Articular processes

Overview
The articular processes (zygapophyses) of a vertebra, two superior and two inferior, spring from the junctions of the pedicles and laminæ.


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

The articular surfaces are coated with hyaline cartilage.
