taste receptor
Quick Summary
A taste receptor is a cell that interacts with chemicals from food and other sources to enable the perception of taste. These receptor cells are found in groups of 50 to 150, forming what is known as a taste bud. In terrestrial vertebrates, including humans, taste buds are primarily located on the tongue, but can also be found on the palate and epiglottis.
Taste buds connect to afferent sensory neurons, which transmit taste information to the brain via three different nerves: the facial nerve, the glossopharyngeal nerve, and the vagus nerve. These taste receptor cells are continuously renewed throughout an organism's life. Humans typically have between 2,000 and 8,000 taste buds, though this number can vary significantly, contributing to individual differences in taste perception. The five recognized tastes are sweet, salty, sour, bitter, and umami.
