Cardiac muscle cells are connected by special junctions called intercalated discs.Intercalated discs provide strength between cells of tissues which exhibit high mechanical stress,strong flexible connections between tissue cells,and electrical excitability between the cells.Using this information,which junctions are present in intercalated discs?
A)Tight,plasmodesmata,and adherens
B)Tight,plasmodesmata,and desmosomes
C)Gap,adherens,and desmosomes
D)Gap,desmosomes,and hemidesmosomes
E)Adherens,tight,and gap

Question

Quizplus · Accepted Answer

Intercalated discs contain gap junctions for electrical excitability and communication, adherens junctions for strong mechanical attachments, and desmosomes for added strength and flexibility, allowing cardiac muscle cells to work together efficiently during contractions.
