Internal: happens on the inside.
It depends what “internal detail” do you want, but if it’s a character’s internal details it basically has to do with their thoughts, feelings, traits and what they’ve been through or experienced.
If you mean the internal detail of an object, like a house, it has to do with the number of rooms in the house, the measures, etc.
You need to include the lines shown in whatever your reading
You should cite all sources from which you get outside information. For example, if I'm writing an essay about cats, and I know that cats are fluffy, I can write that down with no need for citation. However, if I don't know that cats are felines until I read a Wikipedia page about them, then I need to site that page.
