E.Protects the nails from bacteria
The nail matrix is the area where your fingernails and toenails start to grow. The matrix creates new skin cells, which pushes out the old, dead skin cells to make your nails. As a result, injuries to the nail bed or disorders that affect the matrix can affect your nail growth.
