What is a "nail"?
A nail is a protective structure composed of keratin located at the end of each finger and toe. It serves as a shield, covering the fingertip or toe, and acts as a barrier against potential damage and infection. Nails also contribute to tactile sensation and enhance sensitivity in the fingertips. They can grow and be trimmed, and their appearance can be influenced by various factors, including health and personal care habits. Understanding the anatomy and function of nails is important for maintaining nail health, hygiene, and overall hand and foot function.
