Which nail structure is responsible for nail growth?

The matrix is the part of the nail structure that is primarily responsible for nail growth. It is located beneath the base of the nail, under the cuticle area. Within the matrix, cells proliferate and harden, forming the new nail plate that pushes older cells forward. This continuous process of cell division and maturation is what allows the nails to grow over time.

Understanding the role of the matrix is crucial as it highlights the biological processes underlying nail growth. Proper care of the surrounding areas and the health of the matrix is essential for maintaining healthy nail development.
