The articular processes or zygapophyses (Greek ζυγον = "yoke" (because it links two vertebrae) + απο = "away" + φυσις = "process") of a vertebra, two superior and two inferior, spring from the junctions of the pedicles and laminæ. These stick out of an end of a vertebra to lock with a zygapophysis on the next vertebra, to make the backbone more stable.

• The superior processes or prezygapophysis project upward from a lower vertebra, and their articular surfaces are directed more or less backward.
• The inferior processes or postzygapophysis project downward from a higher vertebra, and their articular surfaces are directed more or less forward and outward.
