ANATOMY

Detailed explanation-1: -A thermoreceptor is a non-specialised sense 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-2: -Thermoreceptors respond to temperature changes. The three classifications of sensory receptors are based on their location. Enteroceptors respond to stimuli from outside the body and are usually near or upon the body surface.

Detailed explanation-3: -Thermoreceptors primarily sensitive to cold have increased activity at temperatures cooler than the neutral skin temperature (about 34 °C [93 °F]), and thermoreceptors primarily sensitive to warmth have increased activity at temperatures warmer than neutral skin temperature.

Detailed explanation-4: -Thermoreceptors are specialized parts of neurons, or nerve cell endings, that give the body the ability to detect changes in temperature. Temperature is defined as the relative degree of heat that is present in the environment. Thermoreceptors give the body the ability to detect heat and cold in the environment.

Detailed explanation-5: -ThermoTRP channels are multimodal receptors that respond to both temperature and chemical compounds. For example, TRPM8 channels are sensitive to low temperatures, menthol, and icilin.
