What is a Dermatology?, skin-anatomy, Trend Health

The skin is an important organ covering the surface of the body. Divided into two layers of tissue: epidermis and dermis. The outermost part of the epidermis is called the stratum corneum, which is composed of unshed dead cells and contains keratin. The bottom layer of the epidermis contains two main types of cells, which are basal cells and melanocytes.

The dermis is located under the epidermis and contains a series of skin appendages, such as hair follicles, hairs, fat glands, sweat glands, capillaries, nerve endings and receptors.

Hair follicles are located in the deeper layer of the dermis, and hair grows from the hair follicles. The sebaceous glands are connected to the hair follicles, and they continuously secrete sebum into the hair follicles. The lower part of the hair follicle is connected to a special smooth muscle (called erector pili). When the human body is subjected to strong external stimuli, such as sudden cold, fear, and anger, these muscles will contract to varying degrees, which is the so-called “(remarkable)”.

This situation is more obvious in some animals. Sweat glands are independent curved gland structures that open directly from the dermis to the surface of the epidermis. Below the dermis is the subcutaneous tissue, which is rich in fat, fibrous connective tissue, blood vessels and nerve threads.

Resist foreign pollutants

It plays an important role in protecting the human body and can resist damage from some foreign pollutants and microorganisms. Its dense structure can prevent the body’s water from evaporating and losing, and at the same time it can store the body’s heat energy.

Reduce UV damage

Basal cell through continuous replication, create new cells will gradually goes to the surface of the epidermis, to replace dead cells shed. Melanocytes secrete a chemical substance called melanin. The amount of melanin determines the skin color. It can reduce the damage of ultraviolet rays to the skin.

Regulate body temperature

Hair protects the body. The sebum secreted by the sebaceous glands lubricates the hair and skin. Sweat helps the body expel excess heat. The tiny blood vessels under the skin can also regulate the storage and release of body heat due to their contraction or expansion.

Sensory function

Nerve endings and receptors give the skin a sensory function. Another function of the skin is to help make vitamin D.
