spinal cord
A lumbar puncture is usually done between the third and fourth lumbar vertebrae (L3 and L4) as, in adults, the thick part of the spinal cord has ended by this point, meaning it can't be damaged by the lumbar puncture. The nerve fibres in this area are called the cauda equina (horse's tail) and they actually seem to move out of the way as the needle passes though into the cerebrospinal fluid.
Cerebrospinal fluid is obtained by lumbar puncture.
A lumbar puncture takes about 30 minutes.
A lumbar puncture is typically performed in the lower back, between the third and fourth or fourth and fifth lumbar vertebrae. This location allows for the needle to be inserted into the subarachnoid space to collect cerebrospinal fluid for diagnostic purposes.
A lumbar puncture is generally performed in the lower back, between the third and fourth or fourth and fifth lumbar vertebrae. This location allows easier access to the cerebrospinal fluid in the subarachnoid space without risk of damaging the spinal cord.
