The cerebral aqueduct (of Sylvius) connects the third ventricle to which ventricle?

Explanation:
The primary idea here is how CSF travels through the brain’s ventricular system. The cerebral aqueduct is the narrow passage that runs through the midbrain and connects the third ventricle above with the fourth ventricle below, allowing CSF to flow from the diencephalic region into the brainstem area. So the ventricle it connects to is the fourth ventricle. The lateral ventricles connect to the third ventricle via the foramen of Monro, and the third ventricle itself is the space that feeds the aqueduct, not the destination.
