FIGURE 18 Cranial nerves and brain stem arteries responsible for eye movement; nerves are shown in blue and blood vessels in gray. The oculomotor nucleus is located under the superior colliculus and gives rise to cranial nerve III that exits ventrally just above the pons. The trochlear nucleus is located under the inferior colliculus. Its axons cross contralaterally and leave the dorsal surface of the brain stem as cranial nerve IV. It then wraps around the lateral brain stem and runs close to nerve III. Note that these two nerves exit between two major arteries and can be damaged by cardiovascular problems. The abducens nucleus is located in the dorsal pons. Its axons exit the ventral surface of the brain stem medially and just below the pons. Cerebral vascular accidents in the nearby anterior inferior cerebellar artery compromise its function.
