Across
- 2. Paralyzes and relaxes muscles
- 5. Have enough O2
- 7. Not enough O2
- 8. Decrease muscle use
- 10. Fiber fully contracts or doesn't at all
- 13. Like string cheese
- 14. potential Acetylcholine attaches to receptors on muscle and electric current is formed
- 15. The fusion of many rapid nerve impulses into one smooth contraction
- 16. The two types of protein in muscles are Myosin and Actin
- 17. They are excitable, are elastic,contract,and extend.
- 18. Make up muscle fibers
- 21. Genetic causes degeneration of muscles
- 24. Also called muscle cell
- 26. Energy+P+APP ->
- 28. Uncontrolled contraction
- 29. Occurs mostly where muscles are weak
- 30. More moveable end of muscle
- 31. Less movable end of muscle
Down
- 1. The kind of muscle skeletal muscle is
- 3. Spasm of diaphragm
- 4. Maintains homeostasis by movement, maintain posture and body temperature
- 6. Used in South America from a plant that blocks Acetylcholine receptors on muscles
- 9. Increase the number of Actin and Myosin filaments which increase muscle size
- 11. Muscle that runs through cheek
- 12. Muscles become stiff several hours after death
- 19. Shiny layer on outside of muscle
- 20. Muscle that straightens a limb when it contracts, increasing angle between bones
- 22. Caused by overuse, dehydration, or K/Ca/Mg are too low
- 23. Muscle that bends a limb when it contracts, reducing angle between bones
- 25. Functional unit of muscle cells, make up Myofibrils
- 27. Muscle in the inner thigh
