Subarachnoid space, anesthesia

The subarachnoid space is a space in the spine,

Between the arachnoid and pia mater of the spinal cord, the waist is the widest, contains cerebrospinal fluid, and communicates with the ventricle. In adults, the spinal cord stops to the lower edge of the first lumbar vertebrae. Lumbar puncture is usually performed between the 3rd to 4th or 2nd to 3rd lumbar vertebrae. Here is the cauda equina nerve in the subarachnoid space, because it is very thin like a cauda equina and floats. In the cerebrospinal fluid, the possibility of nerve damage due to some puncture needles is very small. It is a safe part for waist wear. Both the spinal nerve and cauda equina in the subarachnoid space run up and down, parallel to the spine.
