Some people, for instance sword swallowers, have learned how to suppress it. ![]() Swallowing unusually large objects or placing objects in the back of the mouth may cause the pharyngeal reflex. In very sensitive individuals, much more of the brain stem may be involved a simple gag may enlarge to retching and vomiting in some. However, in that case, the sensory limb of the reflex is the CN V ( trigeminal nerve). Touching the soft palate can lead to a similar reflex response. The gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. the sensory limb is mediated predominantly by CN IX ( glossopharyngeal nerve).The CNS receives this message and sends an appropriate response via an efferent nerve (also known as a motor neuron) to effector cells located in the same initial area that can then carry out the appropriate response. Generally, a sensory receptor receives an environmental stimulus, in this case from objects reaching nerves in the back of the throat, and sends a message via an afferent nerve to the central nervous system (CNS). In a reflex arc, a series of physiological steps occur very rapidly to produce a reflex. ![]() The pharyngeal reflex is different from the laryngeal spasm, which is a reflex muscular contraction of the vocal cords. It, along with other aerodigestive reflexes such as reflexive pharyngeal swallowing, prevents objects in the oral cavity from entering the throat except as part of normal swallowing and helps prevent choking, and is a form of coughing.

A 2015 study suggested that tranquilizers can reduce anxiety and tension, which can lower the incidence of gagging. According to a 2016 study of people gagging when having an impression made of their teeth, local anesthetic was successfully used to control the gag reflex.
