PHLB09 2011 Lecture 2
WHAT'S A FETUS?
oStage 1:
Sperm and egg come together during conception
oStage 2 (days 1-12):
Zygote travels down fallopian tube, implants in uterus (becomes
a blastocyst)
40% of zygotes fail to implant
20% more fail to stay implanted (miscarry)
oStage 3: Embryogenesis (weeks 2-12)
By week 9 spontaneous (reflexes) movements can be detected
Embryo measures ~ 3/4 inch
Picture in the powerpoint shows that the visual appearance of
an embryo is "merky". Looks similar to a cow, a fish, a bird, etc
oStage 4: Fetal development (weeks 12-40)
Week 20 - "quickening" (perceived)
Quickening can happen to mothers who've had 2 or more
children in week 22 because muscles aren't as strong as they were
during first pregnancy
Week 22 - viability (20-35% chance)
Week 30 - brain activity associated with sleeping/waking. Brain
activity is primitive and minimal...mostly to due with csleep cycles
oFirst trimester (weeks 1-12)
oSecond trimester (12-26)
oThird trimester(26-40)
ABORTION
oAbortion: first trimester
Medical abortion: morning after pill, pharmaceuticals to induce
abortion
Surgical abortion: suction evacuation, dissection and Curettage
(break of fetus sac and remove it with another tool)
oCoin from Cyrene depicting Silphium
Greek colony called Cyrene. Silphium was an abortiscitient,
induced menstruation after conception
An example of many civilizations where abortion was just a
normal part of life
oIs it just a bunch of cells? Then why are we having emotional
responses to abortion? Perhaps they're not appropriate responses. If it is
something that isn't wrong, then they can be inappropriate emotions
oSecond trimester: saline injection in amniotic fluid followed by induced
delivery
oThird trimester: IDX - Intact Dilation Extraction
Fetus' head is evacuated to allow for induced delivery
ABORTION RATES
o~ 42 million abortions annually worldwide

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
