Verified step by step guidance

Step 1: Begin by identifying the key structures of the nail anatomy. The nail consists of several parts, including the nail bed, lunula, cuticle, and nail plate. Each structure has a specific function and role in nail health.

Step 2: Understand the function of the nail bed. The nail bed is the layer of skin beneath the nail plate. It contains many nerves and blood vessels, which are responsible for supplying nourishment to the nail and supporting its growth.

Step 3: Clarify the role of the lunula. The lunula is the whitish, crescent-shaped area at the base of the nail plate. It is part of the matrix but does not contain the blood vessels and nerves that supply nourishment.

Step 4: Examine the cuticle. The cuticle is the thin layer of skin at the base of the nail plate that protects the nail matrix from infection. It does not play a direct role in supplying nourishment to the nail.

Step 5: Review the nail plate. The nail plate is the hard, visible part of the nail made of keratin. It is not involved in supplying nourishment but serves as a protective covering for the nail bed.
