How is the back structured?

The spine, also called the backbone or spinal column, is one of the strongest parts of the body and gives us a great deal of flexibility and strength. It’s made up of 24 bones (vertebrae), one sitting on top of the other with discs in between and lots of strong ligaments and muscles around them for support.

On either side of the spine, running from top to bottom, are many small joints called the facet joints. The spinal cord passes inside the vertebrae, which protect it. Nerves pass through spaces between the bones of the spine to other parts of the body.

Structure of the head and neck

As you grow older, the structures of your spine, such as the joints, discs and ligaments, age as well. The structures remain strong but it’s usual for your back to get stiffer as you get older.
