"The metencephalon goes on to form the pons, the majority of the cerebellum and the fourth ventricle. The myelencephalon becomes the medulla oblongata, and the central canal 1. The most rostral portion of the cerebellum receives contributions from the mesencephalon, and the floor of the fourth ventricle is derived in part, from the myelencephalon."
"The embryonic/fetal rhombencephalon is visible with endovaginal ultrasound at ~8-10 weeks as a hypoechoic region in the posterior embryonic/fetal head. Strictly speaking, this is the rhomboid fossa, part of the rhombencephalon complex rather than the rhombencephalon itself 5. The hypoechoic region represents the developing rhombencephalon/hindbrain (medulla, pons, and cerebellum)."
