Across
  1. 2. structural protein that anchors actin
  2. 4. branched and involuntary type of striated muscle
  3. 7. carries AP inside muscle fiber to the myofibrils
  4. 8. fixation of the cross bridge cycle due to lack of ATP
  5. 13. a common cholinesterase inhibitor
  6. 14. backbone of actin filament that binds myosin
  7. 15. composed of skeletal and cardiac muscle
  8. 17. forms pores into knob that allows Ca to flood in
  9. 18. autoimmune attack on nicotinic ACh receptors causing muscle weakness
  10. 23. a filamentous protein
  11. 24. binds to nicotinic ACh receptors blocking ACh and causing paralysis
Down
  1. 1. adding more motor units until desired contraction is reached
  2. 3. net like structure that releases Ca in skeletal muscle needed for contration
  3. 5. Voltage sensitive proteins in T-tubules that mechanically open Ca channels
  4. 6. motor neuron and all of the fibers that it innervates
  5. 7. controls binding of myosin via Ca
  6. 9. holds myosin in register
  7. 10. blocks docking or fusion of ACh vesicles causing paralysis
  8. 11. where actin and myosin overlap
  9. 12. middle part of myosin that doesnt overlap with actin
  10. 16. a protein in the SR that binds 43 Ca moderately
  11. 19. end parts of actin where it doesnt overlap with myosin
  12. 20. mediate the release of Ca in SR
  13. 21. the type of striated muscle that is voluntary
  14. 22. contractile unit that spans from z line to z line
