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. (credit: Nate Steiner.

Pain Definition, Types, Causes, & Management Britannica

WebAll pain receptors are free nerve endings and are called nociceptors. These are part of the process that transmits the pain to the brain (the process of nociception ). Various sensory receptors found throughout the body react to a variety of stimuli, such as hot, cold, pressure and chemical, all of which can give the patient the subjective experience of pain. WebHigh-threshold receptors exclusively innervate organs from which pain is the only conscious sensation (i.e., ureter, kidney, lungs, heart), but are relatively few in organs that provide innocuous and noxious sensations (e.g., colon, stomach, and bladder), innervated mostly by low-threshold receptors. siematic houston
