The most caudal of the primary vesicles that are present in the early neural tube, which later gives rise to two secondary vesicles: metencephalon (prospective pons and cerebellum) and myelencephalon (prospective medulla oblongata).
(Greek rhombos = rhomboid, enkephalos = brain) hindbrain, at the early (3 primary vesicle) stage of brain development, this is the most caudal vesicle. At the 5 secondary vesicle stage of brain development this then forms both the metencephalon and the myeloncephalon. Finally forming the adult structures of cerebellum, pons and medulla. (More? Neural Notes)
the posterior portion of the brain including cerebellum and brainstem
Greek rhombos = rhomboid, and enkephalos = brain; hence, the hind-brain - the medulla oblongata, pons and cerebellum, which enclose the rhomboid fossa (the floor of the 4th ventricle).
The part of the brain developed from the posterior vesicle. It includes the metencephalon and the myeloncephalon, the cerebellum, pons and medulla.
rhombos (rhomboid or diamond shaped), enkephalos (brain).
(Gr. rhombos + enkephalos, brain): The hindbrain; most caudal of the three primary vesicles of the embryonic brain. The adult derivatives of which are the cerebellum and pons (metencephalon) and the medulla oblongata (myelencephal on).
The rhombencephalon (or hindbrain) is a developmental categorization of portions of the central nervous system in vertebrates.
