Question

Quizplus · Accepted Answer

The differential sensitivity to pressure and touch across various parts of the body is primarily determined by the density of nerve endings in those areas and the size of the sensory cortex dedicated to processing sensations from those areas. Areas with a higher density of nerve endings, like the fingertips, are more sensitive, and the amount of sensory cortex devoted to a body part also influences sensitivity.
