Question

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

• A. S A Node, A V Node, Purkinje fiber, A V Bundle
• B. S A Node, Purkinje fiber, A V Node, A V Bundle
• C. S A Node, A V Node, A V Bundle, Purkinje fiber
• D. S A Node, Purkinje fiber, A V Bundle, A V Node

Answer 1

The correct option is C

S A Node, A V Node, A V Bundle, Purkinje fiber

The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to, and stimulate, the cardiac muscle (myocardium). The myocardium contracts after stimulation.
