Question

Which of the following type of cell junction make up an intercalated disc?

• A. Fascia adherens
• B. Desmosomes
• C. Gap junctions
• D. All of the above

Answer 1

The correct option is D All of the above

Cardiac cells are connected to each other by intercalated discs. Cardiac muscle cells have three distinct types of intercellular junctions, namely gap junctions, desmosomes, and fascia adherens. All these junctions are located in the intercalated disc. Hence, all these cell junction make up an intercalated disc of cardiac cells.

Thus, the correct answer is 'All of the above.'
