The hindbrain, rhombencephalon (shaped like a rhombus) is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum . Together they support vital bodily processes.
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
The cerebellum (pl.: cerebella or cerebellums; Latin for "little brain") is a major feature of the hindbrain of all vertebrates.Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as it or even larger. [1]
The hindbrain coordinates and integrates sensory and motor inputs and outputs responsible for, but not limited to, walking, swimming, or flying. It contains input and output axons interconnecting the spinal cord, midbrain and forebrain transmitting information from the external and internal environments. [ 59 ]
The brainstem has integrative functions being involved in cardiovascular system control, respiratory control, pain sensitivity control, alertness, awareness, and consciousness. Thus, brainstem damage is a very serious and often life-threatening problem.
Initially there are three primary brain vesicles: prosencephalon (i.e. forebrain), mesencephalon (i.e. midbrain) and rhombencephalon (i.e. hindbrain). These develop into five secondary brain vesicles – the prosencephalon is subdivided into the telencephalon and diencephalon, and the rhombencephalon into the metencephalon and myelencephalon.
Mutations in the Gli2 protein causes more severe damage in the ventral patterning of the hindbrain than that of the spinal cord. This shows that Gli2 performs different functions in the hindbrain that Gli3 is unable to substitute. Gli2 and Gli3 in a developing hindbrain also have distinct functions in the Shh (sonic hedgehog) signal transduction.
During fetal development, divisions of the neural tube that give rise to the hindbrain (rhombencephalon) and the other primary vesicles (forebrain and midbrain) occur at 28 days after conception. With the exception of the midbrain, these primary vesicles undergo further differentiation at 5 weeks after conception to form the myelencephalon and ...
