Which component of intercalated discs provides strong mechanical attachment between cardiac cells?
Show answer and explanation
Correct answer: Desmosomes
Desmosomes anchor adjacent cardiac cells together and prevent them from separating during contraction. This strong mechanical connection is essential for the heart’s pumping function.
