Which term describes body parts that are close to the point of reference?

• A. Proximal
• B. Distal
• C. Superior
• D. Inferior

Answer: (A)

Proximal describes body parts that are nearer to the point where a limb attaches to the trunk (the reference point). It helps to think of the limb as a ladder from the body’s core: parts closer to that attachment are proximal, while parts farther away are distal. For example, the elbow is proximal to the wrist because the elbow is closer to where the arm attaches to the shoulder than the wrist is. The thigh is proximal to the knee, and the shoulder is proximal to the elbow. In contrast, distal would describe parts farther from the attachment point, and superior/inferior describe vertical positions. So the term that fits “close to the reference point” is proximal.
