What is the base part of the nail called?

The base part of the nail is referred to as the nail matrix. This is the area located beneath the base of the nail, which is where nail growth occurs. The nail matrix is made up of living cells that divide and push older cells out, creating the hard nail plate. This area is crucial as it determines the thickness, shape, and overall health of the nail. A healthy nail matrix contributes to the appearance and strength of the nails, making it a fundamental component in nail biology.

In contrast, the nail bed is the area underneath the nail plate that provides support and nourishment to the nail. The nail plate is the visible part of the nail, and the cuticle is the skin found at the base of the nail that protects the matrix from infection.
