Chapter 13, Problem 7ILQ
Watch this animation (http://openstaxcollege.org/l/bloodflow1) to see how blood flows to the brain and passes through the circle ofWillis before being distributed through the cerebrum. The circle of Willis is a specialized arrangement of arteries that ensure constant perfusion of the cerebrum even in the event of a blockage of one of the arteries in the circle. The animation shows the normal direction of flow through the circle of Willis to the middle cerebral artery. Where would the blood come from if there were a blockage just posterior to the middle cerebral artery on the left?

Callisto survives the accident and goes to jail. Many years later she is found slumped in her cell, quite confused and with apparent paralysis in her right arm. When the jailer speaks to her, she is unable to produce any clear speech. Callisto can understand very simple sentences, and her sight is not affected. It is determined that she has a vascular occlusion (blockage) in her internal carotid artery. Callisto’s blood pressure is markedly lower than would be expected under physiological conditions.
Based on this information, how are these structures in brain affected (if they are). Provide justification. Short answers.
1. Broca's area
2. Right posterior cerebral artery
3. Autonomic nervous system
In planning treatment for a patient who has had a cerebrovascular accident (CVA), why would it be important to know whether the CVA was caused by a ruptured or obstructed blood vessel?
