Upper Extremity - The arms are ultimately attached to the Upper Extremity - The arms are ultimately attached to the thorax, via synovial joints, at the collarbone and shoulder thorax, via synovial joints, at the collarbone and shoulder bone. The scapula is attached to the thoracic cage only by bone. The scapula is attached to the thoracic cage only by muscles. The elbow joint unites the humerus with the two muscles. The elbow joint unites the humerus with the two lower arm bones the ulna and radius. Three sets of joints lower arm bones the ulna and radius. Three sets of joints connect the radius and ulna to the bones of the palm, through connect the radius and ulna to the bones of the palm, through the eight small wrist carpals. Further, the knuckles connect the the eight small wrist carpals. Further, the knuckles connect the metacarpals to the proximal phalanx of the fingers. Each finger metacarpals to the proximal phalanx of the fingers. Each finger has 3 phalanges, cept the thumb which has only two. has 3 phalanges, cept the thumb which has only two.

Lower Extremity - The pelvis transmits the upper body weight Lower Extremity - The pelvis transmits the upper body weight from the sacrum to the legs. It begins as 3 hip bones which fuse from the sacrum to the legs. It begins as 3 hip bones which fuse together when growth is completed. The hip joint unites the together when growth is completed. The hip joint unites the pelvis to the thigh bone, he knee joint, which includes the knee pelvis to the thigh bone, he knee joint, which includes the knee cap (patella), links the femur to the lower leg bones the tibia cap (patella), links the femur to the lower leg bones the tibia and fibula.
