These four models are sections of the lower back region of the spine. Each model consists of two vertebrae, with a disc in between. The yellow structures that exit between each one of the vertebrae is called the spinal nerve root. These nerve roots connect to organs, tissues, muscles, and glands all throughout your body! As you can see, the model on the far left looks different than the one on the far right. These models demonstrate how the spine breaks down when subluxation is left undetected and uncorrected!
