Herniated Disc C6-C7 Defined. C6/C7 is the last intervertebral disc fully contained within the cervical spine. C6/C7 bears the brunt of the wear and tear from neck movement and athletic strain. The head is a large and heavy object on a rather thin pole of vertebral bones and even thinner spinal discs.erniated Disc C6-C7 Defined.
