Which feature of cervical vertebrae transmits the vertebral artery and vein?

Explanation:
Cervical vertebrae have a transverse foramen in each transverse process, and this opening is the route for the vertebral artery and its accompanying vein. The artery travels upward through these foramina, supplying the brainstem and posterior brain regions, starting around the lower cervical levels and continuing up to the atlas before entering the skull via the foramen magnum. The other structures don’t form passages for these vessels—the spinous process is for muscle and ligament attachment, the body bears weight and articulates with adjacent bodies, and the costal facets are for rib articulation in the thoracic region.
