The vomer has 4 borders:
- superior: thickest border with laterally projecting alae which articulate with the rostrum of the sphenoid bone body. The alae also articulate with the:
- inferior: articulates with the median nasal crest of the maxilla and palatine bones, between the incisive canals
- anterior: longest border which articulates with:
- the perpendicular plate of the ethmoid bone along its upper half
- the nasal septal cartilage along its lower half
- posterior: short concave border which is thicker (and bifid) superiorly and which does not articulate with any bone, but rather separates the posterior choanae
The vomerovaginal canal is formed between the ala, body of the sphenoid and the small medially directed vaginal process arising from the sphenoid bone.
Occasionally the sphenoid sinus may pneumatize the vomer .
