Just to add on to this, the notes by the artists varied a lot too. Often the notes were just a hint at what's supposed to be happening in the panel. Sometimes they included suggested dialogue (varying from very brief hints to full sentences), especially if it's important for the context. But generally speaking, what appears on the final pages is very different than what appears in the notes, the notes were usually very unpolished or incomplete.

Pic is Roy Thomas's final dialogue/captions and not Stan's, but you can get some idea of what Ditko's panel scripts looked like in a couple cases.
