Document Summary

Specify the functions of skeletal muscle tissue. Describe the organization of muscle at the tissue level. Explain the characteristics of skeletal muscle fibers, and identify the structural components of a sarcomere. Identify the components of the neuromuscular junction, and summarize the events involved in the neural control of skeletal muscle contraction and relaxation. Describe the mechanism responsible for tension production in a muscle fiber, and compare the different types of muscle contraction. Describe the mechanisms by which muscle fibers obtain the energy to power contractions. Identify the structural and functional differences between skeletal muscle fibers and cardiac muscle cells. Identify the structural and functional differences between skeletal muscle fibers and smooth muscle cells, and discuss the roles of smooth muscle tissue in systems throughout the body. Describe the arrangement of fascicles in the various types of muscles, and explain the resulting functional differences. Describe the classes of levers, and explain how they make muscles more efficient.
