A) Atrioventricular node, sinoatrial node, Purkinje fibers, bundle of His
B) Sinoatrial node, atrioventricular node, bundle of His, Purkinje fibers
C) Bundle of His, sinoatrial node, atrioventricular node, Purkinje fibers
D) Purkinje fibers, sinoatrial node, atrioventricular node, bundle of His

Question

Quizplus · Accepted Answer

The correct sequence for the conduction of cardiac action potentials is SA node (located in the right atrium), AV node (located in the interatrial septum), bundle of His (located in the interventricular septum), and Purkinje fibers (located throughout the ventricular myocardium). Option B has the correct sequence.
