Figure 11. Transverse sections of immature long bones. A, single-layered fibrolamellar cortex (DMNH 83586, femur section c). B, active incorporation of channels at the surface of the fibrolamellar cortex (DMNH 83586, tibiotarsus section c). C, stratified fibrolamellar cortex (DMNH 83586, tibiotarsus section c). D, circularly orientated oblique channels in outer regions of fibrolamellar cortex (DMNH 83589, femur section d). B, blood vessel with erythrocytes; L, lymphatic vessel; M, medullary cavity; P, osteogenic layer of periosteum. The space within P is a preparation artefact. Scale bars: A, D = 230 µm; B = 50 µm; C = 92 µm.
