Muscles Prime Mover = responsible for movement i.e. Biceps brachii = forearm flexion Antagonists = resists movement of prime mover i.e. Triceps brachii = forearm extension Synergists = Aid prime movers i.e. Brachioradialis for forearm flexion

Muscles Of the head and face 2. Of the pectoral girdle & arms 3. Of the thorax & abdomen 4. Of the pelvic girdle & legs
