Fig. 3. Mouse E10.5 Developing Heart
The image shows a cut across the developing heart tube early on E10.5 in the developing mouse. This is equivalent to Carnegie stage 12 or Carnegie stage 13 in man, when the human embryo is almost 4 weeks old.
The atrial appendages are ballooning in parallel fashion (horizontal white arrows with black borders) from the atrial component of the initial heart tube, shown in the upper part of the frame. The atrioventricular (AV) canal at this early stage is supported by the inlet part of the ventricular loop, which is itself beginning to expand apically by the process of ballooning. Ballooning from the ventricular loop, however, occurs in serial fashion, so that the muscular ventricular septum (white star) is beginning to appear between the expanding ventricular apical components (downward pointing white arrows with black borders).
