Detailed Solution

The cerebrospinal fluid (CSF) is a clear, colorless fluid that surrounds and cushions the brain and spinal cord within the subarachnoid space, which is the space between the meninges (protective membranes) of the central nervous system. Its main function is to act as a protective barrier, absorbing and distributing shocks and impacts that may occur due to sudden movements or external forces.

The CSF helps prevent the brain from directly contacting the skull, reducing the risk of injury and providing a protective buffer against mechanical damage.

Additionally, the CSF also aids in the removal of waste products from the brain and supplies essential nutrients to brain cells.
