You have 33 bones in you body. These bones make up you spine.  These bones are stacked on top of each other with spongy cartilage between your bones.  The smallest vertebrae are the 7 in your back.  These 7 bones in your back support your neck.  They allow you to move your neck.  The next 12 vertebrae are attached to part of your ribs.  The next 5 vertebrae are the largest vertebrae.  The next 4 are your coccyx.  Your coccyx is your tailbone.  Many people have infuriated their spine.  If you damaged one of your vertebrae and you have pain you have a slipped disk.  Slipped disk means you have damaged one of your vertebrae.
