Nails are essential anatomical structures found at the tips of fingers and toes in humans and many other animals. Composed of keratin, a tough protein, nails serve various purposes, including providing protection to the sensitive fingertips, aiding in gripping and manipulation, and acting as indicators of overall health. The nail structure consists of the nail plate, the visible part, and the nail bed underneath. The lunula, a crescent-shaped area near the base, is also noteworthy. Nails grow from the matrix, the tissue beneath the cuticle, and their growth is influenced by factors lik enetics, and nutrition.
