Axis's Transverse Process In Anterior View

Description

Axis (C2) transverse process is shown from an anterior perspective, highlighting the lateral bony projection that extends from the vertebral arch and frames the transverse foramen (foramen transversarium). The foramen sits lateral to the vertebral body and pedicle region, forming a rounded osseous ring that would be positioned anterolateral to the spinal canal in anatomical orientation. Medially, the base of the transverse process blends into the lateral mass region; laterally, the process tapers toward its tubercular contours, with cortical margins and cancellous transitions visible at the cut bony edges. Small but unforgiving anatomy. Clinically, the transverse foramen of C2 matters because it transmits the vertebral artery and accompanying venous plexus as they ascend through the cervical transverse foramina before curving toward the atlas, so any fracture line, osteophyte, or misplaced instrumentation here carries a real risk of vascular injury. In trauma, atypical C2 fracture patterns and comminution can involve the transverse process, and surgeons planning posterior C1 to C2 fixation or transarticular screw trajectories often correlate bony corridors with the expected artery position relative to the foramen transversarium. The anterior viewpoint supports teaching the relationship between the vertebral body, pedicle-lateral mass complex, and the foramen’s anterior rim, which is also the margin you reference when interpreting CT in suspected vertebral artery compromise. Use this illustration in gross anatomy and radiologic anatomy modules on the cervical spine, in neurosurgery or orthopedic spine lectures on C2 fixation planning, and in publisher figures discussing vertebral artery vulnerability in upper cervical fractures.
