Which feature allows cardiac muscle tissue to contract as a functional syncytium?
Show answer and explanation
Correct answer: Intercalated discs with gap junctions
Gap junctions within intercalated discs allow electrical impulses to pass quickly between cells. This synchronizes contraction across cardiac muscle tissue.
