[Structure of the osteon lamella].
The structure of osseous laminas of osteons was studied by methods of translucent and rastral electron microscopy. All laminas were shown to consist of collagenous fibrils and crystals of hydroxyapatite. The collagenous fibrils in the lamina are united into interwining bundles. The adjacent osseous laminas are different in orientation of fibrils and bundles in relation to the axis of the Haversian canal. The laminas are bound by bundles and solitary fibrils passing from one lamina into the other. In decalcificated sections of laminas of osteons have different relief. The laminas with longitudinally disposed fibrils project over the laminas with transversely disposed fibrils.
