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 ]
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).
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 leg area is located close to the midline, in interior sections of the motor area folding into the medial longitudinal fissure. The lateral, convex side of the primary motor cortex is arranged from top to bottom in areas that correspond to the buttocks, torso, shoulder, elbow, wrist, fingers, thumb, eyelids, lips, and jaw.
Anatomical variations of the anterior communicating artery are relatively common. The artery is sometimes duplicated, multiplicated, fenestrated ("net-like") or very short, giving the impression that two anterior cerebral arteries are fused at the point where the anterior communicating artery is usually expected to arise.

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 .
