Which is one of the functional characteristics of cardiac myocytes that makes them adapted for the hard and continuous work they do?

Question

Quizplus · Accepted Answer

Intercalated discs provide mechanical integrity and help propagate electrical signals efficiently between adjacent cardiac myocytes. This enables the heart to maintain a strong and coordinated contraction even under continuous workload. Additionally, options A, C, and D are all incorrect. Each cardiac myocyte is not electrically independent since neighboring cells influence each other via intercalated discs. Excitation spreads not only through the specialized conduction system, but also through the intercalated discs, allowing for rapid and synchronized contraction of the heart. Finally, cardiac myocytes rely on various ion channels, including Ca2+ channels, for the creation of action potentials.
