The artery supplies a portion of the frontal lobe and the lateral surface of the temporal and parietal lobes, including the primary motor and sensory areas of the face, throat, hand and arm, and in the dominant hemisphere, the areas for speech.
The cerebral veins drain the brain parenchyma and are located in the subarachnoid space. They pierce the meninges and drain further into the cranial venous sinuses.The cerebral veins lack muscular tissue and valves.The cerebral venous system can be divided into: medullary veins-they are numerous and originate 1-2 cm below cortical gray matter and pass through deep medullary white matter and drain into subependymal veins.
