Bundle of His is a network of
-
- nerve fibres found throughout the heart
- muscle fibres distributed throughout the heart walls
- muscle fibres found only in the ventricle wall
- nerve fibres distributed in ventricles

The atrioventricular bundle (AV bundle), on entering the ventricles splits into right and left branches. These branches then enter the heart muscles. They branch extensively and are called Purkinje fibres. They conduct the cardiac impulse to the ventricular wall.
