CSF chemistry
|
Cerebrospinal fluid (CSF) is a clear fluid that circulates in the space surrounding the spinal cord and brain. CSF protects the brain and spinal cord from injury by acting like a liquid cushion. CSF is usually obtained through a lumbar puncture (spinal tap). During the procedure, a needle is inserted usually between the 3rd and 4th lumbar vertebrae and the CSF fluid is collected for testing.

Lumbar vertebrae
|
There are 5 lumbar vertebrae located in the lower back. These vertebrae receive the most stress and are the weight-bearing portion of the back. The lumbar vertebrae allow movements such as flexion and extension and some lateral flexion.
