What structural component of cardiac muscle cells allows for electrical current to flow from cell to cell?
A)tight junctions
B)gap junctions
C)adhesion junction

Question

Quizplus · Accepted Answer

Gap junctions are specialized protein channels that allow for direct communication and electrical coupling between adjacent cardiac muscle cells, thereby allowing impulses to spread rapidly and efficiently through the heart. Tight junctions and adhesion junctions are types of cell junctions that serve mainly to connect and anchor cells together, but they do not allow for significant ion flow or electrical communication between cells.
