Anatomy and Physiology of the Skin

What is the physiological process of the skin?
Thermoregulation: Skin plays an important role in maintaining body temperature through a process called thermoregulation.
The two primary mechanisms involved in thermoregulation are sweating and blood circulation.
To dissipate excess heat, the blood vessels in the skin dilate which results in increased blood flow.
What are the 4 functions of the skin anatomy?
Reduces harmful effects of UV radiation.
Acts as a sensory organ (touch, detects temperature).
Helps regulate temperature.
An immune organ to detect infections etc.
What is the anatomy and physiology definition of dermis?
The dermis is a connective tissue layer sandwiched between the epidermis and subcutaneous tissue.
The dermis is a fibrous structure composed of collagen, elastic tissue, and other extracellular components that includes vasculature, nerve endings, hair follicles, and glands.
Skin that has four layers of cells is referred to as “thin skin.” From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum.
Most of the skin can be classified as thin skin. “Thick skin” is found only on the palms of the hands and the soles of the feet.

It is made up of three layers, the epidermis, dermis, and the hypodermis, all three of which vary significantly in their anatomy and function. The skin's structure is made up of an intricate network which serves as the body's initial barrier against pathogens, UV light, and chemicals, and mechanical injury.
