Question

Quizplus · Accepted Answer

Intercalated discs are specialized gap junctions found in cardiac muscle that allow for the conduction of contraction stimuli from one cardiocyte to the next. Tight junctions and desmosomes are also found in intercalated discs but serve different functions. Striations refer to the alternating light and dark bands observed on muscle fibers and are not specific to cardiac muscle.
