Explanation
Cerebrospinal fluid (CSF) is a clear, colorless liquid that fills and surrounds the brain and the spinal cord and provides a mechanical barrier against shock. It occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord. 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.

About Brain
The brain includes the cerebrum, cerebellum, brainstem, hypothalamus and medulla, each with distinct roles in sensation, movement and homeostasis. Questions connect major brain regions with their functions, reflex control and coordination, while distinguishing involuntary responses from hormonal regulation.
