Question

Quizplus · Accepted Answer

The sympathetic nervous system primarily uses norepinephrine to exert its actions. While acetylcholine is used in the preganglionic neurons of both the sympathetic and parasympathetic nervous systems, in the postganglionic neurons of the sympathetic system, it is predominantly norepinephrine that is used as a neurotransmitter. GABA and dopamine are not typically associated with the sympathetic nervous system.
