Arm & Shoulder Bones

The shoulder girdle is just two bones: the clavicle (collarbone) and the scapula (shoulder blade), which anchor the arm to the axial skeleton. The arm itself runs from the humerus in the upper arm down to the two forearm bones, the radius (thumb side) and the ulna (little finger side).
