CN are named (from I to XII) going down from midbrain to pons to medulla. CN XI is an exception, as its nucleus is in the cervical cord. Motor nuclei are medial in the brain stem, sensory are lateral. Although most CN innervate the ipsilateral side, CN IV loops around and innervates the contralateral superior oblique.
