. It arises from the basilar artery on each side at the level of the junction between the medulla oblongata and the pons in the brainstemIt has a variable course passing backward to be distributed to the anterior part of the undersurface of the cerebellum.

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 Willis from the internal carotid arteries. In some people the symptoms of the stroke last for only a few seconds or minutes transient ischemic attack or mini-stroke while in others the symptoms of the stroke may be persistent.
