When ~nerves~ bundle together outside of the |spinal cord|, the bundle is called a ganglion. A number of these ganglia are located along the exterior |spinal cord|, connected together in the ~nerve~ pathway called the ~nerve~ trunk. The sympathetic ~nerve~ trunk runs along the |vertebral column| and features five main ganglia. These include the celiac, the cervical, the splanchnic, the superior mesenteric, and the inferior mesenteric ganglia. The celiac ganglion is resopnsible for supplying ~nerves~ to the |adrenal glands|, the |duodenum|, the |kidneys|, the |pancreas|, and the |stomach|. The cervical ganglion supplies ~nerves~ to the |heart|, the face, the neck, and the tympanum. The splanchnic ganglion supplies ~nerves~ to the viscera, and the superior and inferior mesenteric ganglia supply ~nerves~ to the intestines and to the |bladder| and gonads, respectively. The parasympathetic ganglia are located in the |brain| and |medulla| oblongata and include the ciliary, optic, and sphenopalatine ganglia.
