Cerebrospinal fluid is a colorless transparent fluid that fills the ventricular system, subarachnoid space, and central canal of the spinal cord, mainly created by the ventricular choroid plexus. The cerebrospinal fluid produced by the lateral ventricular choroid plexus flows into the third ventricle through the inter-ventricular orifice, flows into the fourth ventricle through the midbrain tube together with the cerebrospinal fluid produced by the third ventricular choroid plexus, then merges the cerebrospinal fluid produced by the fourth ventricular choroid plexus together into the subarachnoid space through the fourth ventricular median orifice and the two lateral orifices, and then the cerebrospinal fluid permeates into the superior sagittal sinus through the arachnoid particles and flows back into the venous system.
