The subcutis, consisting of a network of collagen and fat cells, helps conserve the body's heat and protects the body from injury by acting as a "shock absorber." The subcutis is the deepest layer of skin. This layer also contains nerve endings that conduct pain and touch signals. The dermis is held together by a protein called collagen, made by fibroblasts. The dermis is the middle layer of the skin. The epidermis also contains melanocytes, which are cells that produce melanin (skin pigment). This layer is where new skin cells divide to replace the old cells that are shed at the surface. This layer is made up of living cells that are maturing and moving toward the surface to become the stratum corneum. As the outermost layer, it continuously flakes off. it keeps body fluid in while keeping external substances out. This layer is made up of cells containing the protein keratin. The epidermis is the thin, outer layer of the skin with many layers including: It is made up of several layers, with each layer having a specific functions: The skin is the largest organ of the body and has many important functions. These burns are from electrical current, either alternating current (AC) or direct current (DC). These burns are due to strong acids, alkalies, detergents, or solvents coming into contact with the skin or eyes.Įlectrical burns. These burns are due to prolonged exposure to ultraviolet rays of the sun, or to other sources of radiation such as X-ray.Ĭhemical burns. ![]() Hot metals, scalding liquids, steam, and flames, when coming into contact with the skin, can cause thermal burns. These burns are due to heat sources which raise the temperature of the skin and tissues and cause tissue cell death or charring. There are many types of burns caused by thermal, radiation, chemical, or electrical contact. Both infants and the older adults are at the greatest risk for burn injury. ![]() Scalding is the leading cause of burn injury for children. Smoking and open flame are the leading causes of burn injury for older adults. Burns are a type of painful wound caused by thermal, electrical, chemical, or electromagnetic energy.
