Roots
Each has three roots entering the ganglion and a variable number of exiting branches.
- The motor root carries presynaptic parasympathetic nerve fibers (GVE) that terminate in the ganglion by synapsing the postsynaptic fibers traveling to target organs.
- The sympathetic root carries postsynaptic sympathetic fibers (GVE) that traverse the ganglion without synapsing.
- The sensory root carries general sensory fibers (GSA) that also do not synapse in the ganglion.
Some ganglia also carry special sensory fibers (SVA) for taste sensation.

“You know, honey, us colored folks is branches without roots and that makes things come round in queer ways.”
