Across
  1. 2. (2 words) type of skeletal muscle which has a much faster contraction and relies on glycolysis for ATP
  2. 4. (2 words) structure of introversion of plasma membrane into the sarcomere
  3. 5. (2 words) metabolite which will provide phosphate for ATP synthesis
  4. 7. type of fatigue that occurs when the central nervous system is unable to activate motor neurons
  5. 12. (2 words) type of skeletal muscle which has a fast contraction and relies on oxidative phosphorylation for ATP
  6. 15. (2 words) type of skeletal muscle which has a slow contraction and relies on oxidative phosphorylation for ATP
  7. 16. type of fatigue that occurs when the neuromuscular junction fails to synthesize acetylcholine to maintain action potentials in the muscle cell
  8. 17. cylindrical contractile element made of sarcomeres in muscle
  9. 19. one of 3 proteins which compose the thin filaments in sarcomeres (threadlike and filamentous proteins follow the indentations of the actin chains)
  10. 21. type of muscle that is unstriated and involuntary
  11. 22. (2 words) name given to a motor neuron plus the muscle fibers that it stimulates
  12. 23. type of muscle that is striated and involuntary
  13. 24. maximal strength and smooth contraction due to rapid stimulation of muscle fiber
  14. 26. the name for the smallest unit of muscle that can perform a contraction
  15. 27. (2 words) alternate name for foot proteins
Down
  1. 1. protein which composes the thick filaments in sarcomeres
  2. 3. (2 words) tension increase due to frequent stimulation of muscle fiber
  3. 6. (2 words) structure within sarcomere which transports and stores calcium ions
  4. 8. type of muscle that is striated and voluntary
  5. 9. name of receptor protein in the transverse tubule which dictate permeability of foot proteins to calcium ions.
  6. 10. failure to maintain tension in muscle fibers
  7. 11. name of protein which is present inside the gap between the transverse tubules and the lateral sacs. They are responsible for altering the permeability of calcium ions into lateral sacs
  8. 13. one of 3 proteins which compose the thin filaments in sarcomeres (has 3 binding sites for proteins associated with the thin filament and Ca2+)
  9. 14. name of element which in ion form, will attach to troponin and reveal actin binding sites
  10. 18. (2 words) enlarged part of the sarcoplasmic reticulum come within the vicinity of transverse tubules
  11. 20. occurs after intense earercise when glycogen and creatine phosphate is replenished
  12. 25. one of 3 proteins which compose the thin filaments in sarcomeres (form a double helix of cytoskeletal protein chains)
