Vagus nerve<br />

<strong>The</strong> vagus nerve is the tenth cranial nerve. It carries the parasympathetic outflow to the<br />

heart and other visceral organs. <strong>The</strong> most important clinical effect of the vagus nerve is bradycardia.<br />

<strong>The</strong> vagus nerve can be stimulated by many different types of noxious stimuli, including laryngoscopy,<br />

uterine or cervical traction and opthalmic pressure. It can also be stimulated by<br />

emotional triggers. If you have fainted at the sight of blood, then you have experienced the<br />

impact of your own vagus nerve!<br />
