I Should Not Bite My Nails!
Have you ever thought about your nails and the job they do? The hard surface of your nails helps to protect your fingers and your toes -- plus, your fingernails make it easy to scratch an itch or pick something up. You had fingernails and toenails before you were even born!
Where do nails come from? Nails start in the nail root that’s hidden under the cuticle. When the cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden. The newly formed nail then slides along the nail bed, (the flat surface under your nails). The nail bed sits on top of tiny blood vessels that feed it and give your nails their pink color. They also grow slowly - about one tenth of an inch each month, so it takes about three to six months to completely replace a nail!
