Fingernails

Fingernails have the function of protecting the the fingertip, and the surrounding soft tissues from injuries.  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).
