55 Sentences With "more posterior" | Random Sentence Generator

It is visually distinguished from other species of the E. percnurum complex by a more posterior anal fin.

In comparison, the southern sleeper shark differs from S. microcephalushas in having more tooth rows in the lower jaw, a shorter interdorsal region, a more posterior first dorsal fin, and fewer precaudal vertebrae, and from both species in having lower dorsal fins.

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.

In anatomy, the urogenital hiatus is the structure through which the urethra and the vagina pass. It is located in the anterior (front) of the pelvic floor. The pelvic floor has two hiatuses (gaps). The other is the more posterior 'rectal hiatus', through which the anal canal pass.

The abdomen is also known as the opisthosoma. On the ventral side of the abdomen are two hardened plates covering the book lungs. These are called the epigastric plates. A fold, known as the epigastric furrow, separates the region of the book lungs and epigyne from the more posterior part of the abdomen.

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.

The neck of Leonorasaurus is known almost completely, only the atlas is lost. The nine remaining cervicals were found articulated with the first five complete dorsal (trunk) vertebrae. Additionally, a probable sixth dorsal and an articulated group of three mid-dorsals were found. Fragments of more posterior dorsals and of ribs were also recovered.

The events of reproduction are: #The basal body duplicates and both remain associated with the kinetoplast. Each basal body forms a separate flagellum. #Kinetoplast DNA undergoes synthesis then the kinetoplast divides coupled with separation of the two basal bodies. #Nuclear DNA undergoes synthesis while a new flagellum extends from the younger, more posterior, basal body.

Five teeth are present in Euprenolepis queens and five or fewer in Pseudolasius, while Nylanderia possesses six (or rarely seven) teeth. In other genera such as Paratrechina and Paraparatrechina, the queens have no erect macrosetae on their scapes. For Prenolepis, if erect macrosetae are present on the scapes, the more posterior placement of the eyes distinguishes them from Nylanderia.

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.

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.

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.

The median palatal cyst is a rare cyst that may occur anywhere along the median palatal raphe. It may produce swelling because of infection and is treated by excision or surgical removal. Some investigators now believe that this cyst represents a more posterior presentation of a nasopalatine duct cyst, rather than a separate cystic degeneration of epithelial rests at the line of fusion of the palatine shelves.

Each parasegment includes the posterior part of one (future) segment, and an anterior part of the next (more posterior) segment. The bands of expression of the pair-rule genes correspond to the regions missing in the mutant. The expression of the pair-rule genes in bands is dependent both upon direct regulation by the gap genes and on regulatory interactions between the pair-rule genes themselves.

Xiphinema diversicaudatum are large nematodes, 4.0mm-5.5mm in length. They have a long protrusible odontostyle, which is around 0.1 mm long and capable of penetrating into a host’s vascular tissue. The long stylet is similar to Longidorus but is distinguishable by 3 posterior basal flanges and a more posterior guiding ring than is observed in Longidorus. Xiphinema have a two-part esophagus, which does not contain a metacorpus.

The term "M1" and the term "primary motor cortex" are often used interchangeably. However, they come from different historical traditions and refer to different divisions of cortex. Some scientists suggested that the motor cortex could be divided into a primary motor strip that was more posterior and a lateral premotor strip that was more anterior. Early researchers who originally proposed this view included Campbell, Vogt and Vogt, Foerster, and Fulton.

Certain language functions such as word retrieval and production were found to be located to more anterior language cortices, and deteriorate as a function of age. Sowell et al., also reported that these anterior language cortices were found to mature and decline earlier than the more posterior language cortices. It has also been found that the width of sulcus not only increases with age, but also with cognitive decline in the elderly.

The pectoral fins of Stethacanthus were composed of the triangular-shaped metapterygium observed in modern-day sharks, but had an additional long, metapterygial structure called a fin whip. These fin whips contain at least 22 axial cartilages and extended past the pelvic fins. The three most anterior axials are shorter than the more posterior axials. The purpose of the fin whips is unknown but it has been suggested that they were used during mating.

