Septal nasal cartilage
The septal nasal cartilage (cartilage of the septum or quadrangular cartilage) is composed of hyaline cartilage.[1] It is somewhat quadrilateral in form, thicker at its margins than at its center, and completes the separation between the nasal cavities in front.

Anatomical terminology |
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 major 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.
