_Spleen_: The coeliac plexus, the left semilunar ganglion, and the left vagus and right phrenic nerves give off branches which form the splenic plexus. Spinal connection by way of ninth dorsal nerve, by rami communicantes to gangliated cord to great splanchnic nerve to coeliac plexus to splenic plexus. Many nerve pathways like this one are less indirect than they sound; various names have been given to different parts of the same pathway through which, often, the axons pass without interruption. On the way from the cerebral cortex to one of the abdominal viscera there may be only three, sometimes four or five, neurons connected end to end. _Duodenum_: Coeliac plexus by way of duodenal branches of hepatic plexus and branches from the superior mesenteric plexus. Spinal connection from eighth dorsal nerve and possibly branches from the upper lumbar ganglia of the sympathetic may join the superior mesenteric plexus, as results in duodenal disease are occasionally reported following specific adjustment of L 1 or 2. _Jejunum and Ileum_: Connection same as for duodenum, by superior mesenteric plexus. Adjustment of L 2 in typhoid fever is undoubtedly correct so that it is probable that the lumbar ganglia send branches to this vicinity. _Peritoneum_: Nerve supply to the peritoneum is rather general owing to its great extent. It is supplied by the sympathetic from both the lower thoracic and lumbar portions of the gangliated cord through the various abdominal plexuses and in general it may be said that any localized peritoneal disease will yield to the same adjustment as would be made for disease in the immediately subjacent organ. _Suprarenal Capsules_: These important glands are supplied by amyelinic fibres derived from the gangliated cord by the lesser splanchnic nerve and connecting with pre-ganglionic fibres from the tenth dorsal nerve. The suprarenal plexus is an offshoot of the coeliac. _Kidneys_: Tenth, eleventh, and twelfth dorsal nerves by way of lesser and least splanchnic nerves to renal plexus, an offshoot of the coeliac. McConnell’s experiments and the frequently duplicated clinical feats of Chiropractors prove this to be a vital and dominant nerve pathway in kidney disease. _Ureters_: Nerves derived from inferior mesenteric, pelvic, and spermatic plexuses. Most important connection seems to be from first lumbar nerve by lumbar ganglia to inferior mesenteric plexus. _Caecum and Vermiform Appendix_: The inferior mesenteric plexus, which supplies these organs probably carries to them chiefly fibres derived from the lumber ganglia which complete a connection with the second lumbar vertebra, especially on the right side. _Colon_: Third and fourth lumbar vertebrae, influencing lumbar ganglia and thus inferior mesenteric plexus.
