THE SKIN ESSENTIALS IN A NUTSHELL


The skin is a unique and remarkable organ that is the outer covering of the body. One square inch of skin contains millions of cells as well as many specialized nerve endings for sensing heat, cold, and pain. The skin is nourished by blood vessels and contains numerous oil glands, hair follicles, and sweat glands. The skin protects the vital organs and serves as a heat regulator ––sweating when you are hot allows the water to evaporate and cool the skin. When your body is chilled, the vessels become narrowed and decrease the flow of blood through the skin to reduce heat loss. The skin’s texture gives
a great deal of information about a person’s general health.

ELEMENTS OF THE SKIN


Epidermis
The outer layer of the skin is made up of outer dead skin cells and deeper living cells.

Dermis
The dermis is found beneath the epidermis and makes up 90 percent of the skin. The melanocyte within the epidermis produces melanin giving color to the skin and helps protect it from ultraviolet light.


Cross Section of Skin


Subcutaneous
The epidermis and dermis sit on the subcutaneous layers, composed largely of fat, through which the blood vessels and nerves run. The roots of the oil and sweat glands are located here.

Sebaceous Oil Glands These are distributed throughout the skin but are mostly concentrated in the scalp, face, mid-chest, and genitals. They are attached to the hair follicles and secrete an oily substance (sebum) that lubricates and protects the skin.

Sweat Glands
These glands are distributed throughout the body but the greatest number are found in the palms, soles of the feet, forehead, and underarms.
