| placenta tripartita | A placenta consisting of three parts almost entirely separate, being joined together only by the blood vessels of the umbilical cord; the foetus is single. Synonym: placenta triloba, placenta triplex. (05 Mar 2000) |

| placenta triplex | A placenta consisting of three parts almost entirely separate, being joined together only by the blood vessels of the umbilical cord; the foetus is single. Synonym: placenta triloba, placenta triplex. (05 Mar 2000) |
| placenta uterina | <anatomy> The part of the placenta derived from the uterine tissue. See: placenta. Synonym: maternal placenta, placenta uterina. (05 Mar 2000) |
| placenta velamentosa | A placenta in which the umbilical cord is attached to the adjoining membranes, with the umbilical vessels spread out and entering the placenta independently. (05 Mar 2000) |
| cotyledonary placenta | <plant biology> A placenta in which the substance is divided into lobes or cotyledons. (05 Mar 2000) |
| haemochorial placenta | <gynaecology> A type of placenta where the chorion, or membrane enclosing the foetus, comes in direct contact with the mother's blood. Humans have haemochorial placentas. (09 Oct 1997) |
| haemoendothelial placenta | <gynaecology> A haemoendothelial placenta is a type of placenta in which the inner lining (endothelium) of the capillaries of the chorion (membrane enclosing the foetus) comes in direct contact with the mother's blood. (09 Oct 1997) |
| haemomonochorial placenta | <obstetrics> A haemomonochorial placenta is a type of haemochorial placenta (placenta where the chorion, or membrane enclosing the foetus, comes in direct contact with the mother's blood) where a single layer of trophoblast tissue separates the mother's blood from the blood capillaries of the foetus. (09 Oct 1997) |
| Schultze's placenta | A placenta that appears at the vulva with the glistening foetal surface (amnion) presenting. (05 Mar 2000) |
| horseshoe placenta | An exaggerated placenta reniformis curved in the form of a horseshoe; present in some twin pregnancies. (05 Mar 2000) |
| spontaneous correction of placenta previa | The upward "migration" of the placenta away from the internal os by the differential growth rates of upper and lower uterine segments. (05 Mar 2000) |
| nondeciduous placenta | A placenta in which the foetal placenta is cast off, leaving the uterine mucosa intact (e.g., an epitheliochorial placenta). (05 Mar 2000) |
| succenturiate placenta | An extra placenta separate from the main placenta. In anatomy succenturiate means substituting for or accessory to an organ. In this case, a succenturiate placenta is an accessory placenta. (12 Dec 1998) |
| deciduate placenta | A placenta in which the maternal decidua is cast off with the foetal placenta. (05 Mar 2000) |
| supernumerary placenta | A succenturiate or accessory placenta. (12 Dec 1998) |
