Nose

Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration in conjunction with the mouth. Behind the nose are 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. In humans, the nose is located centrally on the face; on most other mammals, it is on the upper tip of the snout.

Famous quotes containing the word nose:

    The Aquarium is gone. Everywhere,
    giant finned cars nose forward like fish;
    a savage servility
    slides by on grease.
    Robert Lowell (1917–1977)

    If your nose is up in the air, you cannot see where you are going.
    Mason Cooley (b. 1927)

    I sometimes have the sense that I live my life as a writer with my nose pressed against the wide, shiny plate glass window of the “mainstream” culture. The world seems full of straight, large-circulation, slick periodicals which wouldn’t think of reviewing my book and bookstores which will never order it.
    Jan Clausen (b. 1943)
