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

Please explain what cerebral spinal fluid (CSF) is, how it is made (structures involved); and discuss its complete circulation.
EXPLANATION ADDRESSING THE QUESTION ABOVE
Cerebral spinal fluid is a fluid that cushions the central nervous system and provides buoyancy to and helps nourish the brain. It circulates around the surface of the brain, interior ventricles, and surface of the spinal cord and central canal of the spinal cord. CSF is created by the ependymal cells in the choroid plexus and ventricles of the brain. CSF is made up mostly of water and also includes ions, nutrients like vitamin c and protein, and can pick up waste as it circulates. CSF circulation starts in the lateral ventricle where the choroid plexus and lateral ventricle creates or secretes the CSF. The CSF then flows through the ventricular foramen into the third ventricle. At the third ventricle, the CSF then flows through the cerebral aqueduct into the fourth ventricle. Then, the CSF exits the fourth…

You tell her the following: Cerebrospinal fluid (CSF) is formed as a filtrate of blood at the level of a choroid plexus. It passes through ependymal cells to the space between the arachnid mater and pia mater. Once it has traveled around the periphery of the brain within this space between those two meninges, the CSF then accumulates in the third ventricle. Once there, it passes to the fourth ventricle via the cerebral aqueduct and then travels via the central canal to the spinal cord. It is finally reabsorbed by the arachnoid granulations. The cerebrospinal fluid is turned over about three times every 24 hours. What error did you make in this description?
