Root Explanation

Postganglionic → It is formed from "post-" (meaning after) and "ganglion" (from Greek "ganglion", meaning a swelling or knot, specifically referring to a cluster of nerve cell bodies). The term "postganglionic" refers to the fibers or neurons that are located after a ganglion in the autonomic nervous system.

Memory Tip

Think of 'post-' meaning 'after' and 'ganglion' referring to a 'knot' of nerve cells — so postganglionic describes the nerves that come after this knot.
