Which network of specialized cardiac muscle fibers provides a path for each cycle of cardiac excitation to progress through the heart?

Question

Quizplus · Accepted Answer

The cardiac conduction system is a specialized network of cardiac muscle fibers that provides the path for the cardiac excitation to progress through the heart. It starts at the sinoatrial (SA) node in the right atrium, progresses through the atrioventricular (AV) node, the bundle of His, the bundle branches, and the Purkinje fibers, eventually reaching the ventricular muscle fibers and causing their contraction. The other options listed, such as systemic circuit, intercalated discs, and cardiovascular center, are not directly related to the specialized cardiac muscle fibers that make up the cardiac conduction system.
