Superior Articular Process Of The Cervical Vertebra, Posterior View

Description

Processus articularis superior of a typical cervical vertebra occupies the posterolateral corner of the vertebral arch, positioned at the junction where the pedicle transitions into the lamina. From this posterior perspective, the superior articular facet sits superior to the lamina and medial to the transverse process region, with its smooth cartilaginous surface oriented to meet the inferior articular facet of the vertebra above at the zygapophysial (facet) joint. The pedicle forms the anterolateral strut leading toward the vertebral body, while the lamina sweeps medially toward the base of the spinous process. Compact cortical margins and trabecular bone texture define the load-bearing geometry. Cervical facet joints guide motion and frequently generate pain, and the superior articular process is the bony substrate for both degenerative facet arthropathy and post-traumatic facet injury after whiplash. This posterior, close-range framing makes it easy to teach how the articular pillar relates to the lamina and pedicle, a relationship that matters when planning posterior approaches where a laminotomy, medial facetectomy, or foraminotomy must respect the joint to avoid iatrogenic instability. A small structure. Big consequences. Use this illustration in gross anatomy lab manuals to anchor the concept of the vertebral arch and zygapophysial joint orientation, and in spine surgery or interventional pain publications when explaining medial branch blocks or radiofrequency neurotomy targeting the facet joint complex in the cervical region.
