35
breastbone
sternum
36
includes the 126 bones that form the pectoral girdle (the shoulders), the pelvic girdle (the hips), and the appendages (the arms and legs)
appendicular skeleton
37
the bone on the same side as your thumb, is attached to the ulna and humerus by a weaker but more movable joint that allows it to rotate around the ulna
