Anterolateral Wall of Right Ventricle

Description

The heart wall windows follow the standard cuts that are made in anatomy dissections to visualize the internal structures and features of the atria and ventricles.

The anterolateral wall of the right ventricle illustrates cuts that are made from the base of the pulmonary trunk. It passes across the anterior wall of the right ventricle, about 1 cm below the coronary sulcus, to the inferior border of the heart. This window is also cut a few centimeters to the right of the anterior interventricular sulcus, along the interventricular septum.

The structures visible when the wall is reflected include:

- the smooth-walled outflow tract called the conus arteriosus (or infundibulum);

- a rough-walled portion formed from the ridged trabeculae carneae (or course apical trabeculations);

- septomarginal trabecula (or moderator band);

- papillary muscles, chordae tendineae (or tendinous cords);

- three leaflets of the right atrioventricular valve (or tricuspid valve);

- three semilunar leaflets of the pulmonary valve.
