Morphology
The term is fully compositional: 'oculomotor' denotes eye movement/control and 'nerve' denotes a bundle transmitting impulses, so together they literally mean the nerve that controls eye muscles. This follows standard biomedical naming patterns (e.g. nervio oculomotor, nerf oculomoteur) and would be understandable to a B1 learner who already knows both constituents.
Etymology
Oculomotor nerve comes from old words meaning 'eye mover': oculo means 'eye' and motor means 'mover'. That's why the name refers to the nerve that sends signals to most of the eye muscles and so controls the eye's movements.
