Morphology
duction = duc + tion
The anatomical meaning is a specialized technical sense and is not transparently derived for an average learner from the combining form 'duc' + '-tion'.
Etymology
Duction comes from the Latin ducere 'to lead', the same root you see in conduct. In medicine duction means how a limb is 'led' toward or away from the middle of the body, which is why therapists check it to see how well a joint moves.
