I saw on a science TV show that new discoveries are being made about the nerves to the backbone. What are some of these?
Scientists have found dense bundles of nerve tissue inside the bones of the spine (vertebrae). A group of nerves together is called a nerve plexus. Researchers think that the number and size of these plexus suggests many different functions. We know that nerves release a chemical called substance P. Substance P sends the brain pain signals. Other forms of sensation may be sent through this nerve plexus. It’s possible that the nerve plexus inside the vertebrae also controls bone growth and function. The blood supply to the bone may be under the control of these nerves as well. Finally, it may turn out that these nerves inside the bones of the spine cause back pain. If this is true, treating back pain may begin by altering the messages sent by the nerve plexus.
