Why is the axon of a ganglionic neuron called a postganglionic fiber?

Away from the ganglion The axon of a ganglionic neuron is called a postganglionic fiber because it carries impulses. an accumulation of extracellular fibrillar proteins and abnormal dendrites and axons. A "ganglion" is essentially a living relay. The inputs are "pre-ganglionic" and the outputs are "post-gangionic." Simple.
