Answer 1

Cerebrospinal Fluid

Produced by the choroid plexuses of the brain, the cerebral spinal fluid is contained in the subarachnoid cavity and spinal canal. It is reabsorbed by the arachnoid granulations.
Besides acting as a cushion for the CNS, the cerebral spinal fluid plays a critical part in the immunology of the central nervous system, blood flow in the CNS and autoregulation.
