At the AV node of the conduction system, the action potential is
A) rapidly advanced due to the cells being large and well connected by gap junctions.
B) rapidly advanced due to the cells being small and well insulated by myelin.
C) delayed due to the cells being small and having few gap junctions.
D) delayed due to the cells being large and having many leakage channels.

Question

Quizplus · Accepted Answer

The action potential is delayed at the AV node because the cells are small and have fewer gap junctions, which slows down the conduction of electrical impulses.
