Atrial branches of coronary arteries

Artery: Atrial branches of coronary arteries

Sternocostal surface of heart.

ARTERIES: RCA = right coronary AB = atrial branches SANB = sinuatrial nodal RMA = right marginal LCA = left coronary CB = circumflex branch LAD/AIB = anterior interventricular LMA = left marginal PIA/PDA = posterior descending MARG = left marginal AVN = atrioventricular nodal VEINS: SCV = small cardiac ACV = anterior cardiac AIV/GCV = great cardiac MCV = middle cardiac CS = coronary sinus
Latin	rami atriales arteriae coronariae dextrae

Although named for the right coronary artery in terminologia anatomica, a portion of the blood supply to the atria derives from the Circumflex branch of left coronary artery.

v • d • e List of arteries of torso - chest
Pulmonary / coronary	right coronary: SA nodal - AV nodal - atrial - right marginal - posterior interventricular left coronary: anterior interventricular - left circumflex - left marginal
Ascending aorta	aortic arch - brachiocephalic (thyreoidea ima) - common carotid
Subclavian	internal thoracic: anterior intercostal - thymic - pericardiacophrenic - terminal (musculophrenic, superior epigastric) costocervical trunk: highest intercostal (posterior intercostal 1-2) - deep cervical
Descending / thoracic aorta	visceral: bronchial - esophageal - mediastinal parietal: posterior intercostal 3-11 - subcostal - superior phrenic
