Morphology
The meaning is directly compositional: 'motor' (relating to movement), 'nerve' and 'fiber' combine to indicate a nerve fiber involved in motor function. This follows ordinary English noun-modifier patterns and is cross-linguistically regular, so a B1 learner who knows the constituents can infer the meaning.
Etymology
Motor nerve fiber paints a simple image: a thin fiber from a nerve that works like a tiny motor cable carrying orders from the brain to a muscle. So, it means a nerve thread that sends signals to cause 'movement' or 'action'.
