What is the function of the dermis?

• A. Provides strength, elasticity, and nourishment to the skin.
• B. Produces melanin for skin color.
• C. Stores fat for insulation.
• D. Regulates sweat glands.

Answer: (A)

The dermis provides strength and elasticity to the skin and nourishes it. It’s packed with collagen and elastin fibers that give skin durability and flexibility, so it can bend without tearing. Its rich network of blood vessels brings oxygen and nutrients to the epidermis and helps keep the skin healthy. While other options point to processes in different layers (melanin production in the epidermis, fat storage in the subcutaneous layer), and while sweat glands reside in the dermis, the primary function described here is the combination of strength, flexibility, and nourishment that the dermis supplies.
