Practice Question # 1014.

Cerebrospinal Fluid:

CSF, a clear and colorless fluid with a specific gravity of 1.007, is produced in the ventricles and is circulated around the brain and the spinal cord through the ventricular system. There are four ventricles: the right and left lateral, and the third and fourth ventricles.

The two lateral ventricles open into the third ventricle at the interventricular foramen or the foramen of Monro. The third and fourth ventricles connect via the aqueduct of Sylvius. The fourth ventricle supplies CSF to the subarachnoid space and down the spinal cord on the dorsal surface. CSF is returned to the brain and is then circulated around the brain, where it is absorbed by the arachnoid villi.

CSF is produced in the choroid plexus of the lateral, third, and fourth ventricles. The ventricular and subarachnoid system contains approximately 125 to 150 mL of fluid, while 15 to 25 mL of CSF is located in each lateral ventricle.
