When do the sympathetic and parasympathetic divisions cooperate with, rather than antagonize, one another?

Answer: During sexual activity

Explanation: The two divisions of the autonomic nervous system are the sympathetic division and the parasympathetic division. The sympathetic nervous system prepares the body for the "fight or flight" response during any potential danger while the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state. The sympathetic and parasympathetic divisions cooperate with each other during sexual activity when male sexual response reflects a dynamic balance between exciting and inhibiting forces of the autonomic nervous system within the penis and throughout the Central nervous systems while the sympathetic component tends to inhibit erections, whereas the parasympathetic system is one of several excitatory pathways.
