At its base, where it attaches to the finger and cuticle, the normal human fingernail has a small, white half-moon shape. Although some people are born deaf to the half-moon, or lunula, shape on their nails, the lack of this design element on your nails might be a sign of a vitamin deficiency or another serious health problem.
Nails grow in a specific area under the skin called the matrix. Produce more cells by using the matrix. At that point, the cells start to aggregate and expel themselves from the skin. A lunula, a white half-moon at the base of a nail, could be an indication of many different kinds of disorders. The fifth basal elastin layer is obscured under the blood cells, giving the impression of a white nail in this location.
