What is an example of a synergist muscle?

During forearm flexion, for example lifting a cup, a muscle called the biceps brachii is the prime mover. Because it can be assisted by the brachialis, the brachialis is called a synergist in this action (Figure 11.1. 1). A synergist can also be a fixator that stabilizes the muscle’s origin.
