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.
Stimulation of the auricular branch of the vagus nerve supplying the ear may also elicit a cough. 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.
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 ...

Two of the most overlooked symptoms of whooping cough are a runny nose and congestion. That's one of the things that makes it so tricky to catch early. "Symptoms may mirror that of the common cold.
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.
