Predict the impact on the gag reflex when a person has a damaged vagus nerve (X)
What will be an ideal response?
Somatic motor neurons of the vagus nerve (X) are responsible for triggering contractions of the muscles of the pharynx to produce the "gag" during the gag reflex. Thus, a person would not be able to elicit a gag reflex if the vagus nerve is damaged.
