Spinal cord Intervertebral disc Nucleus. The spinal cord is a long thin tubular structure made up of nervous tissue which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral columnIt encloses the central canal of the spinal cord which contains cerebrospinal fluidThe brain and spinal cord together make up the central nervous system CNS. These fibres coalesce to form the spinal part of the accessory nerve which then runs superiorly to enter the cranial cavity via the foramen.
