Final answer:
The hindbrain does not mature into the metencephalon and myelencephalon.
Step-by-step explanation:
The hindbrain, which is the primary vesicle, does not mature into the metencephalon and myelencephalon (secondary vesicles). This statement is False. The hindbrain actually develops into the pons, cerebellum, and medulla. The metencephalon and myelencephalon are derived from the secondary vesicles.
