Spinal Cord Injury
The spinal column is made up of 33 vertebrae that provide support for your body, allowing you to stand upright, bend, and twist, while protecting the spinal cord from injury.
Spinal cord nerves move from the the brain down the back. Made up of 31 pairs of nerves that leave the spinal cord and go to your arms, legs, chest and abdomen. These nerves allow send a signal to your brain to command your muscles to move your arms and legs.
These nerves control your arms and legs in the lower portion of the spinal cord. The nerves also control your heart, lungs, bowels, and bladder. Your spinal cord nerves can control how the speed of your heart beat and your rate of breathing.
This Spinal Canal is surrounded by the neck and back bones called vertebrae. The vertebrae ( that make up your back bones) are divided into 7 neck (cervical) vertebrae, 12 chest (thoracic) vertebrae and 5 lower back (lumbar) vertebrae. The vertebrae help protect the spinal cord from injury.
