Thermal nociceptors are activated by noxious heat or cold at several temperatures. You'll find precise nociceptor transducers which have been answerable for how and if the particular nerve ending responds towards the thermal stimulus. The main to be found was TRPV1, and it's got a threshold that coincides with the warmth pain temperature of 43 °C. Other temperature in the warm–very hot range is mediated by multiple TRP channel.
