If you inhale and your belly moves outward on the inhale, well then that phrenic nerve is controlled. That's diaphragmatic breathing. You also have these muscles between your ribs or the intercostal muscles. And there's a separate set of nerves that allow those muscles to contract and for your rib cage to expand. When you're exerting yourself very hard, you tend to use both the inter costal muscles and your rib cage moving as well as your diaphragm in order to bring in oxygen and offload carbon dioxide.
