Tongue
The tongue is a muscular hydrostat on the floors of the mouths of most vertebrates which manipulates food for mastication. It is the primary organ of taste (gustation), as much of the upper surface of the tongue is covered in papillae and taste buds. It is sensitive and kept moist by saliva, and is richly supplied with nerves and blood vessels. In humans a secondary function of the tongue is phonetic articulation. The tongue also serves as a natural means of cleaning one's teeth. The ability to perceive different tastes is not localised in different parts of the tongue, as is widely believed. This error arose because of misinterpretation of some 19th-century research (see tongue map).

Famous quotes containing the word tongue:
“I who have cursed
The drunken officer of British rule, how choose
Between this Africa and the English tongue I love?
Betray them both, or give back what they give?
How can I face such slaughter and be cool?
How can I turn from Africa and live?”
—Derek Walcott (b. 1930)
“I am convinced that the best service a retired general can perform is to turn in his tongue along with his suit, and to mothball his opinions.”
—Omar Bradley (1893–1981)
“Although I’ve risen! and my back is bold.
My tongue is brainy, choosing from among
Care, rage, surprise, despair, and choosing care.
I’m semi-splendid within what I’ve defended.”
—Gwendolyn Brooks (b. 1917)
