Quiz: Introduction to the Muscular System

  1. All movement in the body is the result of muscle contraction without exception.
  2. In addition to movement, muscle contraction also fulfills some other important functions in the body, such as posture, joint stability, and heat production.
  3. Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue.
  4. Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the endomysium.
  5. Skeletal muscle cells (fibers), unlike other body cells, are hard and strong.
  6. Tendon is formed by the epimysium, perimysium, and endomysium that extend beyond the fleshy part of the muscle.
  7. Smooth muscle, attached to bones, is responsible for skeletal movements.
  8. Cardiac muscle, found in the walls of the heart, is under control of the autonomic nervous system.
