By contrast, most parasympathetic ganglia are found way out from the spine — near, or even inside of their effector organs.

相比之下，大多数副交感神经节在远离脊柱的地方——靠近，甚至在它们的效应器官内部。

Since parasympathetic ganglia are so close to, or even inside of, their effector organs, the preganglionic fibers are a lot longer.

由于副交感神经节如此接近其效应器官甚至在它们的内部，节前纤维要长得多。

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。

And that one, in turn, leads to an effector organ, where it synapses again to create whatever response was signaled — like sending more blood to your skeletal muscles, or making your heart pump faster.

这根神经纤维又导致一个效应器官，在那里它再次突触以产生所发出的任何反应——比如向骨骼肌输送更多的血液，或者让你的心脏泵速加快。

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。
