Cartilage of the septum
Bones and cartilages of septum of nose. Right side. (Cartilage of the septum visible as blue structure atright.)
Cartilages of the nose, seen from below. (C. of septum visible in blue at bottom center.)
Latin	cartilago septi nasi
Gray's	subject #223 992

The cartilage of the septum (or septal cartilage, or quadrangular cartilage) is somewhat quadrilateral in form, thicker at its margins than at its center, and completes the separation between the nasal cavities in front.

Its anterior margin, thickest above, is connected with the nasal bones, and is continuous with the anterior margins of the lateral cartilages; below, it is connected to the medial crura of the greater alar cartilages by fibrous tissue.

Its posterior margin is connected with the perpendicular plate of the ethmoid; its inferior margin with the vomer and the palatine processes of the maxillae.
