Synergist
From Wikipedia, the free encyclopedia
Synergist is a kind of muscle which perform, or assist in performing, the same set of joint motion as the agonists. Synergists are muscles that act on movable joints . Synergists are sometimes referred to as "neutralizers" because they help cancel out, or neutralize, extra motion from the agonists to make sure that the force generated works within the desired plane of motion.
