What is the term for the cuticle that covers the base of the nail?

• A. Eponychium
• B. Hyponychium
• C. Matrix
• D. Lunula

Answer: (A)

The term for the cuticle that covers the base of the nail is called the eponychium. This structure serves an important protective function by covering the area where new nail growth occurs, which is at the nail matrix. The eponychium helps to prevent bacteria and other pathogens from entering beneath the skin and into the nail bed, maintaining nail health and integrity. In contrast, the hyponychium refers to the skin located beneath the free edge of the nail, serving as a barrier to protect the nail bed. The matrix is the tissue under the base of the nail responsible for producing new nail cells, and the lunula is the visible part of the matrix that appears as a white crescent moon shape at the base of the nail. Understanding these terms and their functions is crucial in nail care and maintenance as they relate to nail health.
