spinal cord
Vertebral nerve bundle
The spinal cord is the bundle of nerve tissue that runs from the brain down through the vertebral column, carrying signals between the brain and the rest of the body.
Injury to the spinal cord can cause paralysis below the point of damage.
The accident severed his spinal cord.
Figuratively, the spinal cord of something is its essential conduit or backbone.
