, three anal spines (of which the third is longest) and 15 to 17 anal soft rays. The first spine is always the shortest; the rays become shorter toward the posterior end. There are about 23 scales between the first dorsal spine and the posterior nostrils. Certain areas of the body are tinged green.
