Which term describes near to a reference point?

• A. Proximal
• B. Distal
• C. Superficial
• D. Deep

Answer: (A)

Proximal is used to describe closeness to the point of attachment or to the trunk of the body. It means nearer to the reference point. In limbs, something proximal is closer to the body's center, while distal is farther away from that center. For example, the elbow is proximal to the wrist because the elbow is closer to the shoulder-trunk axis than the wrist is. The shoulder is proximal to the elbow. Superficial and deep talk about depth relative to the body surface: superficial is near the surface, deep is farther inside. So when the question asks for “near to a reference point,” proximal fits best because it specifically indicates nearness to that reference point.
