Cerebrospinal fluid is a clear, colorless fluid produced by the choroid plexus in the interior of the brain. It consists of 99% water and 1% other substances. Cerebrospinal fluid covers the outside of the brain and spinal cord tissue to protect the brain and spinal cord from shock. Cerebrospinal fluid circulates in the subarachnoid space, is produced by the choroid, is absorbed by the arachnoid, and always maintains a dynamic balance between production and absorption. Choroid can produce 500 ml of cerebrospinal fluid every day, so the lumbar puncture to absorb l ~ 2 ml, no impact on the human body, will not leave any sequelae. In contrast, a necessary lumbar puncture allows for early diagnosis and timely treatment of the disease. Direct injection of drugs by lumbar puncture can also be used to treat diseases.
