What is the primary role of collagen in the skin?

• A. Absorbs UV radiation
• B. Provides strength and structure
• C. Regulates temperature
• D. Promotes hydration

Answer: (B)

Collagen plays a crucial role in providing strength and structure to the skin. It is a primary protein found in the dermis, which is the skin layer located beneath the epidermis. Collagen fibers create a supportive matrix that gives the skin its firmness and elasticity, enabling it to withstand stretching and maintain its shape. This structural support is essential for the overall integrity of the skin, contributing to its resilience against various forms of physical stress and degradation over time. As skin ages, collagen production decreases, leading to wrinkles and sagging, which highlights its importance in maintaining youthful and healthy skin. The other roles mentioned, such as absorbing UV radiation, regulating temperature, and promoting hydration, do not accurately reflect the primary function of collagen in the context of skin anatomy and physiology. While other components of the skin are responsible for those functions, collagen's main contribution is to enhance the strength and structural framework.
