Studying embryology at medical school may at times feel like a waste of time. Neuroanatomy is complicated though and I think understanding how the brain forms makes learning neuroanatomy a lot easier.
Three primary vesicles form at the rostral end of the neural tube: - Prosencephalon - Mesencephalon - Rhombencephalon
The prosencephalon goes on to form two secondary vesicles - the telencephalon and the diencephalon. A further two vesicles form from the rhombencephalon - the metencephalon and myelencephalon.
