Figure 2

Theoretical model of the impact of vertebral subluxation on neural information flow and on the extended neuro-endocrine immune supersystem. Green arrows represent normal afferent and efferent neural information flow; red arrows indicate altered afferent or efferent flow via vertebral subluxation (blue box). The chiropractic adjustment delivered to eliminate or reduce vertebral subluxation would restore normal afferent/integrative/efferent flow (green arrows).

NS, nervous system; ES, endocrine system; IS, immune system; SSA, somatosensory afferent; GSA, general somatic afferent; SVA, special visceral afferent; GVA, general visceral afferent
