It receives the impulse to contract from the sinoatrial node, via the atria, and transmits it through the atrioventricular bundle to the ventricles.Specialized cardiac muscle fibers in the lower interatrial septum that receive impulses from the sinoatrial node and transmit them to the bundle of His.A highly specialized region within the heart muscle that conducts electrical impulses.The atrioventricular node is a small cluster of specialized muscle cells located in the right atrium, the upper chamber of the heart. It serves as a relay station for electrical impulses originating from the sinoatrial node, which functions as the heart's natural pacemaker. These electrical signals travel through the atrioventricular node and along conducting fibers to the ventricles, the lower chambers of the heart. As a result, the ventricles contract and effectively pump blood throughout the body, sustaining circulation.A heart structure that helps regulate the coordinated rhythm of heartbeats, initiating the process in the atria and leading to ventricular contractions. It is also known as the auriculo-ventricular node.
