What is the matrix?

The matrix refers to the area beneath the base of the nail where new nail cells are generated. This area plays a crucial role in nail growth, as it is composed of living cells that multiply and harden as they reach the surface, forming the hard structure of the nail plate. Understanding the function of the matrix is essential for nail technicians, as it impacts the overall health and appearance of the nails.

Other options do not accurately describe the matrix. The area where nail polish is applied refers to the nail's surface rather than the matrix itself. The part of the nail that extends past the fingertip pertains to the free edge of the nail, and the skin that protects the surrounding nails refers to the cuticle and other skin surrounding the nail, neither of which is involved in the growth process that occurs in the matrix. This distinction highlights the importance of recognizing the specific anatomical features and functions of the nail for proper care and treatment.
