WHY IS THE TASTE RECEPTORS IN TONGUE CONCENTRATED MORE IN SOME PLACES?

Taste buds are special structures that help detect tastes. We all have about 10,000 taste buds, mainly on the tongue with a few at the back of the throat and on the palate. Taste buds surround pores within the protuberances on the tongue's surface and elsewhere.

A taste bud is a taste receptor. There are four types of taste receptors: (1) sweet, as produced by table sugar; (2) sour, as produced by vinegar; (3) salty, as produced by table salt; and (4) bitter.
The five sensations are felt on all areas of the tongue, not just on a certain spot. Though certain areas of the tongue are much more receptive to flavor due to the high concentration of taste receptors.
