The head of the rib articualtes with the superior coastal facet of the vertebra after which it is number, the i … nferior coastal facet of the vertebra above it and the articular facet on the transverce process of the vertebrae aftr which it is numbered.ach disc is slightly flexible, so the combined movement of many of the joints in the vertebral column allows the back to bend forward or the the side or to twist. they are amphiarthrotic joints because these joints allow slight movement.
