Thermoceptor

Part of speech: noun

Definitions

1. A sensory nerve ending that responds to heat and allows an organism to perceive warmth or temperature changes in its surroundings
2. A specialized receptor in the skin or body that picks up thermal stimuli so the nervous system can register warmth
3. Any nerve receptor tuned to heat, giving living things the ability to sense how hot or warm their environment is

Etymology: "Thermoceptor" is built from two parts: "thermo-", from Greek "thermos" meaning "hot" or "warm", and "-ceptor", from Latin "ceptor", a receiver, taken from "capere", to take or seize. Put together, the word names a receiver of heat, a sensory structure that picks up temperature. The "-ceptor" ending is a much-used scientific suffix. Its pattern appears in words for other sensory or signal-receiving structures, so a reader who meets "thermoceptor" can pick up the sense of "receptor" and simply attach the heat element to it. The word is a modern technical coinage rather than something found in ancient texts; it was built on classical building blocks to name a specific biological function.
