During a procedure called a "lumbar puncture", CSF surrounding the meninges is withdrawn with a needle. This procedure generally is performed between L3 and L5. Why do you think the fluid is withdrawn here rather than from higher up in the vertebral column. Often, the sampled CSF is tested for bacteria or viruses if a brain infection is suspected. Why would CSF sampled from the spinal cord give you information about the condition of the brain?
