What anatomical feature is formed by the branching of the AV Bundle of His?

The branching of the AV Bundle of His is crucial for the conduction system of the heart. When the Bundle of His branches, it divides into the right and left bundle branches, which extend along the interventricular septum. These bundle branches are responsible for transmitting electrical impulses throughout the ventricles, allowing for coordinated contraction and effective pumping of blood.

This branching occurs after the Bundle of His conducts signals from the atrioventricular node to the ventricles, ensuring that the signals reach both sides of the heart simultaneously. The right and left bundle branches then further divide into Purkinje fibers, which innervate the myocardial tissue and facilitate the contraction of the ventricles. Thus, the anatomical feature formed by the branching of the AV Bundle of His is specifically referred to as the bundle branches, underscoring their essential role in the heart's electrical conduction system.
