In a small portion of individuals, the auricular nerve is the afferent limb of the Ear-Cough or Arnold Reflex. [3] Physical stimulation of the external acoustic meatus innervated by the auricular nerve elicits a cough, much like the other cough reflexes associated with the vagus nerve.
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. It is an example of vagal hypersensitivity.
The hypersensitivity of vagal afferent nerves causes refractory or idiopathic cough. Arnold's nerve ear-cough reflex, though uncommon, is a manifestation of a vagal sensory neuropathy and this is the cause of a refractory chronic cough that can be treated with gabapentin. The cough is triggered by mechanical stimulation of the external auditory ...
A cough is a sudden expulsion of air through the large breathing passages which can help clear them of fluids, irritants, foreign particles and microbes.As a protective reflex, coughing can be repetitive with the cough reflex following three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually ...
The auricular branch of the vagus nerve was nicknamed "Arnold's nerve" after he described the reflex of coughing when the ear is stimulated. [2] Other eponyms that contain his name are "Arnold's ganglion" (otic ganglion) and "Arnold's canal" (a passage of the petrous portion of the temporal bone for the auricular branch of the vagus nerve.

In adults and children age 2 and older, use it only on the neck and chest to ease coughing during a cold, per the Mayo Clinic. Vicks VapoRub is made of ingredients such as camphor, eucalyptus oil ...
The vagus nerve provides an auricular branch also termed "Arnold's nerve" which also supplies the external auditory canal, thus laryngopharyngeal cancer can result in referred ear pain. This nerve is also responsible for the ear-cough reflex in which stimulation of the ear canal results in a person coughing.
A dry cough is a persistent cough where no mucus is present; this can be a sign of an infection. A chronic wet cough is a cough where excess mucus is present; depending on the colour of the phlegm, bacterial infections may be present. [16] A stress cough is when the airways of the throat are blocked to the point that it causes a reflexive spasm.
