Nail plate lies on the nail bed. Matrix is the area where nail growth originates. It lies below the skin. Matrix has specialized cells which keep dividing and creating nail cells. The nail cells grow and produce a hard protein called keratin. Then, these keratin filled cells are pushed forward as more new cells are formed behind them. Eventually, the keratin filled cells die and flatten to form the nail plate. The hard keratin in these dead cells gives strength to the nail and makes it hard. Do you know what is the use of these nails? Nails protect our finger tips. Moreover, by observing the condition of our nails, doctors can get clues about our overall health.
