III. CSF flow and hydrocephalus
CSF Flow:
CSF is produced by the choroid plexus within the lateral and fourth ventricles. Normally the pathway of flow is: lateral ventricles, foramen of Monro, third ventricle, aqueduct of Sylvius, fourth ventricle, foramina of Magendie and Luschka; subarachnoid space over brain and spinal cord; reabsorption into venous sinus blood via arachnoid granulations.