Homonymous hemianopsia can be congenital, but is usually caused by brain injury such as from stroke, trauma, tumors, infection, or following surgery. Vascular and neoplastic (malignant or benign tumours) lesions from the optic tract, to visual cortex can cause a contralateral homonymous hemianopsia. Injury to the right side of the brain will affect the left visual fields of each eye. The more posterior the cerebral lesion, the more symmetric (congruous) the homonymous hemianopsia will be.

One interesting feature of the occlusal pattern in Suminia dentition is the angle of the occluding surfaces. With an angle of 75 degrees from jaw plane, it is suggested that Suminia’s more posterior shreds food material rather than crush it. The anterior teeth are observed to be significantly larger and devoid of this occlusial pattern. Therefore, the more anterior teeth are suggested to be responsible for cutting off pieces of plant for the posterior teeth to shred.

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.

The heart is a biological pump designed to move blood through the brain and body. It has four chambers: two "upper" chambers called the atria, and two "lower" chambers called the ventricles. Anatomically, the atria are more posterior to the ventricles, but for ease of understanding, are often drawn "above" them. The atria are separated from the ventricles beneath by the atrioventricular valves, which open to allow blood into the ventricles and close when ventricular pressure exceeds atrial pressure.

Since the dorsal, anal and caudal fins are fused there is no need for pelvic fins. Dorsal fin begins mid body creating a long continuous fin where in other species it begins more posterior and is not as prominent in length. Their body movement depends highly on undulation originating near the anterior axial end. Due to the fins being fused we see a highly skilled swimmer amongst the Anguillidae which aids in migration and hunting/predation.

There is a single ovary, located at mid-length of the body, and numerous testes, more posterior. The oötype wall has longitudinal rows of large cells (a structure called "ootype côtelé" by Euzet & Maillard, 1974). The eggs are elongate, fusiform, with a single terminal filament. The species is distinguished from other species of the genus Protocotyle by the following combination of characters: posterior lobe of seminal vesicle absent, diverticulum of oviduct present, and small body size.

This is called ectopia. For example, when one gene is lost the segment develops into a more anterior one, while a mutation that leads to a gain of function causes a segment to develop into a more posterior one. Famous examples are Antennapedia and bithorax in Drosophila, which can cause the development of legs instead of antennae and the development of a duplicated thorax, respectively. In vertebrates, the four paralog clusters are partially redundant in function, but have also acquired several derived functions.

Their mouth and gill openings are situated on the ventral surface of the head (top right). In the most primitive forms, such as the Silurian genus Hanyangaspis (top), the median dorsal inhalent opening is broad and situated anteriorly. In other galeaspids, it is more posterior in position and can be oval, rounded, heart-shaped or slit-shaped. In some Devonian galeaspids, such as the hunanaspidiforms Lungmenshanaspis (middle) and Sanchaspis (bottom right), the headshield is produced laterally and anteriorly into slender processes.

Like the more posterior premolars, it is buccolingually compressed and double-rooted. It has a dominant central protocone flanked by denticles that decrease in size mesially and distally, resulting in a tooth with a triangular profile. P3 is similar to but slightly smaller than P2, except that it has a projection on the lingual side which is the remnant of a third root. In P4, smaller than P2–3, the larger distal root is formed by the fusion of two roots.

The skull of Anaschisma is also covered in this reticulate ornamentation. Some researchers believe that Anaschisma has a shorter posterior process of the interclavicle, which may discriminate it from other closely related species, while others believe that there is not enough information to make that distinction. Anaschisma also has ossified opisthotics, the more posterior of the bones surrounding the inner ear. Size of Anaschisma (large) and Apachesaurus (small) compared to a human Anaschisma had sharp, pointy teeth for catching and killing prey.

