Question

Quizplus · Accepted Answer

The prime mover in muscle action is also called the agonist. This is because it is the muscle responsible for producing the desired movement, and it contracts to cause that movement. Synergists are muscles that assist the prime mover by adding extra force or helping to stabilize the joint. Antagonists are muscles that oppose the prime mover, and they typically relax as the prime mover contracts. Fixators are muscles that stabilize the origin of the prime mover so that it can work more efficiently. Insertion refers to the attachment point of a muscle on the bone that it moves.
