Fouh ventricle develops from:
Telencephalon
Mesencephalon
Diencephalon
Rhombencephalon
Lateral ventricle develops from the cavity of telencephalon. Third ventricle develops from diencephalon. Cavity of mesencephalon remains narrow and forms the aqueduct, while the cavity of rhombencephalon forms the fouh ventricle.Ref: Human Embryology By Inderbir singh, 7th edition, Page 306
