Muscular System

3. muscle fibres that produce most of its energy aerobically for the prolonged generation of power.
5. one of hundreds of thousands of cylindrical subunits that make up a skeletal muscle cell
6. striated, voluntary muscle tissue
7. a group of several hereditary conditions in which the skeletal muscles degenerate, lose strength and are gradually replaced by fatty and fibrous tissue
8. chronic muscular pain and tenderness associated with fatigue, can be caused by infections diseases, trauma or medications
10. a high-energy compound that regenerates ATP in muscle cells
11. protein that makes up the thick filament in a muscle fibre
14. reduction in size, tome, and power of a muscle
16. an explanation for muscle contraction based on the movement of actin filaments in relation to myosin filaments
17. protein that makes up the thin filament in a muscle fibre

1. skeletal muscle cell
2. muscle fibres that produces most of its energy anaerobically, for the rapid generation of power. Vulnerable to fatigue.
4. one of many microscopic, string-like structures, composed of actin and myosin.
9. muscular contraction that lasts a fraction of a second
10. striated, involuntary muscle found only in the heart
12. ATP
13. exercise-induced increase in muscle mass due to increase in size, not number, of muscle fibres
15. non-striated, involuntary muscle tissue found in walls of internal organs
