Identify the correct path of the cardiac conduction system.

Question

Quizplus · Accepted Answer

The conduction system process of excitation and contraction originates in the sinoatrial (SA)node,located in the area where the superior vena cava (SVC)meets the right atrium.The impulse spreads to the atria through intermodal pathways and travels to the AV junction (which contains the AV node)located medial to the entrance of the coronary sinus in the right atrium,close to the tricuspid valve.From the AV junction,the impulse spreads to the bundle of His,which extends down the right side of the interventricular septum.The bundle of His divides into the right and left bundle branches,which terminate in a network of fibers called the Purkinje system.Purkinje fibers are spread throughout the inner surface of both ventricles and the papillary muscles,which when stimulated produce contraction of the heart muscle.
