What are the divisions of the autonomic nervous system? *

The autonomic nervous system is divided into three parts: 1) the sympathetic nervous system; 2) the parasympathetic nervous system; and 3) the enteric nervous system. The parasympathetic and sympathetic nervous systems usually have opposing actions. For example, while the sympathetic nervous system controls the "fight or flight" responses, which increase the heart rate under stress, the parasympathetic nervous system will slow the heart rate. The enteric nervous system consists of nerve cells in the gastrointestinal tract.

  • The muscle of the arteries contracts and relaxes to regulate the blood pressure and the flow of blood.

Functions of Skeletal Muscle Tissue
  • Skeletal muscles function in pairs to bring about the co-ordinated movements of the limbs, trunk, jaws, eyeballs, etc.
  • Skeletal muscles are directly involved in the breathing process.


Functions of Cardiac (Heart) Muscle Tissue
  • Cardiac muscle tissue plays the most important role in the contraction of the atria and ventricles of the heart.
  • It causes the rhythmical beating of the heart, circulating the blood and its contents throughout the body as a consequence.
