Hiccup is the process by which the body wants to get rid of the load with the so-called vagus nerve.
The vagus nerve connects many of the internal organs with the Central nervous system. He passes from the chest into the abdomen, closely adhering to the esophagus. Together with esophagus this nerve is squeezed through a narrow opening in the diaphragm - the muscle-tendon partition that separates the chest cavity from the abdominal. He then goes to the stomach and other abdominal organs.
This is the most narrow place in the aperture area is the center of origin of the hiccups. When hasty meal, when through the esophagus are quite large pieces of food, the vagus nerve is injured: pressed and irritable. This is possible even with overeating, as well as in an uncomfortable position, when the nerve is compressed, and even when frightened, when there is a sharp breath. Babies hiccup happens when they get cold.
Compression of this nerve is fraught with dysfunction of many organs, so the body quickly and actively responds to the resulting inconvenience. It sends a signal to the Central nervous system. And she, in turn, activates the phrenic nerve, which is responsible for the contraction of the diaphragm.
Hiccups are the result of regular ("pulsing") activity of the phrenic nerve, which causes the diaphragm to contract a powerful and sharp movements. The sound that occurs is the result of the abrupt closing of the glottis. Hiccup is an involuntary reaction, the so-called unconditional reflex, that is, we cannot consciously control.

Some advise to "cure" tausaga with fright, but it is very questionable means, and for children - just dangerous!
All these actions help to reduce pressure on the vagus nerve in the esophageal opening of the diaphragm. As soon as this pressure drops to nothing, hiccup goes. It usually lasts from 5 to 15 minutes.
