Discuss the production, flow, and function of the cerebrospinal fluid (CSF).


Expert Answer

Step 1

Cerebrospinal fluid (CSF) is a clear, colorless liquid similar to blood plasma that circulates in the regions of ventricles and subarachnoid space of Central Nervous System. The exposed surfaces and the internal cavities of the central nervous system are bathed by the CSF.

Step 2

Production of CSF:

Cerebrospinal fluid is formed by the choroid plexus in each ventricle of the brain. The choroid plexus produces CSF at a rate of about 500mL per day. The choroid plexus is a network of capillaries and ependymal cells that lie within the pia mater.

CSF is originally formed from blood plasma which is filtered from capillaries, and then this fluid is further modified by the ependymal cells.  Thus, CSF is slightly similar to blood plasma. However, these two fluids differ by certain ion concentrations.

Step 3

Flow of CSF:

The CSF flows through and leaves the four brain ventricles and enters the subarachnoid space. In this region, the total volume of CSF ranges between 100mL and 160mL. This means that an excess amount of CSF is continuously eliminated from the subarachnoid space so that the fluid will not accumulate and damage the...
