I believe it is the same as the coronary sulcus, or at least the coronary sulcus is one of the two AV sulci. If i am correct than it is the groove on the outside of heart, in which, the circumflex artery lies.
The atrioventricular sulcus or groove is where the right coronary artery lies. It is between the right atrium and the right ventricle.
the right interventricular sulcus I think it is atrioventricular sulus
Coronary sulcus
The Coronary Sinus
Anterior and posterior interventricular/longitudinal sulci (singular sulcus).
The cardiac vessel located in the coronary sulcus that primarily contains deoxygenated blood is the coronary sinus. It collects deoxygenated blood from the heart muscle (myocardium) through several cardiac veins and drains into the right atrium. The coronary sulcus, also known as the atrioventricular groove, encircles the heart and separates the atria from the ventricles.
The coronary sulcus, also known as the atrioventricular groove, is a groove on the surface of the heart that marks the boundary between the atria and ventricles. It contains the main coronary arteries and helps supply blood to the heart muscle.
The answer is sulcus.
Sulci is the plural of sulcus
Promachoteuthis sulcus was created in 2007.
The Sullen Sulcus was created in 2002.
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.
