Muscles

4. these increase the angle between ventral surfaces
6. connective tissue surrounding individual muscle fibers
11. nerve cells that conduct impulses towards the CNS
15. nerve cells that conduct impulses away from the CNS
16. any of the alternate dark and light cross bands of a myofibril of striated muscle
18. type of muscle tissue that helps the heart pump, involuntary
19. muscles always do this and get shorter
21. these decrease the angle between ventral surfaces
22. the attachment of a muscle moves during movement
24. external connective tissue sheath around a whole muscle
25. contractile protein that makes up the thick filaments in muscle fibers

1. explanation of how thick and thin filaments slide relative to one another during muscle contraction to decrease sarcomere length
2. contractile protein that is part of the thin filaments in muscle fibers
3. protein of muscle that forms a complex with troponin regulating the interaction of actin and myosin
5. any of the repeating structural units of striated muscle fibrils
7. aka muscle cell aka muscle fiber
8. type of muscle tissue that lines hollow organs, involuntary
9. type of muscle tissue that surrounds bones, voluntary
10. to shorten and thicken
12. network of interlacing blood vessels or nerves
13. a small bundle of muscle fibers
14. protein of muscle that together with tropomyosin forms a regulatory protein complex that ocntrols the interaction of actin and myosin
17. the attachment of a muscle that stays stationary during movement
20. connective tissue surrounding a fascicle
23. an organ composed of one or three types of tissue (skeletal, smooth, or cardiac), specialized for contraction
