What is the deep pocket-like structure that holds the root and the matrix of the nail?

The deep pocket-like structure that holds the root and the matrix of the nail is known as the mantle. This is an essential component of the nail unit, providing both support and protection for the growth area of the nail. The mantle is where the nail matrix is located, which is the tissue responsible for nail growth.

The nail matrix produces new cells that eventually harden and form the nail plate as they move outward. The structure's design allows it to cradle and secure the nail root, making it vital for maintaining healthy nail development. Understanding the anatomy of the nail, including the role of the mantle, is crucial for anyone in the field of nail technology, as it relates to nail growth, health, and care practices.
