FIG. 4. Completion of a linear heart tube (stage 32). Transverse sections demonstrate that by this stage, the myocardium has formed a
complete tube surrounding the endocardium in all but the most anterior region (see Fig. 3 legend for labelling details). The most posterior
sections show bifurcation of the endocardial tube into the sinus venosa (sv), dorsal to the liver primordium (liv). 3D models (dorsal view)
show the aortic sac (as) at the anterior end of the endocardial tube, as well as the ventral aorta and first aortic arch (aa). (For clarity, the dorsal
mesocardium and pericardial roof (grey) are omitted from dorsal and ventral views.) Image published in: Mohun TJ et al. (2000) Copyright © 2000. Image reproduced with permission of the Publisher, Elsevier B. V. Larger Image Printer Friendly View |
