Explanation:

1. Recall anatomical directional terms:

• Distal means farther from the point of attachment (or trunk) of the body.
• Proximal means closer to the point of attachment (or trunk).
• Medial means toward the midline of the body.
• Lateral means away from the midline.

1. Identify the regions:

• The brachial region is the upper arm (near the shoulder/trunk attachment of the arm).
• The carpal region is the wrist (farther from the trunk along the arm).

1. Analyze the options:

• Option A: Carpal (wrist) is distal to brachial (upper arm) because it is farther from the trunk. This matches the definitions.
• Option B: Medial refers to midline, but carpal and brachial are along the arm's length, not midline/lateral in that axis. Eliminate.
• Option C: Proximal would mean closer to trunk, but wrist is farther than upper arm from trunk. Eliminate.
• Option D: Lateral refers to side - to - side, not along the arm's length. Eliminate.

Answer:

A. The carpal region is distal to the brachial region.
