Intercalated discs, location of nuclei (whether central or peripheral), number of nuclei (whether mononuclear or multinuclear) and shape of cells (whether seperate or branched).

And what about light microscopy? How would we differentiate on it? And are the images usually shown on USMLE light or electron microscopy?

Both types of images are shown. We will use the same ID points, just on a different resolution.

You know what, in our med school we weren't taught histology in much detail so i'm also on the very basics. I am thinking of doing junqueira for it. I know it might be overkill for the steps. But seriously, how're we supposed to understand pathology without the basics of histology. I advise you to also do the same. Best of luck bro.
