proximal to a ganglion.

pre·gan·gli·on·ic

(prē'gang-glē-on'ik),
Situated proximal to or preceding a ganglion; referring specifically to the preganglionic motor neurons of the autonomic nervous system (located in the spinal cord and brainstem) and the preganglionic, myelinated nerve fibers by which they are connected to the autonomic ganglia.

(prē-găng′glē-ŏn′ĭk)
adj.
Of, relating to, or being the nerve fibers that supply a ganglion, especially a ganglion of the autonomic nervous system.
