SECTION 5.2 - SKELETAL MUSCLE ACTIONS (pg 162-170)
LESSON OBJECTIVES:
1. Describe a motor unit & explain the functional differences between motor units that contain large & small numbers of muscle fibers.
2. Explain how a nerve impulse generates an action potential in a muscle fiber.
3. Explain how muscle contraction occurs at the level of the sarcomere.
4. Describe the differences between slow-twitch & fast-twitch skeletal muscle fibers.
5. Discuss the concepts of muscular strength, power, & endurance.
