1. Nail Anatomy and Physiology
The nail unit consists of the nail plate, nail matrix, nail bed, and cuticle. The nail plate is the visible, hard part of the nail and is composed of keratinized cells. The nail matrix is located at the base of the nail and is responsible for producing the nail plate.
The nail bed is the soft tissue that lies beneath the nail plate and provides it with support. The cuticle is a thin layer of skin that covers the base of the nail and protects the nail matrix.
