ABSTRACT
The skin is one of the largest organs of the human body. It serves a multitude of purposes: a barrier to infection; a controller of heat and fluid loss; and a sensory interface with the world. Its aesthetic qualities are of the utmost importance to the individual. The mobility and elasticity of the skin are necessary for joint movement, and its strength essential in areas where it is subjected to repeated minor trauma, especially in the hands and feet. The skin of each part of the body is modified to suit specific purposes; for example, the thick-ridged, sensitive and moist skin of the finger tip is ideal for gripping tiny objects, while the thin, compliant skin of the eyelid provides ideal mobility and protection of the globe.
