Sensory neurons responding to stimuli capable of producing tissue damage are termed nociceptors and have free nerve endings of either myelinated small-diameter (Aδ) or unmyerlinated (C) fiber axons. They display either single or multiple receptive fields. Nociceptive afferents supply skin, subcutaneous tissue, periosteum, joints, muscles and viscera. Nociceptors also innervate vessels, meninges, and nervi nervorum.Skin, subcutaneous tissue and fascia are supplied by mechanical nociceptor afferents and heat and cold nociceptors; most of Aδ and C nociceptors in primates are mechano-heat sensitive and respond to chemical stimuli as well and are referred to as polymodal nociceptors.
