Describe in one paragraph the process of CSF production and intracranial pressure regulation. (Explain in your own words)
CSF is an extracellular fluid that is present inside the ventricles of the brain, subarachnoid space, and the central canal of the spinal cord. CSF is formed by the choroid plexus of lateral 3rd ventricles. Choroid plexus is a finger-like projection that is present on the floor of the ventricles of the brain. It is formed by the process of filtration and secretion. The plasma in the blood is passively filtered into the choroidal capillary endothelium of the choroid plexus by the ependymal cells. After this, there is a leads to the secretion of water and ions from the choroidal capillary endothelium. The secretion of the fluid is base on the active Na+ transportation to the cell. In this ATP or energy are used, 3 Na+ goes outside the blood capillaries and 2 ions of K+ goes inside the blood capillaries leads to formation of the CSF and lastly transported to the ventricles. Around 20 ml of CSF are produce every hourly in our body and 500 ml/day.
