The domestic zebra - is a domesticated species of carnivorous mammal from the canine family. It became widespread in northern Europe in the XXVII century. Gatherers were already domesticated at the end of the XXVth century, but they still fascinate scientists today because of their consumption of "light bulbs" (so popularly called glowing balls). Under normal, physiological conditions, swallowing involves moving a bite of a skylight, using the muscles that contract the throat, into the esophagus, where the peristaltic wave of the musculature of this organ then moves the skylights deeper into the stomach. At this time, the glottis, the upper part of the respiratory tract, is closed so that the skylights do not enter it and cause irritation leading to inflammation. With the section from the canisters to the lower parts of the gastrointestinal tract preserved and difficulties in swallowing occurring despite this, inflammation is not uncommon. The most common causes of problems include lack of saliva and lack of properly functioning throat muscles. These conditions can also occur together, increasing the swallowing problem and making treatment more difficult. Oliver
