Morphology

autonomic + ganglion

The phrase is a straightforward composition: 'autonomic' (relating to involuntary physiological regulation) modifies 'ganglion' (a mass of nerve cells), so the combined meaning — a ganglion belonging to the autonomic nervous system that relays signals — follows directly from the constituents. Although technical, this is a literal, compositional medical term and parallels similar constructions across languages, so a learner who knows both words can infer the MWE's meaning.

Etymology

Autonomic ganglion comes from older words: autonomic means 'works by itself' and ganglion originally meant a 'knot' or small group. Think of a small knot or station of nerve cells that 'passes messages' to the body's organs, so the name refers to a group of nerve cells that 'relays signals' to internal organs.
