In mammals and birds the hindbrain is divided into a rostral metencephalon and a caudal myelencephalon. In zebrafish, with the exception of the cerebellum, the ventral remainder of the metencephalon can be separated only arbitrarily from the more caudal myelencephalic portion of the medulla oblongata (From: Neuroanatomy of the Zebrafish Brain)[ZFA]. Organ component of neuraxis that has as its parts the pons, cerebellum and medulla oblongata[FMA]. in MA, brainstem and hindbrain and part-of siblings under brain, consistent with FMA and NIF.

The results suggest that several of the genetic mechanisms for establishing and patterning the vertebrate nervous system already operated in the ancestral chordate and that the nerve cord of the proximate invertebrate ancestor of the vertebrates included a diencephalon, midbrain, hindbrain, and spinal cord.[well established][VHOG] EHDAA:6487 The most posterior of the three principal regions of the brain, forming the rhombencephalon and all or most of the metencephalon.