Many isolated teeth found throughout Cretaceous Nigeria can be assigned to Goronyosaurus, because of its unique tooth anatomy. Such isolated teeth display a similar polymorphic tapering, with crowns that become blunter towards the back of the tooth row. These fit the morphology of Goronyosaurus to the exclusion of all other mosasaurs, except in the fact that such isolated teeth lack the fluted grooves of Goronyosaurus. Teeth from the front of the dentary are slightly more robust than those more posterior, but still curve gently back.

The two drugs that have been well-described for the treatment of hymenolepiasis are praziquantel and niclosamide. Praziquantel, which is parasiticidal in a single dose for all the stages of the parasite, is the drug of choice because it acts very rapidly against H. nana. Although structurally unrelated to other anthelminthics, it kills both adult worms and larvae. In vitro, the drug produces vacuolization and disruption of the tegument in the neck of the worms, but not in more posterior portions of the strobila.

Premolar 3 and molars one and two are missing with the alveolus intact, mo material remains after molar three. Muirhead (1997 p. 372) describes W. ridei as having the following features that are unique: parametacrista on the first molar is straight, entoconid either missing of combined with the hypoconid in a more posterior position, the loss or reduction of styler crests, small metaconid, talonid basin reduced by the lingual (toward the tongue) placement of the hypoconid. Dasyurid type features include the infraorbital foramen away from the jugal and a large hypoconid.

This is a large but morphologically uniform genus of rather delicate erebid moths with distinctively patterned wings, the hindwings usually having most elements of the forewing pattern. The ground color of the wings is usually pale fawn or grayish, and the forewing postmedial line is usually angled or curved round the discal area, though its more posterior oblique section may be continued by one of its components towards the apex. The male antennae are ciliate, and the legs are often tufted with scale crests and hair pencils. The labial palps are typical for catocalines.

However, the short mouth, blunted edges of the lower jaw, and the lack of a tough palatal surface against which the jaw could grind downplay the significance of this apparent shearing component. The morphology of the jaw hinge prevents the anterior end of the lower jaw from meeting the palate, only allowing palatal contact with the more posterior portion of the dentary. While there is little possibility of any transverse movement in the lower jaw, a crushing function is possible, and consistent with the feeding mechanism observed in other Emydopoids.Cox, C. B. 1998.

It had three bony crests: a low crest on the snout, a short low parietal crest on top of the skull and a short traverse crest connected to the front edge of the latter. The parietal crest is the first reported for a non-pterodactyloid pterosaur. The same is true for the rosette, bearing two pairs of forward pointing laniaries, formed by a narrowing of the snout behind these long fangs. Another probably five pairs of teeth were present in a more posterior position in the upper jaws.

Unlike mouse lemurs and more like dwarf lemurs, giant mouse lemurs have a prominent anterior lower premolar (P2). Also more aligned with dwarf lemurs, the first two upper molars (M1–2) have a more anterior hypocone that sits opposite the metacone, compared to the mouse lemurs' more posterior hypocone, which is presumably a symplesiomorphic (ancestral) trait. Also on M1 and M2, the cingulum (a crest or ridge on the tongue side) comprises two small cuspules. In all other dental characteristics, giant mouse lemurs are noticeably similar to both dwarf and mouse lemurs.

Participants with clinically diagnosed Obsessive Compulsive Disorder have exhibited ERN deflections with increased amplitude, prolonged latency, and a more posterior topography compared to clinically normal participants. ERN latency has been manipulated through rapid feedback, wherein participants who received rapid feedback regarding the incorrect response subsequently showed shorter ERN peak latencies. Additionally, a heightened ERN amplitude during social situations has been linked to anxiety symptoms in both childhood and adulthood. Developmental studies have shown that the ERN emerges throughout childhood and adolescence becoming more negative in amplitude and with a more defined peak.

