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
Middle cerebral artery Middle cerebral artery The middle cerebral artery (MCA) is one of the three major paired arteries that supply blood to the cerebrum. The MCA arises from the internal carotid and continues into the lateral sulcus where it then branches and projects to many parts of the lateral cerebral cortex. It also supplies blood to the anterior temporal lobes and the insular cortices. The left and right MCAs rise from trifurcations of the internal carotid arteries and thus are connected to the anterior cerebral arteries and the posterior communicating arteries, which connect to the posterior cerebral arteries. The MCAs are not
