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

Question

Quizplus · Accepted Answer

The cardiac conduction system is a network of specialized cardiac muscle fibers that provide a path for each cycle of cardiac excitation to progress through the heart. These fibers include the SA node, AV node, bundle of His, and Purkinje fibers, which coordinate the contraction of the heart and maintain its rhythm. The other options (A, B, C, and E) are not directly related to the cardiac conduction system.
