Articular Facet Of The Cervical Vertebra, Inferior View

Description

Inferior articular facet of a typical cervical vertebra occupies the posterolateral aspect of the vertebral arch, forming the caudal half of the zygapophysial (facet) joint with the superior articular facet of the vertebra below. From this inferior perspective, the smooth hyaline cartilage bearing surface sits just lateral to the base of the spinous process and posterior to the pedicle, with the lamina sweeping medially toward the vertebral foramen. The facet’s rim is continuous with cortical bone, and adjacent landmarks such as the articular process, lamina, and portions of the transverse process frame the joint surface in fixed spatial relation. Sharp bony margins stand out. Facet orientation in the cervical spine drives coupled motion and also shapes pathology, so a clean inferior view helps you teach why subaxial facets (C3 to C7) tend to be more oblique and why the C2 to C3 region behaves differently. Degenerative change at the zygapophysial joints is a frequent contributor to axial neck pain and cervicogenic headache, and procedures like cervical medial branch blocks and radiofrequency ablation depend on accurate understanding of the articular pillar and the joint line. The polished surface and surrounding cortical contour in this image support direct comparison with oblique radiographs and axial CT, where sclerosis, osteophytes, and joint space narrowing cluster along the facet margins. Use this illustration in gross anatomy and musculoskeletal anatomy courses when introducing the vertebral arch and posterior elements, and in spine modules that pair cadaveric anatomy with CT-based correlation. It also suits clinical lectures and patient-facing publisher graphics on cervical spondylosis, whiplash-associated facet pain, and posterior approach landmarks for facet injections.
