“…ON-associated headache may occur due to abnormalities in the first three cervical nerve roots, with C2 being the predominant pain pathway. The C2 nerve root is vulnerable to injury due to its anatomical positioning in the atlantoaxial interlaminar disc space, which is prone to degenerative changes, instability, and congenital abnormalities [64]. ON has also been attributed to muscular hypertrophy and muscular spasms which have been relieved by surgical sectioning of muscles in close approximation with the GON [65].…”

“…The anterior and posterior nerve rootlets run inferolaterally, and as described by Tubbs et al [1], each of them enters an independent pocketlike protrusion of the dura mater in the thoracolumbar region. In addition, surgeons and neurologists have noted that the dorsal root ganglion (DRG) of the second cervical nerve differs in location from that of the other cervical nerves [4].…”

Cervical nerve roots and the dural sheath: a histological study using human fetuses near term

et al. 2020

We have previously reported that the thoracolumbar posterior nerve root shows a tortuous epidural course, based on studies of human fetuses near term. For comparison with the cervical nerve, examinations were conducted using frontal, sagittal and horizontal sections of cervical vertebrae from 22 fetuses at 30-38 weeks of gestation. The cervical nerve root showed a short, straight and lateral course near the zygapophysial joint. Multiple rather than single bundles of the cervical posterior root seemed to account for the majority of sensory nerve fibers innervating the upper extremity. Fasciculation of rootlets was evident near the thoracolumbar spinal cord, whereas it was seen in the dural pocket at the nerve exit from the dural sac although both sites were subdural. As in the thoracolumbar region, the nerve sheath was continuous with the dura mater and independently surrounded each of the anterior and posterior roots. Radicular arteries were few in the cervical region. In 2 of the 22 fetuses (31 weeks and 33 weeks), there was a segmental, unilateral abnormality of nerve rootlet fasciculation where the dorsal root ganglion was located lateral or peripheral to the intervertebral region. Long nerve roots running inferiorly are a necessary adaptation to the delayed and marked growth of the thoracolumbar vertebral column. In children, the cervical nerve roots are likely to be affected by movement or dislocation of the vertebrae. The segmental abnormality of the cervical nerve root may be linked to rare variations in the brachial plexus.
