Which cells produce and circulate CSF?

Explanation:
Ependymal cells line the brain’s ventricular system and form the choroid plexus, where cerebrospinal fluid is produced. They actively secrete CSF, and their cilia help move it through the ventricles so it circulates around the brain and spinal cord. This system ultimately channels CSF into the subarachnoid space and is then absorbed into the venous system. Astrocytes support neurons and help maintain the blood-brain barrier, but they do not produce CSF. Microglia are immune cells in the CNS, not CSF producers or movers. Neurons are signaling cells and do not secrete CSF either.
