Background: The blood supply of the brain is quite important for understanding the process and effect of cerebrovascular accidents and other anomalies of brain function. Method: 30 (thirty) non-pathological cadaveric brains were studied for the metrical study of the basilar artery. The diameter and length were measured with a digital vernier calliper. Results: The mean length was 28.40 (± 4.48) and the range was 21.3–42.08. The mean diameter was 3.34 (± 0.68), and the range diameter was 2.06-4.48. Normal termination was 26 (86.6%), and variations were 4 (13.2%). Conclusion: It is concluded that the morphometric study of the basilar artery presents variations in the length, diameter, origin, and termination. These variations will be quite helpful for the neurologists, neurosurgeons, and radiologists for proper diagnosis and surgery to avoid morbidity and mortality in neuro-vascular accidents, anomalies, and pathologies of the brain.
