- 7. a basic contracting unit over each muscle fiber
- 9. chemical on motor neuron that initiates reactions
- 10. a nigh energy bond is split in this material to yield energy
- 13. chemical product of a broken high energy bond
- 14. nerve cells that stimulate a muscle fiber
- 17. after exercise one will breathe deeply to pay back what
- 20. skeletal muscles atrophy
- 23. stored in the muscles to provide a constant source of energy
- 25. involuntary contraction of muscles
- 26. a thin fibrous connective tissue that covers the fiber bundles
- 27. contractions that produce movement by the muscles shortening
- 29. name for a bundle of fibers

Down
- 1. what most of the energy released during muscle activity is used for
- 2. area between the Z bands and the functional unit of the contractile unit
- 3. muscles increase
- 4. a thin covering over each muscle fiber
- 5. type of exercise that does increase the heart rate
- 8. weakness, fatigue of voluntary muscles
- 11. inability to move muscles due to failure of nervous system
- 12. a flattened disc on the muscle fiber
- 15. violent, involuntary contraction of muscles, a sign of injury
- 16. contractions that are continual; helps maintain posture
- 18. sheath fibrous connective tissue that covers skeletal muscle
- 19. thick protein filament
- 21. type of exercise that does not increase the heart rate
- 22. strained muscles on front of lower leg
- 24. contractions that increase in tension without producing movement
- 28. continuous contraction of muscles; lockjaw
