The vagus also provide sensory innervation; in the cervical esophagus, this is via the superior laryngeal nerve with cell bodies in the nodose ganglion, whereas in the remainder of the esophagus, sensory fibers travel via the recurrent laryngeal nerve or, in the most distal esophagus, via the esophageal branches of the vagus. A localized lack of nitric oxide synthase, an enzyme associated with smooth muscle relaxation, or abnormal neuronal innervation associated with decreased muscle neurofilaments, nerve terminals, synaptic vesicle protein, and neural cell adhesion molecule35 has been implicated; however, anatomic studies cannot determine whether nitric oxide synthase deficiency is a primary or secondary event,36 and nitric oxide synthase deficiency is only notable in a subset of cases.
