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.
The arachnoid mater makes arachnoid villi, small protrusions through the dura mater into the venous sinuses of the brain, which allow CSF to exit the subarachnoid space and enter the blood stream. Unlike the dura mater, which receives a rich vascular supply from numerous arteries, the arachnoid mater is avascular (lacking blood vessels).
The anterior cerebral artery forms the anterolateral portion of the circle of Willis, while the middle cerebral artery does not contribute to the circle. The right and left posterior cerebral arteries arise from the basilar artery, which is formed by the left and right vertebral arteries. The vertebral arteries arise from the subclavian arteries.

The anterolateral central arteries or lenticulostriate arteries [3] (also anterolateral perforating arteries, anterolateral ganglionic arteries, striate arteries, or lateral striate arteries; latin aa. centrales anterolaterales, [4] or aa. lenticulostriatae [4]) are a group of small arteries mostly arising from (the initial M1 part of) the middle cerebral artery that enter the brain through ...
Arteries of the brain. Anterior cerebral artery labeled at the left (twice) The anterior cerebral artery is divided into 5 segments. Its smaller branches: the callosal (supracallosal) arteries are considered to be the A4 and A5 segments. [1] [2] A1 originates from the internal carotid artery and extends to the anterior communicating artery (AComm).
The internal carotid artery is an artery in the neck which supplies the anterior and middle cerebral circulation. [ 1 ] In human anatomy, the internal and external carotid arise from the common carotid artery , where it bifurcates at cervical vertebrae C3 or C4.
