What is the function of the Eponychium?

To thicken the nail plate
To protect the matrix area
To allow nail growth
To darken the nail

The correct answer is: To protect the matrix area

The eponychium, also known as the cuticle, is the thin, protective layer of skin that covers the base of the nail. This helps prevent bacteria, fungi, and other harmful substances from entering the nail bed and causing infections. It also helps keep the matrix area, where new nail cells are formed, moist and protected. Options A, C, and D are incorrect because thickening the nail plate, allowing nail growth, and darkening the nail are not functions of the eponychium.
