The nasal septum, the division between the left and right airways of the nose, is made of three structures: the vomer bone, perpendicular plate of ethmoid bone, and its cartilage.
The medial wall of the nasal cavity is formed by both bony elements and cartilage. Posteriorly the perpendicular plate of the ethmoid bone forms the superior septum and the vomer forms the inferior part of the septum.Further posteriorly the crest of both the maxilla and palatine bone complete the posterior septum.he most medial end of the cartilage causes the elevation of the mucous membrane. The Hard Palate is a horizontal plate of bone formed by both the palatine process of the maxilla and the horizontal plate of the palatine bone.
