Correct Answer � C Explanation |
 |
– The gag reflex (pharyngeal reflex) is triggered by touching the soft palate or posterior pharynx.
– 9th cranial nerve (Glossopharyngeal nerve): Afferent limb; senses stimulation in the throat.
– 10th cranial nerve (Vagus nerve): Efferent limb; contracts pharyngeal muscles → gagging sensation.
