Summary Introduction
To review:
The pathway shows response via signal generation by taste bud receptors.
Introduction:
Taste receptors are formed from a part of a structure called taste bud. These taste receptors are concentrated in the mouth. Humans have about 10,000 taste buds scattered over the tongue, the roof of the mouth, as well as throat. Recent research concludes that the classes of receptors may all have subtypes, each binding a specific molecule within that class.
