What arteries are responsible for the blood supply to 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.

Symptoms of restricted blood flow to the back of the brain, also called vertebrobasilar insufficiency, include dizziness and slurred speech.

How does blood flow out of the brain?

The vertebrobasilar system sends many small branches into the brain stem and branches off to form the posterior cerebellar and posterior meningeal arteries, which supply the back third of the brain. The jugular and other veins carry blood out of the brain.
