What are the folds of normal skin that surround the nail plate called?

The folds of normal skin that surround the nail plate are referred to as nail folds. These structures play a critical role in protecting the nail matrix and the underlying tissues from bacteria and other pathogens. In addition to their protective function, nail folds also contribute to the overall aesthetics of the nail by providing a smooth contour around the nail plate.

Nail grooves, in contrast, are the depressions on the sides of the nail that create the boundary between the nail plate and the skin, but they do not encircle the nail. Nail margins pertain to the edges or borders of the nail plate itself rather than the skin surrounding it. Sidewalls are often used to describe the skin at the sides of the nail but do not encompass the entire area surrounding the nail plate as effectively as nail folds do. Understanding the anatomy of the nail and its surrounding structures is essential for proper nail care and maintenance in advanced manicure practices.
