The spine is composed of 33 vertebrae connected to each other with disks, joints, and soft tissues.
The vertebral column maintains our upright standing posture, and supports the movement of forward, backward and side bending as well as rotations. Additionally, each vertebra has posterior bony elements to protect the spinal cord.
Nerves travel through the spinal cord and act like electric cables to deliver the signals from the brain to the body, arms and legs. Nerves are responsible for motor activities and sensation. They also carry signals for the bowel and bladder control.
