And at the end of that second, postganglionic neuron, the fiber releases a different neurotransmitter.

在那一秒钟的末尾，节后神经元，纤维会释放不同的神经递质。

But in your parasympathetic system, the postganglionic neurons release ACh at their synapses with the effector organs, too as opposed to in the sympathetic system, where effectors get a dose of norepinephrine instead.

但是在你的副交感神经系统中，节后神经元在它们与效应器官的突触处释放 ACh，而在交感神经系统中，效应器官得到一剂去甲肾上腺素。

Those postganglionic neurons then carry the action potential to the effector organs — in this case, let's say your leg muscles, which are going to need an influx of blood if they're going to hustle you out of that house.

节后神经元然后将动作电位传递到效应器官——在这种情况下，比方说你的腿部肌肉，如果它们要把你赶出房子，它们需要大量的血液。
