来自希腊语diaphragma,阻挡，障碍，dia-, 穿过，-phrag, 阻挡，词源同cataphract. 原指分开喉咙和腹腔之间的肌肉，后也用于指照机的光圈等。

diaphragm: diaphragm: [17] The etymological notion underlying diaphragm is of a sort of ‘fence’ or ‘partition’ within the body. It comes via late Latin diaphragma from Greek diáphragma. This in turn was a derivative of diaphrássein ‘divide off, barricade’, a compound verb formed from the intensive prefix dia- and phrássein ‘fence in, enclose’. Originally in Greek diáphragma was applied to other bodily partitions than that between the thorax and the abdomen – to the septum which divides the two nostrils, for instance.
diaphragm (n.): late 14c., from Late Latin diaphragma, from Greek diaphragma "partition, barrier, muscle which divides the thorax from the abdomen," from diaphrassein "to barricade," from dia- "across" (see dia-) + phrassein "to fence or hedge in." The native word is midriff. Meaning "contraceptive cap" is from 1933.
