What is the visible part of the nail matrix called?

The visible part of the nail matrix is called the lunula. The lunula is the small, crescent-shaped area at the base of the nail, which is often visible and can vary in size and visibility from person to person. It is part of the nail matrix, the tissue under the nail, that produces the cells that become the nail plate. The presence of the lunula indicates that the nail is growing from that area; it is a vital part of nail anatomy. Being able to identify the lunula is important for nail technicians, as it can provide insights into the health of the nail and any potential issues with nail growth or formation.

The cuticle, eponychium, and hyponychium are important components of nail anatomy but serve different purposes and are not the visible part of the nail matrix. The cuticle is the layer of clear skin located along the bottom edge of the nail that protects the matrix. The eponychium refers to the skin that overlaps the base of the nail. The hyponychium is the area of the skin beneath the free edge of the nail. Understanding these distinctions helps nail technicians care for and maintain the health of their clients' nails effectively.
