It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger. Finally, the nail functions as a tool, enabling for instance a so-called "extended precision grip" (e.g.pulling out a splinter in one's finger), and certain cutting or scraping actions.As new nail plate cells are made, they push older nail plate cells forward; and in this way older cells become compressed, flat, and translucent.This makes the capillaries in the nail bed below visible, resulting in a pink color.It is not visible in some individuals while it is highly prominent on others.Together, the eponychium and the cuticle form a protective seal.The growing part of the nail is under the skin at the nail's proximal end under the epidermis, which is the only living part of a nail.In mammals, the growth rate of nails is related to the length of the terminal phalanges (outermost finger bones).
