Definition

Nail (Anatomy)
In anatomy, a nail is defined as a horn-like envelope covering the tips of the fingers and toes in humans, most non-human primates, and a few other mammals. Fingernails and toenails are made of a tough protective protein called alpha-keratin, a polymer. Alpha-keratin is found in the hooves, claws, and horns of vertebrates. The nail functions by protecting the digits and contributing to tactile sensation.
