A nostril (or naris / ˈ n ɛər ɪ s /, pl.: nares / ˈ n ɛər iː z /) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture ...
Anterior nares are the external (or "proper") portion of the nose. The anterior nares open into the nasal cavity and allow the inhalation and exhalation of air. Each is an oval opening that measures about 1.5 cm anteroposteriorly and about 1 cm in diameter.
The ala of the nose (ala nasi, "wing of the nose"; plural alae) is the lower lateral surface of the external nose, shaped by the alar cartilage and covered in dense connective tissue. [1] The alae flare out to form a rounded eminence around the nostril. [17] Sexual dimorphism is evident in the larger nose of the male.
A nose is a sensory organ and respiratory structure in vertebrates. It consists of a nasal cavity inside the head, and an external nose on the face. The external nose houses the nostrils , or nares, a pair of tubes providing airflow through the nose for respiration .
A rhinolith (from rhino- 'nose' and -lith 'stone') is a stone present in the nasal cavity. It is an uncommon medical phenomenon, not to be confused with dried nasal mucus. A rhinolith usually forms around the nucleus of a small exogenous foreign body, blood clot or secretion by slow deposition of calcium and magnesium carbonate and phosphate ...
The external nasal nerve passes inferior-ward through the lateral nasal wall. It provides sensory innervation to the area of skin of the nose between the nasal bones superiorly and the tip of the nose inferiorly (excluding the alar portion surrounding the external nares).
Other ways to clear mucus from your nose. While blowing your nose is one of the easier ways to clear it out, there are other things you can do to reduce your congestion. Be sure to consult your ...
Frontonasal dysplasia (FND) is a congenital malformation of the midface. [1] For the diagnosis of FND, a patient should present at least two of the following characteristics: hypertelorism (an increased distance between the eyes), a wide nasal root, vertical midline cleft of the nose and/or upper lip, cleft of the wings of the nose, malformed nasal tip, encephalocele (an opening of the skull ...
