Know Your Nails
Your nails are made up of layers of Keratin-a protein thatís also found in your hair and skin. Each nail is comprised of several parts, including:
The structure we know of as the nail is divided into six specific parts- the root, nail bed, nail plate, eponychium (cuticle), perionychium, and hyponychium. Each of these structures has a specific function, and if disrupted can result in an abnormal appearing fingernail.
The root of the fingernail is also known as the germinal matrix. This portion of the nail is actually beneath the skin behind the fingernail and extends several millimeters into the finger itself. The fingernail root produces most of the volume of the nail and the nail bed. This portion of the nail does not have any melanocytes, or melanin producing.
The Nail plate is the actual fingernail, made of translucent keratin. The pink appearance of the nail comes from the blood vessels underneath the nail. The underneath surface of the nail plate has grooves along the length of the nail that help anchor it to the nail bed.
This is the skin that frames each of your nails on three sides
Your nail bed is the skin beneath the nail plate.
The Cuticle is situated between the skin of the finger and the nail plate fusing these structures together and providing a waterproof barrier. Your cuticle tissue overlaps your nail plate at the base of your nail.
