Morphology

plexus + coccygeus

The compound is fully compositional: 'plexus' denotes a network of nerves/vessels and 'coccygeus' is an adjectival form relating to the coccyx, so the overall meaning ('network of nerves near the coccyx') is directly derivable from the parts. Although 'coccygeus' is a technical/rare form (not listed in the provided dictionary), its clear morphological link to 'coccyx' makes the expression transparent to a learner who knows both constituents.

Etymology

Plexus coccygeus comes from older words: plexus means a braided 'network' and coccygeus refers to the 'tailbone' because that bone was compared to a 'cuckoo's beak'. So the name gives the picture of a small braided 'network' of nerves near the tailbone, which is why it names that group of nerves.
