The nail bed is the skin beneath the visible part of the nail, known as the nail plate. It is rich in blood vessels and nerves, which help to support nail growth and provide sensation. The nail bed plays a crucial role in the overall health of the nail, as it helps anchor the nail plate and protects the underlying tissues. The nail bed is part of the larger structure of the nail, which includes the nail matrix (where new nail cells are produced) and the cuticle (the skin at the base of the nail). Proper care of the nail bed is important for maintaining healthy nails and preventing infections.
