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.
Coronary reflex; Cough reflex — a rapid expulsion of air from the lungs after sudden opening of the glottis, and usually following irritation of the trachea. Cremasteric reflex — elevation of the scrotum and testis elicited by stroking of the superior and medial part of the thigh.
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 ...
It, along with other aerodigestive reflexes such as reflexive pharyngeal swallowing, prevents objects in the oral cavity from entering the throat except as part of normal swallowing and helps prevent choking, and is a form of coughing. The pharyngeal reflex is different from the laryngeal spasm, which is a reflex muscular contraction of the ...
The exact location and functionality of the cough center has remained somewhat elusive: while Johannes Peter Müller observed in 1838 that the medulla coordinates the cough reflex, investigating it has been slow because the usual anaesthetics for experimental animals were morphine or opiates, drugs which strongly inhibit cough.

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 mucous membrane of the carina is the most sensitive area of the trachea and larynx for triggering a cough reflex. [citation needed] Clinical significance
