three types of prenatal diagnostic tests - ✅✅-ultrasound, amniocentesis, and
chorionic villus sampling (CVA)
ultrasound - ✅✅ -prenatal diagnostic technique that uses high frequency sounds to
create an image of the baby
amniocentesis - ✅✅ -Prenatal diagnostic technique involving needle puncture of
the amniotic sac to withdraw amniotic fluid for analysis; looks for chromosomal and
genetic abnormalities
,chorionic villus sampling (CVS) - ✅✅ -Prenatal diagnostic technique in which a

passive genotype-environment interaction - ✅✅ -parents provide genetic
disposition and nurturing context to foster certain qualities
evocative genotype-environment interaction - ✅✅ -parents provide genetic
predisposition for a child to evoke certain reactions in others that will influence their
development
active genotype-environment interaction - ✅✅ -parents provide genetic
predisposition that results in a child actively seeking out environmental conditions
that foster development of certain qualities
three periods of neonatal development - ✅✅-germinal, embryonic, and fetal
germinal period - ✅✅ -week 0-2
zygote created, attaches to uterus wall
embryonic period - ✅✅ -week 2-8
layers of cells form that later develop into organs and systems
fetal period - ✅✅ -month 2-9
major growth and development
teratogens - ✅✅-agents that interfere with natural growth and produce a birth
defect

- amount of teratogen
- susceptibility
When does organogenesis begin? - ✅✅-Around week 3 through week 8

- starts at onset of true labor
- ends when cervix completely dilated
- 30-45 sec contractions w 5-30 min between
- 45-60 sec contractions w 3-5 min between
- amniotic sac may rupture
delivery of baby - ✅✅-- begins when cervix dilated
- 20 min-2 hrs
delivery of placenta - ✅✅ -- 5-10 min
- contractions again
- placenta separates from uterine wall
✅✅-analgesia, anesthesia, oxytocics
three drugs used in childbirth -
Analgesia vs Anesthesia - ✅✅-drugs that relieve pain; includes narcotics,
tranquilizers, and barbiturates
anesthesia - ✅✅-drugs that blocks pain, can be general or epidural
oxytocics - ✅✅-drugs that stimulate contractions and induce labor
postpartum biological adjustments - ✅✅-involution, sleep adjustments, physical
healing
postpartum psychological adjustments - ✅✅-coordinating schedules, readjusting
social relationships, bonding with baby
pros and cons of naturalistic observation - ✅✅-pro: can observe natural behavior
con: can only study what you can see
pros and cons of case study - ✅✅-pro: rich and detailed info, especially in a rare
case
con: may not be applicable to other cases
pros and cons of surveys - ✅✅-pro: a lot of info, large sample, easy
