Describe the connective tissue layers associated with skeletal muscle tissue. Describe the structural components of a sarcomere. Describe the components of thin filaments and thick filaments, and then describe the sliding filament theory. Explain the interrelated steps that occur within the muscle contraction cycle. Explain the key concepts involved in the length-tension relationship. Define isotonic contraction and isometric contraction, and then compare the two types. Describe the arrangement of fascicles in parallel muscle, convergent muscle, pennate muscle, and circular muscle. What functional differences result from these different arrangements? Define a lever, and describe the three classes of levers. How do levers affect muscle efficiency? Define axial muscles then list the principal axial muscles. Define appendicular muscles and list the principle appendicular muscles.
