Everyone should bear in mind that such an extensive surface as the skin is not a mere covering; it is something else too—more important than a mere covering. It is one of the most important excretory organs of the body, especially in this tropical climate. Regarding its anatomy, it is made up of three layers, which are from above downwards—
- External, epidermal or scalp-skin layer; it contains no nerves or blood-vessels.
- Middle or colour bearing layer.
- Internal or Dermal or true skin layer. The last one is richly supplied with blood-vessels and nerves.
