These are clustered in taste buds and scattered in other areas of the body. Each taste bud has a pore that opens out to the surface of the tongue enabling molecules and ions taken into the mouth to reach the receptor cells inside. 1  salty. 2  sour. 3  sweet. 4  bitter.

A cell structure or site that is capable of combining with a hormone, antigen, or other chemical substance.tretch receptor-a receptor in a muscle that responds to stretching of the muscle tissue. papilla-a small nipple-shaped protuberance concerned with taste, touch, or smell; the papillae of the tongue. sensory system-the body's system of sense organs.
