Which of the following are components of the conduction system of the heart (choose all that apply)?
A) bicuspid valve
B) Purkinje Fibers
C) atrioventricular septum
D) atrioventricular node
E) Bundle of His/atrioventricular bundle
F) chordae tendinae
G) sinoatrial node
H) papillary muscles

Let’s dive into the heart’s conduction system! The conduction system includes specialized structures that help coordinate the heartbeat. The key players are the Purkinje Fibers (B), which rapidly distribute electrical impulses to the ventricles; the atrioventricular node (D), which acts as a gatekeeper between the atria and ventricles; the Bundle of His/atrioventricular bundle (E), which carries signals from the AV node to the ventricles; and the sinoatrial node (G), the pacemaker of the heart that initiates the heartbeat.

To put it all together, the heart’s conduction system ensures our ticker beats in harmony, keeping us on our toes! Common mistakes include confusing conduction components with heart valves or muscle structures, like the bicuspid valve (A) or chordae tendinae (F), which are involved in heart function but not in the conduction process. So, it’s easy to get tangled up if you mix up their roles!
