Ventricles of the brain
Learning objectives
After going through this study unit, you should be able to:
- Explain what is the ventricular system of the brain and its function.
- Describe the structures that comprise the ventricular system of the brain.
Watch videos
The ventricles of the brain are an interconnected network of cavities filled with cerebrospinal fluid (CSF) located within the brain parenchyma. The ventricular system consists of the two lateral ventricles, the third ventricle, and the fourth ventricle. The choroid plexuses, located within each ventricle, produce CSF which fills the ventricles and subarachnoid space. This fluid cushions the brain and spinal cord from injury and also serves as a nutrient delivery and waste removal system for the brain.
