Sixth Cervical Vertebra (C6)

Description

Centered on the sixth cervical vertebra (C6), the illustration emphasizes the relatively small vertebral body anteriorly and the large vertebral foramen posterior to it, bounded by the pedicles and laminae of the vertebral arch. Lateral to the body, the transverse processes project toward the transverse foramina, a key cervical landmark for the vertebral vessels, while the superior and inferior articular processes sit posterolaterally with their facets oriented to guide flexion and rotation. A short, typically bifid spinous process extends posteriorly in the midline. Adjacent intervertebral discs are shown between the vertebral bodies, clarifying segmental spacing at the C5 to C6 and C6 to C7 levels. C6 matters because it anchors several practical neck landmarks and is a frequent reference point in clinical anatomy. The anterior tubercle of the C6 transverse process corresponds to the carotid tubercle (Chassaignac’s tubercle), used to compress the common carotid artery and as a surface guide during cervical sympathetic blocks. C6 to C7 is also a common level for cervical radiculopathy and degenerative disc disease, and understanding the relationship of the uncovertebral region and zygapophysial joints to the intervertebral foramina helps explain why osteophytes can narrow the nerve root exit. Small body, big canal. That proportion matters when contrasting cervical stenosis patterns with thoracic or lumbar segments. Use this artwork in gross anatomy and musculoskeletal courses when teaching typical cervical vertebrae, in radiology primers that correlate bony landmarks with axial CT or lateral radiographs, and in spine surgery or anesthesia materials that discuss anterior cervical approaches and surface anatomy at the C6 level. It also fits well in patient-facing education on cervical disc herniation and radicular pain patterns referenced to C6 dermatomal and myotomal findings.
