Define abrupt placentae. ✔️Bleeding from a normally situated placenta as a result of its complete or
partial detachment after the 20th week of gestation.
diamniotic ✔️multiple pregnancy with two amniotic sacs
Acrania ✔️partial or complete absence of the cranium
Anembryonic (blighted ovum) ✔️gestational sac without an embryo
Define amniocentesis. ✔️Aspiration of a sample of amniotic fluid through the mother's abdomen for
diagnostic analysis of fetal genetics, maturity, and/or disease.
dichorionic ✔️multiple pregnancy with two chorionic sacs
Define anencephaly. ✔️A neural tube defect where absence of the brain, including the cerebrum, the
cerebellum, and basal ganglia, may be present.
embryologic age ✔️age calculated from when conception occurs
Anencephaly ✔️congenital absence of the brain and cranial vault with the cerebral hemispheres
missing or reduced to small masses
Define aneuploidy. ✔️Fetal syndromes associated with an abnormal number of chromosomes.
bowel herniation ✔️during the first trimester, the bowel normally herniates outside the abdominal
cavity between 8 and 12 weeks
, menstrual age ✔️length of time calculated fro the first day of the LMP to the point at which the
pregnancy is being assessed
Define cerclage. ✔️The ligatures around the cervix uteri used to treat cervical incompetence during
pregnancy.
monoamniotic ✔️multiple pregnancy with one amniotic sac
cephalocele ✔️protrustion of the brain from the cranial cavity
Define embryonic age (or conception age). ✔️Age of embryo stated as time from day of conception.
monochorionic ✔️multiple pregnancy with one chorionic sac
complete abortion ✔️complete expulsion of all products of conception, including embryo and deciduas
corpus luteum cyst ✔️a physiologic cyst that develops within the ovary after ovulation, secretes
progesterone and prevents menses if fertilization occurs; may persist until the 16th week of pregnancy
Define define gestational age. ✔️Length of pregnancy defined in the United States as number of weeks
from first day of last normal menstrual period (LNMP).
primary yolk sac ✔️first site of formation os RBC that will nourish the embryo
Define hydatidiform mole. ✔️Abnormal conception in which there is partial or complete conversion of
the chorionic villi into grape like vesicles.
secondary yolk sac ✔️formed at 23 days when primary sac is pinched off by the extraembryonic coelom
