Skin with sweat droplets. Coloured scanning electron micrograph (SEM) of the skin surface of the back of a human hand, showing sweat droplets. Droplets (blue) are emerging from the entrance of many eccrine (exocrine) sweat glands that lie in the dermis of the skin. This sweat has appeared after one hour of exercise. There is a small skin lesion (at above centre) on the furrowed surface of the skin; at extreme lower right is the shaft of a hair. Secretion of sweat, mostly in the form of sodium chloride, is a method of controlling body temperature. This SEM was taken from a skin cast. Magnification: x15 at 5x7cm size.
