What is the reference point for a typical cervical (C3-C5) subluxation?

• A. laminae pedicle jxn
• B. foramen magnum
• C. body
• D. transverse process

Answer: (C)

In cervical subluxation assessment, the position of one vertebral body relative to the adjacent one is what you’re measuring. The vertebral body serves as the stable reference point because it is the main weight-bearing, rigid element that defines the alignment between levels. For a typical C3–C5 subluxation, you’re looking at how the vertebral body shifts anteriorly or posteriorly with respect to the neighboring vertebra, not the other surrounding structures. The laminae–pedicle junction, the foramen magnum, and the transverse process aren’t used as the standard reference for this sagittal misalignment; they relate to other aspects of anatomy or other types of assessment. Therefore, the body is the correct reference point.
