Question

Quizplus · Accepted Answer

Most postganglionic sympathetic nerves release norepinephrine (also known as noradrenaline), which acts as a neurotransmitter and activates adrenergic receptors in the target tissues. Acetylcholine is released by most postganglionic parasympathetic nerves, while epinephrine (also known as adrenaline) is released by the adrenal medulla and some sympathetic nerve endings. Dopamine is not typically released by postganglionic sympathetic nerves, but rather by certain neurons in the brain and kidneys.
