The word "diaphragm" originates from Greek diaphragma, combining dia- (through) and phragma (fence or barrier). The term originally described a physical partition, later specialized in anatomy to denote the muscular structure dividing the chest and abdomen. The morpheme dia- implies "across" or "through," while phragm reflects the concept of a barrier, illustrating the diaphragm's role as a permeable yet separating layer.
