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

The atrial branches of right coronary artery derive from the right coronary artery and provide part of the blood supply to the right atrium and left atrium.

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
