In both the sympathetic (dotted line) and parasympathetic (solid line) nervous systems, the axon (nerve fiber) 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 (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 the pre- and post-ganglionic fibers, respectively.<br> | |||
