What are Fingernails Made of?

Aug 12, 2016

Chances are, you look at or use your fingernails on a daily basis. However, how much do you actually know about your nails? Below are some fun facts about the anatomy of your fingernails:

What Are My Nails Made of? 1

  • Nail plate – the top, visible portion
  • Nail bed – the skin featured below your nail
  • Cuticle – the tissue at the base of the nail that grows over the plate
  • Nail folds – the skin on each side of your nail and provides the frame
  • Lunula – the white, half-moon shape at the base of your nail
  • Matrix – the hidden portion of the nail just before and beneath the cuticle

How do Fingernails Grow? 1

Your nails grow from the matrix and are primarily comprised of a protein called Keratin — the same protein that contributes to the growth of your hair and skin. The growth rate of a fingernail typically varies, but averages 0.1mm each day, which is faster than the average growth rate of your toenails.
