What is the difference between backbone and spinal cord?​

“Backbone” isn’t really a medical term but refers to the bony structures or vertebral column, which surrounds the spinal cord. The vertebral column is made of the individual vertebrae - 7 cervical, 12 thoracic and 5 lumbar + sacral. The spinal cord runs in a central canal within the vertebral column, so is protected by the bony structures of the vertebrae.
