Vertebrae and Cervical Spinal Nerves. The cervical spine (sometimes abbreviated as c-spine in the medical world) begins at the base of the skull. Seven vertebrae make up the cervical spine with eight pairs of cervical nerves. The individual cervical vertebrae are abbreviated C1, C2, C3, C4, C5, C6, and C7. The cervical nerves are also abbreviated; they are C1 through C8.
