Perception of temperature and role of the thermoreceptors

WebThe concept of thermoreceptors derives from studies of human sensory physiology, in particular from the discovery reported in 1882 that thermal sensations are associated with stimulation of localized sensory spots in the skin. Detailed investigations revealed a distinction between warm spots and cold spots—that is, specific places in the human skin … WebA delta type II fibers are fast-adapting while A delta type I and C fibers are slowly adapting. Modality. Free nerve endings can detect temperature, mechanical stimuli (touch, pressure, stretch) or danger (nociception). Thus, different free nerve endings work as thermoreceptors, cutaneous mechanoreceptors and nociceptors. dxwifi
