What is contained within the ventricles of the brain?

• A. Cerebrospinal fluid (CSF)
• B. Blood
• C. Meninges
• D. Neural tissue

Answer: (A)

Ventricles are fluid-filled spaces inside the brain, and their main content is cerebrospinal fluid that cushions the brain, helps circulate nutrients, and removes waste. The CSF is produced by the choroid plexuses within the ventricles and fills these spaces as well as the surrounding subarachnoid space. Because of this, the ventricles contain CSF rather than blood, meninges, or neural tissue. Blood sits in brain vessels, meninges are the protective membranes around the brain, and neural tissue refers to the brain itself, not the fluid filling the ventricular cavities.
