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] MA:0000195 MAT:0000107 MBA:1065 MESH:D012249 MIAA:0000107 Posterior part of the brain consisting of the cerebellum and medulla oblongata.[AAO] TAO:0000029 The most posterior of the three principal regions of the brain, forming the rhombencephalon and all or most of the metencephalon. Kimmel et al, 1995.[TAO] 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].
