Uberon definition : The middle cerebral artery (MCA) is one of the three major paired arteries that supplies
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 considered a part of the Circle of Willis. [WP,unvetted].;
