Not only responsible for well-defined biceps, this system is needed for several other body systems to function properly.
  1. The nervous system.
  2. The endocrine system.
  3. The muscular system.
Explanation
Answer: C -The muscular system is not only what gym rats proudly show-off; with its three kinds of muscle tissue it is needed in almost all body functions. Visceral or smooth muscle is the muscle cells found in hollow organs and blood vessels. Nonstriated (non-banded) muscle is innervated by the nerves that control involuntary movement. Constriction of blood vessels, the peristalsis in the digestive track, and uterine contractions are examples of this. Skeletal muscle tissue is responsible for movement and posture. It is striated (banded) and under voluntary control. Cardiac muscle tissue is what forms the heart walls. It is a specialized striated muscle cell under involuntary control.
