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 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 ...
