(FRAME-INFO (STRING "Cerebral Ventricles, Summary. A schematic dorsal view diagram \(left\), and a ventral view of a computer reconstruction of the cerebral ventricles \(right\). The lateral ventricle communicates with the third ventricle through the interventricular foramen \(more like a channel\), and the third ventricle communicates with the fourth ventricle through the cerebral aqueduct. From the fourth ventricle, cerebrospinal fluid \(produced by the choroid plexus in regions of all four ventricles\) gains access to the subarachnoid space via three exit foramina; the two lateral exit foramina \(one on each side\), and the single median exit foramen \(midline\). See the lateral exit foramen in cross section in Frame 11 in the Cerebellum chapter. The positions of the interventricular foramina and the median exit foramen are readily appreciated in a midsagittal MRI scan such as in Frame 24 in the Development and Topography chapter."))
