Question asks you to name the bone or markings indicated by the letters for three prompts. Prompt 1: Identify which option corresponds to the marking labeled as A/B/C (the first prompt).

This structure is a distal projection of the ulna where the ulnar nerve and ulnar collateral ligaments connect, and it is a common anatomical landmark on the medial side of the forearm near the wrist. Why other choices are not correct for Prompt 1: Radial styloid process would be on the radius side (thumb side) of the wrist, not matching the ulna’s distal projection. Interosseous membrane is a fibrous sheet between the......Login to view full explanation
