Document Summary

We have 5 main tastes, each taste depends on a specific receptor that is localized on the tongue. Bitter, salty, sweet, sour, and umami (ability to taste glutamate). The gustatory system consists of taste receptor cells in taste buds. Taste buds, in turn, are contained in structures called papillae. Taste buds are concentrated anteriorly (front) on the tongue. Taste buds can be fungiform (anterior), foliate (side), and circumvallate (back): in each taste bud are the 5-receptor cells that can detect each taste. Each taste can be detected anywhere on the tongue. Each taste bud has cells specialized for each of the 5 tastes: mostly on anterior part of tongue. Fungiform papillae are mushroom-shaped structures located on the tip and sides of the tongue, which contain taste buds. Foliate papillae are folded structures at the back of the tongue on both sides, which contain taste buds.
