chemoreceptor reflex definition
A chemoreceptor, also known as chemosensor, is a sensory receptor that transduces a chemical signal into an action potential. In more general terms, a chemosensor detects certain chemical stimuli in the environment. Examples of direct chemoreceptors include: 2  Taste buds in the gustatory system: The primary use of gustation as a type of chemoreception is for the detection of tasteants. 3  Aqueous chemical compounds come into contact with chemoreceptors in the mouth, such as taste buds on the tongue, and trigger responses.
