Document Summary
The surface of the hands and feet (volar skin) are covered with a series of ridges and furrows which allows for friction (gripping) between any other surface they contact. Commonly referred to as friction ridge formations. The ridges form unique patterns and arrangements allowing them to be used as a reliable means of identification. Friction ridges develop on the fetus birth and remain during life and even following death, until decomposition of the ridge skin. They are unique at a result of the growth rate and random fusing of the ridge unite (differential growth) Friction ridge are persistent throughout life except scarring/disease. Friction ridge pattern and the details of frictions ridges are never repeated. Despite millions of fingerprint and the advent of computer technology, no two fingerprint ever been found to be identical. The overall friction ridge pattern varies limits which for the classification of impressions. Ridge become visible spreading across fingers from.
