5
During the early development what are different structures of the fetal brain?
1) Prosencephalon
2) Mesencephalon
3) Rhombencephalon
During the later development what are the different structures of the fetal brain?

2) Diencephalon
3) Mesencephalon
4) Metencephalon
5) Myelencephalon
1) Prosencephalon –> –>
2) Prosencephalon–>–>
