Background: The brain gets its blood supply from two sources, namely, internal carotid system and vertebrobasilar system of arteries. Right and left internal carotid arteries enter the carotid canal and reach the base of the brain. Here, they anastomose with vertebrobasilar system of arteries to form the circle of Willis. This study was conducted for morphological assessment of basilar artery and its variations in the local population. Materials and Methods:Forty cadavers—20 female as well as 20 males—were dissected. The typical dissection manual approach was used while removing the brains. The surplus preservatives were removed from the brains by giving them a thorough water wash. In order to avoid disturbing any blood vessels, the arachnoid mater was gently removed from the base of the brain. Results: Level of formation of basilar artery was at pontomedullary junction in 32 subjects. Level of formation of basilar artery was above and below pontomedullary junction was in 5 and 3 cases, respectively. Level of termination of basilar artery was at pontomesencephalic junction, above as well as below pontomesencephalic junction in 31, 5 and 4 cases, respectively. Conclusion: The basilar artery's length as well as diameter showed no gender propensity. Surgeons will benefit from the baseline data established in this study regarding the length, diameter, level of origin, and level of termination of the basilar artery.
