What does a functional syncytium of cardiac muscles cells mean?

Question

Quizplus · Accepted Answer

A functional syncytium of cardiac muscle cells means that the cells work together as a unit both mechanically and electrically, allowing for coordinated contractions and efficient pumping of blood. This is due to the presence of intercalated discs that allow for rapid spread of electrical signals between cells, resulting in a synchronized contraction. While cardiac muscle cells are also striated and exhibit muscle tone, a short refractory period is not necessarily a defining characteristic of a functional syncytium.
