The nail matrix plays a crucial role in nail growth and development. It is the tissue located at the base of the nail, beneath the cuticle. The primary function of the nail matrix is to produce new nail cells. As these new cells are created, they push the older cells forward, causing the nail to grow outward. This process results in the hardening of the cells as they move away from the matrix and ultimately form the nail plate.

The other options refer to different aspects of nail anatomy and conditions. While one option discusses living tissue under the free edge of the nail, that refers to the nail bed rather than the matrix itself. Another option describes a condition related to nail structure rather than the function of the matrix, and the last option pertains to a fungal infection affecting nails, which does not relate to the matrix's role in growth. Understanding the specific function of the nail matrix is vital for comprehending overall nail health and growth processes.
