The roof of the nasal cavity is formed anteriorly by the nasal bones, the nasal spine of the frontal bone, and the floor of the frontal sinus. In its more horizontal midpart, the roof is formed by the cribriform plate of the ethmoid bone.part from the nasal vestibule which is lined by stratified squamous epithelium, nasal cavity is lined by pseudostratified columner ciliated epithelium i.e. respiratory epithelium. Each nasal fossa has four walls; roof, floor, septal wall, and lateral wall.
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.
