The Integumentary system consists of the skin, hair, nails, glands, and nerves. The integumentary system also consists of 3 layers, the epidermis, dermis (cutis) and the subcutaneous (hypodermis). The epidermis is the outermost covering of epithelial cells with no blood vessel, dermis is composed of fibrous connective tissue and contains two sub layers called papillary layer and reticular layer, and subcutaneous lies under the dermis and consists mostly of connective tissue. This is found between the dermal and the inner organ. Lesions are changes in the skin structure caused by a disease processes. Lesions can also be called skin signs because of the visual abnormalities of the skin surface. These lesions have two categories which are primary skin lesion and secondary skin lesions. The two lesions are based on the texture and the color of the skin. Primary lesions are caused by external and internal conditions. Secondary lesions results in infection, trauma and other conditions.
