Coronary sulcus

From Wikipedia, the free encyclopedia

Coronary sulcus
Sternocostal surface of heart. (Right coronary artery, which runs down coronary sulcus, is visible at left.)
Latin	sulcus coronarius
Gray's	subject #138 526

The atria of the heart are separated from the ventricles by the coronary sulcus (coronary groove, auriculoventricular groove, atrioventricular groove); this contains the trunks of the nutrient vessels of the heart, and is deficient in front, where it is crossed by the root of the pulmonary artery.
