Lumbar Puncture

Explanation:

Lumbar puncture is a process usually used to collect cerebro-spinal fluid. This process is often used to detect diseases of the central nervous system. Sometimes it is also used to inject medication. Lumbar puncture takes place in the lower lumbar region of the spinal chord because spine contains the cerebrospinal fluid and it becomes safe to collect CSF from this region without any major side effects.

Answer: A lumbar puncture (spinal tap) is performed in your lower back, in the lumbar region. During a lumbar puncture, a needle is inserted between two lumbar bones (vertebrae) to remove a sample of cerebrospinal fluid. This is the fluid that surrounds your brain and spinal cord to protect them from injury.
