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.
The cough reflex occurs when stimulation of cough receptors in the respiratory tract by dust or other foreign particles produces a cough, which causes rapidly moving air which usually remove the foreign material before it reaches the lungs.
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 main reason is that patients’ cough reflex is enhanced for a month or more even from the simplest common cold, said Dr. Peter Dicpinigaitis, director of Montefiore Cough Center in New York City.
"The way we recommend to clean your ears is just with a washcloth or a towel on your finger." "Clean the outer area of the ear and just use your towel to mop up any water or gunk that's accumulated.
Abdominal reflex; Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. Acoustic reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities.
The good news is that you don't need to be worrying too much about keeping your ears clean. Wax is normal and good for the ear.
The other clearance mechanism is provided by the cough reflex. [2] Mucociliary clearance has a major role in pulmonary hygiene . MCC effectiveness relies on the correct properties of the airway surface liquid produced, both of the periciliary sol layer and the overlying mucus gel layer , and of the number and quality of the cilia present in the ...
