Ten of the twelve pairs of cranial nerves either target or are sourced from the brainstem nuclei.<ref name="Purves">{{cite book|last1=Purves|first1=Dale|title=Neuroscience|date=2011|publisher=Sinauer|location=Sunderland, Mass.|isbn=978-0-87893-695-3|edition=5th.}}</ref>{{rp|725}} The nuclei of the oculomotor nerve (III) and trochlear nerve (IV) are located in the midbrain. The nuclei of the trigeminal nerve (V), abducens nerve (VI), facial nerve (VII) and vestibulocochlear nerve (VIII) are located in the pons. The nuclei of the glossopharyngeal nerve (IX), vagus nerve (X), accessory nerve (XI) and hypoglossal nerve (XII) are located in the medulla. The fibers of these cranial nerves exit the brainstem from these nuclei.<ref name="Vilensky">{{cite book|title=The Clinical Anatomy of the Cranial Nerves: The Nerves of 'On Olympus Towering Top'|last1=Vilensky|first1=Joel|last2=Robertson|first2=Wendy|last3=Suarez-Quian|first3=Carlos|publisher=Wiley-Blackwell|year=2015|isbn=978-1-118-49201-7|location=Ames, Iowa}}</ref>
