Figure 6

Schemata of a transverse section of the cervical spine. (A) Anatomical structure (B) condition of the multifidus muscle severely stretched laterally a: multifidus muscle, b: facet joint, c: anterior rootlet, d: spinal nerve, e: anterior ramus, f: posterior ramus, g: medial branch of the posterior ramus, h: capsule branch of the medial branch of the posterior ramus, i: muscle branch of the medial branch of the posterior ramus, and j: lateral branch of the posterior ramus. If the muscle branch of the multifidus muscles of the medial branch of the posterior ramus is severely stretched laterally, not only the medial branch of the posterior ramus, but also the anterior and posterior rami and the anterior rootlet are simultaneously stretched and compressed against adjacent structures such as hypertrophied facet joint.
