Flow of cerebrospinal fluid (CSF)

Having trouble visualizing the ventricles and canals that contain CSF (cerebrospinal fluid)?   Or the pathway of circulation of the CSF?

Here's a brief animated video that walks you through it all in a simple, straightforward way.

The video uses eponyms and other terminology you may not be using in your course, so here are some translations:
  • ependymal cavity = ventricle
  • foramina of Munro = interventricular foramina
  • aqueduct of Sylvius = cerebral aqueduct (aqueduct of midbrain)
  • foramen of Magendie = median foramen or median aperture (of fourth ventricle)
  • granulations of Pacchioni = arachnoid villi or arachnoid granulations

Click on the image above for a freaky animated MRI (magnetic resonance image) showing the pulsing of the CSF with the hearbeat in aa person with normal pressure hydrocephalus (NPH). Image (c) Nevit Dilmen.
