Bundle of His is a network of
A
Muscle fibres distributed throughout the heart walls
B
Muscle fibres found only in the ventricle wall
C
Nerve fibres distributed in ventricles
D
Nerve fibres found throughout the heart
Answer
Muscle fibres found only in the ventricle wall
Explanation
Solution
Bundle of His is a network of cardiac muscle fibres found only in the ventricle wall. The bundle of His in continuation of the AV node gives off a left bundle branch at the top of the interventricular septum and continues as the right bundle branch. It is a part of conducting system along with other parts like SA node, intemodal atrial pathways, atrioventricular node, Purkinje system. SA node '>> Impulse '> Atrial pathways '>> AV node -> Bundle of His Purkinje system '> Ventricular muscle.
