CAMRT Radiography Practice Exam

What are the carpal bones in the proximal row in order from medial to lateral?

1. Scaphoid, Lunate, Triquetrum, Pisiform

2. Pisiform, Triquetrum, Lunate, Scaphoid

3. Triquetrum, Pisiform, Scaphoid, Lunate

4. Lunate, Scaphoid, Pisiform, Triquetrum

The correct answer is: Pisiform, Triquetrum, Lunate, Scaphoid

The correct answer lists the carpal bones in the proximal row from medial to lateral accurately. When considering the anatomy of the wrist, the proximal row consists of the scaphoid, lunate, triquetrum, and pisiform bones. Starting from the medial side (the side closer to the body) of the proximal row, the triquetrum is indeed located adjacent to the lunate. Next, moving laterally, the scaphoid is in the most lateral position in the proximal row. The pisiform is a small bone sitting atop the triquetrum and does not directly align in the same row as the other three but is included in this examination of the proximal carpal bones. Thus, the order from medial to lateral is correctly represented by the choice: pisiform, triquetrum, lunate, and scaphoid. This highlights the importance of spatial orientation in understanding the wrist's anatomy, particularly for radiographic evaluation and procedures that require precise knowledge of anatomical landmarks.
