What are the slits or furrows on each side of the nail called?

The slits or furrows on each side of the nail are referred to as nail grooves. These grooves are important anatomical features of the nail that help guide its growth and maintain the structure of the nail plate. They create a defined space between the nail and the surrounding tissues, which can help in preventing bacterial or fungal infections by protecting the nail matrix and promoting healthy nail growth.

In the context of nail anatomy, nail grooves provide a natural boundary for the nails, ensuring that they grow properly and remain aligned with the surrounding structures. This aids in the overall aesthetics and functionality of the nails. Understanding the role of nail grooves is crucial for anyone studying cosmetology, as it pertains to nail care, nail enhancements, and overall nail health.
