They meet one another in a long suture and form much of the posterior part of the palate, while the whole length of their dorsal surface contributes to the floor of the narial passage.
The internal or nasal surface, like that of the premaxillae, is excavated by a deep longitudinal groove, the =narial passage=.
They enclose the nasal organs, bound the inner side of the anterior narial opening, and are connected with one another posteriorly by a cartilaginous area.
In the natural condition it is divided into two by a vertical partition, formed by the =narial septum=, the anterior unossified part of the mesethmoid.
The =anterior narial opening= lies at the anterior end of the skull, and is bounded by the premaxillae and nasals.
Each also sends inwards a horizontal =palatine process=, which meets the palatine and vomer, and also forms much of the floor of the narial passage.
The narial passage is freely open, maxillo-turbinals not being developed.
On the orbital edge is a large hole leading into a cavity within the bone which lodges the naso-lachrymal sac, and communicates with the narialpassage by a wide second foramen near the anterior end of the bone.
The nasals are developed to a certain extent, and the nares, though placed very far back and near the top of the head, terminate forwardly-directed narial passages.
The narial aperture is thus pushed up, and is short, with an upward direction, as in the Cetacea and Sirenia, with whom the Proboscidea have certain affinities.
The anterior narial aperture in the skull opens upwards, but the orifices of the nostrils are placed at the end of the muzzle.
The asymmetry of the bones too is remarkable, although this is characteristic of all the catodon whales, especially as regards the bones of the anterior narial passages, the left of which is very much larger than the right.
Corresponding with the clumsy nose are very short nostrils, the commencement of the narial aperture being therefore very far back.
The maxilla encircles the posterior border of the naris and extends dorsally above the naris to an extent sufficient to indicate the probable exclusion of the lacrimal bone from the narial border.
The narial rim is wide, but wider ventrally than dorsally.
The naris in each is enlarged, and the lacrimal is excluded from the narial margin in each (by inference in Delorhynchus.
The plane of the narialrim is oblique to the lateral surface of the maxilla.
The free edge of each narial flap shows various degrees of fimbriation.
In ater at least, the anteriormost portions of the narial flaps seem wider than in the other forms and show a greater degree of fimbriation than the posteriormost parts.
As in the other anthropoids, the face is abbreviated, the narial region is narrow, i.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "narial" in a variety of sentences. We hope that you will now be able to make sentences using this word.
