Q
Effect of CRH
A
- stimulates fetal adrenal glands to secrete cortisol
- increase E/P ratio
- myometrial contractions
- maturation of fetal organs
1
Q
Placenta hormones
A
- produces large quantities of CRH
- increases E/P ratio
2
Q
Birth process summary
A
Stage 1(effacement), stage 1(early dilation), stage 1(transition), stage 2(expulsion)
3
Q
Stage 1 effacement
A
- contractions of 30-60sec with intervals of 5-20 min
- prosteglandins soften cervical tissue
- mucus plug dislodged and bloody show happens
- bursting of amniotic sac
4
Q
Stage 1 early dilation
A
contraction of 60 sec with intervals of 1-3 min
-cervical dilation of 7cm
5
Q
Stage 1 transition
A
- final phase of stage 1 labor
- 60-90 sec contractions with 1 min intervals
- fetus descends into pelvic basin
6
Q
Stage 2 expulsion
A
- Episiotomy may e performed if necessary
- crowning
- baby rotates
7
Q
Stage 3 expulsion of placenta
A
after birth, next contractions push placenta
-contractions inhibit uterine blood flow
8
Q
Ectopic pregnancy
A
when implantation occurs outside of uterus
1) tubal pregnancies
2) abdominal pregnancies
9
Q
Tubal pregnancy
A
- when implantation occurs in oviduct
- can be very dangerous
10
Q
Abdominal pregnancies
A
- when implantation occurs in the gut, mesenteries, or ovaries
- result in fetus death, surrounded by calcium
11
Q
Human Chorionic Gonadotropin(hCG)
A
- produced by cells that come from the chorion(cytotrophoblast)
- stimulates secretion of estrogens and progesterones by placenta
12
Q
Placenta Previa
A
condition where placenta is lying unusually low in the uterus, covering the cervix. puts mother at risk for heavy bleeding
