Blood Supply to the Human Spinal Cord. I. Anatomy and Hemodynamics

Abstract

The arterial network that supplies the human spinal cord, which was once thought to be similar to that of the brain, is in fact much different and more extensive. In this article, the authors attempt to provide a comprehensive review of the literature regarding the anatomy and known hemodynamics of the blood supply to the human spinal cord. Additionally, as the medical literature often fails to provide accurate terminology for the arteries that supply the cord, the authors attempt to categorize and clarify this nomenclature. A complete understanding of the morphology of the arterial blood supply to the human spinal cord is important to anatomists and clinicians alike.
