10. Internal carotid arteriogram, AP projection
The cervical and petrous segments of the internal carotid artery have no branches.
Important branches are given off in the skull. The ophthalmic artery
arises from the internal carotid artery as it emerges from the cavernous sinus.
The posterior communicating artery (not visualized on this study) runs
backward to join the ipsilateral posterior cerebral artery. The anterior
cerebral artery, a terminal branch of the internal carotid, passes forward
between the cerebral hemispheres and winds around the corpus callosum. The
middle cerebral artery, the larger terminal branch of the internal carotid,
runs laterally in the lateral cerebral sulcus (sylvian fissure). (See Image
