In either the sympathetic (dotted line) or the parasympathetic (solid line) nervous systems, the axon of the neuron leaving the central nervous system, changes the neuron once before innervating the effector.  The synapse between these two neurons is called the (autonomic) ganglion.  The (black-colored) neuron from the central nervous system to the the (autonomic) ganglion is called the pre-ganglionic neuron.  The (pink-colored) neuron from the (autonomic) ganglion to the effector, is called the post-ganglionic neuron.  The axons of the pre-ganglionic and post-ganglionic neurons are respectively the pre- and post- ganglionic fibers.<br>
交感神経(点線)と、副交感神経(実線)のいずれの系においても、中枢神経から出た神経細胞の軸索は、効果器を支配する前に、一度神経細胞をかえます。この神経細胞間のシナプス接合部を、(自律)神経節とよびます。中枢神経系より出て(自律)神経節にいたる(黒色の)神経細胞を節前神経細胞、(自律)神経節より出て効果器にいたる(ピンク色の)神経細胞を節後神経細胞とよびます。節前神経細胞、節後神経細胞の軸索が、それぞれ節前線維、節後線維です。

The representative ganglia of the sympathetic nervous system is the sympathetic trunk.  The sympathetic trunk locates on both sides of the spinal cord.  The ganglia of the para-sympathetic nerves often locates inside (or close to) the innervated organs.
 
 
交感神経の代表的な神経節が、交感神経幹です。交感神経幹は、脊髄の両側に位置しています。副交感神経の神経節は、支配する臓器内(あるいは近く)にあることが多いです。

In either the sympathetic (dotted line) or the parasympathetic (solid line) nervous systems, the axon of the neuron leaving the central nervous system, changes the neuron once before innervating the effector. The synapse between these two neurons is called the (autonomic) ganglion. The (black-colored) neuron from the central nervous system to the the (autonomic) ganglion is called the pre-ganglionic neuron. The (pink-colored) neuron from the (autonomic) ganglion to the effector, is called the post-ganglionic neuron. The axons of the pre-ganglionic and post-ganglionic neurons are respectively the pre- and post- ganglionic fibers.

The representative ganglia of the sympathetic nervous system is the sympathetic trunk. The sympathetic trunk locates on both sides of the spinal cord. The ganglia of the para-sympathetic nerves often locates inside (or close to) the innervated organs.
