    Question: 1 of 107Anatomy and physiology proctored exam (Ivy college)
    Which cardiac conduction system component follows the SA node?
    Explanation
    A. AV node: The impulse travels from the SA node through atrial pathways to the AV node next—this is the normal sequence. B. Bundle of His: Comes after the AV node, not immediately after the SA node. C. Purkinje fibers: Terminal conduction fibers in the ventricles; far downstream from the SA node. D. AV bundle: Another name for the Bundle of His, which still comes after the AV node.
