Vedclass · Answer

(D) The heartbeat is myogenic in nature. The sequence of conduction is as follows:$1$. The impulse originates in the $SA$ (Sino-Atrial) node,which acts as the pacemaker.$2$. From the $SA$ node,the impulse travels to the $AV$ (Atrio-Ventricular) node.$3$. From the $AV$ node,it passes through the Bundle of $His$ (Atrioventricular bundle).$4$. Finally,it spreads through the Purkinje fibers to the ventricular musculature,causing contraction.Thus,the correct sequence is: $SA$ node $\rightarrow$ $AV$ node $\rightarrow$ Bundle of $His$ $\rightarrow$ Purkinje fibers.
