The Bundle of His is also known as which structure?

• A. Atrioventricular Bundle
• B. Sinoatrial Node
• C. Purkinje System
• D. Interventricular Septum

Answer: (A)

The Bundle of His is the atrioventricular bundle, a key part of the heart’s electrical conduction system that carries impulses from the AV node down into the ventricles via the bundle branches. This pathway coordinates the timing of ventricular contraction after atrial depolarization, and it travels through the upper portion of the interventricular septum. The sinoatrial node is the primary pacemaker in the right atrium, not the AV bundle; the Purkinje system is a separate network that distributes impulses within the ventricles after they travel through the bundle branches; and the interventricular septum is the wall between the ventricles, where the AV bundle runs but is not itself the bundle.
