Describe the Production, flow and absorption of Cerebrospinal Fluid in the central nervous system.arrow_forwardA bit confused about this question I placed my answer below the question but not sure if the brain is synonymous or not with the peripheral nervous system due to the wording of the question. In the background section the authors wrote “Neurodegenerative disease are progressive conditions that occur through impairment in the function or structure of neurons in the peripheral nervous system or brain [1].’ Based on this quote, is the “or brain” statement synonymous with the peripheral nervous system or is the “or brain” statement in addition to the peripheral nervous system? The nerves outside of the brain and spinal cord are part of the peripheral nervous system. The main function of the peripheral nervous system is to transmit signals from the brain and spinal cord to the rest of the body making the "or brain" statement synonymous. How do you know that your answer to question 1 is correct?arrow_forwardReflexes can be somatic (as in the knee jerk response) or visceral (as in vomiting). Given that both result in an involuntary motor response, why aren’t they both considered visceral motor?arrow_forward
