Anatomical terms of neuroanatomy

The hindbrain, rhombencephalon or lower brain

vertebrates. It includes the medulla, pons, and cerebellum. Together they support vital bodily processes.[2]

Metencephalon

Rhombomeres Rh3-Rh1 form the metencephalon.

The metencephalon is composed of the pons and the cerebellum; it contains:

Myelencephalon

Rhombomeres Rh8-Rh4 form the myelencephalon.

The myelencephalon forms the medulla oblongata in the adult brain; it contains:

Evolution

The hindbrain is homologous to a part of the

arthropod brain known as the sub-oesophageal ganglion, in terms of the genes that it expresses and its position in between the brain and the nerve cord.[3] It has been suggested that the hindbrain first evolved in the urbilaterian—the last common ancestor of chordates and arthropods—between 570 and 555 million years ago.[3][4]
