About
The character 膈 is a phono-semantic compound. Its left radical 月 (flesh) places it in the domain of anatomy. The right component 鬲 (a tripod cauldron) provides the pronunciation "gé"; some scholars note that the cauldron's partitions may also symbolically reflect the body's internal division. The character specifically denotes the diaphragm, the sheet of muscle separating the thoracic and abdominal cavities. Its medical meaning has remained consistent from historical texts to modern anatomy, with no significant shift toward abstract usage.
