Q. The cardiac impulse is initiated and conducted further upto ventricle. The correct sequence of conduction of impulse is

Body Fluids and Circulation

Solution:

The nerve impulses produced by the SA node travel to the AV node and cause the initiation of the articular depolarization. From here, the impulse travels to the AV bundle and then to the Purkinje fibres.
Thus, the correct answer is 'SA Node, AV node, AV Bundle, Purkinje fibre.'
