The grooves in which the coronary arteries lies are known as?

The grooves in which the coronary arteries lie are known as coronary sulci or coronary grooves. These grooves separate the atria and ventricles and help to accommodate the coronary arteries that supply blood to the heart muscle. The major coronary sulci include the atrioventricular (AV) sulcus and the interventricular sulcus. These structures play a crucial role in the anatomical organization of the heart's vascular system.
