Cervical Vertebra's Anterior Tubercle, Lateral View

Description

Anterior tubercle of a cervical vertebra projects from the anterolateral margin of the transverse process and sits anterior to the foramen transversarium in this lateral view of the neck skeleton. Posterior to it, the posterior tubercle forms the other limb of the transverse process, with the intertubercular (transverse) groove spanning between them where the anterior ramus of a cervical spinal nerve courses laterally. The vertebral body lies medial, while the articular pillar and zygapophysial (facet) region rise posteriorly and slightly superiorly relative to the tubercle. Small structure, high value. Clinically, the anterior tubercle matters because it is the bony interface for key muscular and fascial attachments and a landmark for neurovascular procedures. The anterior tubercle of C6, often termed the carotid tubercle (Chassaignac tubercle), can be palpated to compress the common carotid artery against the transverse process during hemorrhage control, and it sits adjacent to the sympathetic trunk and vertebral artery as the artery ascends through the foramina transversaria. In a fixed lateral perspective, the illustration clarifies the anterior versus posterior tubercle relationship and the position of the transverse groove, a common point of confusion when learners translate between surface palpation, cross sectional imaging, and dry bone anatomy. Use this illustration in gross anatomy and musculoskeletal modules covering the cervical spine, or in anesthesiology teaching materials to discuss landmarks and risk structures for cervical nerve root blocks and interscalene approaches, where needle trajectory relates to the transverse process rather than the intervertebral foramen. It also supports surgical anatomy discussions of anterior cervical approaches, emphasizing why dissection stays medial to the carotid sheath and respects the vertebral artery corridor.
