For intermediary anatomy students learning skeletal and muscle structure. In this lesson, you will learn what the diaphragm is, what it's made of, and how it functions. Action: Inspiration. It is the primary muscle that is active in inspiration. When the diaphragm relaxes, the air is mechanically pushed back out because the space becomes smaller. Because air will always move from the highest pressure area to the lowest pressure area. The diaphragm is a muscle. An insertion is where a muscle ends and typically moves during muscle action. SpasmsDuring a diaphragm muscle spasm, the diaphragm doesnt relax and curves back up during expiration. When it contracts, the diaphragm comes shortens and flattens. They also fire during expiration (although at a decrease rate) to exert a braking action on the diaphragm. The lumbar surface originates at four points on the back side of the body occurring at the first and second lumbar vertebrae.
