When you adjust the spine you effect the liver. Here is some great information and research on just how powerful and awesome you are as a chiropractor! Liver Innervation (Friedman et al 1996, Gardemann et al 1987, Gardemann et al 1992, Koepchen 1986, Nijima 1977, Royden 2005, Staines 2006, Walton 1989, Wilkinson 1993) The autonomic innervation of the liver is both parasympathetic (from occiput-atlas- axis region) via the vagus nerve and sympathetic (segments T6-9). Stimulation of the sympathetic system increases the delivery of glucose, urate and lactate. It reduces the ketogenesis, the intake of ammonia and the flow of gall. An overflow of noradrenalin in the hepatic vein will also result. Sympathetic stimulation decreases the blood flow in the liver and closes the sinusoids in the liver tissue. Parasympathetic stimulation results in re-opening of the sinusoids in the liver. The actions of the sympathetic nervous system are modulated by the hormones glucagon, insulin, adrenalin, noradrenalin, vasopressin and angiotensin. Electrical stimulation of the ventromedial hypothalamus nucleus (VMH) (sympathetic) causes glycogenolysis in the liver while an electrical stimulation of the lateral hypothalamic nucleus (LH) (vagus nerve, parasympathetic) causes glycogenesis. This glycolysis-glycogenesis mechanism is also under modulation by blood insulin levels. The sympathetic nervous system also functions as a regulating centrer for lipolysis in fatty tissue (adipose tissue) via the sympathetic innervation of brown adipose tissue. Both generation and lysis of the fatty tissue is stimulated by sympathetic action. This occurs only in the brown adipose, not in the white adipose. Treatment of adipose via stimulation of the sympathetic system (via osteopathic treatment and sports activity) must be combined with decreased fat intake. The parasympathetic system plays no part in the metabolism of fatty tissue. Stimulation of both sympathetic and parasympathetic influences will increase the rate of liver regeneration after, for example, resection of liver tissue. The afferent supply is via the vagus nerve: receptors in the liver detect changes in the hepatocellular energy balance and communicate this information to the hunger centre in the brain via the vagus nerve (Langhans 1998). Via baroreceptors in the portal vein and in the liver itself, information concerning the pressure gradient is sent to the central nervous system.
