Quizplus · Accepted Answer

CSF does not circulate through the corpus callosum, which is a large bundle of nerve fibers that connects the two hemispheres of the brain. CSF circulates through the ventricles and subarachnoid space, which surrounds and cushions the brain and spinal cord. Specifically, CSF flows from the lateral ventricles to the third ventricle via the interventricular foramina, then through the cerebral aqueduct to the fourth ventricle, and finally into the subarachnoid space via the median and lateral apertures.
