The coronary sulcus is the groove that separates the atria from the ventricles. It can also be called the coronary groove or AV groove.
No the coronary sulcus does not contain fat. The coronary sulcus is a groove or depression on the surface of the heart located between the atria and ventricles and is lined with connective tissue.
The function of the coronary sulcus is to ultimately transfer blood between the cardiac muscles. The coronary sulcus is located between the ventricles and the atria. Reference: medical-dictionary.thefreedictionary.com
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 atria of the heart are separated from the ventricles by an area called coronary groove (sulcus). This contains the trunks of the coronary arteries which bring oxygenated blood to the heart muscles. On the back surface of the heart, the coronary sulcus contains the coronary sinus which receives venous blood from the heart muscles.
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.
coronary sulcus
The coronary sinus runs in the posterior coronary sulcus. In the anterior coronary sulci the stems of the coronary artery run. The circumflex branch of the left and the extension of the right coronary artery that becomes the posterior descending artery run around the coronary sulcus from front to back
The sulcus in the heart refers to the grooves or depressions on the surface of the heart that separate its various chambers. These grooves, such as the coronary sulcus and interventricular sulci, serve to delineate the atria from the ventricles and the right from the left ventricles, respectively. Additionally, they provide pathways for blood vessels and coronary arteries that supply the heart muscle with oxygen and nutrients. Overall, the sulci play a crucial role in the structural organization and function of the heart.
Circumflex Branch
the right interventricular sulcus I think it is atrioventricular sulus
Coronary sulcus
simple it is an artery
