The cartilage of the septum (or septal cartilage or quadrangular cartilage)is composed of hyaline cartilage. It 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.
