INTEGUMENTARY SYSTEM

The integumentary system is the name given for the skin, hair, nails, and glands covering the body. It also includes the eyes, the ears, the nose, and the mouth, all of which are a part of the body's sensory system. The world is perceived by means of coded messages (electrical impulses) sent to the brain by the sensory organs. Your perception is predominantly developed by means of the pattern of sound pressure entering the ears and the pattern of light entering the eyes. The senses of touch, taste, and smell, however, are also important to your perception of the world around you.
Fingernails are simply another form of skin. They are formed by a hardened protein called keratin, which has a high sulpher content. Contrary to popular belief, the calcium content of nails is very low.
Your fingernails are one of many indicators of health. Any dramatic changes in their texture, shape, color, or growth rate may be a signal to seek medical advice. Although a careful physician will always look at the nails, diagnosing or predicting any generalized ailment would be virtually impossible on the basis of the nails alone.

The skin has the largest surface area of any organ in the body and is the heaviest. On the surface are the sensitive papillae, and within are certain organs with special functions, the sweat glands, hair follicles, and sebaceous glands. The skin protects the internal organs of the body against infection, injury, and harmful sun rays. The skin also plays an important role in the regulation of body temperature. Although the skin of an average sized adult may weigh as much as twenty pounds, it is only paper thin in some places and not much thicker in others.
