1. It supplies the posterior 1 / 3 of the interventricular septum. 2. Rupture of the interventricular septum will cause a ventricular septal defect. 3. Unlike other salamanders, an interventricular septum is present in the heart. 4. It is most commonly located in the interventricular septum or left resection. 5. The interatrial septum separates the atria and the interventricular septum separates the ventricles. 6. Normal Q waves, when present, represent depolarization of the interventricular septum. 7. It even features an interventricular sulcus, the crease dividing the left ventricle from right. 8. The primitive ventricle becomes divided by the septum inferius which develops into the interventricular septum. 9. It passes into the interventricular foramen, and is present at the top of the third ventricle. 10. There is also an anastomosis between the septal branches of the two coronary arteries in the interventricular septum.
