Which structure forms a pocket that holds the root and matrix?

• A. Mantle
• B. Lunula
• C. Nail Bed
• D. Cuticle

Answer: (A)

The mantle forms the pocket around the root and matrix. It surrounds the base of the nail where the root and matrix sit, creating the protective pocket that houses them as they function to produce the nail plate. The other structures have different roles: the lunula is simply the visible part of the matrix, the nail bed is the skin beneath the nail plate, and the cuticle protects the matrix but does not create the pocket itself.
