What serves as a structural support for the whole thoracic arrangement?

a well i don't really know the answer so please help me!!!!! I'm so confused. why can't they just tell us the answer?? GEESE

Sorry, Geese, Maybe they want you to dig it out of your text. Now, on to the initial question:

The whole thoracic arrangement (of a human) would be supported by the thoracic vertebrae, and those, in turn by the lumbar vertebrae which rest on the pelvis, connected to the femurs and then to the tibiae and fibulae which pass the load through the tarsals and metatarsals into your shoe. So the ultimate answer would have to be "The floor that you are standing on." but, you may want to break out that text and see if "thoracic vertebrae" doesn't satisfy that question.

That is the worng answer the answer is......It lets it diguests the thoracic first
