What does the sterile matrix refer to in nail anatomy?

The sterile matrix in nail anatomy refers specifically to the region that extends from the lunula to the hyponychium. This area plays a crucial role in nail growth and health, as it contains the cells responsible for producing the nail plate. The lunula is the visible part of the matrix at the base of the nail, while the hyponychium is the area beneath the nail tip. This entire region is involved in the formation and nourishment of the nail as it grows outward. Understanding the sterile matrix is important for comprehending how nails are formed and the potential impact of various conditions on nail health.
