WebThermoreceptors detect temperature changes. We are equipped with thermoreceptors that are activated by cold conditions and others that are activated by heat. Warm receptors will turn up their signal rate when they feel a warming or heat transfer into the body. Cooling or heat transfer out of the body results in a decreased signal rate. WebThermoreceptors.

WebThermoreceptors. Somatosensory receptors, and all these different categories, can be found in a number of places throughout the body. One of the big places is in the skin. Here's a drawing of the skin. This is the very surface of the skin, with the hair coming out of it, and then here are the deeper layers of the skin. WebThis experience of pain in relation to temperature is called thermal nociception and involves a different set of distributed receptors. Figure 2.2. Thermal Receptors. Thermal receptors are sparsely distributed in the skin. Some regions of the skin have no thermal sensation for non-damaging (non-noxious) stimuli.
