Muscular system
Across
- 4. denoting a dense band that connects cardiac muscle cells
- 6. protein thick muscle filaments
- 8. wavelike motion which helps force the contents of tubular organs along, e.g. intestines
- 11. muscles which work together to complete a movement
- 15. relatively immovable end of skeletal muscle
- 18. type of muscle cells which twitch for longer than skeletal muscle cells
- 20. functional unit of muscle contraction; causes striation
- 23. process by which the forces of individual twitches combine
- 24. threadlike structures within the sarcoplasm
- 25. denoting sustained muscular contraction
- 27. movement which increases the angle
- 28. layer of connective tissue that separate muscle tissue into fascicles
- 29. layer of thin connective tissue
- 30. increase in the number of motor units being activated during a contraction
- 31. movement which decreases the angle
- 32. linkages formed between actin and myosin
Down
- 1. breaks down acetylcholine
- 2. protein in muscle cells that help maintain oxygen availability
- 3. agent which causes movement
- 5. recording of an electrically stimulated isolated muscle
- 7. type of self-exciting smooth muscle displaying rhythmicity
- 9. agent which oppose a movement
- 10. denoting material within a muscle fiber
- 12. type of muscle cells containing less organized filaments of actin and myosin
- 13. bundles of skeletal muscle fibers
- 14. single contraction reflecting stimulation of a muscle fiber
- 16. relatively movable end of skeletal muscle
- 17. thin muscle filaments
- 19. signal which stimulates a skeletal muscle fiber
- 21. protein which stops stem cells from developing into muscle cells
- 22. layer of connective tissue that closely surrounds each skeletal muscle
- 26. broad fibrous sheets of connective tissue
