Verified step by step guidance

Understand the concept of 'prime mover' in muscle actions: The prime mover is the muscle primarily responsible for producing a specific movement during an action.

Learn the definition of 'agonist': The agonist is the muscle that acts as the prime mover, contracting to create the desired movement.

Differentiate between related terms: Synergist muscles assist the agonist by stabilizing or enhancing the movement, fixators stabilize the origin of the agonist, and antagonists oppose the action of the agonist.

Recognize that 'agonist' is synonymous with 'prime mover' because it directly performs the movement.

Apply this understanding to the question: The term 'agonist' is the correct answer as it is another word for 'prime mover' in muscle actions.
