Artery: Sinoatrial nodal artery
Low magnification micrograph of a sinoatrial node (central on image), which surroundings the sinuatrial nodal artery (on lumen in the image). H&E stain.
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	ramus nodi sinuatrialis arteriae coronariae dextrae

The sinoatrial nodal artery is an artery of the heart which supplies the sinoatrial node, and usually arises from either the right coronary artery or (less frequently) the circumflex branch of left coronary artery.
