Muscle Chapter 8

3. layers of dense connective tissue
5. in red blood cells carries oxygen to muscle tissue
8. the layer of connective tissue around each skeletal muscle
10. consists of two twisted strands, with globular heads projected outward along the strands
12. the center of the A band which consists of myosin filaments only
13. skeletal muscle fibers contract only when stimulated by a
14. the cell membrane of a muscle fiber
16. a complete breakdown of glucose; it is aerobic (requires oxygen) and occurs in the mitochondria
18. the first phase of cellular respiration; it is anaerobic and occurs in the cytoplasm
19. the organization of filaments produces bands called
20. myofibrils are made up of many units called
22. the neurotransmitter for skeletal muscle fiber contraction at the neuromuscular junctions
24. made up of overlapping thick and thin filaments
25. movement requires
26. stores oxygen in muscle tissue for aerobic respiration; this increases oxygen availability

1. after the nerve impulse stops, these events lead to_________of the muscle
2. each muscle cell (fiber) is covered by a connective tissue layer called
4. in the center of the H zone, consists of proteins that hold the myosin filaments in place
6. the neuron communicates with the muscle fiber by way of chemicals called
7. a globular protein arranged in twisted filaments (a double helix), containing myosin binding sites
9. the gap between the membranes of the neuron and muscle fiber
11. the cytoplasm of a muscle cell
15. bundles of skeletal muscle fibers
17. broad sheets of connective tissue
21. the neurotransmitter for skeletal muscle fiber contraction at the neuromuscular junctions
23. made up of actin filaments, which are anchored to the Z lines
