C4 Vertebra, Lateral View

Description

Positioned in lateral profile, the C4 cervical vertebra is presented with the vertebral body anteriorly and the vertebral arch and spinous process posteriorly, emphasizing the sagittal depth of the centrum. Superior and inferior articular processes project at the junction of pedicle and lamina, their facet surfaces oriented to support cervical flexion and extension while limiting excessive rotation. The transverse process extends laterally, with the transverse foramen expected just inferior to the superior articular facet and anterior to the posterior tubercle, a defining cervical landmark. C4 sits at the functional midpoint of the cervical lordosis and is a common reference level when correlating surface anatomy to imaging, airway management, and anterior neck surgery. The relationship between the uncinate processes of the vertebral body and the adjacent intervertebral disc helps explain cervical spondylosis patterns, where uncovertebral osteophytes can narrow the intervertebral foramen and contribute to radicular symptoms. Facet (zygapophysial) joint arthropathy at mid-cervical levels also localizes well on a true lateral view, where you can appreciate the overlap of superior and inferior articular processes and the posterior elements forming the cervical canal boundary. Small structure, big consequences. Use this lateral C4 vertebra illustration in gross anatomy and musculoskeletal teaching when introducing typical cervical vertebrae, vertebral levels, and the distinguishing features from C1, C2, and C7. It also fits neuroradiology primers and spine surgery publications that need a clean anatomical reference for correlating lateral radiographs, CT sagittal reconstructions, and level-specific operative notes (for example, anterior cervical discectomy and fusion planning).
