Atrioventricular nodal branch

From Wikipedia, the free encyclopedia

Artery: Atrioventricular nodal branch

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 AVN = atrioventricular nodal VEINS: SCV = small cardiac ACV = anterior cardiac AIV/GCV = great cardiac MCV = middle cardiac CS = coronary sinus
Latin	Ramus nodi atrioventricularis

The atrioventricular nodal branch most frequently arises as a distal branch from the right coronary artery, but occasionally the atrioventricular node receives blood from the circumflex branch of the left coronary artery.
