    A second century Greek physician Galen was the first to use the word 'ganglion' in relation to a nerve complex. Now I'm rusty, but it is my understanding that the terms preganglionic and postganglionic developed to explain where along the synapse chain you were referring to.

    The postganglionic neuron is a motor neuron that forms a synapse with one or more preganglionic motor neurons, is located outside the central nervous system, and has its unmyelinated axon ending in smooth muscle, cardiac muscle tissue, or a gland. I wasn't aware the name had changed in any official capacity. It is also sometimes referred to as the peripheral neuron. Hope this helps.
