The middk thoracic spinal nerves influence the spleenthrough their connection with the corresponding thoracicganglia of the gangliated cord, which latter communicate withthe splanchnic nerves to the semilunar ganglion of the solarplexus. The left semilunar ganglia, together with branchesfrom the celiac plexus and the right vagus nerve, form thesplenic plexus, which accompanies the splenic artery to thesubstance of the spleen. The sixth dorsal spinal nerve has the most markedinfluence upon the spleen. The Innervation of the Pancreas.—The innervation of thepancreas is derived from the following nerves: 1. The upper four cervical spinal nerves through theirconnection with the vagus nerve have an indirect influence onthe pancreas. 146 SPINAL ADJUSTMENT. Fig, 28. Parts Influenced by the TenthDorsal Nerve. ORGANS OF THE ABDOMEN 147 2. The middle cervical nerves, especially the fourth, byforming the phrenics also influence the pancreas. 3. The middle thoracic spinal nerves through their con-nection with the semilunar ganglia and solar plexus have thegreatest effect on the pancreas and adrenals. The eighthdorsal spinal nerves have the most marked influence on thepancreas. Filaments from the splenic plexus form the pan-creatic plexus and it is the eighth thoracic nerve which entersmost largely into the formation of this portion of the splenicplexus. The Innervation of the Stomach.—The innervation of thestomach is derived from the following nerves: 1. The vagus by its terminal branches supplies the stom-ach; the one on the right being distributed to the back part,and the left to the front part of the organ. Its communicationwith spinal nerves throug
