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

The part of the nail plate that extends over the tip of the finger or toe is known as the free edge. This is the portion of the nail that is not attached to the nail bed and extends beyond the fingertip, providing protection to the delicate tissues of the fingertip underneath.

The free edge is generally composed of hardened keratin and is the part that you can trim or shape during a manicure. Its primary function is protective, but it also contributes to the overall aesthetic appearance of the nail. Understanding this concept is important for maintaining healthy nails and performing nail care properly.

In contrast, the nail bed is the skin beneath the nail plate, the lunula is the visible part of the nail matrix at the base of the nail, and the matrix is the tissue under the base of the nail where new nail cells are produced. Each of these parts plays a different role in nail health and growth, but the correct answer specifically relates to the part of the nail that extends beyond the fingertip.
