Rhombencephalon

The hindbrain (Greek for " hindbrain " ) is part of the central nervous system and is the part of the brain adjacent to the spinal cord.

It consists of

• Metencephalon ( hindbrain ) with cerebellum ( cerebellum) and pons (bridge)
• Myelencephalon ( hindbrain, medulla oblongata )

The cerebellum sits the remaining shares of the hindbrain to move forward and, together with the cerebellum Sailing the roof of the fourth ventricle ( ventriculus quartus ). The floor of the fourth ventricle is formed by the pons and the medulla oblongata and, with its diamond-shaped base name-giving, both for the so-called rhomboid fossa ( fossa rhomboidea ) as well as for the entire brain section.

The affinities of the various units of the hindbrain is explained by the embryonic development of the brain. This phenomenon in the brain occurs later than vesicular structures at the anterior end of the neural tube for the first time. Due to the different growth of various sections a three bubble structures developed in the further course. For the rear bubbles all subsequent portions of the hindbrain develop. From the first blisters the later sections of the brain arise front and mid-brain, from the middle later midbrain.
