answers: cerebrum
context: when present provides the "pre-Rolandic", "Rolandic", "anterior parietal", "posterior parietal" and the "angular artery" for irrigation instead of the "upper" and "lower trunks". The branches (ramus) of the MCA can be described by the areas that they irrigate. Areas supplied by the middle cerebral artery include: MCA occlusion site and resulting Aphasia Occlusion of the middle cerebral artery results in Middle cerebral artery syndrome, potentially showing the following defects: 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 </s> Posterior communicating artery In human anatomy, the left and right posterior communicating arteries are arteries at the base of the brain that form part of the circle of Willis. Each posterior communicating artery connects the three cerebral arteries of the same side. Anteriorly, it connects to the internal carotid artery (ICA) prior to the terminal bifurcation of the ICA into the anterior cerebral artery and middle cerebral artery. Posteriorly, it communicates with the posterior cerebral artery. The brain is supplied with blood by the internal carotid arteries and also by the posterior cerebral arteries; the posterior communicating arteries connects the </s> considered a part of the Circle of Willis. The middle cerebral artery can be classified into 4 parts: The M2 and M3 segments may each split into 2 or 3 main trunks (terminal branches) with an "upper trunk", "lower trunk" and occasionally a "middle trunk". Bifurcations and trifurcations occurs in 50% and 25% of the cases respectively. Other cases include duplication of the MCA at the internal carotid artery (ICA) or an accessory MCA (AccMCA) which arise not from the ICA but as a branch from the anterior cerebral artery. The "middle trunk" that exist in parts of the population,
question: which part of the cerebral hemisphere is supplied by the middle cerebral artery