The PFC has been found to be active in a variety of tasks that require executive functions. This has led some researchers to argue that the role of PFC in working memory is in controlling attention, selecting strategies, and manipulating information in working memory, but not in maintenance of information. The maintenance function is attributed to more posterior areas of the brain, including the parietal cortex. Other authors interpret the activity in parietal cortex as reflecting executive functions, because the same area is also activated in other tasks requiring attention but not memory.

In higher animals including humans, retinoic acid regulates differential expression of Hox genes along the anteroposterior axis. Genes in the 3' ends of Hox clusters are induced by retinoic acid resulting in expression domains that extend more anteriorly in the body compared to 5' Hox genes that are not induced by retinoic acid resulting in expression domains that remain more posterior. Quantitative PCR has shown several trends regarding colinearity: the system is in equilibrium and the total number of transcripts depends on the number of genes present according to a linear relationship.

The longest is metatarsal III with a length of ; it is placed more anteriorly than the other metatarsals. Metatarsal I is more posterior and its upper part is transversely reduced to a splint. Some distinguishing traits of Jeholosaurus include: enlarged laterodorsal nasal foramina; a quadratojugal fenestra more than 25% maximum quadratojugal length; a quadratojugal less than 30% of skull height; a predentary with almost 150% of premaxillary body length; a dentary extending posteriorly almost to the posterior border of the angular; and the claw of the third toe being longer than the other third toe phalanges.

Bicoid and Hunchback are the maternal effect genes that are most important for patterning of anterior parts (head and thorax) of the Drosophila embryo. Nanos and Caudal are maternal effect genes that are important in the formation of more posterior abdominal segments of the Drosophila embryo. In embryos from bicoid mutant mothers, the head and thoracic structures are converted to the abdomen making the embryo with posterior structures on both ends, a lethal phenotype. Cytoskeletal elements such as microtubules are polarized within the oocyte and can be used to allow the localization of mRNA molecules to specific parts of the cell.

The wavefront progress slowly in an posterior-to-anterior direction. As the wavefront of signaling comes in contact with cells in the permissive state, they undergo an epithelial-mesenchymal transition and pinch off from the more posterior pre-somitic mesoderm, forming a somite boundary and resetting the process for the next somite. In particular, the cyclic activation of the Notch pathway appears to be of great importance in the wavefront-clock model. It has been suggested that the activation of Notch cyclically activates a cascade of genes necessary for the somites to separate from the main paraxial body.

In contrast, pincer impingement is a result of an abnormality on the acetabular side of the hip joint. The acetabulum may either have a more posterior orientation than normal, otherwise known as acetabular retroversion (seen as the crossover sign on AP radiographs), or there may be extra bone around the rim. This results in contact of the femoral neck against the labrum and rim of the acetabulum during hip movement earlier than might otherwise be the case. Repeated contact between the femoral neck and the edge of the acetabulum may lead to damage to the labrum and adjacent articular cartilage.

Whether Dickkopf-1 and Nodal act directly on the cardiac mesoderm is the subject of research, but it seems that at least they act indirectly by stimulating the production of additional factors from the anterior endoderm. These early signals are essential for heart formation such that removal of the anterior endoderm blocks heart formation. Anterior endoderm is also sufficient to stimulate heart differientation since it can induce non-cardiogenic mesoderm from more posterior positions in the embryo to form heart. The secretion of Wnt inhibitors (such as Cerberus, Dickkopf and Crescent) by the anterior endoderm also prevents Wnt3a and Wnt8 secreted by the neural tube from inhibiting heart formation.

The dorsal vertebrae are more rounded with flat spines; the first three or four carry ribs that contact the sternal ribs; the more posterior ribs contact the gastralia. The first five or six, rather short, caudal vertebrae form a flexible tail base. To the back the caudals grow longer and are immobilised by their intertwining extensions with a length of up to five vertebrae which together surround the caudals with a bony network, allowing the tail to function as a rudder. D. banthensis restoration; the tail form is hypothetical The breastbone is triangular and relatively small; Padian has suggested it may have been extended at its back with a cartilaginous tissue.

