The bottom line is that YOU bear the responsibility for preventing back injury. The following tips can help you maintain a healthy back. Your back is composed of vertebrae, discs, nerves and muscles. Maintaining these natural curves keeps the spine in balance. Each disc contains a jelly-like center surrounded by rings of tough fibrous tissue.
Nerves are a collection of fibers which carry electrical impulses throughout the body.
The spinal cord stretches the length of the spine through the vertebral column. Smaller nerves branch out between each vertebrae to carry messages around the body. Ligaments are bands of fibrous tissue that connect bones or cartilage together - serving to support and strengthen joints. Tendons are fibrous cords of connective tissue which attach muscle to bone. Place one hand cupped under your chin, with the other in back of your head at the base of the skull.
