It has two surfaces and four borders.

Vomer anatomy. The vertical plate of the vomer bone articulates with the perpendicular plate of the ethmoid bone to form the bony nasal septum. The vomer is situated in the median plane but its anterior portion is frequently bent to one or other side. The anterior border is the longest and slopes downward and forward.

Short concave border the. It is unpaired and lies in the midline between the two nasal cavities. In skull cavity is formed by the vomer and the nasal lachrymal and turbinate bones.

Thickest border with laterally projecting alae which articulate with the rostrum. Its upper half is fused with the perpendicular plate of the ethmoid. It is thin somewhat quadrilateral in shape and forms the hinder and lower part of the nasal septum fig.

The septum separates the nasal cavity into two halves called nasal fossae. The posterior border is free concave and separates the choanæ. 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.

Vomer bone l plowshare a thin plow shaped bone. Articulates with the median nasal crests of the maxilla and palatine bones. With the help of these wings the vomer attaches to the inferior surface of the body of the sphenoid bone.

The vomer is a single facial bone that takes a form of a plate and its superior border gives two extensions called wings. The vomer ˈ v oʊ m ər is one of the unpaired facial bones of the skull. The vomer is one of the facial bones and forms the postero inferior part of the bony nasal septum.

174 are marked by small furrows for blood vessels. It is thick and bifid above thin below. It is a thin flat bone that is trapezoidal in shape with two surfaces that are obliquely grooved by the sphenopalatine nasopalatine vessels and nerves.

Its lower half is grooved for the inferior margin of the septal cartilage of the nose. Longest border which articulates with. The vomer articulates with the following bones.

The vomer has 4 borders.
