What is the name of the skin that overlaps the nail plate at the base?

• A. The cuticle
• B. The nail matrix
• C. The nail fold
• D. The lunula

Answer: (A)

The skin that overlaps the nail plate at the base is referred to as the cuticle. The cuticle is a protective barrier that helps prevent the entry of pathogens and bacteria into the nail matrix, where new nail cells are produced. This layer plays a crucial role in maintaining nail health by protecting the vulnerable area beneath it, ensuring that the nail grows properly without interruption from external factors.

In contrast, the nail matrix is the tissue beneath the base of the nail where growth occurs, while the nail fold refers to the skin surrounding the nail on the sides. The lunula, the visible part of the matrix at the base of the nail, is sometimes confused with the cuticle but is actually a different structure. Understanding these distinctions highlights the importance of the cuticle in nail anatomy and health.
