Caloreceptor

/ˌkæl.ə.rɪˈsep.tɚ/ noun

Definition

A sensory nerve ending or receptor that detects and responds to heat or temperature changes in the body or environment.

Etymology

Compound of Latin 'calor' (heat) and 'receptor' (something that receives). Created in modern scientific terminology to describe heat-sensing biological structures discovered in the 20th century.

Kelly Says

Caloreceptors are why you can tell the difference between hot and cold water without looking—specialized nerve cells called thermoreceptors constantly send messages to your brain about temperature, but scientists are still discovering new types and how precisely they work.
