( a ) right bundle and left bundle, nodal fibres; right bundle and left bundle, purkinje fibres
( b ) left bundle and right bundle, AV bundle; left bundle and right bundle, purkinje fibres
( c ) right bundle and left bundle, purkinje fibres; right bundle and left bundle, bundle of His
( d ) right bundle and left bundle, nodal fibres; right bundle and left bundle, bundle of His

A specialised cardiac musculature called the nodal tissue is also distributed in the heart....... A bundle of nodal fibres, atrioventricular bundle (AV bundle) continues from the AVN which passes through the atrio-ventricular septa to emerge on the top of the interventricular septum and immediately divides into a right and left bundle. These branches give rise to minute fibres throughout the ventricular musculature of the respective sides and are called purkinje fibres. These fibres alongwith right and left bundles are known as bundle of His.
