Autonomic ganglia contain the cell bodies of motor neurons.

The autonomic nervous system (ANS) contributes to the stability of the internal environment of the body (homeostasis). The autonomic nervous system continuously makes adjustments to our body to maintain equilibrium. The ANS regulates cardiac and smooth muscles and glands. One example of the function of the autonomic nervous system is when our pupils constrict when bright light is shining into our eyes. There are two main branches of the autonomic nervous system, the sympathetic and parasympathetic.
