The skin covers the surface of the body and consists of two main layers, the surface epithelium or epidermis and the subjacent, connective issue layer - the corium or derma. Beneath the latter is a loose connective tissue layer, the superficial fascia or hypodermis, which in many places is trans formed into subcutaneous fatty tissue. The hypodermis is connected with underlying deep fasciae, aponeuroses or periosteum. The skin is continuous with several mucous membranes through mucocutaneous junctions, the most important, of which are the vermilion border о the lip, the vulva and the anus. The skin protects the organism from injurious external influences, receives sensory impulses from the outside, excretes various substances and, in warm-blooded animals, helps to regulate the temperature of the body. The skin is provided with hairs, nails, and glands of various kinds. There is a sharp boundary between the epithelial and the connective tissue portions of the skin, but not between the derma and the hypodermis here the fibers of one layer pass directly over into the other. The surface of contact between the epidermis and the derma is uneven in most places. It appears as a straight line only on the forehead, the midline of the perineum and scrotum, and the external ear. In most of the skin of the body the outer portion of the derma, is provided with a series of irregular ridges called papillae; into the spaces between them the lower layers of the epidermis intrude.
