Preksha Dhyaca :
The patterns (called fingerprints) are so characteristic for each individual that they can be used as means of identification.
Accessory Organs of the Skin Varied functions of the skin are abetted by accessory organs such as hair and nails. More important but less visible are sebaceous and sweat glands. Hair
No human is totally hairless. A prominent growth is the hair of the scalp. It protects the head and brain proteins from the barmful effects of the Sun's rays and excessive heat. Facial and chest hairs (on males) are signs of sexual maturation. A hair can regrow even if cut, shaved or plucked out. The colour of the hair depends on the amount of melamin present. White hair is the result of the Teplacement of melamin by tiny air bubbles. Each hair consists of a root and a shaft. Nails
The nails form a protective covering on the dorsal surfaces of the fingers and toes. Their appearance may give an indication of general body health. Each nail consists of a root and a body. It takes about six months for the nail to grow out from its base to the finger tip. Sebaceous glands
These are microscopic structures secreting an oily substance-sebum, which forms a protective film over hair and skin. Sweat glands
These are distributed over most of the body surface but are more abundant in the armpits, the palms, the soles and the forehead.
SWEAT is a clear watery fluid containing 0.5 percent of solids consisting of sodium chloride, other mineral salts and urea. Sweating is one of the mechanism by which the body regulates its temperature. The secretion of sweat is controlled by hypothalamus via the sympathetic nervous system.
