metencephalon
http://purl.obolibrary.org/obo/UBERON_0001895

Rostral segment of the hindbrain that has as its parts the pons (where present) and the cerebellum[WP,modified].

the terms metencephalon and myelencephalon are only meaningful in mammals and birds[Neuroanatomy of the Zebrafish Brain]. 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 and thus these are not distinguished in ZFA[ZFA].

external_definition
  • Anterior part of the hindbrain ventral to the cerebellum[BIRNLEX:965].
  • The anterior of two brain vesicles formed by specialization of the rhombencephalon in the developing embryo. It gives rise to cerebellum and pons. [TFD][VHOG]

homology_notes

The early development of most vertebrate brains is similar (...). The zebrafish neural tube follows the same basic differentiation pattern as the mammalian neural tube (reference 1); The brain develops from three embryonic enlargements of the neural tube, which later differentiate into five regions. A forebrain differentiates into telencephalon and diencephalon. The midbrain, or mesencephalon, remains undivided. The hindbrain divides into the metencephalon and myelencephalon. Cavities within the brain enlarge to form a series of interconnected ventricles (reference 2).[well established][VHOG]
