AN ANATOMICAL STUDY OF CIRCLE OF WILLIS AND ITS VARIATIONS IN HUMAN CADAVERS - A SHORT REVIEW.
Journal Title: PARIPEX-Indian Journal of Research - Year 2017, Vol 6, Issue 11
Abstract
The blood supply of the central nervous system is of great importance because of the metabolic demands of the nervous system.Major part of the brain is supplied by the branches of two vertebral arteries and two internal carotid arteries.A significant anastomosis, the circle of willis exist between the vertebral and carotid arterial systems.The classical form of circle of willis is complete, of symmetrical normal calibre and polygonal in shape.Anatomic variations in the formation of circle of willis are studied by many scientists.The posterior part of the circle is more anomalous than anterior part and the posterior communicating artery is the most anomalous segment when compared to all the segments of the circle.Various diseases of carotid and vertebral arterial systems like stroke, hemorrhage, aneurysm, etc. are directly or indirectly related to the anatomic patterns of the circle of willis.
