Where does the nail plate grow from?

The nail plate grows from the nail root, which is situated beneath the cuticle area at the base of the nail. The nail root contains the actively dividing cells that produce the hard keratin structure of the nail. As these cells proliferate, they push the older, hardened cells forward, allowing the nail plate to gradually extend and grow outwards over the nail bed. This process is essential for nail health and growth.

The other options relate to different aspects of nail anatomy. The nail edge refers to the free tip of the nail that extends beyond the finger. The nail bed is the skin beneath the nail plate where the nail rests. The nail fold is the fold of skin that surrounds and protects the nail on either side. Understanding the function of each part of the nail provides a clearer picture of nail growth and health.
