What is the anatomical term for the cuticle found at the base of the nail?

The anatomical term for the cuticle at the base of the nail is known as the eponychium. This structure is located at the junction of the nail plate and the surrounding skin, and it acts as a protective barrier. The eponychium helps to shield the area between the skin and the nail plate from pathogens, thus preventing infections and contributing to the overall health of the nail.

The other terms listed refer to different components related to the nail anatomy:

• The hyponychium is the area of skin under the free edge of the nail.

• The nail fold refers to the skin that surrounds the nail on its sides and base, which supports and protects the nail structure.

• The perionychium encompasses both the eponychium and the lateral nail folds, representing the area that includes both the cuticle and the surrounding skin.

Understanding these distinctions enhances the knowledge of nail anatomy and its related protective functions.
