A zygapophysial joint (zygapophyseal, or facet joint) is a synovial joint between the superior articular process of one (lower) vertebra and the inferior articular process of the adjacent (higher) vertebra. There are two facet joints in each vertebral motion segment.

The biomechanical function of each pair of facet joints is to prevent excessive torsion (twisting) of the spine, while allowing a small amount of lateral bending and flexion and extension. These functions can be disrupted by degeneration, dislocation, fracture, and/or instability of the facet joints from trauma, osteoarthritis, and/or surgery.

A zygapophysis is a process which sticks out of an end of a vertebra to lock with a zygapophysis on the next vertebra, to make the backbone more stable.

Each typical vertebra has 4 of them: two front (prezygapophysis) and two back (postzygapophysis), two left and two right.

In anatomy, the term ligament is used to denote three different types of structures:[1]
  1. Fibrous tissue that connects bones to other bones. They are sometimes called "articular ligaments"[2], "fibrous ligaments", or "true ligaments".

vertebral column (backbone or spine) is a column of 34 vertebrae, the sacrum, intervertebral discs, and the coccyx situated in the dorsal aspect of the torso, separated by spinal discs. It houses the spinal cord in its spinal canal.

The posterior longitudinal ligament is situated within the vertebral canal, and extends along the posterior surfaces of the bodies of the vertebræ, from the body of the axis, where it is continuous with the membrana tectoria, to the sacrum.

Intervertebral discs (or intervertebral fibrocartilage) lie between adjacent vertebrae in the spine. Each disc forms a cartilaginous joint to allow slight movement of the vertebrae, and acts as a ligament to hold the vertebrae together.

The ligamenta flava connect the laminæ of adjacent vertebræ, from the axis to the first segment of the sacrum.

They are best seen from the interior of the vertebral canal; when looked at from the outer surface they appear short, being overlapped by the laminæ.
