View of the ventral surface of the brain depicting the sites of entry or exit of most of the cranial nerves. Note that the olfactory nerve (cranial nerve [CN] I) is not shown in this illustration and that the trochlear nerve exits the brainstem on the posterior surface and then passes along the exterior of the lower midbrain to enter the cavernous sinus along with CN VI.
