Pedicle Of The Cervical Vertebra, Anatomy

Description

Cervical vertebral pedicle bridges the posterolateral margin of the vertebral body to the posterior arch, forming the bony root of the vertebral arch in a typical mid to lower neck vertebra (C3 to C7). Its short, stout cylinder sits anterior to the lamina and medial to the transverse process, with the superior and inferior vertebral notches contributing to the margins of the intervertebral foramen. Medially, the pedicle helps define the lateral wall of the vertebral canal, while laterally it relates to the transverse foramen region where the vertebral artery course becomes a practical consideration. Orientation is key. Pedicle anatomy drives much of cervical posterior fixation strategy because a few millimeters of error can violate either the spinal canal medially or the vertebral artery laterally, and the illustration emphasizes these tight spatial relationships in one fixed frame. In degenerative spondylosis, foraminal narrowing often reflects osteophytes and facet changes, but the pedicle’s notches still set the bony boundaries that frame where a nerve root can be compressed. For teaching, the pedicle’s relationship to the vertebral body, lamina, and articular processes supports clear mental mapping of how the posterior elements form a ring around the spinal cord. Use this illustration in spine anatomy lab manuals, orthopedic and neurosurgical slide decks on cervical pedicle screw trajectories, and radiology teaching files when correlating axial CT landmarks with posterior element morphology. It also suits medical-legal or device documentation where precise Terminologia Anatomica naming of the vertebral arch, pedicle, and canal boundaries matters.
