What are the furrows on the sides of the nail that guide growth referred to as?

The term used to describe the furrows on the sides of the nail that guide its growth is "nail grooves." These grooves play an important role in defining the shape and direction of nails as they grow. They facilitate the process of nail growth by creating a pathway that helps to ensure that the nail plates grow in a specific direction. Understanding the anatomy of the nail, including the function of nail grooves, is crucial for anyone pursuing a career in manicuring and nail care, as it informs techniques for proper nail maintenance and health.

Nail folds refer to the folds of skin that frame the sides of the nail. While they are closely related to nail growth, they do not specifically guide growth like nail grooves do. Nail slits are not a recognized term in this context, and nail ridges usually refer to vertical or horizontal lines on the nail surface rather than furrows that guide growth. Recognizing the correct terminology and anatomy can enhance both practice and communication in the salon environment.
