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