Concept Dis. Ch.18
Prenatal Development & Disease Assoc w/Pregnancy
| Question | Answer |
|---|---|
| mild hemolytic disease in group A/B infants or group O mothers, as a result of maternal anti-A & anti-B antibodies | ABO hemolytic disease |
| fluid within amnionic cavity surrounding the developing organism | amnionic fluid |
| fluid-filled sac surrounding embryo; one of the fetal membranes | amnionic sac |
| congenital malformation; absence of brain, cranial vault, & scalp as a result of defective closure of neural tube | anencephaly |
| stage of development of zygote in which a central cavity accumulates within the cluster of developing cells | blastocyst |
| structure connecting embryo to chorion; eventually develops into umbilical cord | body stalk |
| malignant proliferation of trophoblastic tissue | choriocarcinoma |
| layer of trophoblast & associated mesoderm that surrounds developing embryo | chorion |
| chorion with its villi & enclosed amnion, yolk sac, & developing embryo | chorionic vesicle |
| identical twins joined to one another & often share organs in common | conjoined twins |
| conjoined twins are also called | Siamese twins |
| endometrium of pregnancy | decidua |
| disturbance of blood coagulation as result of activation of coagulation mechanism & simultaneous clot lysis | disseminated intravascular coagulation syndrome |
| one or more convulsions in a pregnant woman with preeclampsia | eclampsia |
| developing human organisms from the 3rd-7th weeks of gestation | embryo |
| partial replacement of blood of infant with hemolytic disease by blood lacking antigen responsible for hemolytic disease | exchange transfusion |
| exchange transfusion is done by transfusing __ blood to an __ infant | RH- ; Rh+ |
| exchange transfusion performed to reduce intensity of hemolytic | jaundice |
| unborn offspring after 8 weeks' gestation | fetus |
| 3-layered cluster of cells that will eventually five rise to an embryo | germ disk |
| general term for all diseases characterized by abnormal trophoblast proliferation | gestational trophoblast disease |
| gestational trophoblast disease includes both choriocarcinoma and | hydatidiform mole |
| cells lining the ovarian follicles | granulosa cells |
| one of the hormone made by placenta in pregnancy having actions similar to pituitary gonadotropins | human chorionic gonadotropin (HCG) |
| one of the hormones produced by the placenta that has properties similar to pituitary growth hormone | human placental lactogen (HPL) |
| neoplastic proliferation of trophoblast associated with formation of large cystic villi | hydatidiform mole |
| group of cells that are derived from fertilized ovum & are destined to form the embryo | inner cell mass |
| aggressive hydatidiform mole that invades the uterine wall | invasive mole |
| middle germ layer of embryo, which gives rise to specific organs & tissues | mesoderm |
| mulberry-shaped solid cluster of cells formed by division of fertilized ovum | morula |
| insufficient quantity of amnionic fluid | oligohydramnios |
| florescent light treatment of jaundiced babies to reduce concentration of unconjugated bilirubin in their blood | phototherapy |
| flat disk-like structure that maintains the developing organism within the uterus | placenta |
| attachment of placenta in uterus such that it partially/completely covers the cervix | placenta previa |
| excess of amnionic fluid | polyhydramnios |
| pregnancy-related complication characterized by hypertension & proteinuria, usually after 12th week of gestation, thought to | preeclampsia |
| preeclampsia is thought to be caused by | placental dysfunction |
| cell derived from fertilized ovum that gives rise the fetal membranes & contributes to formation of placenta | trophoblast |
| attachment of umbilical cord to the fetal membranes rather than to the placenta | velamentous insertion of umbilical cord |
| sac that is formed adjacent to the germ disk & that will form the gastrointestinal tract & other important structures in the embryo | yolk sac |
| layer of acellular material surrounding the ovum | zona pellucida |
| fertilized ovum | zygote |
| fertilization or the egg occurs in the | fallopian tube |
| third through seventh weeks of development, including the formation of organ systems, is known as the | embryonic period |
| includes producing estrogen, progesterone, HCG & HPL | endocrine function of the placenta |
| late in pregnancy, amniotic fluid is primarily composed of | fetal urine |
| pregnancy following the failure of contraceptive pills or an IUD device can produce conditions ___ to embryonic development | hazardous |
| may result in ruptured tubes & profuse bleeding | ectopic pregnancy |
| are at risk for disproportionate blood distribution | identical twins |
| causes late-pregnancy bleeding, requires cesarian section, & can be hazardous to mother & child | a placenta previa |
| when one half of a pair of twins dies and is absorbed by its sibling | vanishing twin |
| most benign type of gestational trophoblast disease takes the form of | a hydatidiform mole |
| hemolytic diseases of the newborn have their pathogenesis in a malfunction of | antigens |
| Fluorescent light therapy for Rh hemolytic disease works by converting __ __ into less toxic compounds | unconjugated bilirubin |
| about 7 days after fertilization occurs, the fertilized egg is | implanted in the uterus |
| the developing organism is most vulnerable to injury from drugs, maternal infections, or other factors disturbing fetal development during | the embryonic period |
| the chorion is the outer sac | surrounding the embryo |
| chorionic villi are the | finger-like process projecting from the chorion |
| gestational trophoblast disease includes | hydatidiform mole, invasive mole, & choriocarcinoma |
