A normal nail grows forward from which part?

Nails grow forward from the matrix, which is the tissue located beneath the base of the nail. The matrix contains cells that divide and produce new nail cells, which push old cells forward, resulting in nail growth. This vital area is often referred to as the "root" of the nail; it is not visible since it's located beneath the skin at the base of the nail.

Understanding the role of the matrix in nail growth is essential. It is in the matrix where the thickness and health of the nail are determined. Any damage to the matrix can lead to permanent changes in the nail or hinder growth altogether, making its function crucial for proper nail development.

While the nail bed supports the nail and the free edge is the portion that extends beyond the fingertip, neither of these areas is responsible for the actual growth process. The cuticle serves as a protective barrier for the matrix and nail bed but is not involved in the growth of the nail itself. Thus, the matrix is the correct answer as it is where nail growth originates.
