Solehorn: This type of cuticle is a layer of translucent, dead tissue that is shed from the seal between the nail plate and the hyponychium. As we age, the nail plate becomes thinner and we see evidence of the ‘rail and groove’ as vertical ridges in the nail plate. The epidermis moves forward with the nail plate and is attached to the dermis by tiny ‘rails and grooves’ that allow the nail plate to move - much like a train rides on its tracks. The dermis is the lower portion which is attached to the bone, while the epidermis lies just underneath the nail plate. Nail Bed: The nail bed is made of two types of tissue: dermis and epidermis. It is the shape of the fingertip bone that determines if the nail plate is flat, ski-jump, arched or hooked. The size, length and shape of the matrix determine width and thickness of the nail plate. Matrix: The matrix produces the cells that become the nail plate. Hair and skin are also keratin protein however, they are much softer and more flexible. These proteins are a strong, flexible material made from many layers of dead, flattened cells. Nail Plate: The nail plate is made of keratin protein formed by amino acids. As these cells grow forward, they lose their inner material and become flat, hard and transparent.ĭistal Edge: The distal edge is commonly referred to as the ‘free edge’. Lunula: The opaque pale white ‘half moon’ at the base of the nail, and forms the emerging immature, plump nail plate cells. It is this transparent skin, which is called the ‘true cuticle’, that is removed during the manicuring process. Lateral nail fold: Is an extension of the proximal nail fold and protects each side of the nail plate.Įponychium is the visible part of the proximal nail fold that appears to end at the base of the nail.Ĭuticle: The eponychium will shed a thin, colorless layer of skin that rides on the nail plate and appears to grow from under the proximal nail fold. Proximal nail fold: means ‘nearest attached end’ and is the soft tissue that protects the emerging nail plate. Our fascination with long nails continues to grow, and has established nails as a multi-billion dollar industry.Īsk someone to show you their fingernails, and they will usually point to the nail plate however, the plate is only one of the many parts that comprise the complete nail unit. Chinese men also grew long nails as a sign of their masculinity and to protect themselves from evil. To protect their nails, they often sheathed them in gold or silver. According to an article in Nailpro Magazine, the desire to have long beautiful nails first began during China’s Ming dynasty (1368-1644), when aristocratic women grew their nails up to 10 inches long as a sign that they performed no manual labor.
