The gap junctions of intercalated discs provide a low-resistance pathway across the membranes of adjoining cardiac muscle fibers.

Question

Quizplus · Accepted Answer

Gap junctions in intercalated discs allow for the free flow of ions and small molecules between adjoining cardiac muscle fibers, resulting in an efficient and coordinated contraction of the heart. This low-resistance pathway is critical for proper electrical conduction and synchronization of the myocardium.
