| placental dysfunction syndrome | <syndrome> Foetal malnutrition and hypoxia resulting from impaired transfer of oxygen and various nutritive materials from mother to foetus. (05 Mar 2000) |
|---|---|
| placental dysmature | Immature development of the placenta so that normal function does not occur. (05 Mar 2000) |
| placental dystocia | Trouble delivering the placenta (the afterbirth). Dystocia comes from the greek dys meaning difficult, painful, disordered, abnormal + tokos meaning birth. (12 Dec 1998) |
| placental extracts | Extracts prepared from placental tissue; they may contain specific but uncharacterised factors or proteins with specific activities. (12 Dec 1998) |
| placental function tests | Methods used for the assessment of placental function. (12 Dec 1998) |
| placental growth hormone | human placental lactogen |
| placental hormones | Hormones produced by the placenta during pregnancy, including chorionic gonadotropin and substances having oestrogen, progestin, or adrenocorticoid activity. (12 Dec 1998) |
| placental insufficiency | Failure of the placenta to deliver an adequate supply of nutrients and oxygen to the foetus. (12 Dec 1998) |
| placental lactogen | <chemical> A polypeptide hormone secreted by the placenta that enters the maternal circulation and disappears from the circulation immediately after delivery. It has growth-promoting activity, is immunologically similar to human growth hormone, and inhibits maternal insulin activity during pregnancy. By inhibiting glucose oxidation it can increase the glucose supply to a foetus developing in a malnourished mother. Chemical name: Lactogen, placental (12 Dec 1998) |
| placental lobes | Cotyledons of the human placenta, viewed on the maternal surface as irregularly shaped elevations or lobe's. (05 Mar 2000) |
| placental membrane | The semipermeable layer of foetal tissue separating the maternal from the foetal blood in the placenta; composed of: 1) endothelium of the foetal vessels in the chorionic villi, 2) stromata of the villi, 3) cytotrophoblast (negligible after the fifth month of gestation), and 4) syncytial trophoblast covering the villi; the placental membrane acts as a selective membrane regulating passage of substances from the maternal to the foetal blood. Synonym: placental barrier. (05 Mar 2000) |
| placental parasitic twin | Underdeveloped twin of allantoidangiopagous twin; joined by umbilical vessels. Synonym: placental parasitic twin. Origin: omphalo-+ G. Sitos, food (05 Mar 2000) |
| placental plasmodium | The syncytial outer layer of the trophoblast; site of synthesis of human chorionic gonadotropin. See: trophoblast. Synonym: placental plasmodium, plasmodial trophoblast, plasmodiotrophoblast, syncytial trophoblast, syntrophoblast. Origin: syncytium + trophoblast (05 Mar 2000) |
| placental polyp | A polyp developed from a piece of retained placenta. (05 Mar 2000) |
| placental presentation | <obstetrics> The anatomic positioning of the placenta over the cervical os (opening to the birth canal). This is an important cause of painless third trimester bleeding in the pregnant female. Many cases of placenta previa will require cesarean section delivery. (31 Dec 1997) |
| placenta |
That part of the products of conception apart from the fetus where blood from the fetus and from the mother come into intimate contact to exchange nutrients and waste. Composed of trophoblast. Together with the membranes (of the gestational sac) and the umbilical cord composes the

an organ, shaped like a flat cake, that only grows during pregnancy and provides a metabolic interchange between the fetus and mother. (The fetus takes in oxygen, food, and other substances and eliminates carbon dioxide and other wastes.) preeclampsia - a condition characterized by pregnancy-induced high blood pressure, protein in the urine, and swelling (edema) due to fluid retention. premature - a baby born before full term or 37 weeks of gestation.
