The
vomer () is one of the unpaired facial
bones of the
skull. It is located in the midsagittal line, and articulates with the
sphenoid, the
ethmoid, the left and right
palatine bones, and the left and right
maxillary bones. The vomer forms the inferior part of the nasal septum, with the superior part formed by the
perpendicular plate of the ethmoid bone. The name is derived from the Latin word for a ploughshare and the shape of the bone.
