| Prime mover | a muscle that directly performs a specific movement |
| Agonist | any “mover” muscle that directly performs a movement, including the prime mover |
| Antagonist | muscles that, when contracting, directly oppose prime movers; relax while the prime mover (agonist) is contracting to produce movement; provide precision and control during contraction of prime movers |
| Synergists | muscles that contract at the same time as the prime movers; they facilitate prime mover actions to produce a more effi-cient movement |
| Fixator muscles | joint stabilizers (type of synergist) |
| Origin | point of attachment that does not move when the muscle contracts |
| Insertion | point of attachment that moves when the muscle contracts |
