Morphology
preganglionic = ganglionic (semi-transparent) = pre + ganglion + ic
The word is transparently formed by adding pre- to the adjective 'ganglionic' to indicate location or occurrence before the ganglion.
Etymology
Preganglionic used as a noun comes from pre- 'before' and ganglion 'a knot or small group of nerve cells'. So the word names a nerve cell or fiber that sits 'before' a ganglion and sends signals to it.
