Nervous System Functions and Responses

The autonomic nervous system controls involuntary actions of internal organs. It has two divisions: sympathetic and parasympathetic. The sympathetic system prepares the body for emergencies, increasing heart rate and blood sugar, while the parasympathetic system stabilizes body functions post-emergency, helping the body return to normal.
