Displacement of the interfacetal joint with rotational deformity may also produce a "double-appearance" of articular facets
above the level of injury reminiscent of a "bow tie".
However, he noted that it differed in one primary aspect of its configuration-the transition in inter-vertebral articular facets
occurred at a higher level of the spine that than normally occurs in modern humans.
The PCS shrew does not have an enlarged condylar process and laterally offset articular facets
separated by a groove from the body of the dentary; therefore, it differs from the Nectogalini.
A more precise description was provided by Davis (1959) who stated that in the thoracic spine the superior articular facets face posteriorly, slightly superiorly and slightly laterally (Figure 4).
This facilitation is said to occur when force is applied that aids the movement of contributing articular facets in the direction to which the zygapophysial joint motion is most inhibited.
Davis PR (959): The medial inclination of the human thoracic intervertebral articular facets.
At each level the articular facet of each superior articular process passes deep (or more anterior) to the inferior articular process of the vertebrae immediately above (Moore & Dalley 2006, Rosse & Gaddum-Rosse 1997, Standring 2005) (Figure 2).
antoni due to the fact that the trunk vertebrae of the fossil specimen possess neural spines that are not strongly indented anteriorly and posteriorly, as well as articular facets
that are broad, flat, and round in dorsal view.
Cervical spondylolysis is, however, much more rare than its lumbar counterpart and is described as a well-corticated cleft between the superior and inferior articular facets
of the articular pillar of the cervical spine.
The "hamburger bun sign" (Figure 7) refers to the normal relationship between the superior and inferior articular facets
of the cervical vertebrae, as seen on axial computed tomographic (CT) images.
The pars interarticularis is defined as the parts of the neural arch that lie between the superior and inferior articular facets
