Anterior Tubercle Of The Cervical Vertebra In Anterior View

Description

Anterior tubercle of the cervical transverse process stands out on the lateral aspect of a mid to lower cervical vertebra in anterior view, projecting anteriorly from the transverse process just lateral to the vertebral body. Medial to the tubercle lies the foramen transversarium, the osseous canal that transmits the vertebral artery and vein (classically C6 to C1) and the accompanying sympathetic plexus. Posterior to the anterior tubercle, the posterior tubercle and the intervening sulcus for the cervical spinal nerve are suggested by the typical configuration of a cervical transverse process. Superiorly and inferiorly, the vertebral body margins and uncovertebral regions frame the transverse process, reinforcing the compact, stacked geometry of the cervical spine. C6 deserves special attention because its anterior tubercle forms the carotid tubercle (Chassaignac tubercle), a palpable landmark used to compress the common carotid artery and to orient clinicians during anterior neck procedures. This region also anchors the anterior scalene muscle on C3 to C6, so the relationship between the anterior tubercle and the foramen transversarium matters during scalene blocks and when evaluating thoracic outlet syndromes. An anterior viewpoint clarifies what sits anterior to the vertebral artery canal and what lies medial toward the longus colli and prevertebral space. Small bone, big landmark. In undergraduate gross anatomy and head and neck courses, this illustration supports teaching of cervical vertebra identification (anterior and posterior tubercles, foramen transversarium) and surface anatomy correlations around the carotid sheath. It also fits surgical education and publishing needs for anterior cervical approaches, where staying medial to the foramen transversarium helps reduce vertebral artery risk and the carotid tubercle guides level localization.
