Explanation
Spinal describes the area of the backbone. Your spinal cord, which is protected by the vertebrae of the backbone, connects the brain and the body. A spinal injury is serious because it affects the body’s ability to move and function. The adjective spinal comes up often in medicine. Spinal fluid acts as a cushion for your brain and spine; a spinal tap is a special kind of test for evaluating this fluid. Doctors and nurses often refer to anesthesia that's injected into the spine simply as a spinal. The adjective has been around since the 16th century, from the Late Latin spinalis. "pertaining to a thorn or the spine."
