2.The structure of the skin and the ancillary organs of the skin
Understand the structure of the skin.The skin consists of the epidermis,dermis,subcutaneous tissue and skin accessories, and is connected to the tissue below it.
Epidermis: is an epithelial tissue, located in the outermost layer of the skin, is the gateway to daily contact with the outside world, but also the use of cosmetics.The epidermis can be divided into 5 levels from the outside to the inside: cuticle layer, transparent layer, granular layer, spiny layer, basal layer.
Dermis:connective tissue, located below the epidermis, interspersed with the epidermis canine teeth.The dermis is mainly composed of collagen fibers, elastic fibers, reticular fibers and matrix. They play a decisive role in the size and luster of the skin's elasticity.
Subcutaneous tissue: also known as the subcutaneous fat layer,its thickness is related to a person's nutritional status, gender, age and location. A person's fat and thinness mainly depend on the amount of subcutaneous fat.
Accessory organs of the skin
Sweat glands:one is a small sweat gland, which excrete sweat, moisturizes the skin, and does not dry the skin;the other is a large sweat gland, whose secretions are thicker, and the secretions themselves are odorless. After decomposition by bacteria, they have a bad smell, commonly known as body odor.
Sebaceous glands: Sebaceous glands secrete sebum to lubricate the skin and hair,but secrete too much in some parts, which can easily lead to acne, dermatitis and seborrheic alopecia.
Hair:there is hair growth on the surface of the human body except the palms, the soles of the feet, etc.; the hair is composed of keratinized epidermal cells, divided into two parts: hair rods and hair roots;the cross-section of the hair can be divided into three layers, from the outside to the inside, followed by the epidermis layer, fur layer and hair medulla;the hair epidermis is composed of transparent keratinized cells arranged like fish scales, also known as hair protective film, which can make the hair shine; the cells of the cortex and medulla contain pigment particles, and the color of the hair depends on the content of pigment particles.
