What Secondary Brain Vesicles Form from the Forebrain

Question

What secondary brain vesicles form from the forebrain?
A)telencephalon and metencephalon
B)diencephalon and telencephalon
C)metencephalon and mesencephalon
D)metencephalon and myelencephalon

Accepted Answer

The forebrain forms the prosencephalon, which further divides into the diencephalon (which includes the thalamus and hypothalamus) and the telencephalon (which includes the cerebral cortex, basal ganglia, and olfactory bulbs). Therefore, the correct secondary brain vesicles formed from the forebrain are the diencephalon and telencephalon.
