Tag: heart rate regulation

The heart’s ability to beat rhythmically depends on its specialized conduction system, a network that coordinates electrical impulses for efficient pumping. This anterior view of a frontal section diagram illustrates key components such as the sinoatrial node, internodal pathways, atrioventricular node, atrioventricular bundle, right bundle branch, left bundle branch, and Purkinje fibers, offering a clear view of how these structures regulate cardiac activity. Exploring this image provides a deeper understanding of the electrical framework that sustains circulation.
