The most posterior of the three principal regions of the brain. 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]. [ http://zfin.org/curator http://en.wikipedia.org/wiki/Rhombencephalon ZFA : 0000029 ]

homology notes
  • Fine structural, computerized three-dimensional (3D) mapping of cell connectivity in the amphioxus nervous system and comparative molecular genetic studies of amphioxus and tunicates have provided recent insights into the phylogenetic origin of the vertebrate nervous system. 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]
