(a)
The heart is formed of cardiac muscles which have the property of excitability and conductivity. When the cardiac muscles are stimulated by a specific stimulus these got excited and initiate the waves (depolarization) of electric potential called cardiac impulse. Cardiac impulse is propagated through SA node AV node
Bundle of His
Purkinje fibres.
