Carotid triangle Carotid triangle The carotid triangle (or superior carotid triangle) is a portion of the anterior triangle of the neck. It is bounded: It is (covered) by the integument, superficial fascia, Platysma and deep fascia; Its floor is formed by parts of the -1 Thyrohyoid membrane, -2Hyoglossus, and the -3Constrictores pharyngis medius and inferior. The external and internal carotids lie side by side, the external being the more anterior of the two. The following branches of the external carotid are also met with in this space: The veins met with are: ...all of which end in the internal jugular vein Superficial
Internal carotid artery on its lateral side is the abducent nerve, or cranial nerve VI. The named branches of the cavernous segment are: The cavernous segment also gives rise to small capsular arteries that supply the wall of the cavernous sinus. The clinoid segment, or C5, is another short segment of the internal carotid that begins after the artery exits the cavernous sinus at the proximal dural ring and extends distally to the distal dural ring, after which the carotid artery is considered "intra-dural" and has entered the subarachnoid space. The clinoid segment normally has no named branches, though the ophthalmic artery may
