The type II taste bud cells make up about another third of the cells in the taste bud and express G-protein coupled receptors that are associated with chemoreception. They usually express either type 1 or type 2 taste receptors, but one cell might detect different stimuli, such as umami and sweetness. [5]
The diagram above depicts the signal transduction pathway of the sweet taste. Object A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane. II.
The myth of the tongue map: that 1 tastes bitter, 2 tastes sour, 3 tastes salty, and 4 tastes sweet. The tongue map or taste map is a common misconception that different sections of the tongue are exclusively responsible for different basic tastes. It is illustrated with a schematic map of the tongue, with certain parts of the tongue labeled ...
The tongue is equipped with many taste buds on its dorsal surface, and each taste bud is equipped with taste receptor cells that can sense particular classes of tastes. Distinct types of taste receptor cells respectively detect substances that are sweet, bitter, salty, sour, spicy, or taste of umami. [15]

The word “acid” is a little harsh, but so are vinegar and citrus juices, which are, umm, acidic. The vinegar you choose is totally up to your taste buds.
The mouth, throat, larynx, and esophagus all have taste buds, which are replaced every ten days. Each taste bud contains receptor cells. [21] Afferent nerves make contact with the receptor cells at the base of the taste bud. [23] A single taste bud is innervated by several afferent nerves, while a single efferent fiber innervates several taste ...
