Touch sensor. Light micrograph of sectioned Pacinian corpuscle (large circle,centre),a sensory receptor for touch. The corpuscle consists of nerve endings surrounded by 'onion-skin' membrane layers. The nerve cells are stimulated when the membranes are deformed by changes in pressure. Pacinian corpuscles are especially sensitive to vibration. They are found in skin & some internal membranes.
