Â© Reed Group. Degeneration of cervical intervertebral discs is common, and often postulated as a cause of neck and arm pain. The neck (cervical spine) is made up of seven vertebrae. Starting with cervical vertebra number 2 (C2), an intervertebral disc separates each vertebra from the vertebrae below. A cervical intervertebral disc is a spongy structure that helps absorbs shock and allows movement of the cervical vertebrae. A degenerating disc loses some of its thickness and becomes less flexible, causing the space between two vertebrae to narrow.
