1. the portion of the brain developed from the most caudal of the three primary brain vesicles of the early embryo, comprising the metencephalon and myelencephalon.
2. the most caudal of the three primary vesicles formed in embryonic development of the brain, which later divides into the metencephalon and the myelencephalon. Called also hindbrain.

The part of the embryonic brain from which the <SC>cerebellum<D> and the brainstem, with the nuclei of most of the cranial nerves, develop. Technically known as the rhombencephalon.

hindbrain

the part of the brain forming the medulla and cerebellum, derived embryologically from the rear third of the brain. see FOREBRAIN, MIDBRAIN.
