Which structure is responsible for nail growth?

Explanation:
Nail growth comes from the nail matrix, the tissue beneath the proximal nail fold that generates the cells that become the nail plate. The matrix is where new keratin-producing cells are formed; as these cells multiply and harden, they are pushed outward to create the visible nail plate. The nail bed is the skin beneath the plate that supports and nourishes it, the nail plate is the hard, visible portion, and the cuticle protects the matrix at the base. If the matrix is damaged, growth can be affected, leading to ridges or irregular nails. So, the structure responsible for nail growth is the nail matrix.
