The vagus nerve is also responsible for regulating inflammation in the body, via the inflammatory reflex. [7] Efferent vagus nerve fibers innervating the pharynx and back of the throat are responsible for the gag reflex. In addition, 5-HT 3 receptor-mediated afferent vagus stimulation in the gut due to gastroenteritis is a cause of vomiting. [8]
Damage to the vagus nerve, [2] chemotherapy-induced neuropathy, [3] and autonomic neuropathy. [4] Risk factors: Diabetes, abdominal or esophageal surgery, infection, certain medications that slow the rate of stomach emptying, scleroderma, nervous system diseases, and hypothyroidism. [2] Diagnostic method
Diabetes: High blood sugar levels over time can damage the vagus nerve and 'pacemaker' cells in the stomach muscles. This damage disrupts stomach muscle functions by interfering with normal nerve ...
Highly selective vagotomy refers to denervation of only those branches supplying the lower esophagus and stomach (leaving the nerve of Latarjet in place to ensure the emptying function of the stomach remains intact). It is one of the treatments of peptic ulcer. Vagotomy can be used in the surgical management of peptic (duodenal and gastric ...
The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left. The right and left nerves are not symmetrical, with the left nerve looping under the aortic arch ...
A Nissen fundoplication, or laparoscopic Nissen fundoplication when performed via laparoscopic surgery, is a surgical procedure to treat gastroesophageal reflux disease (GERD) and hiatal hernia. In GERD, it is usually performed when medical therapy has failed; but, with a Type II (paraesophageal) hiatus hernia, it is the first-line procedure.
The pharyngeal branch of the vagus nerve is the principal motor nerve of the pharynx. It represents the motor component of the pharyngeal plexus of vagus nerve and ultimately provides motor innervation to most of the muscles of the soft palate (all but the tensor veli palatini muscle), and of the pharynx (all but the stylopharyngeus muscle).

Electrical stimulation of vagus nerve. Vagus nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an add-on treatment for certain types of intractable epilepsy, cluster headaches, treatment-resistant depression and stroke rehabilitation.
