Place the following structures of the electrical conducting system of the heart in the correct order from the beginning where the depolarization is initiated in the autorhythmic cells. Note: this question is graded as all or nothing for the correct order: 1. Sinoatrial (SA) node 2. Internodal pathway 3. Atrioventricular (AV) node 4. Atrioventricular (AV) bundle (bundle of His) 5. Left and right bundle branches 6. Purkinje fibers
Bryan V.
Which of the following is the correct sequence of a cardiac impulse? (A) SA node $\rightarrow$ AV node $\rightarrow$ Purkinje fibers $\rightarrow$ bundle of His $\rightarrow$ ventricles (B) AV node $\rightarrow$ bundle of His $\rightarrow$ Purkinje fibers $\rightarrow$ ventricles $\rightarrow$ atria (C) SA node $\rightarrow$ atria $\rightarrow A V$ node $\rightarrow$ bundle of His $\rightarrow$ Purkinje fibers $\rightarrow$ ventricles (D) SA node $\rightarrow$ AV node $\rightarrow$ atria $\rightarrow$ bundle of His $\rightarrow$ Purkinje fibers $\rightarrow$ ventricles
