Question

question@which of the following sympathetic structures are not adrenergic?answerall of the structures listed are adrenergic.most postganglionic terminals or fibersall preganglionic fibersmost ganglionic neuronsi dont know yet

Explanation:

Adrenergic structures release norepinephrine. Preganglionic fibers (both sympathetic and parasympathetic) release acetylcholine (cholinergic), not norepinephrine. Most postganglionic sympathetic terminals/fibers are adrenergic. Ganglionic neurons (in sympathetic ganglia) are part of the pathway where post - ganglionic fibers (adrenergic in most cases) originate.

Answer:

All preganglionic fibers
