Which of the following is NOT a function of the CSF? a. nourishment of the brainb. protection from blowsc. initiation of some nerve impulsesd. reduction of brain weight

Answer: c. initiation of some nerve impulses

Explanation:

Cerebrospinal fluid is a clear, colorless fluid that can be found in the brain and spinal cord. It is secreted by meninges and choroid plexus. It is absorbed by the arachnoid granulations.

The primary function of the CSF is to act as a cushion to the brain within the skull to serve as a shock absorber and prevents the injury from the blow. It also circulates the chemicals and nutrients filtered from the nerves and also removes the waste from the brain produced by the cerebral metabolism hence reduces the wastes from the brain.

The cerebrospinal fluid does not function in the initiation of the nerve impulses.
