Quizplus · Accepted Answer

The internodal pathways are a network of fibers that carry the electrical signals from the sinoatrial (SA) node to the atrioventricular (AV) node. These pathways are located in the atria of the heart and help propagate the electrical impulses through the heart. The other structures listed (bundle branches, Purkinje fibers, chordae tendineae) are important for different aspects of the heart's function, but they do not carry electrical signals between the SA and AV nodes.
