The Anatomy Of The Posterior Tubercle Of The Cervical Vertebra

Description

Arising from the transverse process of a typical cervical vertebra, the posterior tubercle appears as a blunt projection posterior to the transverse foramen and lateral to the pedicle and lamina. The animation steps through sequential viewpoints, orienting the viewer from a posterior cervical spine perspective toward a lateral oblique, so the posterior tubercle can be read in relation to the anterior tubercle and the intertubercular (costotransverse) groove between them. As the vertebra rotates, the spinous process and articular pillars intermittently frame the tubercle, clarifying its position on the posterolateral margin of the neck skeleton. Clinically, the posterior tubercle matters because it anchors key surface and procedural landmarks in the cervical region. The costotransverse groove, bounded by the anterior and posterior tubercles, transmits the ventral ramus of the cervical spinal nerve; understanding that corridor helps explain patterns of radicular pain and the proximity of the nerve to osseous margins during foraminal narrowing from uncovertebral osteophytes. Motion adds clarity here: a static view often collapses the transverse foramen, tubercles, and groove into a single contour, while the animated rotation separates these elements in depth so you can reliably identify the posterior tubercle without confusing it with the superior articular process or the posterior arch contours. Use this sequence in gross anatomy and osteology teaching to reinforce cervical vertebra identification, in radiology education when correlating axial CT or oblique reformats with bony landmarks around the transverse process, and in spine surgery publishing to support discussions of lateral mass fixation corridors and adjacent nerve root anatomy.
