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.
General structure. The right and left nasal cavities are separated by the vertical nasal septum. Each nasal cavity is tall, narrow, and elongated, resembling the nave of a gothic cathedral. Its roof is the floor of the anterior cranial fossa, its floor is the roof of the oral cavity.Laterally, it is flanked by the orbit (above) and the maxillary sinus (below). The nasal vestibule, just inside the nostrils, is lined with stratified squamous epithelium, bearing coarse hairs.ach nasal cavity is tall, narrow, and elongated, resembling the nave of a gothic cathedral. Its roof is the floor of the anterior cranial fossa, its floor is the roof of the oral cavity. Laterally, it is flanked by the orbit (above) and the maxillary sinus (below).
