CSF
CSF: Cerebrospinal Fluid production and reabsorption
Produced in the choroid plexus of the lateral ventricles of the cerebrum, this fluid surrounds and nourishes the gray and white matter of the brain, as well as that of the spinal cord.
Reabsorption occurs via the subarachnoid lymphatic system (and potentially not the arachnoid villi as previously thought); primarily in the area of the cribiform plate (at the floor of the cranium, just above the nose). This has been shown recently by Johnston, Toronto Canada.
The CSF and therefore the intra-cerebral vaults, can be accessed via the cauda equina levels of the lumbar spine (lumbar puncture). Complications such as Hydrocephalus, can occur when the reabsorption or flow of CSF between the brain and the spinal cord is compromised.
