Verified step by step guidance
1
Step 1: Begin by understanding the anatomical structure of the finger. The tip of the finger includes several components such as the nail plate, nail bed, distal phalanx, and lunula.
Step 2: Define each term provided in the options:
- Nail plate: The hard, keratinized structure that forms the visible part of the nail.
- Nail bed: The skin beneath the nail plate that supports it.
- Distal phalanx: The bone located at the tip of the finger.
- Lunula: The crescent-shaped whitish area at the base of the nail plate.
Step 3: Focus on the specific region mentioned in the question, which is the tip of the finger where the nail is located. This region includes both the nail plate and the underlying structures.
Step 4: Eliminate options that do not directly refer to the tip of the finger. For example, the lunula is part of the nail but is located at the base, not the tip. Similarly, the nail bed refers to the skin beneath the nail plate, not the tip itself.
Step 5: Identify the term that most accurately describes the anatomical region at the tip of the finger where the nail is located. Consider the relationship between the nail plate and the distal phalanx, as both are closely associated with this region.
