The nail bed is attached to the underlying bone by specialized:

• A. elastic fibers
• B. adipose tissue
• C. reticular fibers
• D. collagen fibers

Answer: (D)

Verified step by step guidance

1. Understand the anatomy of the nail bed: The nail bed is the skin beneath the nail plate, and it plays a crucial role in supporting the nail and providing nutrients for its growth.
2. Recognize the structural connection: The nail bed is firmly attached to the underlying bone to ensure stability and support for the nail plate.
3. Identify the type of connective tissue involved: Collagen fibers are a major component of connective tissue and are responsible for providing strength and structural integrity.
4. Eliminate incorrect options: Elastic fibers provide flexibility, adipose tissue stores fat, and reticular fibers form a supportive network in certain organs, but none of these are specialized for attaching the nail bed to the bone.
5. Conclude that collagen fibers are the correct answer: Collagen fibers are specialized for anchoring the nail bed to the underlying bone, ensuring a strong and stable connection.
