The sound produced by the involuntary contraction of the diaphragm, followed by a rapid closure of the glottis is called singultus, which is commonly known as hiccups. A cough is a sudden expulsion of air from the lungs through the mouth, while a sneeze is a sudden expulsion of air from the nose and mouth caused by irritation in the nasal passages. Eructation is another term for burping, which is the act of expelling gas from the stomach through the mouth.
