Place the components of the conducting system of the heart in the proper sequence in which they are activated. Some terms may be unfamiliar. Note that the term syncytium, pronounced "sin-sish-eum," describes an interconnected network of cardiac muscle cells. Junctional fibers lead directly to the AV node. Subendocardiac conducting network AV bundle Ventricular myocardium Bundle branches SA node AV node

Step 1
It initiates the electrical impulse that causes the heart to beat. This is the first component in the sequence. Step 2: From the SA node, the electrical impulse travels through the atrial myocardium (the muscle tissue of the atria) to the AV node Show more…
