Which part of the nail contains lymph, blood vessels and nerves that create cells?

• A. Matrix
• B. Nail bed
• C. Lunula
• D. Free edge

Answer: (A)

The matrix is where nail growth happens. It lies under the proximal nail fold and is rich in blood vessels, lymphatic vessels, and nerves, providing the nutrients and sensation needed for new nail cells. The cells here actively divide and keratinize to form the nail plate, which then grows outward over the nail bed. The visible lunula is simply the portion of the matrix that shows through at the base of the nail. The nail bed provides support and nourishment to the growing nail but does not generate the nail itself, and the free edge is the distal tip of the nail plate, not the growth region. So the matrix is the site that creates the cells that become the nail.
