Part 2
The skin is an organ composed of three anatomical layers: epidermis, dermis, and hypodermis. These anatomical layers together function to provide the body with a protective barrier, body temperature regulation, sensation, excretion, the outer layer of skin …show more content…
Unlike the skin that covers the rest of our bodies, friction ridge skin is corrugated: a network of raised areas of flesh called ridges and the recesses between called furrows. Lining the tops of the ridges are thousands of sweat pores that, in most people, regularly emit perspiration. Biologically, friction ridge skin improves our ability to grip and gain traction. But, when it comes in contact with a surface, there is usually a transfer of perspiration and other contaminants the ridges have picked up (oil from hair bearing portions of our body, grease from food, etc.) onto the surface. Friction ridge skin identification or exclusion is based on permanency and uniqueness, two principles firmly established by the biological sciences, most notably embryology, genetics, and anatomy. Permanency pertains to the fact that friction ridge skin, once formed and barring serious injury it will not undergo any fundamental natural change. It grows and ages as the individual grows and ages, and can become worn due to work, but the ridge characteristics used in identification will not change location or position and will continue to exactly reproduce itself. Uniqueness is created during the formation of friction ridge skin during fetal development by a wide range of random forces: timing events, stresses placed on fetal hand and feet tissue as it grows, distribution of cells,
