Which structure provides the underlying support for the nail plate and contains blood vessels?

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

Answer: (A)

The nail bed is the structure that provides underlying support for the nail plate and contains blood vessels. It sits directly under the nail plate and has capillaries that nourish the growing nail, helping it stay attached and healthy. The nail plate is the hard, protective layer that covers the bed, while the nail matrix is the growth zone located under the skin at the base that produces the plate, and the lunula is just the visible part of the matrix. So, the bed’s combination of support and blood supply makes it the best answer.
