Imagine a railroad station with trains chugging in and out in every direction. What is the benefit of a nice railroad station that runs smoothly? All trains run on schedule and all the passengers are happy.
Your spinal cord is just like a railroad station. Instead of trains, however, nerves enter and exit the “station” at various points: the process is called innervation. They slide into the spinal cord by passing in between vertebrae. From the spinal cord, they travel to and from the body’s muscles, organs and other structures.
Each vertebra has its own set of nerves that weave in, out and around it. Dysfunction or injury of the vertebrae can short-circuit this intricate wiring system. Ongoing research indicates that vertebral subluxations may affect nerve transmission and the structures those nerves innervate.
