The arteries that join to form the basilar artery are part of which cerebral circulation?

Explanation:
The arteries that join to form the basilar artery are part of the posterior circulation. The basilar artery is created by the fusion of the two vertebral arteries, which come together to supply the brain via the vertebrobasilar (posterior) system. This circulation feeds the brainstem, cerebellum, and posterior regions of the cerebral hemispheres, in contrast to the anterior circulation, which comes from the internal carotid arteries and supplies the front of the brain. Venous circulation and external carotid arteries are not involved in forming the brain’s arterial supply.
