Human Skin And Its Associated Parts

Human skin and its associated parts of hair, nails, sweat pores and glands, blood vessels, melanocytes and nerve endings, is the largest organ in the human body.

The skin of an average adult has a surface area of between 16 and 21 square feet (1.5-2.0 sq. metres) and is around one tenth of an inch thick (2-3mm).

Skin Function

Skin guards and protects the underlying muscles and organs from organisms or substances that cause disease, provides body temperature control and insulation and defends against damaging ultra violet radiation in sunlight.

It also functions as a water resistant obstacle preventing essential nutrients from being washed out of the body and as a signal or warning when the nerve endings react to touch or pressure, hot, cold or injury.

What Do Melanocytes Do?

Melanocytes produce melanin, the pigment responsible for the colour of the skin, eyes and hair.

Skin is probably the most vulnerable area of the body to attacks by injury, disease and other ailments so, because it is so visible and susceptible, great care should be taken to preserve it from damage.

Sadly it is also the skin that shows the first signs of aging so early attention to skin care is a must if you want to retain that youthful glow for as long as possible.
