Document Summary
Pain serves as a sophisticated warning system that tells us when something might be internally wrong or when an external stimulus might be dangerous, enabling us to defend our bodies as quickly as possible. The human sense of touch is mostly housed in the largest and heaviest of the sense organs . The skin: touch receptors are embedded all over the body, in both hairless and hairy skin, they"re also found within our mouths and our muscles, tendons, and joints. Processing subsystems that each contribute to the overall sense of touch.
