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).
I HAVE NO GAG REFLEX BTW MEME SERIES
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.

I HAVE NO GAG REFLEX BTW MEME SKIN
To conclude, reports have it that TikTok is possibly onto something on this particular trick, although one can probably stop pinching his skin between his thumb and finger and rather apply pressure to his wrist at the "P-6" site. It's covering the spectrum of gag reflexes from mild end nausea to the severe end that concludes in vomiting. Meanwhile, a study published in Nature indicated, the mode of action in regulating gag reflex though acupuncture is not completely understood. Published in the National Library of Medicine, the study applied pressure to the acupuncture point, specifically the P-6 Neikuan, located on the wrist, which has been used in the Far East for thousands of years for its anti-anxiety and anti-nausea properties. Nevertheless, others have tried to account for this through the application of pressure to multiple areas of a number of subjects. The study investigators concluded that applying pressure points, specifically during dental procedures, would lessen the possibility of stimulating a gag reflex, although they stressed there is a need for more studies.Īn effective approach to dampen the gag reflex is a distraction, and thus, it could be that this is what took place or that there was an effect of a placebo in play. Researchers discovered that when pressure was applied to the palm, the gag reflex moved backward, further into the mouths of the patients if the patient gagged with something not quite far into their mouth, the point which they began to gag would be further back following application of such pressure. On the basis of this scale, the study authors split subjects into a hypersensitive group and a control or expected-sensitivity group. Here, they developed a hand pressure device for the volunteers to where, which provided a constant force, and they described a GTPI or gag trigger point index scale. In this paper, the researchers wrote, 36 neurological intact subjects went through a series of gag reflex trials.
Dentists, for instance, have a specific interest in stopping the gag reflex, given their work needs them to be in what's known as the "spew zone."įirst, the research, Altering the Gag Reflex Via a Palm Pressure Point, published in the Journal of the American Dental Association, saw pressure applied to a small group of volunteers' palms prior to their receipt of dental treatment.
Studies About Stopping the Gag ReflexĪ lot of studies have looked into the matter. Another medical story has gone viral, specifically the new TikTok trick that lets one stop his gag reflex.
