Obstruction to the flow of CSF at the aqueduct of Sylvius will most likely lead to enlargement of
CSF formation - choroid plexuses of the lateral third, and fouh ventricles. Some also originate from the ependymal cells lining the ventricles and from the brain substance CSF Circulation - lateral ventricles - third Ventricle of Sylvius - IV ventricle of magendie and Luschka - subarachnoid space - absorption by arachnoid vill Therefore, obstruction at aqueduct of sylvius will lead to enlargement of both lateral and third ventricles.
All of the ventricales
Only lateral ventrical
Only fouh ventrical
Both lateral and third ventricles
