- A. It cushions the brain
- B. It protects the central nervous system
- C. It increases pressure at the base of the brain
- D. It fills the subarachnoid space
Explanation
Cerebrospinal fluid (CSF) is a clear, colorless fluid that circulates in the brain and spinal cord, acting as a cushion and protecting them from injury. It also delivers nutrients and removes waste products from the central nervous system. CSF decreases pressure at the base of the brain.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
