The catheter is now gently withdrawn until the beak is felt to catch against the posterior edge of the vomer.
The bones associated with the olfactory capsules are the nasals and vomer.
The true Dolphins also appear to show the same intervention of the vomer in a few cases.
Of these bones the vomer is never related to a cartilaginous tract below, while the palatines and pterygoids usually are so.
The V-shaped bone in front is called the vomer, while the hinder part is called pterygoid.
The oblique division into vomer in front and pterygoid bone behind is shown by Goldfuss in his original figure of Scaphognathus.
In the type-skull the form is the same as in the Atlantic City skull, but the vomer does not appear at all on the palate.
The premaxillaries, vomer, and nasals do not belong to the cranial scheme; they are covering bones connected with the ethmoid.
The vomer is approximately U-shaped, when viewed from below.
The vomer has a thin anterior ridge that gradually disappears before it reaches the border of the premaxillary.
vomer vo·mer (vō'mər)
A thin flat bone of trapezoidal shape that forms the inferior and posterior portion of the nasal septum and articulates with the sphenoid and ethmoid bones, the two maxillae, and the two palatine bones.
