What is the function of the cuticle in nail structure?

The cuticle plays a vital role in protecting the area between the nail plate and the living skin, which includes the matrix where new nail growth occurs. By forming a barrier, the cuticle helps to prevent potential infections and foreign substances from entering the delicate area beneath the nail bed. The integrity of this protective layer is crucial for maintaining nail health and ensuring that the underlying tissues remain safe and unharmed.

While other aspects of nail anatomy contribute to growth, support, and appearance, the specific function of the cuticle is its protective capacity, making it essential to nail care. It is important to maintain the cuticle properly to support overall nail health and growth indirectly, but its primary role is that of protection rather than direct involvement in color or structural support to the matrix.
