In physiology textbooks discussing about sensation, two-point discrimination using pins (or any pointed object) is used to demonstrate which part of the body has more nerve endings. Example, the skin at the back will detect two pin points placed about 0.5 cm as one point, while the skin on your fingertip will recognize these two pin points distinctly.
