The Integumentary System

An example of a first-degree contract is a mild sun contract, or a sudden, short come apart of heat. There is ordinarily no long-term fur victimize from first-degree destroy, but the skin changes color. Specific treatment for a first-degree burn exit depend on the age of the person and their general health, and mostly on the extent of the burn, the location of the burn, and its cause. First-degree burns usually heal on their own within a week. These burns should not be bandaged, but cold compresses potentiometer be applied or the injured area put down the stairs cold running wet to reduce heat in the tissues and therefore limit tissue damage. Lotions or ointments can be applied to restore moisture to the damaged skin.

Second-degree burns guide the epidermal and also the dermal layers of the skin (Berkow, Beers and Fletcher, 1997, 1336-1338; Second-Degree, 2003). The burn will show deep redness, and there whitethorn be acidulent of the skin. The burned area whitethorn be wet and shiny, and may appear white or discolored in an irregular pattern. It may also be swollen, and will be painful. Second-degree burns can be caused by scalding injuries, burns by open flames, and by the skin coming in contact with a heated up object.

Superficial second-degree burns usually heal in active three weeks if the wound is kept clean and protected (Berkow, Beers and Fletcher, 1997, 1336-1338; Second-degree, 2003). heavy second-degree burns may take longer to heal. A reinvigorated l

Third-degree burns are estimable thickness burns (Berkow, Beers and Fletcher, 1997, 1336-1338; Third-degree, 2003)). These types of burns destroy the entire epidermal and dermal layers of the skin. The skin of the burn has a dry, leathery appearance, and may be black, white, brown or yellow.

There will be swelling in the area of the burn, but there may be no pain because the nerve endings of pain receptors bear been destroyed. Large third-degree burns heal poorly and slowly without medical checkup attention. Because third-degree burns destroy the epidermis and hair follicles, new skin will not grow to replace that which was burned.

The stratum horny layer is composed of anucleate squamous cells, which are filled with keratin (Ross, Romrell and Kaye, 1995, 372). The plasma membrane of these cells is thickened and coated with a glycolipid that forms the major constituent of the water barrier of the skin in the deeper parts of this layer. Because the cells have no nucleus, they cannot divide and reproduce, so they cannot generate cancers. Cancers, by definition, are cursorily dividing, relatively undifferentiated cells. Stratum corneum cells cannot reproduce, and are highly specialized, and this is why no cancers originate from the stratum corneum.