As the primary hypoblast cells move away from the PMZ, Cerberus protein is no longer present, allowing Nodal activity (and, therefore, forming the primitive streak) in the posterior epiblast. Once formed, however, the streak secretes its Nodal antagonist—the Lefty protein—which prevents further primitive streaks from forming. Eventually, the Cerberus-secreting hypoblast cells are pushed to the future anterior of the embryo, where they contribute to ensuring that neural cells in this region become forebrain rather than more posterior structures the nervous system. As the primitive streak reaches its maximum length, transcription of the Sonic hedgehog gene (Shh) becomes restricted to the embryo's left side, controlled by activin and its receptor.

The anterior end of the Mexican hat forms a cellulose tube, which allows the more posterior cells to move up the outside of the tube to the top, and the prestalk cells move down. This rearrangement forms the stalk of the fruiting body made up of the cells from the anterior end of the slug, and the cells from the posterior end of the slug are on the top and now form the spores of the fruiting body. At the end of this 8– to 10-hour process, the mature fruiting body is fully formed. This fruiting body is 1–2 mm tall and is now able to start the entire cycle over again by releasing the mature spores that become myxamoebae.

The more posterior P2 has been studied in relation to visual complexity in language processing, visual search tasks and memory and repetitions paradigms. The component is evoked as part of the normal response to visual stimuli, but the amplitude and latency (delay between stimulus and response) may be affected by exogenous factors, such as repeated visual stimuli. This component has been linked with higher-order perceptual and attentional processes, including feature analysis of geometric figures and visually presented words. The exact function and neural source of the P2 is not yet known, but some evidence indicates that the P2 may reflect general neural processes that occur when a visual (or other sensory) input is compared with an internal representation or expectation in memory or language context.

Regeneration in L. variegatus follows a set pattern. If the regenerating segment originated less than eight segments from the anterior tip, this number of segments are regenerated; if, however, the segment was originally from a more posterior position, only eight segments are regenerated. Posterior to the segment, a variable number of segments are regenerated, and the original segment undergoes transformation to become suited to the new, often more anterior position. L. variegatus is presumed to be holarctic in distribution, although in East Asia and North America (and perhaps other places as well), it is probably replaced by the other species of the genus (many of which are known from very small areas; L. illex, for instance, is known only from three individuals found in a stream north of Vladivostok).

Size of Anomalocaris compared to an average-sized human hand For the time in which it lived, Anomalocaris was gigantic, up to long. It propelled itself through the water by undulating the flexible flaps on the sides of its body. Each flap sloped below the one more posterior to it, and this overlapping allowed the lobes on each side of the body to act as a single "fin", maximizing the swimming efficiency. The construction of a remote-controlled model showed this mode of swimming to be intrinsically stable, implying that Anomalocaris would not have needed a complex brain to manage balance while swimming. The body was widest between the third and fifth lobe and narrowed towards the tail; it was thought to have at least 11 pairs of flaps in total.

The number and nature of the post-oral segments in the insect head have rarely been questioned. A much more difficult area, however, has been the nature of the preoral region. The obvious contradiction between a theory that no-preoral structures are segmental, and evidence, such as for the first antennae of crustaceans, that some such structures clearly are, led workers as long ago as Lankester to posit that there has been forward migration of segments in front of the mouth. Indeed, such a process can be seen in ontogeny of the tritocerebrum, which can be seen to migrate forward as the brain develops; furthermore, although in most insects and crustaceans its ganglia are part of the brain, its commissures still loop behind it, suggesting derivation from a more posterior position.

Notably, Smith noticed that the position of the lunate sulcus was more posterior in human, especially those of European descent, as compared to monkey brains. Based on this observation, he was the first to hypothesize that the caudal shift of the lunate sulcus in Homo sapiens was due to the evolutionary rapid overgrowth of the cerebral cortex that is unique to human neurodevelopment. Smith’s observation that the caudal shift of the lunate sulcus could also be used as a predictor for determining both the evolutionary posterolateral shift of the occipital lobes/V1 and the corresponding expansion of the neighboring parietotemporo- occipital visual association cortices was supported by recent research. However, some scientists today disagree with Smith’s assertion that a lunate sulcus exists in humans, arguing that there is only an Affenspalte which is solely unique to apes.

