The metencephalon develops into which two structures?

The metencephalon develops into which two structures?

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

Answer: (D)

In brain development, the hindbrain (rhombencephalon) splits into two parts: the metencephalon and the myelencephalon. The metencephalon becomes two structures—the pons and the cerebellum. The pons serves as a major relay between the cortex and the cerebellum and other brain regions, while the cerebellum coordinates balance and smooth, coordinated movements. The medulla comes from the myelencephalon, not the metencephalon, and the thalamus comes from the diencephalon (part of the forebrain), so the two structures derived specifically from the metencephalon are the pons and the cerebellum.
