Which description matches Epidermis?

• A. Middle skin layer with blood vessels and nerves
• B. Fat layer beneath skin
• C. Outer skin layer
• D. Flexible connective tissue

Answer: (C)

The epidermis is the outermost protective layer of the skin. It forms the surface you see and touch, and it sits atop the dermis. Unlike the deeper layers, the epidermis has no blood vessels of its own, so nutrients diffuse upward from the dermis below to keep it nourished. The middle layer, which has blood vessels and nerves, is the dermis and provides support and sensation. The fat layer beneath, the hypodermis, stores energy and adds insulation. Because of that, the description that best matches the epidermis is the outer skin layer.
