What are the four main arteries supplying the brain?
The brain receives blood from two sources: the internal carotid arteries, which arise at the point in the neck where the common carotid arteries bifurcate, and the vertebral arteries (Figure 1.20). The internal carotid arteries branch to form two major cerebral arteries, the anterior and middle cerebral arteries.

Where is the anterior communicating artery located in the brain?
The anterior communicating artery (AComm) is a short, slender vessel that runs horizontally between the anterior cerebral arteries. The vessel crosses the ventral aspect of the median longitudinal fissure and is located anterior to the optic chiasm and posteromedial to the olfactory tracts.
Which is part of the cerebral artery supply the thalamus?
Anterior communicating artery: This is a very short single artery. It connects the left and right anterior cerebral arteries to each other. Striate arteries: These are the terminal branches of the middle cerebral artery. They supply the internal capsule, thalamus and the basal ganglia (basal nuclei).
