What is the term for the cuticle that overlaps the base of the nail plate?

The term for the cuticle that overlaps the base of the nail plate is known as the eponychium. This is a critical structure in nail anatomy, as it serves several important functions. The eponychium acts as a protective barrier that helps prevent pathogens from entering the space between the nail bed and the nail plate, which can reduce the risk of infection.

In addition, the eponychium contributes to the overall health of the nail matrix, the area where new nail cells are generated. Proper care and maintenance of the eponychium are essential for promoting healthy nail growth and appearance. Recognizing and understanding anatomical terms like eponychium is important for professionals in cosmetology, as it equips them with knowledge relevant to nail care and health practices.

By contrast, terms such as lunula refer to the visible part of the nail matrix that appears white and crescent-shaped at the base of the nail, while the cuticle typically refers to the dead tissue that adheres to the nail plate. The nail fold, on the other hand, describes the skin surrounding the nail on either side, but does not specifically denote the overlapping cuticle at the base. Understanding these distinctions helps clarify the anatomy of the nail for better management and
