Across
- 2. muscle(s) which support the movement by contributing force and stabilizing
- 5. pulling force transmitted through an object with forces acting on opposite sides
- 6. consist of actin and myosin proteins and is the site of skeletal muscle contraction
- 8. muscle which opposes the action and relaxes when the agonist is contacted
- 9. thin contractile filaments
- 10. main muscle for movement
- 11. ability to cause rotation on a lever and depends on the amount of force, angle of force and momentum
- 13. bundles of muscle fibers
- 14. ability of muscle cells to forcefully shorten
- 16. muscle non-striated contracts involuntarily and is found lining internal organs
Down
- 1. ability of a muscle to be stretched
- 3. ability of a muscle to return to its original length when relaxed
- 4. muscle contract voluntarily and are attached to bones
- 6. thick contractile fragments
- 7. repeating units of actin and myosin and is the site of muscle contraction
- 12. ability for a muscle to respond to stimuli
- 15. Muscle striated, branched structures which contract involuntary and form the heart walls
