What are the fluid filled spaces of the brain called? Write few lines about its position.

Explanation

Ventricles of the brain: The brain has four hollow, fluid filled spaces. The C-shaped space found inside each cerebral hemisphere forms the lateral ventricles I and II which are separated from each other by a thin membrane called the septum pellucidum. Each lateral ventricle communicates with the narrow III ventricle in the diencephalon through an opening called interventricular foramen (foramen of Monro). The ventricle III is continuous with the ventricle IV in the hind brain through a canal called aqueduct of Sylvius.
