Introduction to Skin, Common Diseases And Care

I can say that the skin is the largest organ of the body that covers the entire surface of our body. It is composed of outer epidermis, an inner dermis, and a layer of subcutaneous fat below the dermis. An average skin is between 1 and 2mm thick. The skin of the eye is 0.5mm thick.

The outer Epidermis is made of the following

1. Cornified Layer.
2. Granular Layer:
3. Malpighian (Germinative) Layer.

The Inner Dermis compose mainly of connective tissue containing few cells, but many collagen and elastic fibres. These counter tensile strength and elasticity. Various structures are found in the dermis including:

1. Hair Follicles
2. Sebaceous Glands
3. The Capillaries in the Dermis
4. Sweat Glands
5. Sense Organs
6. Subcutaneous Fat

Functions of the Skin

• Protection: The skin protects the body against dehydration, invading microbes, mechanical damage, and damage due to ultra violent rays and poisonous chemicals
• Control Of Body Temperature: This plays a major role in temperature control (vasodilation and vasoconstriction).
• Response to Stimuli: This also contains receptor sensitive to heat cold touch and pressure.
• Excretory Organ: It has a minor role as an excretory organ. Urea and lactic acid are lost.
• Production of Vitamin D: The skin produces vitamin D in the fatty cells by using infra-red rays of the sun.
