Myofibrils account for roughly 80% of cellular volume, and are the contractile elements of the muscle cell. Myofibrils consist of repeating units called sarcomeres (the contractile unit of the myofibril), which have overlapping myofilaments connected to Z discs at either end of the sarcomere.
After studying part II of this chapter you should be able to: 1. Discuss how contractile force is regulated. 2. Describe the difference between a twitch, wave summation, tetany, and treppe in muscle. contraction. 3. Describe the difference between isometric and isotonic contractions. 4. Discuss the length tension relationship of skeletal muscle. 5. Describe the energy requirements of skeletal muscle and the creatine phosphate system.
