Posterior Tubercle Of The Cervical Vertebra In Anterior View

Description

Posterior tubercle of a typical cervical vertebra (most consistent with C3 to C6) is centered on the transverse process, positioned posterior to the anterior tubercle and lateral to the vertebral body. From an anterior viewpoint, the posterior tubercle sits inferior and posterior to the anterosuperior margin of the foramen transversarium, creating the paired tubercle profile that brackets the transverse process. A shallow sulcus between the anterior and posterior tubercles marks the expected course of the cervical spinal nerve and accompanying vessels as they pass laterally from the intervertebral foramen. Bone surface detail is emphasized at the tubercle apex and at the transverse process margins. A key landmark. Clinically, the posterior tubercle is a palpable and image-recognizable reference used to orient the neck in fluoroscopy, CT, and cadaveric dissection when identifying the transverse process and the nearby vertebral artery. The relationship between the posterior tubercle and foramen transversarium helps clarify why needle trajectories for cervical nerve root blocks and sympathetic chain procedures must respect the artery’s anterolateral position relative to the uncinate process and transverse process. An anterior view is also useful when teaching the distinction between cervical transverse processes and thoracic transverse processes, since the cervical anterior and posterior tubercles (and the intertubercular groove) provide a quick discriminant that ties directly to neurovascular anatomy. In gross anatomy and radiologic anatomy courses, this illustration supports labeling exercises on the cervical skeleton, with clean separation of transverse process features for quizzes and lab manuals. Surgical education teams can also place it alongside stepwise diagrams for anterior cervical approaches to reinforce bony orientation before discussing disc space levels and foraminal targets.
