                  EXPERIMENTS THAT GO 
                  WITH THE AXIOMS OF 
                   Advanced Biostructural Correction™ 
                  
                  Experiment 
                  to demonstrate muscles pulling vertebrae anterior (toward the 
                  front of the body: 
                  
                  1. 
                  The 
                  pulling of the Psoas muscles in the lumbar spine. Sit in a 
                  normal chair. Note the Psoas muscles attach from the inside of 
                  the thighs 
                  (on the 
                  femur) 
                  and on the lumbar vertebrae 
                  (sometimes 
                  on the pelvis too). 
                  Stand up normally and note the pull of those muscles on the 
                  spine which pulls the lumbar vertebrae anterior 
                  (forward). 
                  
                  2. 
                  The 
                  pulling of the diaphragm on spinal bones from the upper 
                  lumbars to the midthoracics (attachment 
                  varies a bit from person to person). 
                  Notice that the diaphragm attaches to the ribs in front and 
                  the spine in back. Feel the spinal bones as you breathe out, 
                  pinch your nose shut, close your mouth and try to breathe in. 
                  
                       
                  You will notice the diaphragm pulls the back toward the front 
                  of the rib cage. 
                  
                  3. 
                  
                  Muscles above that point pulling the rest of the vertebra 
                  forward if they are displaced backward. Standing upright: Put 
                  a hand on your forehead and flex your head or neck or both 
                  forward against resistance supplied by your hand. As you go 
                  through the range of motion you will notice the various 
                  vertebrae in your neck and upper thoracic spine being pulled 
                  forward toward each other as the neck and head get farther and 
                  farther out in front of the trunk of your body.
