  3. 6. This muscle is often found in the walls of digestive organs and glands.
  4. 9. Involved in calcium induced calcium release.
  5. 10. Strategy of force regulation, increase frequency of AP.
  6. 12. ___ would decrease the activity of myosin light chain kinase.
  7. 13. Important ion involved in excitation-contraction coupling.
  8. 15. These molecules form a filament and also contain a binding site for the myosin heads.
  9. 16. Visual representation of layered thick and thin filaments.
  10. 19. Protein that sequesters calcium in SR.
  11. 20. Chemical signals used between neurons or neurons and muscle.
  12. 22. Important site for calcium storage.
  13. 23. Activity of this protein allows crossbridging in smooth muscle.

Down
  1. 1. Chief neurotransmitter released by motor neurons.
  2. 2. This muscle maintains striations, while also possessing intercalated disks.
  3. 4. Junction which separates motor neurons from skeletal muscle.
  4. 7. Important site for calcium storage.
  5. 8. Activating PKA causes this protein to increase the SR calcium pump in cardiac muscle.
  6. 11. Intrinsic property of the heart to beat on its own.
  7. 14. Calcium binds this protein. Exposing the actin-myosin binding site.
  8. 17. Source of electrical stimulation for the heart.
  9. 18. This muscle responds to calcium solely from intracellular stores.
  10. 21. Structure found at intercalated disks. Grants mechanical strength.
  11. 24. Strategy of force regulation, activate more motor neurons.
  12. 26. Extension of plasma membrane into myofibril.
