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…
