decidua

noun dɪˈsɪdjʊədəˈsɪdʒəwə

mass nounPhysiology

The thick layer of modified mucous membrane which lines the uterus during pregnancy and is shed with the afterbirth.
〔生理〕蜕膜
Example sentencesExamples
- One mechanism by which microorganisms might cause preterm labor is through ascension from the cervical/vaginal area and replication in the placenta, decidua and membranes.
- Ectopic decidua was found in 3% of the specimens and could be seen in both subserosal and plical areas, and was found only in postpartum patients.
- The tissue is sent to the laboratory where the fetal villi are dissected from the maternal decidua and either processed directly or cultured for chromosomal, DNA or biochemical analysis.
- Extreme care is used in inspecting the placenta and membranes in an effort to insure complete expression of the entire decidua.
- There were large amounts of polarizable foreign body material contained within the membranes and maternal decidua, without associated inflammation or tissue reaction.

Derivatives

decidual

adjective dɪˈsɪdjʊəldəˈsɪdʒuəl

Physiology

The thickened, hormonally charged decidual tissue is a fertile implantation site for the enlarging placenta and also acts as a barrier between the placental tissue and uterine muscle.
Example sentencesExamples
- The pathophysiologic events that trigger preterm birth are largely unknown but may include decidual hemorrhage, uterine overdistension, and hormonal changes possibly mediated by fetal or maternal stress.
- Microscopically, in deciduosis, the sheets of decidual cells are present within the connective tissue and do not usually affect its surface, as in the case of mesothelioma.
- Separate fragments of secretory endometrium with decidual stromal reaction and inactive glands were also seen.
- An endometrial biopsy performed 3 months prior to the current presentation showed ‘fetal part’ without decidual or chorionic villi.

Origin

Late 18th century: from modern Latin decidua (membrana), literally 'falling off (membrane)'.
