Which carpal bone is located most laterally in the proximal row?

Explanation:
In the proximal row of carpal bones, orientation is from the thumb side (lateral) to the little finger side (medial). The bones go scaphoid, lunate, triquetrum, and pisiform from lateral to medial. The scaphoid sits closest to the radius on the thumb side, making it the most lateral bone in that row. Its position helps form the radiocarpal joint and it’s the bone you’d most readily identify on the lateral aspect of the wrist. The others are progressively more medial, with the pisiform sitting on the palmar surface and not at the lateral edge.
