csf is formed by specialized ependymal cells and capillaries called
Ependyma Lining the CSF-filled ventricles, the ependymal cells play an important role in the production and regulation of CSF. Their apical surfaces are covered in a layer of cilia, which circulate CSF around the CNS. Their apical surfaces are also covered with microvilli, which absorb CSF. Within the ventricles of the brain, a population of modified ependymal cells and capillaries together known as the tela choroidea form a structure called the choroid plexus, which produces the CSF.[3]
Swallowing 5) Closure of the nasopharynx
Cerebrum With the assistance of the cerebellum, the cerebrum controls all voluntary actions in the body.
Neuroglia Microglia are specialized macrophages capable of phagocytosis that protect neurons of the central nervous system.[17] They are derived from the earliest wave of mononuclear cells that originate in yolk sac blood islands early in development, and colonize the brain shortly after the neural precursors begin to differentiate.[18]
