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:

    Better a snotty child than his nose wiped off.
    English proverb, collected in George Herbert’s Outlandish Proverbs (1640)

    My uncle Toby had scarce a heart to retalliate upon a fly.
    Go,—says he, one day at dinner, to an over-grown one which had buzz’d about his nose ... go poor Devil, get thee gone, why should I hurt thee?—This world surely is wide enough to hold both thee and me.
    Laurence Sterne (1713–1768)

    your antlers like seaweed,
    your face like a wolf’s death mask,
    your mouth a virgin, your nose a nipple,
    your legs muscled up like knitting balls,
    your neck mournful as an axe....
    Anne Sexton (1928–1974)
