Thermoreceptors are specialized sensory receptors that respond to changes in temperature. They are primarily located in the skin, but also found in other tissues, including internal organs. Thermoreceptors help the body detect thermal stimuli, allowing for the sensation of heat and cold, which is essential for thermoregulation and avoiding potential injuries from extreme temperatures. There are two main types: warm receptors, which respond to increases in temperature, and cold receptors, which react to decreases in temperature.
