Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The conduction system flows from the SA Node to the AV node. It then must go the ventricles through the fibrous skeleton. What is the name of the only branch that runs through the fibrous skeleton?

A	RIght Bundle Branch
B	Purkinje Fibers
C	Bundle of His
D	Bachmann’s Bundle

Explanation:

Detailed explanation-1: -Next, the signal travels to the AV node, through the bundle of HIS, down the bundle branches, and through the Purkinje fibers, causing the ventricles to contract. This signal creates an electrical current that can be seen on a graph called an electrocardiogram, or EKG.

Detailed explanation-2: -The SA node is in the upper part of your heart’s right atrium. It is at the edge of your atrium near your superior vena cava (vein that brings oxygen-poor blood from your body to your heart). Your autonomic nervous system controls how fast or slowly your SA node sends electrical signals.

Detailed explanation-3: -The atrioventricular (AV) node is a small structure in the heart, located in the Koch triangle, [1] near the coronary sinus on the interatrial septum.
