PRACTICE QUESTIONS: MUSCLES AND MUSCLES TISSUE
1. Compare and contrast three types of muscle tissue: Skeletal, Cardiac, Smooth. Which ones are striated. Which of these work in a voluntarily manner
2. List the four major functions of muscle tissue
3. Discuss the properties of muscle tissue
4. Describe the following terms: Fascicles, Epimysium, Perimysium, Endomysium
5. Describe the following microscopic structure of the skeletal muscle fiber: sarcolemma, sarcoplasm, sarcoplasmic reticulum and sarcomeres (Z disc, A band, I band).
6. Describe the structure and function of the contractile proteins (actin and myosin) and regulatory proteins (troponin and tropomyosin). Mention the location of each protein within the myofibril.
7. Explain the sliding filament mechanism of muscle contraction and the changes in the bands and sarcomere during muscle contraction.
8. Outline the steps of the contraction cycle: ATP hydrolysis, cross bridge attachment, power stroke, and cross bridge detachment.
9. Describe the structures at the neuromuscular junction and the sequence of events leading to muscle contraction. (Include the roles of played by acetylcholine and Ca2+.
10. Describe the events during the latent period, contraction period, and relaxation period. Compare it to a wave summation, incomplete tetanus, and complete tetanus

15. Name one factor that can stimulate hypertrophy of the muscle fiber
16. Name the type of cells that retain the capacity to regenerate damaged muscle fiber
17. The number of skeletal muscle fibers is set before you are born. TRUE / FALSE
