Which bundle branch transmits impulses to the myocardium of the right ventricle?

• A. Left bundle branch
• B. Right bundle branch
• C. Septal fascicle
• D. Left anterior fascicle

Answer: (B)

The bundle branch responsible for transmitting impulses to the myocardium of the right ventricle is the right bundle branch. This structure is part of the cardiac conduction system and plays a crucial role in coordinating the timing of heartbeats. After impulses are generated in the sinoatrial (SA) node and travel through the atrioventricular (AV) node, they enter the bundle of His, where they then divide into the right and left bundle branches. The right bundle branch specifically extends into the right ventricle, allowing for effective contraction of the myocardium in that chamber. As it conducts electrical impulses, it ensures that the right ventricle contracts in a synchronized manner with the left ventricle, which is vital for efficient pumping of blood to the lungs for oxygenation. This coordination is essential for maintaining proper cardiovascular function and is why the right bundle branch is specifically associated with transmitting impulses to the myocardium of the right ventricle.
