Place the following structures of the electrical conducting system of the heart in the correct order from the beginning where the depolarization is initiated in the autorhythmic cells. Note: this question is graded as all or nothing for the correct order. left and right bundle branches Purkinje fibres internodal pathway atrioventricular node (AV) node atrioventricular (AV) bundle (bundle of His) sinoatrial (SA) node

00:01 Okay, in an advanced question, let's talk about the electrical conducting system of the heart.

00:04 Okay? if this is your heart and this is the right atrium, this is the right ventricle, this is the left atrium, and this is the left ventricle.

00:13 Here you're going to have the sinus or the sinoatrial node.

00:18 Okay, let's make it like this.

00:21 It's going to be the same atrial node.

00:24 From here, the electrical stimulus or conduction system is going to go to this space here.

00:32 Here, like about here, that is the atrial ventricular node.

00:42 Interventricular node.

00:43 Okay? then you're going to have that from this atrial ventricular node, oh, i'm sorry, this also, this is called the internodal pathway, because practically this is a pathway between these two nodes, the sine radical node and the ab node.

00:59 So then you're going to have that from the ab node, you're going to have the bundle of his.

01:05 Is going to be the bundle of this.

01:11 And then you're going to have the right and the left bundle branch.

01:17 It's going to be the right and this is going to be the left branch.

01:24 Okay.

01:25 This is the right branch.

01:29 And this is the left branch...
