Taste bud
Taste bud
Taste bud (/teɪst bʌd/) is a specialized sensory organ that is primarily associated with the sense of taste.
Etymology
The term "taste bud" is derived from the English words "taste," which refers to the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, and "bud," which refers to a small protuberance.
Definition
A taste bud is a small, flask-shaped organ that is found on the surface of the tongue, the roof of the mouth, and the lining of the throat. Each taste bud contains a set of elongated taste receptor cells, with each cell equipped with a taste pore via which it interacts with the oral environment.
Function
Taste buds are responsible for detecting the five elements of taste perception: sweet, sour, bitter, salty, and umami. They transmit taste signals to the brain through a complex network of neurons.
