Improper formation of thi
Improper formation of this organ's posterolateral foramina can lead to a Bochdalek hernia, while a rarer disorder consists of a hernia through this organ's foramina of Morgagni. This organ is connected to the inferior parietal pleura, and the size of its zone of apposition can be changed through abdominal pressure. This organ is innervated by the phrenic nerve, whose irritation may cause involuntary spasms known as hiccups. This muscle increases the volume of the thoracic cavity to lower alveolar pressure. For 10 points, name this sheet of skeletal muscle at the bottom of the rib cage, whose contraction draws air into the lungs.
