Exercise and reactions to exciting stimuli include

increased activity in the sympathetic, and decreased activity in the parasympathetic divisions

Explanation:

Increased activity of sympathetic division and decreased activity in the parasympathetic division.

Explanation:

The parasympathetic division of autonomous nerve system is responsible for maintenance of normal activities at resting stage. The sympathetic division of autonomous nerve system is involved in fight or flight response. It is associated with activities under stressful or emergency conditions. Hence, exercise and reactions to exciting stimuli activate the sympathetic division and deactivate the parasympathetic division.
