a branch of medicine dealing with the skin, its structure, functions, and
diseases (from Greek derma, "skin"), as well as its appendages (nails,

Hair |
| Hair
hair itself is dead, but it's produced by living cells. Those cells are
epidermal in nature and origin, and the hair, like the other adnexa of the skin,
is epidermal in nature. Specialized keratinocytes at the base of the hair
produces it, and the pigmentation in hair comes from melanocytes, just as the
pigmentation of the skin does |
| Hair
hair is largely made up of a protein called keratin. Cells in the hair follicle
regularly produce the keratin and other proteins that become incorporated into
the hair shaft. Coloration comes from melanocytes which produce the brown
pigment melanin |
| Hair
the outer layer of your skin is called the epidermis, and it's full of holes. There are pores, sweat
glands, and hair follicles, which are the pits from which hairs grow. Follicles extend well down into the dermis, or 'underneath skin', and
grow from a bulb, or root |

| Hair structure and life cycle
each strand of hair consists of three layers: an innermost layer or medulla which is only present in large thick hairs, the middle layer known as the cortex. The cortex provides strength and both
the color and the texture of hair, the outermost layer is known as the cuticle. The cuticle is thin and
colorless and serves as a protector of the cortex |

| Skin anatomy
the skin — the largest organ of the body — is made up of a thin outer layer (called the epidermis) and a thicker outer layer
(called the dermis) |
| Skin, hair, and nails
the skin is the largest organ of the body, with a surface area of 18 square feet. Its two main layers are the
epidermis (outer layer) and dermis (inner layer). The epidermis has several strata (layers) that contain four cell types. Keratinocytes produce keratin, a
protein that gives skin its strength and flexibility and waterproofs the skin surface. Melanocytes produce melanin, the dark pigment that gives skin its color,

the epidermis is the epithelial portion, in which cellular proliferation and
renewal takes place, the dermis is the connective tissue layer underlying the
epidermis. It's here you will find the blood vessels which serve the nutrient
needs of the deep epidermis, as well as the nerve fibers that carry the signals
from receptors located just under the epidermis |
| Skin
the skin is the largest connective tissue in the body. It makes up about 10% of the total body weight. The skin has many roles, particularly in:
protection – the skin is a blockage from the external surrounding, touch – sense organs for touch, pressure, pain
and temperature, regulation of the physiological surrounding – the skin helps the body maintain a normal body temperature, accumulate
water, and get rid of toxic materials in the process of sweating, ppt file |
