Cervical Vertebra's Posterior Tubercle, Lateral View

Description

Posterior tubercle of a cervical vertebra anchors the lateral aspect of this image, projecting from the posterior root of the transverse process in a fixed lateral view of the neck skeleton. The transverse foramen (foramen transversarium) lies immediately medial to the transverse process, while the anterior tubercle sits anterior to the foramen, creating the characteristic anterior and posterior tubercle pair separated by the intertubercular groove. Superior and inferior margins of the transverse process relate to the intertransversarii attachments, and the posterolateral contour of the articular pillar with the superior and inferior articular processes is typically visible just medial and posterior to the tubercle. Bone is the focus. Edges read crisply. This relationship matters whenever you need to communicate how close the vertebral artery and accompanying veins can be to the transverse process, since the artery commonly traverses the transverse foramina from C6 to C1 and becomes vulnerable in transverse process fractures or surgical exposure. A lateral perspective also clarifies how the posterior tubercle sits posterior to the expected course of the cervical spinal nerve as it exits the intervertebral foramen and passes between the anterior and posterior tubercles, a detail that helps when teaching cervical plexus blocks and selective nerve root injections. The illumination favors relief of the tubercle and the rim of the transverse foramen, which is where learners often lose the three-dimensional relationship on flat diagrams. Use this illustration in head and neck anatomy lab manuals, spine surgery and trauma textbooks, and radiology teaching files that correlate bony landmarks with CT of the cervical transverse processes and foramina. It also supports patient-facing explanations of transverse process fractures and vertebral artery screening after high-energy lateral neck trauma.
