Early Heart and Primitive Heart Tube Folding Animation of the fusion of two endocardial tubes into a single primitive heart tube. Detailed descriptions of the movement of the bulbis cordis, primitive ventricle, primitive atrium, and sinus venosus. (approx. 2 minutes) Requires QuickTime plugin Overview of Heart Tube Folding and Early Heartbeat Brief summary of heart tube folding events, and demonstration of first heartbeats in the early heart. (approx. 20 seconds) Requires QuickTime plugin Interatrial Septum Development Detailed description of the formation of the interatrial septum, including formation of septum primum, septum secundum, and foramen ovale. (approx. 8 minutes) Requires QuickTime plugin Division of the Atrioventricular Canal Two animations describing how superior and inferior endocardial cushions divide the atrioventricular canal into left and right atrioventricular openings. The first animation depicts the anterior view of the heart. (approx. 3.5 minutes) The second animation shows a lateral view, seen from left side. (approx. 3 minutes) Requires QuickTime plugin Development of Aorta, Pulmonary Trunk, and Interventricular Septum Animation first illustrates development of muscular ventricular septum, then shows how the truncus arteriosus is subdivided into an aorta and pulmonary trunk and illustrates the development of the membranous part of the ventricular septum. (approx. 6 minutes) Requires QuickTime plugin Fetal vs. Postnatal Circulation Animation that compares fetal circulatory pattern with the postnatal circulatory pattern. Embryologic origin of postnatal circulatory structures is shown. Requires Macromedia Flash plugin Pericardium Development Animation that illustrates the development of the pericardium from two pleuropericardial folds. Also shows phrenic nerve placement. Requires Macromedia Flash plugin Aortic Arch Vessels Animation and description of the development of the aortic arch vessels, aortic sac, and descending aorta. Individual vessel development is illustrated. Requires Macromedia Flash plugin
