Potentially damaging mechanical, thermal, and chemical stimuli are detected by nerve endings called nociceptors, which are found in the skin, on internal surfaces such as the periosteum, joint surfaces, and in some internal organs. Some nociceptors are unspecialized free nerve endings that have their cell bodies outside the spinal column in the dorsal-root ganglia. Other nociceptors r… WebNociceptive pain occurs in 5 phases: 1) Transduction, 2) Conduction, 3) Transmission, 4) Modulation, 5) Perception.
