| placenta accreta | Abnormal adherence of part or all of the placenta to the uterine wall, with partial or complete absence of the decidua basalis, especially of the spongiosum layer. (12 Dec 1998) |
|---|---|
| placenta accreta vera | The term applied when villi are juxtaposed to the myometrium. (05 Mar 2000) |
| placenta biloba | A placenta duplex in which the two parts are separated by a constriction. Synonym: placenta bipartita. (05 Mar 2000) |
| placenta bipartita | A placenta duplex in which the two parts are separated by a constriction. Synonym: placenta bipartita. (05 Mar 2000) |
| placenta circumvallata | A cup-shaped placenta with raised edges, having a thick, round, white, opaque ring around its periphery; a portion of the decidua separates the margin of the placenta from its chorionic plate; the remainder of the chorionic surface is normal in appearance, but the foetal vessels are limited in their course across the placenta by the ring. See: placenta marginata, placenta reflexa. (05 Mar 2000) |
| placenta diffusa | An abnormally thin placenta covering an unusually large area of the uterine lining. Synonym: placenta diffusa. (05 Mar 2000) |
| placenta dimidiata | A placenta consisting of two parts, almost entirely detached, being united only at the point of attachment of the cord. See: placenta biloba. Synonym: placenta dimidiata. (05 Mar 2000) |
| placenta duplex | A placenta consisting of two parts, almost entirely detached, being united only at the point of attachment of the cord. See: placenta biloba. Synonym: placenta dimidiata. (05 Mar 2000) |
| placenta extrachorales | A placenta in which the chorionic plate is limited by a thin membranous fold at the edge. (05 Mar 2000) |
| placenta fenestrata | A placenta in which there are areas of thinning, sometimes extending to entire absence of placental tissue. (05 Mar 2000) |
| placenta gonadotropin | A glycoprotein with a carbohydrate fraction composed of d-galactose and hexosamine, extracted from the urine of pregnant women and produced by the placental trophoblastic cells; its most important role appears to be stimulation, during the first trimester, of ovarian secretion of the oestrogen and progesterone required for the integrity of conceptus; it appears to play no significant role in the last two trimesters of pregnancy, as the oestrogen and progesterone are then formed by the placenta. Synonym: anterior pituitary-like hormone, choriogonadotropin, chorionic gonadotropic hormone, chorionic gonadotrophic hormone, placenta gonadotropin, placentagonadotropin. (05 Mar 2000) |
| placenta increta | A form of placenta accreta in which the chorionic villi invade the myometrium. (05 Mar 2000) |
| placenta, low | Location of the placenta in the lower part of the uterus (womb) so that the placenta partially or completely covers the cervix. Also known as a placenta previa. (12 Dec 1998) |
| placenta marginata | A placenta with raised edges, less pronounced than the placenta circumvallata. See: placenta reflexa. (05 Mar 2000) |
| placenta membranacea | An abnormally thin placenta covering an unusually large area of the uterine lining. Synonym: placenta diffusa. (05 Mar 2000) |
