Atypical cervical spondylotic radiculopathy resulting in a hypertensive emergency during cervical extension: A case report and review of literature

Figure 5 Overextension of the neck leads to further compression of the spinal ganglia by the nucleus pulposus tissue. Following pressure stimulation, the spinal nerves directly excite the neck's sympathetic ganglia via bidirectional nerve fibers (represented by green dashed lines), thus activating the sympathetic nervous system and inducing a rapid blood pressure increase.
