What is the primary function of the cuticle in nail anatomy?

The primary function of the cuticle in nail anatomy is to protect the matrix, which is the area of tissue beneath the base of the nail that is responsible for producing new cells. The cuticle acts as a barrier that seals the area between the skin and the nail plate, preventing pathogens, pollutants, and other harmful substances from entering and damaging the nail matrix. By serving this protective role, the cuticle helps maintain the health of the nail and supports its growth and integrity. Understanding this function is crucial for nail care and maintenance in manicure and pedicure practices, emphasizing the importance of keeping the cuticle healthy and intact to promote overall nail health.
