What does the ambient cistern do?

What is basilar cistern?
The subarachnoid cisterns, or basal cisterns, are compartments within the subarachnoid space where the pia mater and arachnoid membrane are not in close approximation and cerebrospinal fluid (CSF) forms pools or cisterns (Latin: “box”). As they are interconnected, their patency is essential for CSF circulation.
Where is the quadrigeminal cistern located?
