Fingernail Diagram Handout

Print out the handout below to learn about the different parts of your fingernail.

Nails function both to protect the sensitive tips of your fingers and as tools. Just like your hair, nails are made of a specially hardened protein called keratin. Nails are generally known to grow about 1cm in 100 days, but this rate can depend on many factors such as age, sex, and health.
