Gross anatomy
They are symmetrical synovial-lined joints with a fibrous capsule that connect the articular facets of the vertebrae. The superior facet of the lower vertebra articulates with the inferior facet of the vertebra above.
The facet joints are situated between the pedicle and lamina of the same vertebra and form the articular pillars that act to provide structural stability to the vertebral column as a whole.
Attachments
The facet joints kept fixed in position by the posterior ligamentous complex.
Innervation
Pain sensation of the facet joint capsule and synovial folds is provided by the medial branch of the dorsal ramus .
