Human diaphragm anatomy. Drawing of a normal human diaphragm in transverse section, viewed from below (i.e., from within the abdominal cavity); after Gray [51]. Anterior-posterior orientation of all diaphragm images within this report follows the same layout that is depicted here; left-right orientation is also maintained except for Figure 2, which is viewed from the chest cavity (i.e. viewed from above) and hence is left-right reversed.
