The portion of the nail plate that is not visible on the body surface under a hand magnifier is the nail root or matrix.
The nail root or matrix is located beneath the skin behind the visible part of the nail, known as the nail plate. It is responsible for producing new nail cells that form the nail plate, pushing it outward as it grows. This area is not visible to the naked eye or under a hand magnifier because it is situated beneath the skin at the base of the nail.
