Cutaneous receptors of the skin
WebThe enhanced pain sensation at the site of skin injury (primary hyperalgesia) is thought to result from an enhanced responsiveness (sensitization) of cutaneous nociceptors. Hyperalgesia in a large area of uninjured skin surrounding the injury site (secondary hyperalgesia) is most likely due to sensitization of neurons in the central nervous system. WebA cutaneous pain receptor is a sensory receptor located in the skin that is responsible for detecting pain stimuli. Based on the information you provided, it can be classified as an exteroceptor because it responds to stimuli that originate from outside the body, a general somatic receptor because it is distributed throughout the body, and a ...
