Question

question
intercalated discs are specialized cell - to - cell junctions that involve which of the following?
answer
all of the listed responses are correct.
allows cardiac muscle cells to be connected by gap junctions
locks two muscle cells together while helping maintain a three - dimensional structure of tissue
aids the muscle cells in pulling together with maximum efficiency, by tying the myofibrils of adjacent cells together

Explanation:

Intercalated discs are found in cardiac muscle tissue. They have gap junctions (allowing communication between cells), desmosomes (locking cells together and maintaining tissue structure), and help in efficient muscle contraction by connecting myofibrils. So all the listed functions are correct.

Answer:

All of the listed responses are correct.
