The broadest muscle of the back. It arises from the spines of the six lower thoracic vertebrae and from the FASCIA attached to the lumbar vertebrae and back of the pelvis and sweeps up and forward to be inserted by a short, broad tendon into the back of the top of the upper arm bone (humerus). It acts to pull the body upward in climbing and assists in heavy breathing.
