ANATOMY - The Back
Low Back Anatomy
Your spine moves thousands of times each day in an infinite combination of directions. Thus, it is no surprise that almost everyone will experience some sort of back pain at onetime in their lifetime. To fully understand how to recover from your back pain, you should have some background in anatomy. This section will give you a better understanding of the anatomy of your lower back.
The human spine (backbone) is composed of small bones called vertebrae. The vertebrae are stacked one on top of another to form a column called the spinal column. In between each of these vertebrae there are cushions called disks to help absorb the shock your low back takes each day. In addition, these disks allow your spine to move in a multitude of directions not possible with a standard ball and socket type joint.
Your spinal cord runs through the back half of your spinal column using the tough bony covering to protect itself against injury. The spinal cord gives off branches all the way down its path through your spinal column. These branches are called nerve roots just like a tree gives off roots. The roots exit the spinal column through specially designed holes called neural foramina (a big word for nerve exit).
