Question

Quizplus · Accepted Answer

Purkinje fibers are the branches that are at the terminal ends of the bundles of His.

Answer: E
 Bundles of His are the initial portion of the conduction system that originates at the AV node and branches into the left and right bundle branches.

Answer: A
 Interatrial bundles are located in the interatrial septum and distribute impulses from the sinoatrial node to the left and right atrium.

Answer: B
 Atrioventricular node is located in the lower atrial septum and functions to delay and relay impulses from the atria to the ventricles.

Answer: C
 Sinoatrial node is located in the upper right atrium and functions as the heart's natural pacemaker by initiating the electrical impulses that stimulate cardiac contraction.

Answer: F
 Internodal bundles are located in the atrial walls and function to distribute impulses from the sinoatrial node to the atrioventricular node.
