Figure 10-3. Diagram of the contents of the cavernous sinus. The wall of the cavernous sinus contains the
ophthalmic (CN V-1) and maxillary (CN V-2) divisions of the trigeminal nerve (CN V) and the trochlear (CN IV)
and oculomotor (CN III) nerves. The siphon of the internal carotid artery and the abducent nerve (CN VI) along
with postganglionic sympathetic fibers lie within the cavernous sinus. (Reprinted with permission from Fix JD:
