Illustration of the coronary arteries
This image displays the anatomical location of the coronary arteries from a ventral and dorsal view. The left and right coronary arteries arise from the aortic sinus and run along the corresponding coronary sinuses on the caudal side of the heart. The majority of the population have right-dominant coronary artery circulation, with the RCA supplying the interventricular septum (Rr. interventriculares septales) and the AV node (R. nodi atrioventricularis).
Branches of the right coronary artery supply the sinoatrial node, the right atrium and ventricle, the atrioventricular node, approx. ⅓ of the interventricular septum, and a small part of the inferior surface of the left ventricle.
Branches of the left coronary artery supply the left atrium and ventricle, the anterior aspects of both ventricles, the cardiac apex, and ⅔ of the interventricular septum.
Cardiac conduction pathway
The subepicardial sinus node generates electrical impulses, which then travel through the walls of the atria to the subendocardial atrioventricular node. After a short delay in the atrioventricular node, the impulses pass through the bundle of His (situated in the membranous part of interventricular septum) to the Tawara branches. These then terminate in numerous small fibers (Purkinje fibers), which activate the heart muscle cells of the chambers and thus initiate cardiac contraction.
