Which of the following correctly identifies the layers of skin and fat from the outermost layer to the innermost layer?
Epidermis, dermis, subcutaneous
The epidermis, dermis, and subcutaneous layer are the three main layers of the skin.
The epidermis is the outermost layer of the skin and serves as a protective barrier against the environment. It also regulates the exchange of fluids and gases between the body and the outside world. The epidermis is composed of various types of cells, including keratinocytes, melanocytes, and Langerhans cells.
The dermis is the middle layer of the skin, located beneath the epidermis. It is composed of connective tissue and contains blood vessels, nerves, hair follicles, and sweat glands. The dermis provides the skin with structural support and allows for the movement of the skin.
The subcutaneous layer, also known as the hypodermis, lies beneath the skin and above the muscle and bone beneath. It is composed primarily of fat cells and connective tissue and functions to provide insulation and absorb shock.
Together, these three layers of the skin work to protect the body from damage, regulate temperature, and provide sensation to the outside world.
