What are the three layers of the skin?

The three layers of the skin are correctly identified as the Epidermis, Dermis, and Subcutaneous layers.

The epidermis is the outermost layer of the skin. It serves as a protective barrier and is responsible for skin tone and resilience. This layer contains several types of cells, including keratinocytes, which produce keratin, a protein that helps waterproof the skin.

Beneath the epidermis lies the dermis, which contains connective tissue, blood vessels, and nerve endings. This layer is crucial for skin strength and elasticity and houses hair follicles and sweat glands, playing a vital role in thermoregulation and sensation.

The subcutaneous layer, also referred to as subcutis or hypodermis, consists primarily of fat and connective tissue. This layer helps insulate the body, absorb shock, and provide a reserve of energy, as well as anchoring the skin to underlying structures like muscles and bones.

The arrangement and function of these layers are essential for the skin's overall health and protective capabilities, illustrating why the selection of Epidermis, Dermis, and Subcutaneous accurately represents the three primary layers of human skin.
