Given the following structures of the conduction system of the heart, arrange them in the order in which an action potential would pass through them. 1) AV node2) Atrioventricular bundle3) Bundle branches4) Purkinje fibersMultiple Choice1, 4, 2, 32, 1, 3, 41, 3, 2, 43, 1, 2, 41, 2, 3, 4

Which of the following structures are able to spontaneously generate an action potential?Multiple ChoiceThe atrioventricular bundleAll of the choices are correct.The sinoatrial node (SA Node)The atrioventricular node (AV Node)The right and left bundle branches

What is the correct sequence of components of the cardiac conduction system?Multiple ChoiceAV node → SA node → Purkinje fibers→ AV bundleSA node → AV node → AV bundle → Purkinje fibersAV node → AV bundle → Purkinje fibers → SA nodeSA node → Purkinje fibers → AV node → AV bundle

Conduction of impulses between the atria and the ventricles is channelled through the a. Annulus fibrosus b. AV node c. SA node d. Bundle of His

00. Which phase(s) of the action potential accounts for thegeneration and propagation of impulses by the heart withoutexternal stimulation?CABAll

Action potential generated at sino-atrial node passes from atria to ventricles
