Chapter 1 -- Part 4
The interconnectedness of the musculoskeletal system is one of the aspects of the body dynamics.
A change in muscle tension or limb position in one part of the body must be accompanied by a change in other parts of the body.
The system can be seen as a tentlike structure.
The tent poles and the muscles are the things that bring the ropes into and balance the body.
The proper functioning of this type of structure requires that the forces be distributed over all the bones and muscles.
The tent collapses if the tension in the back ropes is not increased.
The same thing happens with the musculoskeletal system.
The large muscles at the front of our legs tend to pull the torso forward.
The muscles in the back have to tighten to compensate for the forward pull.
Excess tension in one set of muscles may be seen as pain in another part of the body.
The person's weight is distributed on both feet if they don't slide.
The relationships were stated.
The lower part of the arm is no longer horizontal.
