The ventricles are shown in blue on the following midsagittal section of the brain. The Ventricles CSF is produced mainly by a structure called the choroid plexus in the lateral, third and fourth ventricles.CSF flows from the lateral ventricle to the third ventricle through the interventricular foramen (also called the foramen of Monro).he third ventricle and fourth ventricle are connected to each other by the cerebral aqueduct (also called the Aqueduct of Sylvius). CSF then flows into the subarachnoid space through the foramina of Luschka (there are two of these) and the foramen of Magendie (only one of these).
Overview. The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the following images).he rest of the CSF production is the result of transependymal flow from the brain to the ventricles. CSF flows from the lateral ventricles, through the interventricular foramens, and into the third ventricle, cerebral aqueduct, and the fourth ventricle.
