What is the significance of the keratin composition in nails?

• A. It helps in communication
• B. It prevents nail splitting
• C. It provides strength and durability
• D. It enhances nail color

Answer: (C)

The keratin composition in nails is crucial because keratin is a fibrous protein that provides nails with their structure and integrity. This robust protein contributes to the overall strength and durability of the nails, allowing them to withstand daily wear and tear. The unique arrangement of keratin fibers within the nail plate creates a tough and resilient surface that protects the underlying tissues and supports nail growth.

While other aspects of nails, such as their appearance or potential for damage, are influenced by various factors, the primary role of keratin is to ensure that nails remain sturdy and functional, ultimately serving their protective purpose effectively.
