Middle cerebral artery (MCA), which supplies blood to the majority of the lateral portion of the brain, including the temporal and lateral-parietal lobes. [ 2 ] [ 3 ] It is the largest of the cerebral arteries and is often affected in strokes [ 4 ]
In brain tissue, a biochemical cascade known as the ischemic cascade is triggered when the tissue becomes ischemic, potentially resulting in damage to and the death of brain cells. Medical professionals must take steps to maintain proper CBF in patients who have conditions like shock , stroke , cerebral edema , and traumatic brain injury .

The aorta (/ eɪ ˈ ɔːr t ə / ay-OR-tə; pl.: aortas or aortae) is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac arteries).
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 posterior communicating artery is given off as a branch of the internal carotid artery just before it divides into its terminal branches - the anterior and middle cerebral arteries. 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 M1 segment perforates the brain with numerous anterolateral central (lateral lenticulostriate) arteries, which supply the basal ganglia. M2: Extending anteriorly on the insula, this segment is known as the insular segment. It is also known as the Sylvian segment when the opercular segments are included.
The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum , a part of the brain . Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome .
