Which junction type within intercalated discs allows rapid electrical communication between cardiac cells?
Show answer and explanation
Correct answer: Gap junctions
Gap junctions allow ions and electrical impulses to pass directly between cardiac cells. This electrical coupling enables synchronized contraction of the heart muscle.
