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.
Describe the bony features of the nasal cavity. The nasal cavity is mostly formed by the union of the maxillae. The ethmoid bone is at the rood of the nasal cavity. The perpendicular plate of the ethmoid and the vomer make the bony septum dividing the nasal activity into right and left sides. On the lateral walls of the maxillae are the inferior nasal conchae.
