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. Touching the soft palate can lead to a similar reflex response. However, in that case, the sensory limb of the reflex is the CN V (trigeminal nerve). In very sensitive ...
Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung; Hoffmann's reflex — also known as the finger flexor reflex; middle finger and thumb response. Test can indicate both neurological damage and nerve regeneration; often combined with the Babinski reflex test. Jaw jerk reflex
Stimulation of the uvula also causes the gag reflex to initiate. This is often a problem for people with uvula piercings, and a common method of inducing vomiting. [citation needed] It also acts as a food sensor/guard that aids in breathing between mouthfuls, stopping small pieces of food from being inhaled, leading to choking.
Gag reflex: The gag, or pharyngeal, reflex is centered in the medulla and consists of the reflexive motor response of pharyngeal elevation and constriction with tongue retraction in response to sensory stimulation of the pharyngeal wall, posterior tongue, tonsils, or faucial pillars.
An NPA is often used in patients who are conscious or have an altered level of consciousness [6] where an oropharyngeal airway would trigger the gag reflex. [7] [8] The use of an NPA is contraindicated when there is trauma to the face, especially the nose or if there is a suspected skull fracture. [9]
As the brain matures, certain areas (usually within the frontal lobes) exert an inhibitory effect, thus causing the reflex to disappear. When disease processes disrupt these inhibitory pathways, the reflex is "released" from inhibition and can be elicited once again, hence the term "frontal release sign".
The condition generally arises from the patient's knuckles making contact with the incisor teeth during the act of inducing the gag reflex at the back of the throat with their finger(s). [ 3 ] This type of scarring is considered one of the physical indicators of a mental illness , and Russell's sign is primarily found in patients with an eating ...
