Detailed explanation-1: -The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart at the base of right auricle that separates the atria from the ventricles.
Detailed explanation-2: -The interventricular septum is located between the right and left ventricles of the heart. It runs between the interventricular grooves, which are the furrows on the anterior and posterior surfaces of the heart that also mark the boundary between the left and right ventricles.
Detailed explanation-3: -The interatrial groove is covered anteriorly by the ascending aorta and the main pulmonary artery. The interatrial groove is visible to the right of the heart as a fatty line between the superior vena cava and right superior pulmonary vein.