Other parts of the movement repertoire, such as manipulating an object with the fingers once the object has been acquired, or manipulating an object in the mouth, involve less planning, less computation of spatial trajectory, and more control of individual joint rotations and muscle forces. In this view the more complex movements, especially multi-segmental movements, come to be emphasized in the more anterior part of the motor map because that cortex emphasizes the musculature of the back and neck which serves as the coordinating link between body parts. In contrast the simpler parts of the movement repertoire that tend to focus more on the distal musculature are emphasized in the more posterior cortex. In this alternative view, though movements of lesser complexity are emphasized in the primary motor cortex and movements of greater complexity are emphasized in the caudal premotor cortex, this difference does not necessarily imply a control hierarchy.

When viewing the Eusthenodon skull in dorsal view, the fenestra exonarina can be seen positioned high and laterally in the snout. Of the three temporal bones that make up the parietal shield present in osteolepiformes (intertemporal, supratemporal, and extratemporal), the presence of the extratemporal bone in a ‘postspiracular’ position, defined as the shift of the bone from a position lateral to the supratemporal to a more posterior-lateral position, is a significant and diagnostic character of the Tristichopteridae clade. The extratemporal bone present in Eusthenodon is notable for its complete postspiracular position resulting in no contact between the supratemporal and extratemporal bones, a condition known only to exist in Eusthenodon. One theory to explain the trend observed in the posterior shift of the extratemporal bone in more derived fishes suggests that the change in head proportions contributed to a more streamlined body shape and enhanced its maneuverability and speed in its aquatic environment.

Siamodon shows a combination of plesiomorphic and apomorphic features, including a maxilla shaped like an isosceles triangle, with the dorsal process located at about mid-length of the bone; a strong longitudinal bulge on the medial surface of the maxilla; at least 25 maxillary teeth, which bear a prominent median primary ridge, and one short weak subsidiary ridge or no subsidiary ridge at all, and mamillated denticles on the crown margins. The maxilla is 230 millimeters long, and has a height of 100 millimeters. The height of the isolated tooth is about 25-28 millimeters, and the width is about 14-17 millimeters. Siamodon differs from more basal iguanodontians, such as Iguanodon and closely related forms, in the morphology of its maxillary teeth, which are narrower and bear a strong median primary ridge, sometimes accompanied by a weak subsidiary ridge, instead of a distally displaced primary ridge and several subsidiary ridges, and the apex of the maxilla is in a more posterior position.

Holotype skull The holotype, AR-1/10, represents a disarticulated partial skeleton spread over an area of seven by three meters. It consists of a nearly complete skull, isolated left and right nasals, a dentary fragment, 15 isolated teeth, an atlas, five cervical vertebrae, two cervical ribs, possibly the first and seven more posterior dorsal vertebrae, a section of synsacrum, three isolated dorsal ribs, seven dorsal rib fragments, three caudal vertebrae, four chevrons, a coracoid with a small portion of the scapula, a scapular blade fragment, two xiphosternal plates, both partial humeri, right articulated ilium, ischium and pubis, left articulated ischium and pubis, and 70 osteoderms. The second partial skeleton AR-1/31, designed as the paratype, consists of a partial left jaw with dentary and surangular and isolated angular, ten teeth, five cervical, nine dorsal, three or four dorsosacral, one caudosacral and 14 caudal vertebrae, a sacrum, two sacral rib fragments, both ischia with fused pubes, two left ilium fragments, complete right ilium, femur, tibia and fibula, a calcaneum, four metatarsals, eight phalanges, nine unguals, and 90 osteoderms.
