Animal Chiropractic Module 3 – Cervical Practice Test

No coupled motion can be found cranial to the first facet junction (C2-C3)?

True False Not enough information Only in humans

Correct Answer:

True

Explanation:

In the upper cervical spine, motion patterns differ from the lower cervical levels because the joint anatomy shapes how movement occurs. The OA (occipito-atlantal) joint mainly handles flexion and extension with only limited rotation, while the AA (atlanto-axial) joint at C1-C2 provides most of the head-and-neck rotation but doesn’t couple it strongly with lateral bending the way the mid-to-lower cervical segments do. Because of these differences, there isn’t a consistent, strong pattern of rotation plus side-bending (coupled motion) cranial to C2-C3. Therefore, the statement is true.
