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)
“The eye of man hath not heard, the ear of man hath not seen, man’s hand is not able to taste, his tongue to conceive, nor his heart to report what my dream was!”
—William Shakespeare (1564–1616)
“The afflicted are not listened to. They are like someone whose tongue has been cut out and who occasionally forgets the fact. When they move their lips no ear perceives any sound. And they themselves soon sink into impotence in the use of language, because of the certainty of not being heard.”
—Simone Weil (1909–1943)
