Circulation of Cerebrospinal Fluid

This exhibit depicts a sagittal view of the brain with normal circulation of cerebrospinal fluid (CSF). Circulation begins with CSF production by modified ependymal cells in the choroid plexus, around blood vessels, and along ventricular walls. CSF then circulates into the lateral ventricles, third ventricle, fourth ventricle, median aperture, lateral apertures, into the subarachnoid space around the spinal cord and brain.
