Where is the nail bed located relative to the nail body?

• A. The nail bed is located in the deeper layer of the dermis and covered by the nail body
• B. The nail bed is in the epidermis
• C. The nail bed is superficial to the nail body
• D. The nail bed is in the subcutaneous tissue

Answer: (A)

Think about where the nail plate sits in relation to the skin beneath it. The nail bed is the skin that lies under the nail plate, and it sits in the deeper (dermal) layers of the skin, with the nail body covering it from above. The nail plate grows from the nail matrix at the base and slides over this bed, so the bed remains beneath and supports the nail as it extends outward. That’s why the best description is that the nail bed is located in the deeper layer of the dermis and is covered by the nail body. The other possibilities place the bed in the epidermis, in subcutaneous tissue, or above the nail plate, which wouldn’t match the actual arrangement of nail anatomy.
