Which statement accurately describes the two main layers of the skin?

• A. The epidermis is the only main layer.
• B. The epidermis and dermis are the two main layers.
• C. The dermis is the outermost layer.
• D. The subcutaneous layer is the primary skin layer.

Answer: (B)

The skin has two main layers: the epidermis on the outside and the dermis beneath it. The epidermis acts as a protective shield, with cells that continually shed and are replaced, keeping the surface barrier intact. The dermis lies below the epidermis and provides strength and flexibility to the skin; it contains connective tissue, blood vessels, nerves, sweat and oil glands, and hair follicles, which support sensation, temperature regulation, and hair growth. Beneath the dermis is the subcutaneous layer (hypodermis), which is mainly fat and not considered one of the primary skin layers. This is why the statement describing the epidermis and dermis as the two main layers is accurate, while describing the dermis as the outermost layer or the subcutaneous layer as the primary skin layer isn’t correct.
