PY - 2018 T2 - Rudolph's Pediatrics, 23e AB - Cerebral spinal fluid (CSF) is found within the brain’s ventricular system and around the brain and spinal cord. An adult produces approximately 500 mL of CSF per day at a rate of 0.5 mL/min, and it is replenished every 4 to 6 hours. An infant has a total CSF volume of approximately 50 mL. CSF is produced by the ependymal cells of the choroid plexus in the lateral ventricles. It flows from the lateral ventricles through the foramen of Monroe to the third ventricle, and from there flows through the cerebral or Sylvian aqueduct to the fourth ventricle. Then the CSF exits via the cisterna magna and the lateral cisterns to the subarachnoid space and the central canal of the spinal cord. From here, it travels cranially to surround the sulci of the cerebral cortex. CSF is resorbed by entering the dural venous sinuses via the arachnoid granulations or villi.
