Flashcards in Exam #1 Deck (45):
terms for the top and bottom of the uterus
layer of the uterus that gets shed during a period
function of the myometrium
expelling the fetus during labor by muscle contractions
the type of pelvis shape that is most preferred for delivery
type of pelvis that is not favorable for delivery and commonly seen in men
how many sperm are released during ejaculation?
where does fertilization occur?
ampulla (outer third of the uterine tube)
fetal side of the placenta
maternal side of the placenta
biochemical marker of pregnancy that can be detected by pregnancy tests. Detectable 8-10 days of conception
human chorionic gonadotropin (hCG)
what is the umbilical cord made of?
2 arteries and one vein
function of the arteries in the umbilical cord
arteries carry deoxygenated blood and waste away form the fetus
function of the vein in the umbilical cord
veins carry oxygenated blood and provides oxygen to the fetus
what is whartons jelly?
fluid that surrounds vessels in the umbilical cord
amount of amniotic fluid that is present at term
scant amount of amniotic fluid. less that 50% of expected amount of fluid. Renal issues possible.
flood of fluid when water breaks is called? Can be up to 2000ml at one time.
the two membranes that hold the amniotic fluid
chorion and amnion
the first 2 weeks after conception is called?
3rd - 8th week after conception is called
Embryonic Period (the most critical time)
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
embryonic period hallmark?
Fetal Heart beat around week 5
fetal heart rate in the first trimester
160-170 bpm, then slows to 110-160bpm
The period that begins at 9 weeks and continues until birth
fetal period hallmark:
fetal circulatory system (fetal bypass is present due to non-functioning lungs) + respiratory system + neuromuscular system
connects the pulmonary artery to the aorta (bypasses lungs)
connects the umbilical vein and inferior vena cava bypassing the liver
the opening between the right and left atria (not ventricles) of heart bypassing the lungs
what is the Lecithin (L)/ Sphingomyelin (S) ratio supposed to be to determine maturity of the fetus
2:1 usually at 35 weeks
The L/S ratio that is preferred for diabetes patients
at what week does the fetus begin practicing respiratory movements?
what what time does quickening usually begin?
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
what protects the skin of the fetus?
vernix caseosa (thick at 24 weeks and scant by term)
the very fine hairs that appear at 12 weeks and cover the entire body by week 20, thins by week 28
lanugo - insulation
characteristics of dizygotic twins
two zygotes, placentas, amnions + chorions, fraternal twins
characteristics of monozygotic twins
develop from one ovum which divides
same sex, same genotype
2 embryos, 2 amnions, 1 chorion, 1 placenta
location of the fungus at 20 weeks and 36 weeks
36- xiphoid process
what is lightening?
When the funds drops between week 38-40 to defend and engage in the pelvis.
when would we be concerned about fundal growth?
if the size of the fundus does not measure within 2 weeks of a good due date
the color of the cervix changes to a bluish/pruple color
when the cervix softens
What is the purpose of the mucus plug when the cervical glands proliferate?
A barrier against bacterial invasion in pregnancy
the white or slightly gray mucoid discharge that occurs in response to higher levels of estrogen and progesterone
