jejunum n.second division of the small intestine, late 14c., from Modern Latin noun use of Latin ieiunum, neuter of ieiunus "empty" (see jejune). Translating Greek nestis (Galen). So called because it typically is found empty during dissections, perhaps because it would tend to drain in a body laid on its back. updated on January 28, 2016 |
