which division of the ANS is also called the thoracolumbar division? Why?
What are the similarities and differences between SNS and ANS reflexes? Explain?
Peyton felt strange when she awoke one morning. She could not hold a pen in her right hand when trying to write an entry in her diary, and her muscles were noticeably weaker on the right side of her body. Additionally, her husband noticed that she was slurring her speech, so he took her to the emergency room. What does the ER physician suspect has occurred? Where in the brain might the physician suspect that abnormal activity or perhaps a lesion is located, and why?

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…arrow_forward
