sensory receptors

Quick Reference

An anatomical structure composed of sensory nerve endings adapted to respond to specific stimuli (1) and to convert them into nerve impulses that are transmitted to other parts of the nervous system, the forms of energy to which they respond being light, kinetic energy, temperature, chemical reactions, in some species of fish electrical discharges, in some snakes infrared radiation, and in some birds and other species the Earth's magnetic field. See auditory receptor, cold spot, cone, electroreceptor, free nerve ending, Golgi tendon organ, gustatory receptor, hair cell, infra-red vision, magnetic sense, mechanoreceptor, Meissner's corpuscle, Merkel cell, muscle spindle, nocireceptor, olfactory receptor, osmoreceptor (1, 2), otolith, Pacinian corpuscle, pain receptor, photoreceptor, pressure receptor, rod, Ruffini corpuscle, saccule, tactile receptor, taste bud, temperature receptor, touch receptor, utricle, warm spot. See also chemoreceptor, contact receptor, cutaneous sense, distance receptor, exteroceptor, interoceptor, proximoreceptor, receptive field, sense organ, somatic receptor, telereceptor, transducer. Also called a receptor. [From sensory + receptor, from Latin recipere, receptum to receive, from re- back + capere, ceptum to take]
