Keratin - the same substance that makes up hair.Anatomically fingernails and toenails, which are made of a tough protein called keratin and are produced from living skin cells in the fingers and toes, are made up of many different parts: * The free edge is the part of the nail that extends past the finger, beyond the nail plate. There are no nerve endings in the nail - this is the growing part of the nail still under the skin at the nail's proximal end. * eponychium or cuticle, is the fold of skin at the proximal end of the nail. * paronychium is the fold of skin on the sides of the nail. * hyponychium is the attachment between the skin of the finger or toe and the distal end of the nail. * nail plate is the hard and translucent portion, composed of keratin. * nail bed is the adherent connective tissue that underlies the nail, often colloquially referred to as the "quick." * lunula is the crescent shaped whitish area of the nail bed (when visible) * nail fold a fold of hard skin overlapping the base and sides of a fingernail or toenail. In common usage the word nail usually refers to the nail plate only
Nail StructureThe 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 half-moon shaped portion at the base of the nail, is called the cuticle, the white part of the nail is the lunula Possible correction: According to Wikipedia, The half-moon shaped portion at the base of the nail is actually the lunula. The cuticle is the thickened layer of skin surrounding fingernails and toenails, more correctly called the eponychium.
