PLACENTA Flashcards
Synthesizes and secretes estrogens, progesterone human chorionic gonadotropin, and human placental lactogen
PLACENTA
What do the placenta secretes?
estrogens
progesterone
human chorionic gonadotropin
human placental lactogen
This prolongs the viability of the corpus luteum which synthesizes progesterone and estrogen in early pregnancy until the placenta can assume the function
Human chorionic gonadotropin
The highest concentration of hCG appears during?
first trimester of pregnancy
Measurement used to detect pregnancy
hCG QUALITATIVE MEASUREMENT
Use of monoclonal antibodies to detect hCG in 1-2 days following fertilization
hCG QUALITATIVE MEASUREMENT
What do hCG qualitative measurement use?
monoclonal antibodies
It has an exact concentration of hCG from the sample
hCG QUANTITATIVE MEASUREMENT
What does Increased hCG denote?
Hydatidiform mole, choriocarcinoma, pre-eclamptic toxemia
This is a type of gestational trophoblastic disease characterized by abnormal growth of the trophoblastic tissue
Hydatidiform mole
In hydatidiform mole, the egg fertilized by the sperm is an ___________________?
empty egg
This is almost the same with hydatidiform mole?
Pre-eclamptic toxemia
the cancer cells invade the uterine walls and the cancer cells metastasized
Choriocarcinoma
This is otherwise known as threatened miscarriage
Threatened abortion
Threatened abortion is AKA?
threatened miscarriage
threatened miscarriage is usually at?
20th week gestation
What is the manifestation of threatened abortion?
Vaginal bleeding?
is common where fertilized egg was implanted outside of the uterus?
Ectopic pregnancy
This is used to monitor success of surgery and chemotherapy
hCG
This functions with hCG to produce estrogen and progesterone during pregnancy
HUMAN PLACENTAL LACTOGEN (HPL
HPL reaches its highest level at?
Near term
What do HPL reflects?
integrity of placental function
Decreased HPL suggestive of _____________ and ___________________?
placental malfunction
potential fetal distress
