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.
Smell and the Structure of the Nasal Cavity. Inside your nose is an open area called the nasal cavity. On the. roof of the nasal cavity are special sensory cells called olfactory. receptor cells. They extend through small holes in the bony roof. of the nasal cavity (the ethmoid bone of the skull). This sieve-like. structure is called the cribriform plate.
