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 ...
Hanger reflex - reflex of unclear purpose that causes the head to rotate to the right when the top sides of the head are under pressure, named because it can be easily activated with a coat hanger; Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung
The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.
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.
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.
Certain sounds, such as fingernails drawn down a blackboard, cause strong feelings of aversion or even fear in most humans.A 2004 study claimed that the blackboard sound was very similar to the warning cry of Siamang gibbons and hypothesized that a vestigial reflex is what causes the fight or flight reaction in humans.

"Drinking too much too quickly can affect breathing, heart rate, body temperature and gag reflex. In some cases, this can lead to a coma and death," the website reads. What causes alcohol poisoning?
This ear-cough reflex is also known as Arnold's nerve reflex (ANR), linked to the auricular branch of vagus nerve. It is an example of vagal hypersensitivity. [2] [3] Weakness of the respiratory muscles, tracheostomy, or vocal cord pathology (including paralysis or anesthesia) may prevent effective clearing of the airways.
