PPT-Blood Supply To The Brain

Jake Turner Learning Objectives Understand the basic blood supply of the brain Understand how to localise blockages of arteries based on symptoms Understand how to work out which parts of the brain will be based on where a blockage is. Jeanette. J. Norden, Ph.D.. Professor Emerita. Vanderbilt University School of Medicine. STROKE. Stroke is the . 3. rd. leading cause of death . in the U.S., and the . leading cause of disability. The brain is . Arteries of the Brain. The . brain is supplied by the two internal carotid and the two vertebral arteries. The four arteries lie within the subarachnoid space, and their branches anastomose on the inferior surface of the brain to form the circle of Willis. Brain Stem. Oldest and smallest region.
