cold receptor

cold receptor

a sensory structure that responds particularly to cold and sometimes to pressure. Such receptors occur in the skin of vertebrates, and in humans are more abundant and occur more superficially than warm receptors. fibres from cold receptors are active between 10° and 40 °C, with a maximum firing frequency between 20° and 34 °C.
