What is the curved fold of the skin on the sides of the nail known as?

The correct identification of the structure on the sides of the nail as a nail groove is a key aspect of nail anatomy. The nail groove is defined as the curved fold of skin that runs alongside the nail. It plays a critical role in protecting the nail as it grows and helps secure the nail plate in place. This groove is influenced by factors such as overall health and nail care routines, making it an important feature to recognize for anyone studying for a manicure license or working in nail care.

Understanding the nail structure is essential for proper nail care and hygiene. While terms like nail mantle, hyponychium, and nail bed refer to different components or areas of the nail unit, the nail groove specifically refers to the skin that encircles the sides of the nail, ensuring that the nail is held firmly in position and is less susceptible to damage. Having a clear grasp of this terminology not only aids in effective manicure practices but also helps in educating clients about nail health.
