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:
“These things are not inscribed in tablets, not sealed in the folds of papyri, but you hear them clearly from the tongue in a free mouth.”

“The master, the swabber, the boatswain and I,
The gunner and his mate,
Loved Mall, Meg, and Marian and Margery,
But none of us cared for Kate;
For she had a tongue with a tang,
Would cry to a sailor, ‘Go hang!’
She loved not the savour of tar nor of pitch,
Yet a tailor might scratch her where’er she did itch:
Then to sea, boys, and let her go hang.”
—William Shakespeare (1564–1616)
