A network or interconnected collection of ganglia and their associated nerve fibers forming a complex neural junction system.
From ganglion + plexus (Latin 'plexus' meaning braid or network). This compound describes the interconnected web-like structure of multiple ganglia working together.
The solar plexus is perhaps the most famous ganglioplexus—it's a massive network of nerves behind your stomach that controls digestive and organ functions. When you get 'hit in the gut,' you're disrupting this ganglioplexus!
