zygapophysialis
Zygapophysialis is an anatomical term used to designate features of the zygapophysial joints, or facet joints, of the vertebral column. Zygapophysial joints are synovial, planar joints that contribute to the articulation between adjacent vertebrae and help control spinal motion and stability.
Each zygapophysial joint is formed by the articulation between the superior articular facet of a vertebra
The orientation of the facet joints varies along the spine and influences movement. In the cervical region,
Functionally, the zygapophysial joints contribute to spinal stability, load distribution, and guided motion between vertebrae. Clinically,
