The term [coronary] comes from the Latin root [corona] meaning "crown", therefore [coronary] is used to denote a structure that surrounds another as a crown or a garland. In the heart, the coronary arteries and their branches form a crown that surrounds the heart at the level of the atrioventricular sulcus. There are two coronary arteries, the right coronary artery (RCA), and the left coronary arteryartery (*). The two main branches that arise from the left coronary artery are the circumflex artery (CFX) and the left anterior descending artery (LAD).
There can be interesting anatomical variations in the coronary arteries of the heart.
Although not in use anymore, the gastric arteries used to be called the "gastric coronaries" as the right and left gastric arteries and the right and left gastroepiploic arteries form a garland of arteries that surround the stomach. The term still does apply to the left gastric veins.
