Answer:
Cerebrospinal fluid circulates within the ventricles of the brain and in the subarachnoid space is called Cerebrospinal fluid circulation
Explanation:
CSF is formed within the ventricles by small, delicate tufts of specialized tissue called the choroid plexus
the major pathway of CSF flow. Beginning in the lateral ventricles, CSF flows through two passageways into the third ventricle. From the third ventricle it flows down a long, narrow passageway (the aqueduct of Sylvius) into the fourth ventricle. From the fourth ventricle it passes through three small openings (foramina) into the subarachnoid space surrounding the brain and spinal cord
