The length of the skeleton of an adult female, measured from the tip of the premaxillaries to the end of the sacral vertebrae, is 23.
Measure from the tip of the premaxillaries or outer insertion of the front teeth (incisors) along the palate to the nearest inner edge of the foramen magnum.
In infucata the premaxillarieslie in a transverse plane and have short, nearly vertical alary processes, whereas in pseudopuma the premaxillaries lie at a slight angle and have longer alary processes that are inclined posteriorly.
Contact of Maxillaries Above Premaxillaries The contact of the maxillaries above the premaxillaries is of diagnostic value in distinguishing skulls of ferox and spinifer from those of muticus.
The skull exhibits a partial attenuation anteriorly, thepremaxillaries are directed about equally downward and forward, and the nasal bones are measurably contracted in size.
Other differences might be added: thus the plane of the condyles is somewhat modified, and the terminal edge of the premaxillaries forms an arch.
In the Labrador duck the premaxillaries are rather broader than in the wild duck; and in two skulls of this breed the vertical ridges on each side of the supra-occipital bone are very prominent.
In the Penguin the premaxillaries are relatively shorter than in the wild duck; and the inferior points of the paramastoids more prominent.
The premaxillaries appear simultaneously with the maxillaries.
The maxillaries bear well-developed dorsal flanges, curve gently, join the moderately convex premaxillaries anteriorly and form a slightly truncate snout.
After the maxillaries and premaxillaries develop, the vomers appear as small horizontal ossifications anterior to the parasphenoid.
The vomers are moderately large and are in contact anteriorly with the premaxillaries and posteriorly with the ethmoid.
The septomaxillaries are closely associated dorsally with the premaxillaries immediately lateral to the prenasal processes.
The premaxillaries are separated medially, and laterally from the maxillaries by sutures.
The premaxillariesare small, but are larger in Dasypus than in Tatusia.
Thus the premaxillaries take their fair share in the outline of the upper jaw; and, furthermore, bear the incisor teeth.
The premaxillaries are very small, and are usually lost in dried skulls.
The skull is on the whole Rorqual-like; but its fore-part is narrow as in the Greenland Whale, and the premaxillaries are pinched up in the middle line so as to be visible from the side; this again is a Balaenid character.
The alary processes of the premaxillaries are vertically oriented in leprieurii, pearsoni, and taurinus and very slightly inclined posteriorly in buckleyi and verrucigerus.
This subtle difference relates to the relative narrowness of the premaxillaries in buckleyi.
The shape of the posterior edge of the bony palate is also variable, being convex, square, or concave; and the dorsal branches of the premaxillaries may terminate slightly anterior or slightly posterior to the posterior ends of the nasals.
In the type the posterior palatal margin is concave and the dorsal branches of the premaxillaries almost reach the ends of the nasals.
The border of the mouth above is formed mesially by the small premaxillaries and laterally by the maxillaries.
In this group thepremaxillaries and maxillaries are present as in ordinary fishes, but united by suture and soldered to the cranium.
In this group the small mouth is extremely protractile, its margin formed by the premaxillaries alone much as in the spiny-rayed fishes.
The vomers, separated by a longitudinal suture, appear in the palate between the premaxillaries and the palatine plates of the maxillaries.
The nasals join the premaxillaries opposite the ninth tooth, and the splenial bones, in the lower jaw, end opposite the tenth mandibular tooth, as the figures of Mueller and Schlegel show.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "premaxillaries" in a variety of sentences. We hope that you will now be able to make sentences using this word.
