Question

Quizplus · Accepted Answer

The interventricular sulci and coronary sulcus contain all of the above (fat, arteries, and veins). The interventricular sulci house the anterior interventricular artery (also known as the left anterior descending artery) and its branches, which supply blood to the front and side of the heart, as well as cardiac veins that drain blood from the myocardium. The coronary sulcus, also known as the atrioventricular groove, houses the right and left coronary arteries (which supply blood to the heart itself) and their accompanying cardiac veins. Both sulci also contain some adipose tissue.
