$E-C-A-D-B$

Vedclass · Answer

(D) The correct answer is option $D$ $(E-C-A-D-B)$.The conduction system of the heart follows a specific pathway to ensure coordinated contraction:$1$. The action potential originates at the $SA$ node $(E)$.$2$. It travels to the $AV$ node $(C)$.$3$. From the $AV$ node,it passes to the $AV$ bundle $(A)$.$4$. The $AV$ bundle divides into right and left bundle branches $(D)$.$5$. Finally,the impulse spreads through the Purkinje fibres $(B)$ to the ventricular myocardium.

Following are the stages of the pathway for the conduction of an action potential through the heart:
$A.$ $AV$ bundle
$B.$ Purkinje fibres
$C.$ $AV$ node
$D.$ Bundle branches
$E.$ $SA$ node
Choose the correct sequence of the pathway from the options given below:
