The '''Cavernous Portion of [[internal carotid artery]]'''.—In this part of its course, the artery is situated between the layers of the [[dura mater]] forming the [[cavernous sinus]], but covered by the lining membrane of the sinus. 

It at first ascends toward the [[posterior clinoid process]], then passes forward by the side of the body of the [[sphenoid bone]], and again curves upward on the medial side of the [[anterior clinoid process]], and perforates the dura mater forming the roof of the sinus. 

This portion of the artery is surrounded by filaments of the [[sympathetic nerve]], and on its lateral side is the [[abducent nerve]].
