Now, the intermediate filament is composed predominantly of two types of proteins. We have Desmond as well as a protein known as vimentin. Now, we also have these regions we call the dense bodies, which are shown with these brown dots. So the green portion are the intermediate filaments, the red portion are the thick filaments, the purple portion is a thin filament. And these brown regions are called dense bodies. And dense bodies are composed of a protein known as alpha Actinine.
