| Fulcrum lies between the pull and the load b. Not abundant in the human body; serve as levers of stability | First-class levers a. |
| —a muscle that directly performs a specific movement | Prime mover |
| 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 | . Antagonist |
| . Fixator muscles | joint stabilizers |
| —muscles that contract at the same time as the prime movers; they facilitate prime mover actions to produce a more effi-cient movement | Synergists |
| —any “mover” muscle that directly performs a movement, including the prime mover | Agonist |
