WebMechanisms of Mammalian Pain Systems. Pain receptors (nociceptors) are widely distributed in the skin and other tissues. Nociceptors are free nerve endings of sensory Aδ and un-myelinated C nerve fibers, which respond to tissue damage. Stimulation of the nociceptors by tissue damage results in action potentials in the peripheral nerve fibers.
