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 ...
Pharyngeal reflex — also known as the gag reflex. Photic sneeze reflex — a sneeze caused by sudden exposure to bright light. Plantar reflex — in infants up to 1 year of age, a curling of the toes when something rubs the ball of the foot.

Retching (also known as dry heaving) is the reverse movement (retroperistalsis) of the stomach and esophagus without vomiting. [1] It can be caused by bad smells or choking, or by withdrawal from certain medications, or after vomiting has completed.
Dysphagia, dysarthria, flaccid paralysis, muscle atrophy, drooling of saliva, reduced or absent gag reflex Bulbar palsy refers to a range of different signs and symptoms linked to impairment of function of the glossopharyngeal nerve (CN IX), the vagus nerve (CN X), the accessory nerve (CN XI), and the hypoglossal nerve (CN XII).
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]
Backstage photos show what went into executing the viral gag. John Cena, mostly in the nude, pulled off one of the best bits at the 96th Oscars on Sunday. Backstage photos show what went into ...
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 ...
Reflexes, such as the cough and gag reflexes, are also means of judging LOC. [12] Once the level of consciousness is determined, clinicians seek clues for the cause of any alteration. [9] Usually the first tests in the ER are pulse oximetry to determine if there is hypoxia, serum glucose levels to rule out hypoglycemia. A urine drug screen may ...
