Question

The atrio-ventricular node is situated

• A. Near the bicuspid valve
• B. In between the atrium
• C. At the base of inter-auricular septum
• D. In the interventricular septum

Answer 1

The correct option is C At the base of inter-auricular septum

The heart beat originates at SA node and passes to the AV node which finally conducts it to the bundle of His. The AV node is placed between the atria and the ventricles of the heart, specifically in the posteroinferior region of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles.

So, the correct answer is option C.
