Muscles

Prime Mover = responsible for movement i.e. Biceps brachii = forearm flexion

Antagonists = resists movement of prime moveri.e. Triceps brachii = forearm extension

Synergists = Aid prime movers i.e. Brachioradialis for forearm flexion

Muscles

1. Of the head and face

2. Of the pectoral girdle & arms

3. Of the thorax & abdomen

4. Of the pelvic girdle & legs
