Why are some places on your body more senssitive to touch than other?

Some areas of the body are more sensitive to touch due to a higher concentration of sensory nerve endings, which are responsible for detecting tactile stimuli. Regions like the fingertips, lips, and face have a greater density of these receptors, making them more responsive to touch. Additionally, the brain allocates more cortical area to process sensory input from these sensitive regions, enhancing their perception. This variation in sensitivity serves important functions, such as improving dexterity and facilitating social interactions.
