Rhombencephalon

• the myelencephalon gives rise to the medulla oblongata
• The medulla oblongata has functions in vital function regulation like heartbeat and respiration
• The metencephalon gives rise to the pons and cerebellum
• The cerebellum controls posture, balance and the smooth execution of movements by coordinating sensory input with motor functions.
• The ependymal roof is a transparent roof that consists of a thin layer of ependymal cells that spans the fourth ventricle
• The choroid plexus forms in the ependymal roof of both metencephalon and myelencephalon
• The future site of the cerebellum is represented by so-called rhombic lips, at the border of the ependymal roof and the main body of the metencephalon
• The alar and basal plates become organized in columns of nuclei (aggregations of cell bodies in the brain). These contain visceral and somatic affetents (leading towards the brain) and efferents (leading away from the brain)
