Assessments Complete the following statements: 1. The origin of a muscle is usually attached to a fixed location. 2. The insertion of a muscle is usually attached to a movable location. 3. A muscle responsible for most of a movement is called a prime mover. 4. Assisting muscles are called synergists. 5. Antagonists are muscles that resist the actions of prime movers and cause movement in the opposite direction. 6. When the forearm is extended at the elbow joint, the triceps muscle acts as the prime mover. 7. When the biceps brachii acts as the prime mover, the brachialis muscle assists as a synergist.
