Peripheral nociception
WebNeuropathic pain has been defined by the IASP as “pain arising as a direct consequence of a lesion or disease affecting the somatosensory system”. It requires damage to … WebNociceptors are peripheral cell nerve endings that initiate pain sensation, respond to a noxious stimulus (thermal, mechanical, or chemical) which in turn trigger action potential to the spinal cord and to higher centers. It is divided into A-delta and C fibers.
