The vagus nerve is the tenth cranial nerve, branching off of the medulla oblongata and extending upward and downward into the abdomen. An important nerve, the vagus divides into several branches which innervate vital structures in the body. These include the auricular, bronchial, cardiac (inferior and superior), celiac, oesophageal, gastric, hepatic, laryngeal (recurrent and superior), meningeal, pharyngeal, and pyloric branches.
