Beginning with the production of CSF in the lateral ventricles and the eventual emptying of the CSF into the superior sagittal sinus, place the following statements in the correct sequence: - CSF enters the cerebral aqueduct. - The medial aperture and the two lateral apertures allow CSF to enter the subarachnoid space. - Circulating CSF moves into the superior sagittal sinus via arachnoid villi. - CSF moves into the third ventricle via the intraventricular foramen. - From the cerebral aqueduct, the CSF enters the fourth ventricle.

Plexus in the fourth ventricle adds more CSF. Subdural. Aqueduct. CSF fills the space and bathes external surfaces of the brain and spinal cord. Subarachnoid. CSF is secreted into each ventricle by the choroid plexus and flows into the third ventricle where more is added. Choroid. Lateral. At arachnoid villi, CSF is reabsorbed into venous blood of venous sinuses. Frontal. Posterior. CSF then flows down the cerebral aqueduct to the fourth ventricle. Dural. CSF then flows out two lateral apertures and one aperture. Median.

Name two functions of cerebrospinal fluid (CSF). Identify the components of the ventricular system and list the order of structures (page 339): Put the following events describing the flow of cerebrospinal fluid in order by writing the correct number (1-8) in the blank spaces: CSF enters the subarachnoid space. CSF travels down the cerebral aqueduct. CSF passes through the interventricular foramina (foramen = opening). CSF enters the fourth ventricle. CSF passes through the two lateral and one median apertures. CSF is released by ependymal cells. CSF enters the third ventricle. CSF is absorbed into the superior sagittal sinus by the arachnoid granulations.
