Cardiac and skeletal muscle both appear striated (i.e., have stripes) when viewed microscopically. What is the feature/structure that helps to differentiate between these two types of muscle tissue? List and describe the two types of cell junctions that compose this distinctive feature/structure of cardiac muscle:

Intercalated discs are specialized cell junctions found between cardiac muscle cells. They play a crucial role in the coordinated contraction of cardiac muscle tissue. There are two types of cell junctions that compose the intercalated discs: Show more…

Skeletal and cardiac muscle are both types of striated muscle. You have been given one type of each sample, but the identifying labels have come off. You know that these muscles have some similarities and some differences in terms of their rate of depolarization, rate of repolarization, and length of action potential. Which of these features would not be useful in identifying the two types of muscle? Which of these features will you use to correctly label the samples? Explain what you would expect to see for skeletal and cardiac muscles for each feature that you use.
