The roof of each nasal cavity is formed in its upper third to one half by the nasal bone and more inferiorly by the junctions of the upper lateral cartilage and nasal septum.Connective tissue and skin cover the bony and cartilaginous components of the dorsum of the nose.he nasal cavity (or nasal fossa) is a large air filled space above and behind the nose in the middle of the face. Each cavity is the continuation of one of the two nostrils.
It contains the sockets where the incisor teeth are held. It also contains the anterior nasal spine, the whole thickness of the alveolus and the corresponding part of the floor of the nose. The hard palate creates part of the roof of the mouth. It is concave and covered with holes called foramina. These holes allow the passageway of nutrient vessels, palatine vessels and nerves. The surface is uneven and rough to the touch.
