What is sensory receptors in physiology? Sensory receptors are specialised epidermal cells that respond to environmental stimuli and consist of structural and support cells that produce the outward form of the receptor, and the internal neural dendrites that respond to specific stimuli. The sensory function of the hand provides feedback to the brain for object recognition and protection as the hand interacts with its environment. By providing signals from the brain to the hand, the peripheral nerves provide the arm and hand with the senses of touch, pressure, temperature and pain. In physiology, sensory transduction is the conversion of a sensory stimulus from one form to another. Transduction in the nervous system typically refers to stimulus-alerting events wherein a physical stimulus is converted into an action potential, which is transmitted along axons towards the central nervous system for integration. It is a step in the larger process of sensory processing.
