Chapter 10
Objectives
1. State the layers and skeletal muscle connective tissue in relationship muscle groups, fascicles, and fibers.
2. List the functions of skeletal muscle.
3. Diagram and label a typical section of skeletal muscle.
4. Outline the events of muscle contraction starting with an action potential to the pulling of the myosin heads.
5. Describe the physiological relationship of length to the force of contraction.
6. Describe the two mechanisms for the control of skeletal muscles.
7. Interpret the physiological differences between treppe, wave summation, tetanus, and fatigue.
8. List the muscle requirements for ATP.
9.Differentiate between anaerobic and aerobic glycolysis with regard to ATP production and metabolic by-products.
10. Explain how tone seems to contradict skeletal muscle as voluntary and "all or none principle".
11. Differentiate between fast twitch and slow twitch muscles.
12. Compare and contrast skeletal muscle to smooth muscle and cardiac muscle.
13. Compare multi-unit smooth muscle to visceral smooth muscle.
14. Outline the various muscular diseases mentioned in lecture.
15. State five aspects to how muscles are named and provide an example for each.
16. Diagram and provide an example for the three types of levers.
17. Define selected muscles as antagonists, synergists, or fixators.
