Cerebrospinal fluid (CSF) Cerebrospinal fluid (CSF), clear, colourless liquid that fills and surrounds the brain and the spinal cord and provides a mechanical barrier against shock. Formed primarily in the ventricles of the brain, the cerebrospinal fluid supports the brain and provides lubrication between surrounding bones and the brain and spinal cord. When an individual suffers a head injury, the fluid acts as a cushion, dulling the force by distributing its impact.
The more recently developed areas â the cerebellum and the cerebrum â surround the brain stem. The cerebellum is a cauliflower-shaped structure, located just above the brain stem, beneath the occipital lobes at the base of the skull.
