What is the main function of the dermis?

• A. To protect underlying tissues from infection and dehydration
• B. To store fat
• C. To produce melanin
• D. To provide nutrients and house nerves, glands, and follicles

Answer: (D)

The dermis acts as the skin’s life-support and communication layer. It carries the blood supply that delivers oxygen and nutrients to the epidermis, helps remove waste, and supports temperature regulation. It houses nerve endings and receptors, giving you sensation of touch, pressure, temperature, and pain. It also contains hair follicles, sweat glands, and sebaceous glands, which are essential for moisture, cooling, and protective secretions. Collagen and elastin in this layer give the skin strength and flexibility. Because of all these roles, its main function is to provide nutrients to the skin and to house nerves, glands, and follicles. The other options describe functions more associated with the epidermis (barrier protection and melanin production) or the deeper hypodermis (fat storage).
