Vertebra C6

The sixth cervical vertebra C6 is a typical cervical vertebra with several distinct anatomical features. It consists of a vertebral body, a vertebral arch, and several processes.

The uncinate processes at the C6 level are relatively high, measuring approximately 5.8 to 6.1 mm, which is significant for the involvement in cervical spondylosis. The anteroposterior diameter of the intervertebral foramina at C6 is smaller compared to other cervical levels, which can predispose this region to nerve root compression by uncovertebral osteophytes.

The vertebral artery typically enters the transverse foramen of C6 in the majority of individuals, which is an important consideration during surgical approaches to this region.

The spinous process of C6 is the second longest in the cervical spine, serving as an attachment point for several muscles, including the trapezius and rhomboideus minor, which are important for neck movement and stability.
