The Inferior Boundary of the Thorax.—The diaphragm forms a muscular dome-shapedpartition which constitutes the inferior boundary of the thorax. The right side of the dome,which covers the liver, projects upward more markedly than does the left side. The centraltendon is flatter and has a more restricted range of motion during respiration (review the lumbar,costal, and sternal portions of the muscle with their origins). The structures passing through. The diaphragm and the inferior half of the pericardium seen from above. Formalin preparation (child). the diaphragm from above downward are: the descending aorta through the aortic opening;the esophagus and the pneumogastric nerves through the esophageal opening; the splanchnicnerves, from the sympathetic, between the crus mediale and the crus intermedium of the lum-bar portion; the sympathetic nerve itself between the crus intermedium and the crus lateraleof the lumbar portion; and the superior epigastric artery, from the internal mammary betweenthe sternal and costal portions (the so-called fissure of Larrey). The structures passing throughthe diaphragm from below upward are: the inferior vena cava (accompanied by a filament fromthe right phrenic nerve), through the foramen quadratum in the right side of the central tendon;the vena azygos major (on the right side) and the vena azygos minor (on the left side), accom- Left subil
