Do you ever wonder what are those crescent-shaped whitish area found inside your nails? Not many people know what it is or what it does. Let's find out.
The lunula is the crescent-shaped whitish area of the bed of a fingernail or toenail. The lunula is the visible part of the root of the nail.
It is located at the end of the nail, but it still lies under the nail. It is not actually white but only appears so when it is seen through the nail. Outlining the nail matrix, the lunula is a very delicate part of the nail structure.
If one damages the lunula, the nail will be permanently deformed. Even when the totality of the nail is removed, the lunula remains in place and is similar in appearance to another smaller fingernail embedded in the nail bed.

In most cases, it is half-moon-shaped and has unique histologic features. Examinations concluded that the lunula was an area of loose dermis with lesser developed collagen bundles. It appears whitish because a thickened underlying stratum basale obscures the underlying blood vessels.
The lunula is most noticeable on the thumb; however, not everyone's lunula is visible. In some cases, the eponychium may partially or completely cover the lunula.
