Question

While observing cardiac muscle under a microscope for the first time, jennifer noticed lines running perpendicular to the direction of the muscle. these lines are called?

Answer 1

Hello!! Jennifer would have noticed lines call intercalated discs. Intercalated discs are connected to cardiomyocytes (muscle cells specialized in the heart), that word together as an organ. The function of the discs is to provide the heart with steady contractions. I hope I helped!! Have a great evening.

Answer 2

The correct answer is intercalated discs.

Step-by-step explanation:

Specific structural conformations located in between the myocardial cells of the heart are known as intercalated discs. They perform an essential function in connecting the cells of the cardiac muscle together and in conducting the signals between the cells.

The terminals of each cardiac muscle cell produce intercalated discs, where they come in contact with the adjacent cells of cardiac muscle.
