A)Interatrial bundles
B)Atrioventricular node
C)Sinoatrial node
D)Purkinje fibers
E)Bundles of His
F)Internodal bundles

Question

Quizplus · Accepted Answer

The atrioventricular node is the structure through which conduction moves most slowly, allowing time for the atria to contract before the ventricles.

Answer: D
 The Purkinje fibers are responsible for spreading the electrical impulses quickly through the ventricular muscle, leading to the contraction of the ventricles.

Answer: C
 The sinoatrial node is the natural pacemaker of the heart, initiating the electrical impulses that lead to the contraction of the heart muscle.

Answer: A and F
 The interatrial and internodal bundles help to spread the electrical impulses through the atria, allowing for coordinated contractions. The bundles of His are part of the pathway that connects the atria to the ventricles.
