38. The Vomer, Os vomeris. 



The v o m e r serves for the formation of the inferior part of the 

 bony Septum narium. The superior border is separated , forming 

 2 alae, the Alae vomens, between which the rostrum of the sphenoid is 

 received. The inferior border touches the Crista iiasalis, formed by 

 both superior maxillary and both palate bones. The anterior longest 

 border articulates at its upper portion with the perpendicular plate 

 of the ethmoid bone, at its lower with the quadrangular cartilage of the 

 septum, Septum cartilagineum. The posterior shortest border is free and 

 forms the septum of the posterior nares, which separates these from each 

 other, forming the two choanae. 



The vomer articulates with 6 bones: 2 of the cranium, the sphenoid 

 and ethmoid bones, and 4 of the face, the 2' superior maxillary and the 2 palate 

 bones ; finally with the quadrangular cartilage of the septum, Cartilago quadrangu- 

 laris s. Septum cartilagineum.
