What is a key function of the ventricular system?

• A. Regulates intracranial pressure and facilitates CSF production and circulation
• B. Processes visual information
• C. Stores cerebrospinal fluid for energy
• D. Controls voluntary movements

Answer: (A)

The ventricular system mainly handles production and circulation of cerebrospinal fluid to regulate intracranial pressure. The choroid plexus inside the ventricles makes CSF, which flows through the lateral ventricles, the third and fourth ventricles, and into the subarachnoid space, where it’s absorbed. This circulation cushions the brain, maintains a stable pressure environment, and helps clear metabolic waste. It isn’t where visual information is processed, CSF isn’t stored for energy, and voluntary movements are controlled by motor and frontal brain regions, not the ventricular system.
