The (or '''lateral stellar compartment''') is a large collection of thin-walled
Vein s creating a cavity bordered by the
Sphenoid Bone and the
Temporal Bone of the
Skull .
Each cavernous sinus (one for each hemisphere of the brain) contains the
Internal Carotid Artery , its
Sympathetic Plexus , the
Oculomotor ,
Trochlear , and
Abducens Nerve s.
In addition, the
Ophthalmic and
Maxillary Branches of the
Trigeminal Nerve traverses the cavernous sinus.
It is the only anatomic location in the body in which an
Artery travels completely through a venous structure.
