Following are the stages of pathway for conduction of an action potential through the heart:A. AV bundleB. Purkinje fibresC. AV nodeD. Bundle branchesE. SA nodeChoose the correct sequence of pathway from the options given below:
To solve this problem, we need to determine the correct sequence of the conduction pathway of an action potential through the heart. Let's analyze each component:E. SA node: - The sinoatrial (SA) node is the natural pacemaker of the heart, initiating the action potential.C. AV node: - The atrioventricular (AV) node receives the impulse from the SA node and provides a delay to ensure the atria contract before the ventricles.A. AV bundle:
