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 lower part of the nose is made up of cartilages which are responsible for the shape of external features of the nose. The nose bridge and the septal cartilage form the nasal septum. This nasal septum separates the nostrils. The nostrils continue with nasal cavity. The turbinate or conchae are the bones that divide nasal cavity into air passages. The diagram below explains the anatomy of the nose:
