Before entering the fissure, the MCA bifurcates and these branches ramify over the insula.

Almost the entire lateral surface of the cerebral hemisphere is supplied by the middle cerebral artery (MCA), emerging from the lateral sulcus. The MCA supplies the most anterior part of the temporal pole also. The tentorial part of the inferior surface is mainly supplied by cortical branches of the posterior cerebral artery. The medial half of the orbital surface (orbital part of inferior surface) is supplied by cortical branches of the anterior cerebral artery. Nabeel Kouka, MD, DO, MBA www.brain101.info. 1. The derivatives of the internal carotid arteries form the anterior blood supply (anterior circulation) of the brain, which includes the anterior and middle cerebral arteries . The medial surface is supplied by both anterior cerebral (ACA) and posterior cerebral (PCA) arteries. The anterior cerebral arteries from each hemisphere join via the anterior commuincating artery. It divides into a number of branches that supply the insula, emerge from the lateral sulcus, and spread out to supply most of the lateral surface of the cerebral hemisphere. Surrounded by the cerebral hemispheres, the diencephalon forms the central core of the brain. Anterior cerebral artery: Medial part of the orbital surface of the frontal lobe is supplied by the anterior cerebral artery. Blood supply. Supplies most of cortex on the anterior medial surface of the brain, from the frontal to the anterior parietal lobes, usually including the medial sensorimotor cortex (i.e., the sensory cortex for the lower extremity). The posterior cerebral Anatomy of cerebral hemisphere The cerebral hemispheres make up the largest portion of the human brain. Cortical branches of the anterior cerebral artery supply the medial surface of the hemisphere as far back as the parietooccipital sulcus ( Table 5.1 ). Exits at the top of the basilar artery and dives back into the midline; wraps up and posteriorly to supply small portion of the parietal lobe and all of the occipital cortex Branches over and According to Bouthillier (1996) 2 the ICA can be divided into seven The middle cerebral artery (MCA) begins at the ICA bifurcation and courses into the Sylvian fissure. The medial surface of the cerebral hemisphere is also supplied by all the three cerebral arteries: Anterior cerebral artery: Most of the medial surface is supplied by the anterior Anterior Cerebral Artery. The Internal Carotid Arteries and Vertebral Arteries Supply the Brain. The paracentral lobule controls motor and sensory innervations of the contralateral lower extremity. After receiving the posterior communicating branch from the ICA, the PCA continues along the medial surface of the corresponding cerebral hemisphere, beneath the Paracentral lobule is on the medial surface of the hemisphere and is the continuation of the precentral gyrus and postcentral gyrus. the convex surface of the cerebral hemisphere.
