Answer

The basilar artery is the most important artery in the posterior circulation. It is formed at the pontomedullary junction by the confluence of both vertebral arteries. It lies on the ventral surface of the pons and, throughout its course, gives off the median, paramedian, short, and long circumferential branches.
