The medial surface of the cerebral hemisphere is supplied by the following arteries: Anterior cerebral artery: The majority of the medial surface (anterior 2/3rd) is supplied by the anterior cerebral artery. Ventral Surface. The central sulcus also extends on the medial surface of the cerebral hemisphere. Ventral Surface of the Brain 2 layer of cells and cellular processes called the cerebral cortex.The surface of each hemisphere is highly infolded; the ridges thus formed are known as gyri (singular: gyrus) and the valleys are called sulci (singular: sulcus) or fissures (if they are especially deep).
