What is the part of the nail plate that extends over the tip of the finger or toe called?

The part of the nail plate that extends over the tip of the finger or toe is called the free edge. This area is the portion of the nail that is not attached to the nail bed and extends beyond the fingertip or toe, providing protection to the delicate tips of the fingers and toes. The free edge can vary in length and shape, depending on the individual and grooming habits. Understanding the anatomy of the nail is essential for professionals in cosmetology, as it helps in providing appropriate nail care and services.

The other components mentioned play different roles in the structure and functionality of the nail. The nail matrix is where new nail growth occurs, the nail bed supports the nail plate and provides a connection between the nail and skin, while the lunula is the visible part of the matrix at the base of the nail that appears as a whitish crescent shape. Each part serves a specific function, but it is the free edge that specifically refers to the part extending over the fingertip or toe.
