The basilar artery (U.K.: / ˈ b æ z. ɪ. l ə /; [1] [2] U.S.: / ˈ b æ s. ə. l ər / [3]) is one of the arteries that supplies the brain with oxygen-rich blood.. The two vertebral arteries and the basilar artery are known as the vertebral basilar system, which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of ...
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]
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 cistern contains the origin of the abducens nerve (CN VI), [1] [3] the basilar artery [3] and the origin of the basilar artery and of its branches, [1] and the anterior inferior cerebellar artery, and superior cerebellar artery. [1] [3]
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 brain is supplied with blood by the internal carotid arteries and also by the posterior cerebral arteries; the posterior communicating arteries connects the two systems. This provides redundancies or collaterals in the cerebral circulation so that, if one system is blocked or narrowed, the other can take over.
The arteries of the base of the brain. Superior cerebellar artery labeled near center. The temporal pole of the cerebrum and a portion of the cerebellar hemisphere have been removed on the right side (left half of diagram). Inferior aspect (viewed from below). The superior cerebellar artery supplies deep parts and superior parts of the cerebellum.
