chemoreceptor
Detects molecular signals
A chemoreceptor is a sensory cell or organ that detects chemical substances and triggers a physiological response.
Taste buds and olfactory neurons are chemoreceptors, translating chemical signals into the sensations of taste and smell.
Other chemoreceptors in the body monitor blood chemistry—detecting oxygen levels, carbon dioxide, or pH changes—and help regulate breathing and circulation.
