Question 2

Discuss the location of cerebrospinal fluid (CSF) in relation to the basic functions of CSF; i.e., how does location facilitate function?

Accepted Answer

Cerebrospinal fluid completely surrounds the brain and spinal cord, in the subarachnoid space, acting as a shock absorber. Its location next to the pia mater in the subarachnoid space at the surface of the brain and spinal cord allow cerebrospinal fluid to influence and maintain ionic composition of fluid surrounding the central nervous system neurons. Cerebrospinal fluid can also deliver nutrients to and remove wastes from the central nervous system tissue as CSF flows throughout the ventricular system and is absorbed back into the bloodstream.
