Cranial nerve IV (the trochlear nerve) is primarily responsible for motor functions, specifically controlling the superior oblique muscle of the eye. Like cranial nerves XI (the accessory nerve) and XII (the hypoglossal nerve), it primarily carries somatic motor impulses, which are involved in the control of muscle movements.
