What are the Sulcuses of the heart?
The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart that separates the atria from the ventricles.
What is the function of the coronary sulcus?
The coronary sulcus is circumferential and separates the atria from the ventricles. The anterior and posterior interventricular sulci or grooves separate the ventricles.
What runs in the sulci of the heart?
The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein.
Which coronary artery is most commonly occluded?
The LAD artery is the most commonly occluded of the coronary arteries. It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system.
What is Infundibular septum?
The infundibular septum separates the right and left ventricular outflow tracts. On the right side, it is bordered by the line from the membranous septum to the papillary muscle of the conus inferiorly and the semilunar valves superiorly. The right side of the infundibular septum is more extensive.
What are sulci?
A sulcus (plural: sulci) is another name for a groove in the cerebral cortex. Each gyrus is surrounded by sulci and together, the gyri and sulci help to increase the surface area of the cerebral cortex and form brain divisions.
What is the definition of a sulcus?
Definition of sulcus : furrow, groove especially : a shallow furrow on the surface of the brain separating adjacent convolutions.
How do the coronary arteries relate to the atrioventricular sulcus?
One, the atrioventricular groove, is along the line where the right atrium and the right ventricle meet; it contains a branch of the right coronary artery (the coronary arteries deliver blood to the heart muscle).

Which coronary artery is called the Widowmaker?
A widowmaker is an informal term for a heart attack that involves 100 percent blockage in the left anterior descending (LAD) artery, says Stanley Chetcuti, M.D., an interventional cardiologist at the University of Michigan Frankel Cardiovascular Center.
What is the Septomarginal Trabecula?
The septomarginal trabecula is a constant element of the anatomy of the human heart, which connects the interventricular septum and the anterior wall of the right ventricle.
