The answer is symphysis joints. To simplify, vertebrae form symphysis joints connected by intervertebral discs. A symphysis or as called as the fibrocartilaginous joint is a joint in which the body of one bone come across the body of another. Completely but two of the symphyses lies in the vertebral or spinal column and all but one comprise fibrocartilage as an essential tissue. The momentary joint among the two halves of the jawbone is named the symphysis menti and is the only symphysis lacking fibrocartilage. All of the other symphyses are stable.
