Taste checking regions are called taste buds .
Your taste buds allow your brain to register taste. The taste buds are in the tongue, and they connect with nerves that transmit the taste into electronic signals so you can experience it. Different parts of your tongue taste different tastes.
Taste occurs over the whole surface of the tongue. Certain areas of the tongue may be more sensitive to one of the five tastes humans can register: sweet, bitter, salt, sour, and savory (like garlic).

On average, the human tongue has 2,000-8,000 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.
