Basilar artery is formed by the fusion of right and left vertebral artery and terminates as right and left posterior cerebral artery. The aim of the study is to observe and record the length of the basilar artery from the level of formation to level of termination and the diameter of basilar artery at three different levels. The study was done in 50 adult human cadaveric brains from Department of Anatomy, Vinayaka Missions Medical College, and Karaikal. The length and diameter was measured using Digital Vernier calipher. The mean length is 30.98mm and the range is 21-45mm in our study. And the mean diameter at three different levels is 3.55mm. These variations in the length and diameter of basilar artery is of diagnostic importance for the neurosurgeons and radiologists for clinical investigation and surgery.
