What is the purpose of the lunula in nail anatomy?

The lunula, which is the visible part of the matrix located at the base of the nail, plays a significant role in nail growth. As the growth matrix, it produces new nail cells that push older cells forward, forming the hard nail plate. This area is essential for the formation and maintenance of healthy nails because it is where the nail originates. The lunula's visibility can sometimes provide insights into nail health, but its primary function remains the production of new cells contributing to nail length and strength. Understanding the role of the lunula is crucial for nail technicians, as it directly relates to their work in maintaining nail health and beauty.
