(Abstract).
The question of the movement of the palatine plates to this day is still the subject of lively discussion, which, however, has not yet led to a definite solution. The reason for this was a preparation of a pig embryo, 3 ml long, described by Dursu, in which one palatal plate was located next to the tongue, while the other lay on top of the tongue. Dursy thought this embryo was apparently pathological. In 1901. a second such case was published by His'om, suggesting that this embryo was in a normal physiological movement. His'a observation prompted many researchers to study this issue.
