____________________________________________________
Learning Outcomes
LO 9.4.3 Describe the steps of a cross bridge cycle. 9.5Temporal summation and motor unit recruitment allow smooth, graded skeletal muscle contractions LO 9.5.1 Define motor unit and muscle twitch, and describe the events occurring during the three phases of a muscle twitch. LO 9.5.2 Explain how smooth, graded contractions of a skeletal muscle are produced. LO 9.5.3 Differentiate between isometric and isotonic contractions. 9.6ATP for muscle contraction is produced aerobically or anaerobically LO 9.6.1 Describe three ways in which ATP is regenerated during skeletal muscle contraction. LO 9.6.2 Define EPOC and muscle fatigue. List possible causes of muscle fatigue. 9.7The force, velocity, and duration of skeletal muscle contractions are determined by a variety of factorS 9.7.2 Describe three types of skeletal muscle fibers and explain the relative value of each type. 9.8How does skeletal muscle respond to exercise? LO 9.8.1 Compare and contrast the effects of aerobic and resistance exercise on skeletal muscles. 9.9Smooth muscle is nonstriated involuntary muscle LO 9.9.1 Compare the gross and microscopic anatomy of smooth muscle cells to that of skeletal muscle cells. LO 9.9.2 Compare and contrast the contractile mechanisms and the means of activation of skeletal and smooth muscles. LO 9.9.3 Distinguish between unitary and multi unit smooth muscle structurally and functionally.
