Wound, Ostomy and Continence Nurses Society (WOCN) Practice Exam

Which layer is continuous with the cuticle?

1. Nail matrix

2. Proximal nail fold

3. Nail bed

4. Paronychium

The correct answer is: Proximal nail fold

The proximal nail fold is the correct answer because it serves as the area from which the cuticle originates. This semi-transparent layer of skin folds over the base of the nail and extends onto the nail plate. The cuticle acts as a protective barrier against pathogens and helps to maintain the health of the nail matrix beneath it. In anatomy, understanding the relationship between the proximal nail fold and the cuticle highlights their continuous nature. This connection is crucial for nail health and growth, as any disruption in this area can affect the nail's integrity. In contrast, the nail matrix is the structure responsible for nail growth but does not extend onto the nail plate itself. The nail bed is the underlying skin that supports the nail and is distinct from the cuticle. Paronychium refers to the tissue at the sides of the nail, which is adjacent to but separate from the proximal nail fold.
