How many ventricles are described in the ventricular system?

Explanation:
The ventricular system consists of four interconnected brain cavities that produce and circulate CSF. There are two lateral ventricles, one in each hemisphere, a single third ventricle in the diencephalon, and a single fourth ventricle between the brainstem and cerebellum. The lateral ventricles connect to the third via the foramen of Monro, the third connects to the fourth through the cerebral aqueduct, and the fourth opens into the subarachnoid space. Counting these chambers gives four ventricles in total. Four is the correct number.
