Taste Bud
Taste buds contain the receptors for taste. They are located around the small structures on the upper surface of the tongue, soft palate, upper esophagus and epiglottis, which are called papillae. These structures are involved in detecting the five (known) elements of taste perception: salty, sour, bitter, sweet, and umami. Via small openings in the tongue epithelium, called taste pores, parts of the food dissolved in saliva come into contact with taste receptors. These are located on top of the taste receptor cells that constitute the taste buds. The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves.
On average, the human tongue has 2,000–8,000 taste buds.

Famous quotes containing the words taste and/or bud:
“Come, give thy soul a loose, and taste the pleasures of the poor.
Sometimes ‘tis grateful for the rich to try
A short vicissitude, and fit of poverty:
A savory dish, a homely treat,
Where all is plain, where all is neat,
Without the stately spacious room,
The Persian carpet, or the Tyrian loom,
Clear up the cloudy foreheads of the great.”
—Horace [Quintus Horatius Flaccus] (65–8)
“And yet no greater, but more eminent,
Love by the spring is grown;
As, in the firmament,
Stars by the sun are not enlarged, but shown,
Gentle love deeds, as blossoms on a bough,
From love’s awakened root do bud out now.”
—John Donne (1572–1631)
