[Tendinous fibers in the periosteum and bone]

The relation of muscles and bony skeleton studied in the work demonstrates a rather complex mechanism of connections existing between tendinous elements and periosteum and bone. Investigation on fixation of muscular tendons to the skeleton has demonstrated that in some cases tendinous filaments plait into the periosteum and terminate in it, while in other cases not all the tendinous filaments terminate at the level of the periosteum, but some of them penetrate into the bone. Thus, it has been demonstrated for the first time that tendinous filaments penetrate into the compact substance of the bone.
