Quizplus · Accepted Answer

The major neurotransmitter for sympathetic autonomic activation is norepinephrine, which is released by sympathetic nerves and the adrenal gland during times of stress or physical activity. It increases heart rate, blood pressure, and respiration, and triggers the "fight or flight" response. Acetylcholine is the main neurotransmitter for the parasympathetic nervous system, while dopamine and serotonin are primarily involved in the regulation of mood, attention, and pleasure.
