This study explores atlas movement and the direct relationship between vectored adjusting of the atlas and the Cl nerve root.

The atlas is moved by the muscles of the suboccipital triangle, which in turn are innervated by the C1 nerve. The muscles dictate the patterns of motion in the upper cervical spine, as well as provide much of the stability of the vertebrae. Since the muscle tissue has abundant nerve supply, joint dysfunction can cause the muscles to spasm or become hypertonic, often compensatory for disturbances below, i.e., the entire cervical region with full body implications.

Because of the anatomic relationship of atlas and occiput with the brain stem, the subluxation may affect the cervical spinal cord, first and second cervical spinal nerves, superior cervical ganglion, and cranial nerves X, XI, and XII.

The properly vectored adjustment (the Summa of all chiropractic) will release the functional irritation of the C1 nerve root and subsequently reduce the subluxation.
