Thermoreceptors in hypothalamus

WebbThe thermopeceptors, located at the depth of 2–2.5 mm, during cooling or heating the skin surface (by 10°C with the rate of 1–2°C/s) began to respond in a large latent period of 20–60 s. This corresponded by the time to the beginning of the temperature changes in this very layer of the skin. WebbThermoreceptors are of several types. Those in the hypothalamus, spinal cord, and gut apparently monitor body temperature and are involved in autonomic functions. Those in the skin, the cutaneous temperature receptors, mediate localized and general temperature sensations in humans and participate in the autonomic processes achieving endothermy …
