The formation of basilar artery and its significance
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2016, Vol 4, Issue 4
Abstract
Abstract: Vertebro-basilar artery supplies the 20% of the blood supply of the brain. The formation of basilar artery is unique in our body system; it forms the important part in the posterior circulation. The aim of the study is to observe and record the length, the angle of formation of basilar and diameter of vertebral artery and compare the results with significance in the course of basilar artery. The study was done in 50 adult cadaveric human brains from Department of Anatomy, Vinayaka Missions Medical College, and Karaikal. The length and angle was measured using Digital Vernier calipher and Goniometer. The normal level of formation is 62%, angle of formation is between 40° to 90°, and the unequal diameter of right and left vertebral artery was observed in 22 specimens. The difference in diameter is one of the main factors for the formation of bending in basilar artery. And, these variations in the curvature of basilar artery is very important for clinical investigation and surgery. Keywords: basilar artery, vertebral artery, length of basilar artery, angle of formation, diameter of vertebral artery
