embryo development Flashcards
pre embryonic
14 days
fertilization of the zygote - nuclear fusion
ztgote becomes morula- nuclear fusion multiple times
morula becomes blastocyst
embryonic development
2-8 weeks
hormone production nutritional supply
filtration and detoxification and aldosterone
ectoderm
glands
cns/ pns/ special sense
skin
metroderm
reproduction

gametogenesis
form ovum or sperm
will contain 22 autosome
1 sex chromosome
in women
menstration

ovulation
foetal development
9 to 38 weeks
neuralation
simutisation
gastrulation
neuralation
foetal development
neural tube
vestibular system
optic product
ears
pituartry gland
somtisation
foetal development
primitive heat
limb buds - limbs of hands and legs
gastrulation
gut prouferlation
dmetica development
trophoblast produces
HCG
which will help to produce
progesterone
chorion
placenta development
implantation
HCG will stimulate the corpus letium
transformation from embyryo to gastrula
increased folds
the nueral tube begins to close up and the epidermis is formed on top of the neural tube
teratogens
factors that impact on development
and cause abnormalities
