Which part of the nail receives no nutrients or blood?

• A. Nail bed
• B. Nail plate
• C. Cuticle
• D. Lunula

Answer: (B)

The nail plate is the part of the nail that does not receive any nutrients or blood. It is the hard, visible part of the nail that is made up of keratin, a tough protein. The nail plate acts as a protective barrier for the underlying structures, including the nail bed and the matrix, where the nail's growth begins. Nutrients and blood supply reach the nail primarily through the nail bed and matrix. The nail bed is the skin underneath the nail plate that contains blood vessels and nerves, which is essential for the health of the nail. The cuticle, while protective, primarily serves to seal the area between the nail plate and the skin, and the lunula is the visible part of the nail matrix. In contrast, the nail plate itself is not living tissue and therefore does not require its own supply of blood or nutrients. This distinct characteristic highlights the nail plate's role as a protective covering rather than a living structure.
