Which brain structures are derived from the metencephalon?

Which brain structures are derived from the metencephalon?

• A. Pons and Cerebellum
• B. Cerebrum
• C. Medulla
• D. Thalamus

Answer: (A)

During early brain development, the hindbrain (rhombencephalon) splits into two parts: the metencephalon and the myelencephalon. The metencephalon gives rise to the pons and the cerebellum, which together handle important relay and coordination functions between cortex and motor systems. The medulla oblongata comes from the neighboring myelencephalon, not the metencephalon, and the cerebrum and thalamus arise from the forebrain (prosencephalon). So the structures derived from the metencephalon are the pons and cerebellum.
