Question

The myocardium (cardiac muscle tissue) undergoes a significant amount of physical stress due to its contractions. You would expect to see relatively large numbers of which of the following embedded within their plasma membrane?

Answer 1

Answer: D) desmosomes

Options: A) glycolipids B) transport proteins C) tight junctions D) desmosomes

Explanation:  Desmosome is a structure found in cells and has a strong adhesive force, helping cells to bind to other cells and form a sturdy structure. Because the myocardium goes through significant physical activity, desmosomes are necessary in the tissue cells to provide a powerful network between the cells that can withstand more activity than the cells of some other tissues that are not as prone to wear and tear.  They are also found in the epidermis.
