Cerebrospinal fluid fills the space between
the arachnoid and pia mater of the central nervous system (CNS)
the ventricles of the brain
the central canal of the spinal cord
All of the above
Cerebrospinal Fluid:
The cerebrospinal fluid (CSF) is a clear watery nutritional fluid containing sodium chloride, potassium, glucose, and various proteins.
It fills the space between the arachnoid and pia mater of the central nervous system (CNS), the ventricles of the brain and the central canal of the spinal cord.
It is secreted by the choroid plexuses.
In addition to providing nutritional supply to the brain, the CSF also removes by-products of metabolism and also serves to provide a fluid cushion to protect the brain from injury
Hence, the correct answer is option d.
