8.1 Introduction
1. List various outcomes of muscle actions.

8.2 Structure of a Skeletal Muscle
2. Identify the structures that make up a skeletal muscle.
3. Identify the major parts of a skeletal muscle fiber, and the function of each.
4. Discuss nervous stimulation of a skeletal muscle.

8.3 Skeletal Muscle Contraction
5. Identify the major events of skeletal muscle fiber contraction.
6. List the energy sources for muscle fiber contraction.
7. Describe how oxygen debt develops.
8. Describe how a muscle may become fatigued.

8.4 Muscular Responses
9. Distinguish between a twitch, recruitment, and a sustained contraction.
10. Explain how muscular contractions move body parts and help maintain posture.

8.5 Smooth Muscle
11. Distinguish between the structures and functions of multiunit smooth muscle and visceral smooth muscle.
12. Compare the contraction mechanisms of skeletal and smooth muscle fibers.

8.6 Cardiac Muscle
13. Compare the contraction mechanisms of cardiac and skeletal muscle fibers.

8.7 Skeletal Muscle Actions
14. Explain how the attachments, locations, and interactions of skeletal muscles make different movements possible.

8.8 Major Skeletal Muscles
15. Identify and locate the major skeletal muscles of each body region.
16. Identify the actions of the major skeletal muscles of each body region.
