| nasal pits | The paired depressions formed when the nasal placodes come to lie below the general external contour of the developing face as a result of the rapid growth of the adjacent nasal elevations; the pit's are the primordia of the rostral portions of the nasal chambers. Synonym: olfactory pits. (05 Mar 2000) |
| nasal placodes | Paired ectodermal placode's which come to lie in the bottom of the olfactory pits as the pits are deepened by the growth of the surrounding medial and lateral nasal processes. Synonym: nasal placodes. (05 Mar 2000) |

| nasal polyp | <otolaryngology> A projection of the mucosa lining the nasal and paranasal sinuses that is rounded and elongated within the nasal cavity. A common cause for nasal airway obstruction in patients who suffer from allergic sinusitis. They are found more commonly in those with chronic allergic rhinitis or sinusitis. Large nasal polyps can interfere with nasal breathing and are often removed surgically to improve breathing and decrease chronic allergic symptoms. (27 Sep 1997) |

| nasal ridge | An elevation on the lateral wall of the nasal cavity lying between the atrium of the middle meatus and the olfactory sulcus; it is formed by the mucous membrane covering the base of the ethmoidal crest of the maxilla. Synonym: nasal ridge. (05 Mar 2000) |
| nasal sacs | The deepened nasal pits that develop into the definitive nasal cavities. (05 Mar 2000) |

| nasal cavity |
Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration. In most mammals, it also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose is the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. ...

| nasal polyp |
Nasal polyps are polypoidal masses arising mainly from the mucous membranes of the nose and paranasal sinuses. Nasal polyps are usually classified into antrochaonal polyps and ethmoidal polyps. Antrochaonal polyps arise from the maxillary sinuses and the ethmoidal polyps arise from the ethmoidal sinuses. Antrochoanal polyps are usually single and unilateral whereas ethmoidal polyps are multiple and bilateral. ...
