What is the function of the Cerebrospinal Fluid (CSF) in the brain?
What is the function of the Cerebrospinal Fluid (CSF) in the brain?
- Regulates the composition of the brain's extracellular fluid (ECF)
- Conditions the extracellular fluid (ECF) through glial cells
- Fills ventricles and forms a thin layer around the brain and spinal cord (correct)
- Protects the brain from fluctuations in blood composition
