Fig. 38. Mouse E11.5 Heart

The image shows a reconstructed episcopic dataset from a mouse embryo early during E11.5.

The reconstruction is viewed from the right side. The lumen of the outflow tract, and its continuation as the pharyngeal arch arteries, are shown in red. The right third, fourth, and sixth arch arteries are seen extending through the pharyngeal mesenchyme. They unite dorsally to form the dorsal aorta. The margins of the pericardial cavity mark the boundary between the distal component of the outflow tract and the aortic sac. By this stage, the myocardial walls have regressed minimally from the pericardial border, with the most distal walls of the outflow tract now formed by non-myocardial tissues. Note the cushions, derived from the cardiac jelly, which spiral through the intermediate and proximal part of the outflow tract. They end distally at the level of the regressing myocardial border. The so-called septal cushion is shown in yellow, with the parietal cushion colored green.

The reconstruction was made by Dr. Simon Bamforth, and is reproduced with his kind permission.
