Skin Anatomy and burn Classes

Dr. Bassem Alaa El-din

Skin

• The skin is the largest organ of the body, with a total area of about 20 square feet. The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold.

• Skin has three layers:• The epidermis, the outermost layer of skin, provides a waterproof

barrier and creates our skin tone.• The dermis, beneath the epidermis, contains tough connective

tissue, hair follicles, and sweat glands.• The deeper subcutaneous tissue (hypodermis) is made of fat and

connective tissue.• The skin’s color is created by special cells called melanocytes, which

produce the pigment melanin. Melanocytes are located in the epidermis.

Skin burn Classes

Skin Burns

• First-degree burns are red and painful. They swell a little and turn white when you press on them. The skin over the burn may peel off in a day or two. These are the least severe type of burn, affecting only the outer layer of skin.

• Causes: Sunburn and hot liquids
