What is the name of the fold of skin on either side of the nail groove?

The fold of skin on either side of the nail groove is known as the nail wall. This structure helps protect the nail bed and contributes to the overall health and integrity of the nail. The nail wall surrounds the nail plate, providing support and enhancing the aesthetic appearance of the nail.

Understanding the anatomical features of the nail is crucial in nail technology, as proper care and attention to these areas can promote healthier nails and prevent issues such as hangnails or infections. The nail wall is distinct from the nail bed, which is the area under the nail plate, and the nail groove, which is the indentation that allows the nail to grow. The nail matrix, on the other hand, is the tissue located under the base of the nail that is responsible for producing the cells that make up the nail plate. Each of these structures plays a unique role in nail health and growth, but the nail wall specifically refers to the protective skin folds flanking the nail groove.
