Figure 7. Images and associated schematic diagrams of cleared and stained axial skeletons of chicken (Gallus gallus domesticus) embryos from developmental stages 43 to 45. A, stage 43 (day 17 of incubation) right lateral view. B, stage 43 right lateral schematic. C, stage 43 posterior schematic. D, stage 44 (day 18 of incubation) right lateral view. E, stage 44 right lateral schematic. F, stage 44 posterior schematic. G, stage 45 (day 19–20 of incubation) right lateral view. H, stage 45 right lateral schematic. I, stage 45 posterior schematic. Blue is cartilage and dark purple represents ossified tissue. Light grey is cartilage and black represents ossified tissue in the diagrams. Scale bar, 1 cm.
