The _____ conducts action potentials down the atrioventricular septum.
A) Bachmann bundle
B) bundle of His
C) sinoatrial node
D) atrioventricular node

Question

Quizplus · Accepted Answer

The bundle of His conducts action potentials down the atrioventricular septum, separating into the left and right bundle branches to continue the signal down to the Purkinje fibers and into the ventricles. The Bachmann bundle conducts action potentials between the two atria, while the sinoatrial node generates the initial action potential and the atrioventricular node delays the signal to allow for proper atrial contraction before ventricular contraction.
