Quizplus · Accepted Answer

The aqueduct of midbrain connects the third and fourth ventricles of the brain. In hydrocephalus, if the CSF cannot pass through this aqueduct, it can cause enlargement of the third and lateral ventricles, resulting in hydrocephalus. The other passages mentioned in the options are not directly related to the flow of CSF between these two ventricles.
