<prompt> Ventricles of brain are lined by ?EpendymocytesAstrocytesOligodendrocytesPodocytes  <response>: Ventricles of brain are lined by ependyma ependymocytes.Ventricles of brainThese are cavities in the brain lined by ependyma and filled with CSF.They contain choroid plexuses wich secrete CSF.These are four fluid filled intercommunicating cavities within the brain :-i Two lateral ventricles right and left,ii Third ventricle, andiii Fouh ventricle. o Lateral ventricle communicates with third ventricle by interventricular foramen foramen of Monro.Third ventricle communicates with fouh ventricle by cerebral aqueduct aqueduct of sylvius.Fouh ventricle communicates with subarachnoid space by a median foramen Mangendie and two lateral Luschka foramina.
