Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following represents the correct path for the transmission of an impulse during initiation of heart beat?
A
AV node, Bundle of His, SA node, Purkinje fibers, bundle branches
B
SA node, AV node, Bundle of His, bundle branches, Purkinje fibers
C
SA node, Bundle of His, AV node, Purkinje fibers, bundle branches
D
SA node, Bundle of His, bundle branches, Purkinje fibers, AV node
Explanation: 

Detailed explanation-1: -SA node generates impulse and afetr that it goes to AV node. From AV node impulse goes to Bundle of His and from there it goes to Purkinjee fibres and spreads all over the ventricle.

Detailed explanation-2: -The correct answer is E. SA node, AV node, bundle of His, Purkinje fibres. The signal is generated from the SA node (sinoatrial node), which is present in the upper corner of the right atrium. It generates impulse at a rate of 72 beats per minute.

Detailed explanation-3: -The sino-atrial (SA) node. The atrio-ventricular (AV) node. The bundle of His. The left and right bundle branches. The Purkinje fibres.
