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 .
I think there should be some mention about the healing process and cycle of taste buds, I'm sure many people look at this page because they scalded their tongue, or otherwise damaged their taste buds. looking around, I found this: post which links to some other good pages on taste buds. Essentially, the cells are replaced every 1-2 weeks.
The two ion channels now suggested to contribute to sour taste are ASIC2 and TASK-1. The diagram depicts the signal transduction pathway of the sour or salty taste. Object A is a taste bud, object B is a taste receptor cell within object A, and object C is the neuron attached to object B. I. Part I is the reception of hydrogen ions or sodium ...
Taste bud. The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste (flavor). [1] Taste is the perception stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue.
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 ...
The gustatory cortex is the primary receptive area for taste. The word taste is used in a technical sense to refer specifically to sensations coming from taste buds on the tongue. The five qualities of taste detected by the tongue include sourness, bitterness, sweetness, saltiness, and the protein taste quality, called umami.

Taste records flavoring of food and other materials that pass across the tongue and through the mouth. Gustatory cells are located on the surface of the tongue and adjacent portions of the pharynx and larynx. Gustatory cells form on taste buds, specialized epithelial cells, and are generally turned over every ten days. From each cell, protrudes ...
