Subarachnoid space, anesthetic needle

The subarachnoid space is a space in the spine,

Between the arachnoid membrane and pia mater of the spinal cord, the loin is the widest, containing cerebrospinal fluid and communicating with the ventricles. Adult spinal cord terminates to the lower edge of the first lumbar vertebrae. Lumbar puncture is generally performed between the 3rd and 4th lumbar vertebrae or the 2nd and 3rd lumbar vertebrae, where the cauda equina nerve is in the subarachnoid space, because it is very thin like the cauda equina, and it is floating in the cerebrospinal fluid. The possibility of nerve injury due to some puncture needles is very small. It's a safe place for a waist piercing. The subarachnoid spinal and cauda equina nerves both run up and down, parallel to the spine.
