2. Proximal Row

"Proximal” describes a body part that is closest to the center of the body. In the case of the carpal bones, the proximal row is the one closest to the wrist. The scaphoid has a boat-like shape and is the largest carpal bone in the proximal row. The lunate is a moon-shaped bone that is the most commonly dislocated carpal bone. Together, the scaphoid and the lunate create half of the wrist joint, with the other half being the ulna and radius bones of the arm. The final two carpal bones on the proximal row are the triquetrum and the pisiform. The triquetrum has a pyramidal shape while the pisiform is small and round.
