Ventricular System

The ventricular system is the extension of the spinal canal (canalis centralis) into the brain and consists of four chambers which are filled with cerebrospinal fluid (liquor cerebrospinalis). The paired lateral ventricles (ventriculi laterales I and II) are two of these four chambers and are connected to the unpaired third and fourth ventricle through the foramen interventriculare. The following article gives an overview on the topography of the ventricles, their structure, as well as the production and re-absorption of liquor.
