Chapter 7: Organizing the Body

“Spatial ordering is also very useful when it comes to showing parts and their relationships. Let’s say, for example, that you’re a biology major and want to share some of the basics of cellular structure and function with your classmates. Again, you’re probably going to want a really detailed visual aid to do this (and some great analogies to reduce the complexity), but in thinking about how best to organize the speech, it seems logical to move from the outer cell wall (the cellular membrane) inward to the cytoplasm and then to the nuclear membrane and finally to the nucleolus. Sure, the cell functions as a unified organism, but for the sake of your speech, you need to divide the cell into its key components. But that division allows us to learn about the important parts and how each part, in turn, functions within the larger whole.”
