("Anatomy & Physiology of Adult Friction Ridge Skin") The ridges and furrows on the surface of the friction ridge skin are solidly established in the dermis by primary ridges and secondary ridges. The primary and secondary ridges are interlocked with the dermis to offer support and strength to the friction ridge skin. ("Anatomy & Physiology of Adult Friction Ridge Skin") Friction ridge skins are comprised of sweat glands, epidermis, dermis, dermal papillae, primary ridge, secondary ridge, and pores. ("Anatomy & Physiology of Adult Friction Ridge Skin") Although the skin creates several appendages such as: hair, nails, sweat glands; the eccrine sweat gland is the only appendage of the friction ridge skin. Eccrine sweat glands are discovered everywhere throughout the body surface and function in thermoregulation. ("Anatomy & Physiology of Adult Friction Ridge Skin") The sweat glands of the palms and soles are bigger, more dynamic, and denser than in any other part of skin. Friction ridge skin persists because of physical attachments in the skin and the regulation of differentiation and of keratinocyte production.

(Jones, 2006) To determine whether two or more fingerprints match, examiners must go beyond these common ridge patterns and focus on the complex details of ridges that divide, cross, and terminate. (Jones, 2006) The persistent nature of the friction ridge skin makes it an ideal anthropological element to use as a method for identifying people. Furthermore, the structure of the skin provides a mechanism to depict distortion. The variation in the presence of friction ridge impressions is because of the flexibility of the skin. The skin distributes pressure into the more flexible furrows and offers insightful knowledge during the analysis of friction ridge impressions. ("Anatomy & Physiology of Adult Friction Ridge Skin") Scars continue for a similar reason that the friction ridge persists: attachment sites and direction or regulation of keratinocyte mitosis. ("Anatomy & Physiology of Adult Friction Ridge Skin") The utilization of scars in the correlation of friction edge impressions has a similar basis, and takes after a similar application, as the utilization of friction ridges. When the impression of the skin is made, the elements of the scar will be replicated at different levels of clarity. ("Anatomy & Physiology of Adult Friction Ridge Skin”) The clarity of the detail in the impression may
