Which term describes the skin that overlaps the nail plate?

The term that describes the skin overlapping the nail plate is the perionychium. This anatomical structure is crucial in nail health as it serves to protect the area surrounding the nail and can be found where the skin meets the nail.

The perionychium is involved in maintaining the integrity of the nail unit and helps prevent infections by acting as a barrier to pathogens. Understanding the function and location of the perionychium is essential for anyone studying nails, as it is important for both health and beauty practices.

The other terms referenced do have specific meanings related to nail health, but they do not accurately describe the skin that overlaps the nail plate. For example, the nail matrix is the tissue beneath the nail that produces the nail plate, agnails refer to hangnails, and nail folds are the folds of skin at the sides of the nail. Each of these structures plays a role in nail formation and health, but the perionychium specifically describes the overlapping skin.
