A certain role in Sh.'s education at. play also processes of a physiological resorption of a cartilaginous part of an intervertebral disk. By the end of the first year of life in the plate of a hyaline cartilage forming a support for a pulpozny kernel proliferative processes are noted. In the subsequent cellular elements in different departments of an intervertebral disk disappear. These changes lead to reduction of durability of an intervertebral disk that is the contributing factor for nodulation of Shmorl at children's and youthful age.
