The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the: Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal lobes [1]
Cerebral circulation is the movement of blood through a network of cerebral arteries and veins supplying the brain. The rate of cerebral blood flow in an adult human is typically 750 milliliters per minute, or about 15% of cardiac output. Arteries deliver oxygenated blood, glucose and other nutrients to the brain.
The circle of Willis is a part of the cerebral circulation and is composed of the following arteries: [3] Anterior cerebral artery (left and right) at their A1 segments; Anterior communicating artery; Internal carotid artery (left and right) at its distal tip (carotid terminus) Posterior cerebral artery (left and right) at their P1 segments
Each posterior communicating artery is situated within the interpeduncular cistern, superolateral to the pituitary gland. [2]: 450 Each are is situated upon the medial surface of the ipsilateral cerebral peduncle [1]: 477 and adjacent to the anterior perforated substance.
The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous sinuses (channels) found between the periosteal and meningeal layers of dura mater in the brain. [ 1 ] [ 2 ] They receive blood from the cerebral veins , and cerebrospinal fluid (CSF) from the subarachnoid space via arachnoid granulations .
