Across
  1. 2. Calcium binds to this molecule that makes the tropomyosin expose the active site
  2. 4. Repeating unit of a skeletal muscle fiber
  3. 6. The SR functions to store____ions
  4. 7. Think filaments are connected to this central portion of the band
  5. 9. Is the length of the thick filaments
  6. 13. Steady increase in muscle tension by increasing the number of active motor units
  7. 15. Endurance that uses mitochondria to slowly burn oxygen and glucose to make ATP and CO2, not muscle building
  8. 16. Thick filaments are made of this
  9. 17. Muscle action potential is carried inside the muscle cell by___
  10. 19. Muscle fiber the has high fatigue resistance
  11. 20. Surrounds a group of muscle fibers
  12. 23. Each___is made of roughly 10,000 sarcomeres
Down
  1. 1. Muscle exceeds the load and the muscle shortens
  2. 3. Thin filaments are made of this
  3. 5. Peak tension is developed and the muscle elongates
  4. 8. Surrounds the skeletal muscle fibers
  5. 9. Z lines are made of this
  6. 10. Muscle that is not striated, have 1 nucleus
  7. 11. Surrounds an entire skeletal muscle
  8. 12. In___tetanus, muscle is stimulated to almost peak tension
  9. 14. Muscle fiber that can be found in the eye
  10. 15. Endurance that is a short burst, ATP and glycogen is stored, muscle building
  11. 18. In___tetanus, muscle is stimulated and increased to max tension
  12. 21. Contraction when tension is produced but never exceeds load and muscle length does not change
  13. 22. Muscle that is striated, mutli-nucleate, and elongated
