What is the term for the growth plate of a nail?

The growth plate of a nail is referred to as the matrix. This area, located underneath the base of the nail, is responsible for producing new nail cells. As these cells multiply and grow, they push older cells forward, leading to the development of the visible nail plate. The matrix is essential for nail health and growth, and any damage to this area can impair the growth of the nail or lead to abnormalities.

In contrast, the lunula is the visible part of the matrix and appears as a whitish crescent at the base of the nail. The free edge is the part of the nail that extends beyond the fingertip and does not contribute to nail growth. The nail bed is the skin beneath the nail plate, providing support but not participating directly in the growth process itself. Understanding the roles of these components is crucial for grasping nail anatomy and the growth process.
