With such similar-sounding words, it can be tough to remember the difference between afferent and efferent . That’s why it’s important to focus on the difference in what they do first.

The traffic can only flow in one direction – afferent neurons only take information to the central nervous system, and efferent neurons only take it away from the central nervous system.
