Second, the force produced by the muscle must be large enough to overcome any opposing forces produced on the bone by other muscles or other forces (e.g., gravity or weight, ligaments, etc.). Our focus in this lab will be to understand the first condition – to examine a muscle and determine what kind of linear effects are produced by that muscle.
