rhombencephalon

 [rom″ben-sef´ah-lon]
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.

rhom·ben·ceph·a·lon

(rom'ben-sef'ă-lon), [TA]
That part of the developing brain that is the most caudal of the three primary vesicles of the embryonic neural tube; secondarily divided into metencephalon and myelencephalon; the rhombencephalon includes the pons, cerebellum, and medulla oblongata.

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.

This type of radial migration is mostly performed by neurons that have executed tangential migration underneath the pial surface and includes granule cells of the cerebellum (6) and neurons of the pontine nuclei (PN) in the hindbrain. (7) After leaving their site of generation, these neurons migrate circumferentially beneath the pial surface and then leave there by initiating radial migration away from the pia (Fig.

The molecular genetic theory postulates that Chiari malformations result from primary defects in the genetic programming of hindbrain segmentation and of growth of associated bone and cranial structures.2 The hydrodynamic pulsion theory suggests that early progressive foetal hydrocephalus pushes down on the brainstem and cerebellum.3 And the oligocerebrospinal fluid theory proposes that defective closure of the neural tube in early foetal development results in leakage of cerebrospinal fluid, and thus insufficient cerebrospinal volume to fully distend the embryonic ventricular system, which leads to a small posterior fossa and cerebral disorganization.4
Evolution has gifted us with three aspects to the brain: the lizard brain (ancient hindbrain) focuses on survival, the monkey brain (limbic system) deals with emotions and social behavior, and the human brain (neocortex) controls rational decision-making.
