Subarachnoid cisterns

Dr Henry Knipe and Dr Jeremy Jones et al.

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. Cisterns may have vessels and/or cranial nerves passing through them.
