Anatomy study note · Head and neck

Ventricles of the brain

The cavities of the brain, filled with cerebrospinal fluid made by their choroid plexuses: two lateral ventricles, the third ventricle and the fourth ventricle.

Key points

• Lateral → interventricular foramen → third → aqueduct → fourth → central canal / subarachnoid space.
• CSF from the choroid plexuses.
• Lateral ventricle horns: anterior, posterior, inferior.
• Choroid plexus (ependyma) makes CSF.
• Arachnoid granulations reabsorb it.
