Which statement about the skin's main layers is true?

• A. Stratum corneum, Dermis, and Subcutaneous tissue.
• B. Epidermis, Dermis, and Hypodermis.
• C. Epidermis, Hypodermis, and Muscle.
• D. Dermis, Hypodermis, and Hair follicles.

Answer: (B)

The skin has three main layers: the epidermis on the outside, the dermis in the middle, and the hypodermis (subcutaneous tissue) beneath. The epidermis provides the protective barrier, while the dermis contains connective tissue, blood vessels, nerves, glands, and hair follicles. The hypodermis is mainly fat and connective tissue that cushions and anchors the skin to underlying structures. The stratum corneum is part of the epidermis, not a separate main layer, so listing it with dermis and subcutaneous tissue leaves out the broader outer layer. Muscle isn’t a skin layer, and hair follicles are structures within the skin, not one of the main layers. Therefore, the statement naming the epidermis, dermis, and hypodermis correctly reflects the skin’s three primary layers.
