| synovial joint are | freely moveable |
| synovial joints | shoulder, hip, knee, ankle |
| opposing bony surfaces | articular cartilage |
| fibrous joint capsule | surrounds synovial joints |
| joint movement limited by | bony architecture, ligaments, muscle orientation |
| ligaments | bone to bone |
| tendon | muscle to bone |
| kneecap | sesamoid bone |
| muscle action | mostly at joints |
| protagonist | antagonist |
| mover muscles | protagonist |
| assistant muscle mover | synergist |
| contraction | relaxation |
| neutralizers | muscle which helps to resist contracture |
| fixator | holds a muscle in place |
| muscle compartments | deep fascia |
| divided into smaller muscle bundles | fascicles |
| located in larger sheets of deep fascia | arteries, veins, and nerves |
| periosteum | connective tissue covering bone |
| severed nerve supply to muscles | muscle atrophy occurs |
