<prompt> If a single spinal nerve is cut, the area of tactile loss is always greater than the area of loss of painful sensation, becauseTactile information is carried by myelinated fast conduction fiberTactile receptors adapt quicklyDegree of overlap of fibers carrying tactile sensation is much lessIn the primary sensory cortex tactile sensation is represented on a larger area  <response>: Ans. c Degree of overlap of fiber carrying tactile sensation is much lessRef: Ganong, 25th edp.160The degree of overlap of fibers carrying pain is much greater than tactile sensationSo, the area of tactile loss is always greater for tactile sensation
