The nail folds protect the nail matrix.What are the 5 stages of nail growth?
- Cells divide in the Matrix. …
- New cells are pushed forward by constant cell reproduction.
- Cells undergo hardening, this is also known as Keratinisation.

3.2. The nail plate sits on the nail bed.

The visible part of the matrix represented as white lunula is located at the base of the nail plate.
How is the nail plate formed?
All nail growth occurs at the nail’s base, where the specialized cells that make up the nail’s plate are produced; these cells are pushed forward as new cells form behind them. The nail plate is also attached to the underlying, richly vascularized nail bed, which supplies the plate with necessary nutrients.
What is the dorsal nail plate?
The Dorsal Nail Plate is a new device that links a specifically designed stem to a small distal plate; bone fixation is supported by fixed-angle screws.

Behind the cuticles on fingers and toes, just beneath the skin, a structure called the “root” churns out living cells that go on to form the nail.
