Sense of Taste
Friday May 30, 2008
The sense of taste is mediated by groups of cells called taste buds.
Taste buds sample oral concentrations of a large number of small molecules and report a sensation of taste to centers in the brainstem.
Taste buds are most prevalent on small pegs of epithelium on the tongue called papillae.
The taste buds themselves are too small to see without a microscope, but papillae are readily observed by close inspection of the tongue's surface.
Once taste signals are transmitted to the brain, several pathways are activated that are important to digestive function. For example, tasting food is followed rapidly by increased salivation and by low level secretory activity in the stomach.

i want to learn more of test buds
Send me all endocrine physiology as well as CNS physiology and more details on the sense of taste
i want 2 know all about test buds
