The Vomer is a single relatively flat bone located in the mid-sagittal plane. It articulates with the perpendicular plate of the ethmoid superiorly and together aid in forming the nasal septum.
While it is frequently deflected slightly to the left or right, in general the septum is aligned perpendicularly and divides the the nasal aperture into the the left and right nasal passages. In addition to the Perpendicular Portion, superiorly the Vomer mushrooms out into a pair of Alae which terminate and articulate with the sphenoid in a heart shaped process. Inferiorly the Vomer rests on both the maxillae and the palatines.

The vomer touches, or articulates with, the following bones:

* Sphenoid
* Ethmoid
* Palatines
* Maxillae
