Figure 13. Histology underlying grossly smooth surface textures in transverse section. A, single-layered fibrolamellar cortex (DMNH 83592, tibiotarsus section c). B, three-layered cortex with a central fibrolamellar core and endosteal and periosteal lamellar bone (DMNH 83591, femur section e). M, medullary cavity; P, osteogenic layer of periosteum. Scale bars: A = 50 µm; B = 92 µm.
