The part of the nail where the nail plate rests on, also a continuation of the matrix A, Nail Bed C. Matrix B. Nail Walls D. Lunula
The Correct Answer and Explanation is:
The correct answer is B. Nail Bed.
The nail bed is the area of skin beneath the nail plate where it rests. It’s a continuation of the matrix, which is the tissue beneath the base of the nail that produces new cells. The matrix is responsible for the growth of the nail, and the cells it produces are pushed toward the tip of the finger, forming the nail plate. As the nail grows, it remains attached to the nail bed.
The nail bed is composed of layers of skin that help support the nail plate and provide the necessary nutrients and moisture to keep the nail healthy. It contains blood vessels that supply oxygen and nutrients to the growing nail. The bed is typically soft and flexible, allowing the nail plate to move slightly with finger and toe movements.
The lunula (D), which is the visible white crescent-shaped part at the base of the nail, is also part of the matrix, but it is not the part the nail plate rests on. It is the visible portion of the matrix and can give clues about health, but it is not the site of direct contact with the nail plate.
Nail walls (C) refer to the skin folds surrounding the sides of the nail, offering some protection, but they don’t provide the direct resting place for the nail plate.
The matrix (A) is the tissue under the base of the nail that generates the new cells that form the nail, but it’s not where the nail plate directly rests. Therefore, the nail bed is the correct answer as it is the continuation of the matrix and the part where the nail plate sits.
