The Cervical Spine Section Viewed Laterally

Description

Seen in lateral profile, the cervical vertebral column is represented as a stacked series of vertebral bodies from C1 through C7, separated by intervertebral discs and aligned in a gentle cervical lordosis. Posterior to the vertebral bodies, the vertebral arches form the spinal canal, with spinous processes projecting posteriorly and appearing shorter and often bifid in the mid cervical levels. Transverse processes extend laterally, and at C3 to C6 their anterior and posterior tubercles outline the transverse foramina region, a key cervical feature even when simplified in a sectional rendering. Superiorly, the atlas and axis are inferred by the transition to the craniovertebral junction. Alignment is the story here. Lateral cervical anatomy matters because small changes in segmental alignment translate into meaningful changes in canal diameter and foraminal space. Degenerative disc disease with uncovertebral and facet arthrosis most often narrows the intervertebral foramina at C5 to C7, correlating with C6 and C7 radiculopathy patterns, while posterior osteophytes and ligamentum flavum infolding contribute to cervical spondylotic myelopathy. This perspective also matches the mental model used during anterior cervical discectomy and fusion planning, where disc height restoration and lordosis correction are assessed level by level rather than in isolation. Use this illustration for gross anatomy labs covering the neck, spine biomechanics lectures, and clinical correlations on whiplash injury and degenerative cervical spine disease. It also fits radiology teaching files as a conceptual companion to lateral cervical radiographs and mid sagittal CT or MRI. Anatomical accuracy verified by SciePro's Medical Advisory Board.
