  1. What is cerebrospinal fluid (CSF)? Cerebrospinal fluid (CSF) is a clear or yellowish fluid that cushions the brain and spinal cord, removes waste, and circulates nutrients essential for brain function.
  2. Why is cerebrospinal fluid yellow? CSF can appear yellowish due to the presence of certain proteins and metabolic byproducts; however, it is typically clear under normal conditions.
  3. What functions does cerebrospinal fluid serve in the brain? CSF cushions the brain and spinal cord, protects the central nervous system, removes waste products, and helps maintain chemical balance and homeostasis.
  4. Where is cerebrospinal fluid produced? Cerebrospinal fluid is produced mainly by the choroid plexus in the brain's ventricles.
