The bones of the arm, wrist and hand labelled on the right include: the humerus (upper-arm bone and the following features on the humerus greater tubercle, head (of humerus), lateral epicondyle, medial epicondyle) the radius (lower-arm bone), the ulna (lower-arm bone), the 8 carpal bones scaphoid, trapezium; trapezoid, lunate, pisiform, triquetrum, hamate, capitate, the 5 metacarpal bones, and ; the 14 phalanges.
