The cough reflex occurs when stimulation of cough receptors in the respiratory tract by dust or ... Unlike other areas responsible for involuntary actions like ...
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 ...
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 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.
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 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 ...
The Hering-Breuer reflex that terminates inhalation to prevent over inflation of the lungs, and the reflex responses of coughing, airway constriction, and hyperventilation. The upper airway receptors are responsible for reflex responses such as, sneezing, coughing, closure of glottis, and hiccups.
