The gnathic system in obese and diabetics. I (Basic relationship of function and form).
The authors pay complex attention to the research of the gnathic system, focused first of all to the mechanical interactions towards solid formations of the gnathic system. The results of their analysis show, that in the first cell already differentation to tensile functions of the membrane and compressive functions of its contents (cytoplasm) exists. In the osseous tissue the mechanical strain is also distributed to different substances, reacting differently to the mechanical stress according to their aggregate state--the liquid state secures an equal distribution of the developing compression, the collagens intercept and cushion the arising traction, and the mineral component the oriented compressions. Therefore, the bone tissue markedly differs from the inorganic homogenous solid substances, where the distribution of the mechanical strain is different. A detailed analysis shows that the form and structure of the bones is in accord with the course of the developing compressive strain and dependent on the mechanical consistency of the consumed food.
