Bundle of His is a network of
Options
A.Nerve fibres found throughout the heart
B.Muscle fibres distributed throughout the heart walls
C.Muscle fibres found only in the ventricle

Solution
-. A bundle of nodal fibres, atrio- ventricular bundle (AV bundle) continues from the AVN which passes through the atrio-ventricular septa to emerge on the top of the inter- ventricular 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.
