And we'll talk more about this when we discuss the cardiovascular system and the heart. The final connection, the final intracellular junction that we want to discuss are desmosomes. So what exactly is a desmosome and what is the purpose of the desmosome connection? Well, they basically attach themselves to intermediate filaments found in the cytoplasm of the cell that are composed of a protein known as carotene. Now, they hold so Desmondomes hold two or more adjacent cells tightly together at a localized region. So on this diagram, for example, this is one Desmond, and this is the other Desmond.
