What does the term "matrix" refer to in relation to nails?

The term "matrix" in relation to nails refers specifically to the area at the base of the nail that is responsible for producing new nail cells. This part of the nail growth system is crucial because it generates the keratinous material that makes up the nail plate. As new cells are formed in the matrix, they push older, hardened cells forward, contributing to the growth of the nail. This continuous process allows the nail to grow longer while maintaining its structure. Understanding the role of the matrix is essential for anyone studying nail care and health, as issues in this area can directly affect nail appearance and growth.
