Detailed explanation-1: -Temperature receptors (e.g., thermoTRP channels) in skin nerve endings of a whole body are molecules of the physiological thermostats. The mechanism of the temperature comparison in the thermostats’ molecules is a phase transition of these ion channels at a set-point.

Detailed explanation-2: -A thermoreceptor is a sensory receptor or, more accurately, the receptive portion of a sensory neuron that codes absolute and relative changes in temperature, primarily within the innocuous range.

Detailed explanation-3: -Thermoreceptors. Thermoreceptors can be separated into receptors for warmth and cold detection.

Detailed explanation-4: -Thermoreceptors are nonencapsulated, free nerve endings that occupy areas approximately 1 mm in diameter. Cold thermoreceptors respond in the range of 5° C (41° F) to 40° C (104° F) relative to the normal skin temperature of 34° C (93.2° F) and fire most frequently at 25° C (77° F).

Detailed explanation-5: -Thermoreceptors give the body the ability to detect heat and cold in the environment. They exist throughout the skin to give the entire body its temperature sensing ability. More nerve endings exist in different parts of the body, which will also determine the sensitivity of the skin to temperature changes.
