Bontrager's Radiographic Positioning Practice Exam

The wrist’s carpal region is made up of eight small bones, organized into two rows. In the proximal row are the scaphoid, lunate, triquetrum, and pisiform. In the distal row are the trapezium, trapezoid, capitate, and hamate. This two-row arrangement accounts for the total number of carpal bones, with the pisiform often noted as a sesamoid within the flexor carpi ulnaris tendon but still counted among the carpal bones.
