Verified step by step guidance

Step 1: Understand the terminology used in muscle movement. Muscles work in groups to produce movement, and each muscle has a specific role. The key terms to know are agonist (prime mover), antagonist, synergist, and fixator.

Step 2: Define the term 'agonist' (prime mover). The agonist is the muscle that provides the major force for producing a specific movement. It is the primary muscle responsible for the action.

Step 3: Define the term 'antagonist.' The antagonist is the muscle that opposes the action of the agonist. It relaxes while the agonist contracts to allow smooth movement.

Step 4: Define the term 'synergist.' Synergists are muscles that assist the agonist by adding extra force or reducing unnecessary movement during the action.

Step 5: Define the term 'fixator.' Fixators are muscles that stabilize the origin of the agonist, ensuring that the movement is efficient and precise.
