What component of the cardiac conduction system distributes electrical signals through the papillary muscles directly?

Question

Quizplus · Accepted Answer

Purkinje fibers are specialized cardiac muscle fibers that distribute electrical signals directly through the papillary muscles, allowing for coordinated and synchronized ventricular contractions. The other components listed (AV nodes, AV bundle, and bundle of His) are involved in the propagation of electrical signals through the heart, but do not directly distribute signals to the papillary muscles.
