What forms the central network of cardiac muscle cells?
Understand the Problem
The question is asking about the structural components that form the central network in cardiac muscle cells, specifically identifying which of the listed options correctly represents this feature.
Answer
The cardiac syncytium
The central network of cardiac muscle cells is referred to as the cardiac syncytium.
Answer for screen readers
The central network of cardiac muscle cells is referred to as the cardiac syncytium.
More Information
Cardiac syncytium refers to a network of cardiomyocytes interconnected by intercalated discs that allow for the coordinated contraction necessary for effective heart function. This connectivity ensures that the heart beats in a unified and rhythmic manner.
Tips
A common mistake could be confusing the syncytium with a simple collection of cardiac cells, rather than recognizing the importance of their interconnectedness.
