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。
