endometrium

3

function of the myometrium

expelling the fetus during labor by muscle contractions

where does fertilization occur?

ampulla (outer third of the uterine tube)

8

fetal side of the placenta

shiny shultz

9

maternal side of the placenta

dirty duncan

10

biochemical marker of pregnancy that can be detected by pregnancy tests. Detectable 8-10 days of conception

human chorionic gonadotropin (hCG)

11

what is the umbilical cord made of?

2 arteries and one vein

12

function of the arteries in the umbilical cord

arteries carry deoxygenated blood and waste away form the fetus

13

function of the vein in the umbilical cord

veins carry oxygenated blood and provides oxygen to the fetus

14

what is whartons jelly?

fluid that surrounds vessels in the umbilical cord

15

amount of amniotic fluid that is present at term

500-1200ml

16

scant amount of amniotic fluid. less that 50% of expected amount of fluid. Renal issues possible.

Oligohydramnios

17

flood of fluid when water breaks is called? Can be up to 2000ml at one time.

Hydramnois (polyhydramnois)

18

the two membranes that hold the amniotic fluid

chorion and amnion

19

the first 2 weeks after conception is called?

Pre-Embrionic Period

20

3rd - 8th week after conception is called

Embryonic Period (the most critical time)

21

At the end of the embryonic period all organ systems are present so it is important that the pregnant women does what?

Eats folic acid for healthy neuro tube development
Stops smoking or any other kind of drugs

22

embryonic period hallmark?

Fetal Heart beat around week 5

23

fetal heart rate in the first trimester

160-170 bpm, then slows to 110-160bpm

24

The period that begins at 9 weeks and continues until birth

fetal period

25

fetal period hallmark:

fetal circulatory system (fetal bypass is present due to non-functioning lungs) + respiratory system + neuromuscular system

26

connects the pulmonary artery to the aorta (bypasses lungs)

Ductus Ateriosus

27

connects the umbilical vein and inferior vena cava bypassing the liver

Ductus Venosus

28

the opening between the right and left atria (not ventricles) of heart bypassing the lungs

week 11

32

what what time does quickening usually begin?

16-20 weeks

33

no oxygen to the fetus for a period of time is called a neurologic insult and it can result in what?

cerebral palsy, neuromuscular impairment, mental retardation, and learning diabilities

34

When the funds drops between week 38-40 to defend and engage in the pelvis.
