The (blue-colored) efferent fiber of the somatic nervous system innervates the effector directly after leaving the central nervous system.  Meanwhile, in the autonomic nervous system (dashed lines), after the efferent fibers (black dashed line) leaves the central nervous system, it forms a synapse with a different (pink-colored) neuron outside of the central nervous system, and the fiber of that neuron (pink dashed line) innervates the effectors, such as internal organs.  Such a synapse of the autonomic nervous system, outside of the central nervous system, is called the autonomic ganglion. The (black) neuron, which left the central nervous system, is the neuron before the ganglion, and is thus called the pre-ganglionic neuron. The (pink) neuron, whose cell body is within the ganglion, is the neuron after the ganglion, and is thus called the post-ganglionic neuron.

遠心性の体性神経（青い実線）では、中枢神経を出た神経線維は、直接に骨格筋などの効果器を支配しています。一方、自律神経系（破線）では、中枢神経を出た神経線維（黒色の破線）は、中枢神経の外で（ピンク色の）他の神経細胞とシナプスを形成し、その神経細胞の線維（ピンク色の破線）が内臓などの効果器を支配しています。このような中枢神経の外にある自律神経系のシナプスを、自律神経節とよんでいます。中枢神経を出た（黒色の）神経は、自律神経節よりも前の神経であるので、「節前神経細胞」であります。自律神経節に細胞体があり、内臓などの効果器を支配している（ピンク色の）神経を、自律神経節よりも後の神経であるので、「節後神経細胞」です。

POINT!
The efferent fiber of the autonomic nervous system innervates the effector after forming a synapse at the autonomic ganglion.

The (blue-colored) efferent fiber of the somatic nervous system innervates the effector directly after leaving the central nervous system. Meanwhile, in the autonomic nervous system (dashed lines), after the efferent fibers (black dashed line) leaves the central nervous system, it forms a synapse with a different (pink-colored) neuron outside of the central nervous system, and the fiber of that neuron (pink dashed line) innervates the effectors, such as internal organs. Such a synapse of the autonomic nervous system, outside of the central nervous system, is called the autonomic ganglion. The (black) neuron, which left the central nervous system, is the neuron before the ganglion, and is thus called the pre-ganglionic neuron. The (pink) neuron, whose cell body is within the ganglion, is the neuron after the ganglion, and is thus called the post-ganglionic neuron.
