Rostral nasal concha presents stratified squamous cornified epithelium. It consists of a basal cell layer cube, slightly irregular. It goes to the surface of cell columns perpendicular to the basal layer. The skeleton is composed of hyaline cartilage cones and lamina propria contains numerous blood vessels. Middle nasal concha is located in the respiratory region of the nasal cavity. Presents a hyaline cartilaginous skeleton, bounded by a thickened pericondru. It is covered with a respiratory type mucosa and with ciliated columnar pseudostratified epithelium with goblet cells. In the structure of the alveolar mucosa lists numerous large aspect mucous glands that open directly to the surface epithelium. Goblet cells are rare and their function is taken over by alveolar glands. In the conjunctive space between glands and basement membranes we find limphoid cells nucleis represented by: lymphocytes, plasma cells and macrophages.
