If a single spinal nerve is cut, the area of tactile loss is always greater than the area of loss of painful sensations, because
Correct Answer: Degree of overlap of fibres carrying tactile sensation is much less
Description: Receptor field overlapping is lowest for temperature. Tactile receptor fields overlap higher than temperature. Highest overlapping is for pain. Temperature < Touch < Pain.
So the inverse will be true for loss of sensation. Loss of sensation highest in Temperature since it has no overlapping. And the loss of sensation will be lowest for pain.
