Fingers and lips are two body areas that are particularly sensitive to touch.
Why are some areas more sensitive than others?
The sensitivity of different body areas to touch varies based on the concentration of touch receptors. According to the reference provided, areas with a higher density of touch receptors are more sensitive.
Touch Receptor Density
- Fingers and Lips: High density of touch receptors.
- Back: Lower density of touch receptors.
This difference in receptor density explains why we are more sensitive to touch on our fingers and lips compared to our backs.
