Analogies are often used to help make concepts easier to understand. Trisha wants to write an analogy to help her remember the difference between the axial skeleton and the appendicular skeleton. Which is the best analogy?

The axial skeleton forms the body's central axis, including the skull, spine, and rib cage. The appendicular skeleton includes the limbs and the bones that attach them to the central skeleton. A swing set's frame is its central supporting structure, while its swings are attached parts, so the frame-and-swings analogy fits best.
