Question of the Day
During an awake fiberoptic intubation, a patient begins coughing vigorously once the fiberoptic scope is passed into the trachea. Which of the following cranial nerve innervates the trachea?
Explanation
Various branches of the vagus nerve innervate the airway. 1. The superior laryngeal nerve supplies the epiglottis to the vocal cords. The internal branch of the superior laryngeal provides sensation, while the external branch provides motor innervation to the cricothyroid muscle. 2. The recurrent laryngeal nerve supplies the mucosa of the vocal cords and all intrinsic muscles of the larynx (excepting cricothyroid). 3. Branches of the vagus supply sensory innervation of the trachea. The cough reflex relays through the medulla with efferent limbs to the phrenic nerve, vagus, and others.
