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 gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. Touching the soft palate can lead to a similar reflex response. However, in that case, the sensory limb of the reflex is the CN V (trigeminal nerve). In very sensitive ...
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.
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 ...
That doesn’t mean you should steer clear of the doctor if your cough is dragging on that long, but it does mean you could be dealing with an annoying cough for a while, even if you don’t have ...
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.
